Hey all,
I recently got my Note 4 through US Cellular SIM unlocked and when I insert another SIM from AT&T or Tmobile, the phone accepts the SIM but there isn't any setting to change the phone to global mode in the network settings area, nor is there a way to change APNs. I cannot place calls on either Tmobile or AT&T with it, which I find odd since the phone doesn't reject the SIM. Does this version not have support for GSM bands or is it something to do with US Cellular's software that prevents it from connecting to United States GSM carriers? Is there a hidden setting that I need to get into to enable GSM use? Thanks all!

Here's a screenshot of what I get when I try to change the network type to Global or GSM.

Old thread but bumpin, any news on this?
I also have bought a US Cellular Note Edge (not arrived yet) to use it in European GSM Networks. Phone was really cheap, so i thought i'll give it a try. Anyone have news on how to unlock GSM capabilities on this ? Maybe with a Rom from a GSM Edge ?

Can you let us know what your experience with the US Cellular Note Edge?
I am having the same problem

I recently spent some time on the phone with the executive assistant to the president uscellular and well I had no success in getting my phone unlocked if I understand correctly the phone is cable of gsm also. If anyone would like I can give you the number 4 this lady name Karen and you can bring her directly. I also spoke with several members of the presidents executive Support technical service and they all indicated that the machine would have to be taking it into the store to be unlocked. the weird thing was that the machine is not blacklisted, stolen nor gained in any ill gotten way but yet all with one accord further said that it would be refuse for unlocking without giving any good reason. I understand the company was sued in court and lost the battle to not unlock their phones and this seems to not affect them only one to one basis. I will find a solution to this and I will share it. I would be grateful for any help in doing meanwhile.

Hey, everybody. I hope I'm able to help... and in turn, I hope someone is able to help me.
Supposedly... newer Qualcomm-powered Android phones are inherently capable of connecting to any CDMA or GSM network. However, the different bands are enabled/disabled per the carrier's specifications. For instance, I'm a Verizon customer, and I connect to bands 4 and 13 for LTE service. However, US Cellular devices do not have band 13 enabled by default.
All hope is not yet lost, though. There is a thread (which has since been closed due to trolling/bickering) that details a method to flash the Qualcomm chip to enable/disable bands as needed. See here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 According to the information there... it seems that I'd be able to flash the CPU chip to enable band 13, and then I'd have support for all 1x / 2G / 3G / LTE bands that I'd need for Verizon. Likewise for T-Mo, Sprint, ATT, etc.
Now for my problem...
I have recently purchased a USC Note 4 (N910R4) from Amazon, though it was listed as a N910F, International Edition. It was listed as having been unlocked for use on any CDMA network. Unfortunately, the phone does not recognize my Verizon SIM, Verizon couldn't give me any information about the device, and a US Cellular support chat representative said I'd have to visit a store to check if the phone is actually unlocked. The closes USC store is several hours away in another state. The phone came with a USC SIM still in it... and it recognizes that SIM without a problem. I can't make phone calls, though... and no mobile data, either.
I had intended to use the International Version (N910F) and enable the correct bands per the thread above... and then activate the phone on my Verizon account... but the USC version should be close enough in band support that I'd be able to at least activate the phone. The USC phone supports band 4 LTE, and I get band 4 service where I'm sitting right now. If not that, the 2G and 3G band support are identical, I believe. So, I'm just doubtful that I'll be able to activate the phone just yet.
Can anyone shed light on how to verify that my new phone is actually carrier/SIM unlocked? I was hoping I'd be able to get someone to query a database of unlocked MEIDs, but for some reason, I am supposed to go to a store. I can't even call.
Any help is appreciated.

I share all your concerns sir. I too have not learned yet how to determine if USC nope for exactly carrier locked or no but I am of the firmest belief based on what I've learned from USC at various levels up to the Presidents executive team that it is indeed carrier locked. I cannot answer for yours then I believe that all under phones come in one of the two varieties and I am convinced even after the court ruling against them that they I have no intent to unlock a phone by less than forcesure. Furthermore I have no confidence that the store they may send you to has any unlocking abilities. According to the executive team that does this work in reality you must in the machine into them and prove its worthwhile to be unlocked. In my case well they cannot prove there is any malfeasance, they still choose to err on the side of caution and refuse to accept any proof then I have of the machine purchased new complete and clean but from a second party. They furthermore refuse to contact the locals that originally sold the phone and truthfully are the first corporation that ever more me so thin that I chose to unlock the bang bang myself. I remain as giddy as a schoolboy hoping to hear more good news from this post. I'm confident then I currently have the knowledge to fix the phone but do not currently have the time. I will happily update I'll with my success be crying the Blues at my failure soon.

Any updates, guys? Did flashing the ROM to allow access to additional channels work for anyone? Thinking of buying a USC Note 4 and then trying to unlock it for GSM usage.
Any news on unlocking or using on GSM networks? thx

Has anyone got any further with this? I've just bought a US cellular note 4 and my APN settings are greyed out. I'm assuming that US cellular will be difficult to deal with to get the phone unlocked especially if it has been bought from a third party. Has anyone had any luck with getting there's unlocked?
Hi!i set my Note Edge to say on Network mode:GSM/WCDMA/LTE but i can't place calls etc...has anyone an idea to make it work?
use z3x box to unlock it
To whom might be concern;
Make things short, NO, you cant use USC Note 4 on any US carrier if u look at the spec. The phone support only some GSM850 and FDD LTE band 5 (850mzh). And att/tmobile 2g voice is on gsm1700/2100 and LTE band is not match....... So that being said you are buying note 4 as Samsung Player and only good with USC and somewhat Verizon(need to hack for it to work, and stillike not all feature will work). Hope answer most you guy question

I've still got the USC Note 4. My son uses it on wifi and to watch videos that we load to local storage. In other words... no sim card installed.
If I manually update the phone to 6.0.1... what will I gain being that I'm a Verizon customer? Is the only difference that 1 band of LTE will be inaccessible? Would it actually start working for calls and some data with a verizon sim?
The whole "reprogram other-carrier Qualcomm phones to work on Verizon's bands" is frequently debunked as chasing a unicorn in the verizon forums.
Further... is the same applicable to newer phones? Could I get a newer (note 5/7) USC phone with android 6.x+ to work with verizon? (Unlocked bootloader would be my only reason to try)
Thanks!

I am leaving post paid service and going pre paid.
I since majority if prepaid US carriers are Sprint, T-Mobile and some AT&T. I want a GS 7 that will support all three carriers with as much bands possible.
Any suggestions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
Technically, any GSM unlocked phone would work on any GSM network, but that wasn't your question.
I ordered the sprint version to use with cricket (at&t network). What I read, the sprint version will support AT&T better than tmobile. In the end, once rooted, you could add in the band's not supported by default.
Music to my ears!
Will have to get the Sprint version and hope for the best.

It just seems that way, or it's because it has a better antenna in general. LTE Plus doesn't get you a stronger signal. The beamforming that helps at the cell edge is a tower-side enhancement. As long as your phone supports band 41, you're able to take advantage of LTE Plus - just not the Carrier Aggregation component.
I am very eager to see what happens in this regard as well. Sprint is notorious about locking down their phones to include very few LTE modes so that the phone is truly only for Sprint. Samsung's CDMA version of the Galaxy phones have been crippled in this way all the way up to the S6.
You can see various phones like the S4, S6, LG G4 and the S7. The S7 CMDA variant does not appear on this comparison chart yet but I'm hoping that it won't need to.
http://www.phonescoop.com/phones/compare.php?p=4066,4769,4773,5081,4928
The last phone in that comparison is the iPhone 6s Plus, which is the same no matter which carrier you use worldwide. I really, really hope Samsung does the same thing.
The only other phones with lots of LTE bands like the iPhone on Sprint is the Nexus 5s/6p and Moto X Pure.
PLEASE let LG and Samsung include all the default LTE modes by default on the CDMA versions of their phones!
Edit: nope, Sprint made Samsung get rid of the most important worldwide LTE band, 7, along with 13 and 20. LAME.

I'm thinking of buying the SM-G730P (Sprint) version of the Galaxy S7 even though I was all the years on Verizon and they are for sure the better service and have more coverage, at least here where I live, but the reason I wanna buy Sprint is just because Verizon just makes Samsung phones much more secure, and locks the boot loader, now the question is, First of all does Sprint still lock their LTE phones? And second of all, will an unlocked Sprint phone work on the Verizon network, and will it work overall perfectly when I'm aboard, on the International GSM network? And last of all is there a different in the build of this 2 phones, Verizon S7 and the Sprint S7, besides the bands

Today's news concludes that all US (Qualcomm) variants of the S7 indeed have a locked bootloader except for a select few apparently. Verizon and AT&T lock the bootloader tighter than others, such as Sprint. Sprint and T-Mobile didn't lock the bootloader themselves but rather Samsung. Samsung locked the bootloader to better add security to their consumers and there's been hints they may release an unlock kit/tool for developers but this hasn't been confirmed.
I got Sprint to unlock my G930P and works perfectly with AT&T. The S7, at a hardware level, is the same phone for all US variants where the only thing that changes is the software. Meaning a Sprint phone on the Verizon network would essentially have the same network performance as if you were to use an actual Verizon variant. Once the device is unlocked, at least for me, it knew my sim was on the AT&T network and switched the bands to AT&T on reboot.
Internationally, I'm not sure. There is an option to enable Global bands in one of the hidden menus in self-service but I'd assume it'll cover enough bands to provide you with what you need minimally. (I've never gone international before so can't say from experience)

GSM will work as expected.
LTE, however, will be crippled depending on the country you go to.
The updated spec list:
http://www.phonescoop.com/phones/phone.php?p=5081
According to that list, Sprint purposely took out three very important LTE bands: 7/13/20. Why does that matter? Because much of the world uses these three bands, especially band 7 and especially Europe! Sprint purposely crippled the LTE radio modes for this phone and I cannot understand why.
So yes, you'll probably get normal GSM and some LTE if they offer one of the other bands but Sprint purposely disabling or deleting the commonly used international LTE modes abroad is just anti-competitive and backwards.
Will rooting or unlocking this phone allow the use of the bands that were locked by Sprint?

The splash screen says LTE Plus, not LTE Advanced. LTE Plus is simply the new branding for Sprint SPARK. Was that the OPs question?
LTE Plus is not Sprint Spark , its more in depth. Carrier aggregation by antenna beam forming.
For those interested, Sprint is releasing an unlocked S7 that works on all the carriers and has a full range of US LTE bands:
http://www.phonescoop.com/articles/article.php?a=17870
I can't find any definitive answers on this. All I know is the minimum is 25, 26 and 41 but it'd be nice to know the full list. I travel internationally and without other LTE bands like band 7, it makes it tough to use it anywhere outside the US.
EDIT: Someone answered this question in another thread but it would be good to get screenshots to verify this.
m03sizlak said:
LTE Bands: 2 / 4 / 5 / 7 / 12 / 13 / 25 / 26 / 41
I've heard that the FCC filings show that the Sprint variant is not capable (tested or approved) for GSM or WCDMA, which is kind of disappointing since I travel a lot in Canada. Any confirmation on this?

This list of bands is a little better than both the Sprint variants of the LG G5 and Samsung Galaxy S7. If this phone can be unlocked, you at least have a way to go abroad and use LTE connections in much of Europe and elsewhere. Band 7 is the most common band in the world from what I understand.
I'm curious about this comment about GSM and WCDMA. Hopefully someone can verify this one way or another.

If you plan to travel outside the US during most of this time, your best options are to sell your HTC 10 and get one of the few unlocked flagship phones on Sprint's networks, assuming you want to stay with Sprint.
Here are your options:
Google Pixel
Samsung Galaxy S7 SM-930U
Samsung Galaxy S7 SM-935U
Nexus 6P or 5X
Motorola X Pure Edition
Apple iPhone
Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Thanks for the response. The thing is I'm not on Sprint and have no desire to be. I won't be in the states long. I bought the phone thinking that like most, it could be unlocked and used as needed wherever I travel to. I knew it wasn't unlocked but figured I could do it myself. Well, I've tried a number of times, and keep having an issue with the radio. Can you explain what you mean by bands being crippled? What I'm trying to find out now is whether it's possible for me to get this HTC10 completely unlocked. I think I've done everything right but maybe not. I'm kinda desperate at this point. I love this phone. And if I have to I'll return it and grab another that can be unlocked but I just have a hard time believing that the phone can't be unlocked. It's a strange concept for me. Any help or info would be appreciated.

First, go go Google and look up what LTE bands are.
Crippled LTE bands = the hardware inside the phone will not allow certain LTE bands to work unless physically altered. It doesn't matter which ROM you install, you will not unlock all the LTE bands without physical alteration. https://www.quora.com/Does-installing-different-rom-change-LTE-band-frequency
So no, HTC 10 will never be completely unlocked. Look at the list above and buy one of those phones if you want a completely unlocked phone.

I'm not sure I fully understand. Yes, I know that different chips have different bands that they work with. So, what you're saying is the Sprint HTC10 variant uses either a different chip or has some sort of other hardware configuration that is incompatible with GSM and the wider LTE bands and that no matter what I do with this phone I'll never have a truly unlocked phone? That's what I have understood, so my best option is to send it back. Ok, I get that. But I have read across tons of forums and threads of people who unlocked their Sprint 10s and are able to use them on other non-cdma carriers. So, how does that work? Are all the Sprint 10s the same or are some more limited than others? Are you essentially saying that i would have to get an unlocked/dev edition of the htc10 to be able to use GSM in other countries?
Sorry if i'm asking stupid questions here, I'm just trying to fully understand this. Thanks again for helping me out on this.
If anyone reading this knows better, please feel free to correct me.
This is my understanding of LTE bands and CDMA/GSM radios.
Phones like HTC 10, which are locked, include hardware that are built for specific usages. Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

They are software based. I have unlocked AT&T bands on my Sprint variant, 2 actually , and they worked perfectly fine. I would show you proof but I am back on T-Mobile which the Sprint HTC 10 already has LTE support for by default.

Will the Axon 7 work on Verizon's Network?
Eventually, Zte is still waiting for Verizon to give the green light. What I'm wondering is, even if Verizon hasn't given the green, would it work if I put my sim card in. The phone has all the bands.

Yeah. I was thinking about that. When the salesmen at Verizon saw my Nexus 6p they had no idea what it was and it has worked fine.
Would be nice if it worked on Veryzone and also had a BL unlock but some dreams are just never gonna happen
I hope I'm wrong so much

According to ZTE, the device has the correct antennas for CDMA usage (and FCC testing documents confirm that they tested CDMA usage). I asked an employee on the ZTE forums the clarify if it was enabled in both the hardware and software, but after watching the webinar that they posted on Youtube, they made it sound like it was disabled in the software. For now, it sounds like CDMA usage is disabled for all CDMA carriers until they get approval from Verizon and Sprint.
I'm anxious for CDMA compatibility, as this would make the A7 the first dual-SIM phone to fully support US CDMA carriers. (the OP3 only supports CDMA Band 0, missing Band 1 for whatever reason, and Sprint's Band 10)
I would be kind of surprised if the webinar were accurate as the specs on ZTE's Axon 7 sales site clearly show CDMA 0/1/10 support with no caveats. It would seem to be false advertising if these bands were disabled out of the box...but we'll see.
EvDO isn't mentioned but it's in the FCC filings and is kind of implied anyway.
Plus, Verizon is supposedly required to allow all band 13 devices on its network as a condition of their 750MHz license...so I'm pretty sure the Axon 7 will work even if not initially.
Agreed on the huge importance of the dual SIM/Verizon thing...that's a major step forward for people who want dual SIM CDMA (I count myself I that group!)
http://www.pcmag.com/review/346194/zte-axon-7
I emailed this guy for clarification and he confirmed his is working on Verizon and sent screen shots to show it...
I'm so close to ordering this phone. A lot of the places have a restocking once it is open. Just want to see if it works out of the box.
I see his phone states Verizon, but it says he is roaming. Can we get a pic with LTE or 4G on the display?
Thanks
Here is a screenshot showing mine on Verizon and LTE. Still shows as roaming though, but it's definitely LTE speed as you can see.

Yeah so I just went out for a bit. It's really unstable I believe it must be because Verizon hasn't fully certified it to use on their network. The LTE will work for about an hour then it cuts off altogether and just shows roaming. Then if you reboot the LTE is back. I'll investigate some more but for now I'm not sure I'd recommend using it on Verizon. It works much nicer on T-Mobile and ATT
My oneplus 3 shows roaming on Verizon also, but it works fine. Im just not in love with it. So it's going back for the Axon 7.

. Just got mine today and has the same little r by the status bars. Hasn't affected service at all. Only thing is I can't access data while on a call. In Detroit area recorded 60mbps download. Crazy fast. Everything else works perfectly. Sweet phone purchased from Best Buy.

Simultaneous voice and data on Verizon requires VoLTE, which won't be added until Verizon approves it for their network.
Hi everybody - I've used a dual SIM adapter with my Nexus 5x and 6 with Verizon and I've found that the "Global" and/or "LTE/GSM/CDMA (PRL)" radio modes can cause problems with Verizon...the "LTE/CDMA auto (PRL)" is the only one that works properly...I ordered an Axon 7 myself so I'll definitely be experimenting too but just in case someone wants to open the testing menu (i.e., *#*#4636#*#* , "Phone Information") and try this out I figured I'd pass it on...I'm really hoping we can get VZW working perfectly on this device!
Sometimes the Preferred Network Type menu in settings also has this option (see screenshot).
On dual SIM phones I know from my OnePlus 2 experiences the testing menu can be finicky to get to work as I think it doesn't always apply to correct SIM (It seemed to always apply to SIM one on the OP2) so maybe this won't do any good but I figure it's worth trying?
Also, airplane mode may have to me toggled after switching modes to make this work...my Nexus 5X doesn't need this step to make things work but the Nexus 6 does.
I'm in Detroit area as well. I'll have mine in the morning as I'm picking it up from BB. I'll fiddle with the settings. I have both Verizon & T-mobile.

I leave my Motorola devices on "LTE/GSM/CDMA (PRL)" (E2 and G4, and although I don't have one, the Moto X Pure defaults to it) and I have no issues connecting with Verizon. Stick it my Verizon SIM and it auto-connects, stick in my T-Mobile SIM and it auto-connects, stick Verizon back in and it auto-connects. The dual-SIM adapter might be causing the issues, as I've tried using one before, but it would force my phone into "TD-SCDMA, GSM/WCDMA and LTE" mode and neither SIM would end up connecting, and forcing it to "LTE/GSM/CDMA (PRL)" didn't fix anything. Since the A7 is natively dual-SIM, it shouldn't have the same issues.
Also, it seems that only SIM1 is CDMA enabled, SIM2 is GSM/WCDMA/LTE only.

Yeah - agree totally...without the dual SIM adapter, "Global" works just fine on all my devices too...there's no doubt the adapter is the issue.
What made me think of the radio mode issue was the commenter above that said the phone is "unstable..." - that's exactly how I'd describe the behavior of the phone in "Global" mode with the dual SIM installed. It works for a little while then goes to No Service and sometimes shows the Roaming icon for a bit, which seems to be a somewhat similar behavior he was experiencing, though a bit quicker in its onset.
I think the real issue with Verizon is activation, right? If you have a SIM from another device you can pop it in and go, but if you need a new activation is when it gets sticky with Verizon. They give the whole, "it's not in our system" line...

People who have tested the phone with a pre-activated SIM are the ones reporting the issues. Some have been lucky enough to not have any or only minor issues. I'm wondering if it has to do with the bands or frequencies people may be on in different areas.
I really wish we could get a solid answer from either ZTE, Verizon, or the users. I would really like to get this phone but can't take the chance of buying an expensive paperweight.
So I am looking to buy an international (or Latin) version of either the S10+ or the Note 10+.
I am on T-Mobile in the U.S.
1. How "bad" will it be if the phone has 3 out of T-Mobile's main bands? It only lacks 71, so what's the impact will be if I don't have band 71 on this phone with T-Mobile?
2. I read in the forum about flashing T-Mobile firmware on unlocked phones. How necessary is it? I prefer not to mess with flashing anything; done it in the past, I am not 'afraid' of it, but I just don't feel like going that route. Will I be missing anything from the T-Mobile network and services if I keep the phone in its stock ROM?
For example: Wifi Calling (important to me), VoLTE, etc. Will I have access to these features if I don't flash the carrier's firmware?
Thank you.
Band 71 is used only in rural areas where cell towers are very far apart . My phones have never used band 71. If you don't know what bands your phone typically is using you can download a free signal app from the Play Store that will show what band your phone is connected to. Unless you live in a very rural area or frequently find yourself in rural areas it's unlikely you need band 71.
Flashing T-Mobile firmware shouldn't be necessary. I don't have the international S10+ but rather the US unlocked model and I get both WiFi Calling and Volte fine without T-Mobile firmware.
I've used many different models of international unlocked phones from Xiaomi and Huawei on T-Mobile and always got both WiFi Calling and Volte to work with only one exception--the Mate 20 Pro. I had to get rid of that phone even though I really liked it because calls kept going to voicemail without the phone ever ringing first.
It turns out that on T-Mobile if your phone supports band 12 it also needs to support Volte or calls go straight to voicemail without ringing if the caller is using Volte . I never had that problem previously because in 5 years of using international unlocked phones the M20P was the first where Volte didn't work on T-Mobile.
There were lots of posts from T-Mobile customers in the XDA M20P threads about calls going straight to voicemail. I haven't read a single post about that issue with the S10+ so it's pretty safe to assume that the international S10+ works fine with Volte on T-Mobile.
Until the S8 Samsung didn't even sell a US unlocked model--everyone in the US with unlocked Samsung phones were using the international models with the Exynos chip and those phones always worked perfectly with T-Mobile which is very BYOP friendly (unlike AT&T).
The only thing you would be missing on the vanilla Samsung firmware is Visual Voicemail but last I checked you could just download the official T-Mobile Visual Voicemail app from the Play Store.
You would also receive your OTA updates from Samsung rather than T-Mobile but that's actually a plus because the unlocked Exynos models receive updates much more quickly than all of the US models including the unlocked Snapdragon models.
Sorry for the very long answer but I wanted to be thorough.
You should be fine with an international unlocked S10+ on T-Mobile. This is a much better phone than unlocked models from Google Pixel and One Plus so I would recommend going for it.
No manual flashing on your part will be necessary.
@jhs39 - Thank you for your extensive response. It is greatly appreciated!
OK, so I mostly use Band 4 with my current phone, which is one of TMB's main bands, so it seems like that indeed the lack of 71 won't be an issue.
However, how do I know if the Int. version will support VoLTE on the TMB network? I can't see anywhere any information about this phone even supports VoLTE (other than the carrier's model of course).
What about Video Calling?
Thanks again.

If the international model didn't support Volte on T-Mobile there would be posts on XDA complaining about calls going straight to voicemail without the phone ringing. There were multiple threads about that issue in the M20P section but I haven't seen a single complaint about that happening with the S10+.
This phone has been out since early Spring so if there was a problem using the international model with T-Mobile somebody would have reported it by now.
I don’t know anything about video calling though because I use T-Mobile's network via an MVNO and my carrier doesn't offer video calling.

That's odd. I'm using a mate 20X and the although it lacks bands 66 and 71 I don't get calls going to voicemail. In fact when viewing my historical phone signal via gsam app, it shows that I always receive a better signal than even the S10+ that I'm currently using. Both devices on T-Mobile USA.

BTW - is it 975F or something else?
I use Skype for Video Calling, it works fine. Mine is an SM-G9750, the best price I've seen is on Ebay. The only issue is when you first get the device you'll need to change the language since it's setup in Mandarin. A bit challenging but not a big deal. The Ebay vendor is in Houston which is where the device ships from, only takes a few days.

I must the F model. I travel to Israel with a local SIM and they use the F model, and it's the only possibility I have to use their WiFi calling while there. I am not 100% sure it'll work because of firmware but better chances with F model.

Not having bands 66 & 71 don't cause the problem with T-Mobile calls going straight to voicemail--if band 12 is supported on a phone T-Mobile assumes the phone also supports Volte and if it doesn't then you get calls going straight to voicemail.
I'm not familiar with the Mate 20X but before the M20P I had a P20 Pro, Mate 10 Pro and P10 Pro and none of those phones had an issue because T-Mobile Volte worked with all of them.
It's also possible the problem with the P20 Pro was fixed after I got rid of the phone since it was a firmware issue that was fixable in a software update . I kept mine for 6 months before throwing in the towel. The only workaround was to turn off 4G in the network settings. With 4G off you would receive all calls since Volte is a 4G function.
I personally love Huawei phones. Hopefully after Trump is gone all of the nonsense with Huawei being barred from using Google apps and bullied out of the US market will go away but they might decide selling their products here isn't worth the aggravation.
I've also used a bunch of unlocked Xiaomi phones on T-Mobile with no issues. A nice feature in MIUI is that if Volte doesn't work out of the box there's a dial code you can enter to manually enable it.
Band 66 is an offload for band 4 when band 4 traffic is high but if a phone doesn't have band 66 it just stays on 4 so not having 66 on an unlocked phone has never caused any problems for me.
Band 71 is only live in parts of the country and is relatively new. It can transmit a signal over unusually long distances and is used to provide cell coverage in rural areas where it would cost too much to build a full network of cell towers.

P20 pro was certified and worked fully on T-Mobile , most devices after that were not.
I don't think my mate 20x connected to band 12, but if it did, then yes it'll probably go straight to voicemail.

The SM-G975F is the Exynos SoC variant for Europe. The SM-G9750 has the Snapdragon SoC and dual SIM's as well. Wifi Calling will work on both devices in any region, including Israel as long as the service provider offers it. The only thing I would recommend is you do some research on Exynos vs Snapdragon SoC's in the S10. Good luck!

I am aware of the differences between the two chips.
In regards to WiFi Calling - I am a bit skeptical. This provider does have WiFi calling services, however they have a list of devices that are supported. Clearly they list devices and firmwares that they sell, not BYOD phones, and they sell the F version. I currently use ZTE Axon 7, I have WiFi calling on T-Mobile but it does not work on the Israeli network and when I try to 'register' it for this service through their app, it clearly says that the device is not supported.
That being said - I can't tell you if my phone doesn't work on their WF calling because it's not even sold in Israel. It could very well be that any version of Galaxy S10+ will be supported regardless of firmware. simply because it is sold there. Clearly there is no way to know this beforehand. I asked them, they of course can only guarantee phones that are sold by them and are on the list.
BTW - the Israeli version of the 975F is single SIM, they don't have the D/S, although I can't imagine this should have any impact of phone supporting or not supporting WF calling.
What's the difference between the F and the O, other than the region they are sold in?
Thanks.

Devices don't need to be certified by T-Mobile to work with Volte. All of my recent Xiaomi phones worked with Volte--none of the models were officially sold in the US or certified by T-Mobile. The P20 Pro was not sold in the US so there was zero reason for it to be certified by T-Mobile. The last Huawei phone officially sold here was the Mate 10 Pro. AT&T and Verizon require that devices be certified by them to work with Volte on their networks but T-Mobile does not. T-Mobile is very BYOP friendly.

Thanks for the clarification. So why is it then that same device , but using different sim card would show the Volte toggle or hide it from the user menu? Example, mate 20 does have Volte capabilities yet its missing the Volte toggle switch. I know on the Xioami devices one can enter a #*code to force it show that option. I think what makes it even more convulsing is that Huawei global versions have various region firmware via their Cust codes. Each one I noticed behaves slighly different using same T-Mobile SIM card. Cheers
You mentioned all calls went to VM on up 20pro, why do you think that was the case, you mentioned earlier that you thought possibly it may have been firmware related amongst other things.

I am aware of the differences between the two chips.
In regards to WiFi Calling - I am a bit skeptical. This provider does have WiFi calling services, however they have a list of devices that are supported. Clearly they list devices and firmwares that they sell, not BYOD phones, and they sell the F version. I currently use ZTE Axon 7, I have WiFi calling on T-Mobile but it does not work on the Israeli network and when I try to 'register' it for this service through their app, it clearly says that the device is not supported.
That being said - I can't tell you if my phone doesn't work on their WF calling because it's not even sold in Israel. It could very well be that any version of Galaxy S10+ will be supported regardless of firmware. simply because it is sold there. Clearly there is no way to know this beforehand. I asked them, they of course can only guarantee phones that are sold by them and are on the list.
BTW - the Israeli version of the 975F is single SIM, they don't have the D/S, although I can't imagine this should have any impact of phone supporting or not supporting WF calling.
What's the difference between the F and the O, other than the region they are sold in?
Thanks.

You're correct regarding Single SIM for the SM-G975F, the Dual SIM option is available in the SM-G975F/DS. I personally wouldn't consider obtaining a device in Israel if the majority of the time I'm the US. The major differences are SoC's, a minor difference in CPU Clock Speed and Cores. The SM-G975F has no FM Radio and offers fewer Primary Network capabilities. You can view a back-to-back comparison here.

This is quite different than your original question but with that being stated I would be confident enough in the SM-G9750's compatibility with the Israeli network for Wifi Calling. The worst case is not having Wifi Calling in Israel, which isn't an absolute necessity however you'll have the Snapdragon SoC which is a far better chipset with fewer bugs. For me it's the obvious choice if I were faced with your considerations.
You're most welcome

SoC, meaning the chip?
You see, your definition of "worst case not having Wifi calling" is important to me , simply because where I usually stay in Israel there is almost no reception at all (inside the house I am staying in), that's the main reason I want a device that will be able to use their Wifi calling.
Also, I looked at the eBay seller that you mention and I don't even think he carries the O model any more, all I see is the F model, unless of course I am missing something.
Thanks.

SoC is System on Chip, same as Chipset. If Wifi calling is a top priority buy the Exynos device to be certain but be advised there are numerous concerns over the chipset on XDA and other sites, plus Network Aggrigaton for Exynos in the US has issues with some T-Mobile clients. You may lose Wifi Calling or VoLTE in the US.

They still offer the SM-G9750, the link I shared is correct, not sure you missed something. The also sell the SM-G975F and SM-G975F/DS.
