UPDATE - I was able to track down the following link for the modem that is supposed to be used in the LTE version. This would give credit to the information that tech support gave me. If this is correct, the modem is completely accessible at the software level. HELL YEAH! Now here is the link.
http://www.nvidia.com/object/i500-cellular-modems-products.html
I originally called Nvidia tech support back on July 17th, 2014 to see if the LTE version would support GSM voice calling seeing as how it is factory unlocked and compatible with both AT&T and T-Mobile. They would not tell me if the phone restriction in the US was locked down by hardware or software at that time and that I would have to call back once the tablet officially hit the market.
I called today and was AMAZED when the tech told me very honestly that the restriction was at the software level. I then asked, if I were to root the device without unlocking the bootloader, and then use a different framework to expose the dialer and phone settings, would I be able to achieve making phone calls over a GSM connection....................... HE SAID YES!!!!!!
Again, being very forthcoming and stating exactly what I wanted to do, he assured me that this can be done by altering JUST the software, it is not locked down at a hardware level like the uh...cough, cough... Nexus 7 LTE. As usual, rooting MAY void the warranty....BUT he said that doing something like this would be looked at on a case by case basis for determining if these actions would indeed void the warranty. Encouraging, as he did not flat out say, if you mess something up...enjoy your new paperweight!
Praise the lord... I know not everyone needs or wants a tablet that can make calls, but if I can kill 2 birds with 1 stone, and have a way to make the 30 minutes of calls that I do per month through BLUETOOTH (don't start the whole holding a tablet to your head is stupid argument) while only carrying an awesome performing tablet, than that is fine for me.
Now to just wait for the LTE model to arrive to market and then see if any BADASS DEVELOPER can share with me how to modify the framework to expose that dialer!
Mods... just realized that I posted this to Q&A instead of General, please move if necessary.

That is very good news. I really like this tablet, but I will upgrade for the larger storage size and the ability to make a few changes and be able to use it as a phone when needed as well.
Speaking of the lte version, does anyone have confirmation its is T-Mobile and attack ONLY as I was looking at the listed cell bands and it does list the bands that others carriers use as being compatible though I saw no mention of what the actual radio chip set is (so its feasible that it isn't gsm only hardware wise)

See my updated op. You might like what you find.
According to the Nvidia Shield Tablet FAQ, there are 3 versions of the LTE tablet, only one of which supports voice. Unfortunately, the LTE bands that model supports do not appear to be the ones T-Mobile or AT&T use in the U.S.A.
Hopefully the lack of voice support on the other models will be a software restriction that can be fixed by the developer community here.

WHAT CELLULAR NETWORKS DOES THE SHIELD TABLET LTE SUPPORT?There are three versions of SHIELD tablet LTE. There is a North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.There is a second International version that works on popular European and Asian networks. It supports LTE bands 3, 7, 20 and HSPA+ bands 1, 2, 5, 8. The third version also works on popular International carriers, in addition to including voice support on compatible networks. It supports LTE bands 1, 3, 7, 20 and HSPA+ bands 1, 2, 5, 8. Check with your favorite carrier to verify coverage in your area.DOES THE SHIELD TABLET LTE SUPPORT VOICE?There is a version of the international SKU that supports voice on compatible networks, available for purchase in select regions.<<
i want to upgrade my phone and i intend to do exactly as you did .but i'd like to know does the shield tablet have an inner top speaker ? meaning if i want to put it on my ear directly to make a phone call . wouldn't everyone surrounding me hear what the other party on the end of the line is saying to me ?
what would you do about that ? i really need an answer about this matter because it's the only thing stopping me from getting this tablet
Thanks for the great news and just what I had been waiting to have clarified. Presently I am using the Samsung Galaxy Tab 7.7 P6800 which has phone capabilities.
My telephone use is very light, texting gets more usage, and I have no interest in carrying two devices. Generally I make phone calls using the speakerphone but if I ever have to take a call in a public place then I hold the tablet to my ear. Just for the record and for those who are paranoid self obsessed, nobody ever notices that my phone is 7.7", let alone point fingers at me
My brother is a heavy mobile phone user and he has a Tab 7.7" also and he will never revert to a small screen phone either.
The UK release date for the LTE version is 2nd September which is close to my birthday so I wonder what Santa will bring
This is an excellent move by Nvidia, they deserve to have outstanding success with the Shield Tablet.
In the meantime I am watching the WiFi and cracked casing threads to see how Nvidia are responding, I wouldn't be surprised if the release date is delayed while those issues are addressed.
Same situation as rebski/ I got a tab 7.7 too...
But unfortunately the shield tablet looks quite heavy, 390 grams with 8"... And doesn't have a notification led/ or an amoled screen ( on my tab 7.7, I use NoLed)
But all the ports are very useful.... Quite a dilemma with the tab Style 8.4 (290 grams)
Pre-order or wait?
So I'm looking to replace my nexus 5 with an nvidia shield... This will be my first time using a tablet as a phone. I'm rather nervous about dropping the extra hundo (100$) on a tablet when there is a chance that I wouldn't be able to use it as a replacement for my phone, sure its the best looking tablet on the US market right now and lets be honest, i'd happily drop 300$ on the none LTE version but I don't want to drop the extra money if this wont work. What do you guys think are the probability of being able to use this as a phone replacement and even if it is not capable of LTE voice in the US market is there a reasonable workaround the can be done to be able to use the tablet as a phone?

It seems like it should be possible but much may depend on location and carrier technology. But I supect that we may have to expend some cash and time in order to get it to work even in those areas where the capability seems certain. In short it probably won't make calls straight out of the box but we shall know more once the LTE models are shipped.

"DOES THE SHIELD TABLET LTE SUPPORT VOICE?

Sorry if my opinion is so vague but Nvidia themselves are not at all clear on the point.The next couple of weeks should bring some clarification and answers.
I am assuming that many people will buy the 32Gb version regardless but I will only buy it if it makes phone calls.

I got mine LTE the other day and the msg that pops up is "Calls are not supported" when using a dialer.
Live in Sweden btw
Congratulations on getting the device. That is disappointing not to have voice calls straightaway. I have been looking closely at the photos on some recent LTE reviews and they don't have the phone icon. So what is this SKU that is supposed to be available for purchase I wonder? No doubt we will find out shortly. In the meantime enjoy your tablet.

Got this reply from Support today.
Thank you for the update.
I checked this case further & the current Shield tablet you have purchased with the P/N 940-81761-2505-200 is for “SHIELD tablet LTE Europe (EU / UK Adaptor)” which is data only and no Voice feature supported.
For voice you would need to go for SHIELD tablet Voice (E.U. Adaptor) - which is not yet released. Hope this helps.

Thanks for the information. Nvidia is making this harder that it seemingly need be. They should have clarified this from the outset . I think that the sum total of the issues with this device means that I shall look to the Sony Xperia Z3 Compact Tablet as my likely next device.
I hope that you were not completely counting on making phone calls, if so then this is a bummer bombshell for you.

I bought the Wifi version and had to return it due to the Wifi issue. It's widely known and posted in Geo Force forum (NVidia own forum site) and no response from NVidia.
As much as I like the Shield Tablet, if NVidia won't fix it, I won't buy it.
I completely share your views. When this device was first announced I couldn't wait to buy one, so it is despondent to watch the enthusiasm evaporate. Also disappointing as I had expected much more from Nvidia. Isn't there a 64 bit version on the drawing board? Perhaps with the Shield Mark II they will get it right.

The idea was to replace my phone so yeah i was, started the process to return the device until i can grab one knowing i can make phone calls.
Other than this i havnt had any issues with either battery, wifi or cracked edges even the buttons feels different compared to 16gb version.
I simply love the tablet but doesnt help if i can only text people lol
Ill stick to my old broken phone until they get this sorted and get a new tablet then

Well that leaves 2 options then, Return it and wait for the voice version or keep it and wait for their adapter
I recently had a conversation with Nvidia regarding voice support on LTE devices in the United States. Here is what they had to say (names removed to protect privacy)...
Hello ----,
Thank you for contacting NVIDIA Customer Care.
My name is ----- and I will be assisting with your query.
From your e-mail, I understand that you would like to know, if the SHIELD Tablet LTE (USA/International) version supports voice.
I would like to inform you that the North American version of the SHIELD Tablet LTE doesn't support voice calls.
There are 2 International versions of SHIELD tablet LTE :
1. International version that works on popular European and Asian networks. It supports LTE bands 3, 7, 20 and HSPA+ bands 1, 2, 5, 8.
2. This also works on popular International carriers, in addition to including voice support on compatible networks. It supports LTE bands 1, 3, 7, 20 and HSPA+ bands 1, 2, 5, 8.
Hence, there is no International version that supports voice calls on LTE band 4 and/or HSPA band 4.
Please let me know, if this information was helpful. In case, if you have any further questions, please reply to this e-mail, so that I can assist you further.
Looking forward for your update.
Best Regards,

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!

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.

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

Though the phone is automatically cdma unlocked on android 6.0.1 roms, the bands are still disabled. I suggest following DrPhant0m's advice and look into the posted link above.

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!

Various websites confirm its compatible with LTE band 17. My other phone connects to it while in my house, but the Zenfone will mostly connect to HSPA+, or sometimes LTE band 2. I cannot get it to stay connected to LTE unless I get into town or on the highway. (Actually as I'm typing, it switched to LTE band 2, but in awhile it will go back to HSPA)
If I root is there any way to unlock band 17? I'm in the US and my carrier runs off AT&T towers. I got this phone specifically because band 17 reaches far off places much better but I am unable to use it.
Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Hi!
Your correct model for band 17 should be Z012DC, the same used in Brazil.

For the time being yes you are. There is a way to unlock LTE bands on Qualcomm devices, but it seems ASUS has a fail safe built into kernel preventing it at the moment. If there is ever a custom rom developed for your phone then it maybe possible to unlock band 17. Until then no. I have been trying on my Zenfone 3 Ultra. Got as far as entering in the values for the bands I want and when I reboot it resets them to default. You can read up on it here:

Me and another user have been working on it. Maybe it might work for your phone. Always a chance.

Yeah I realize that now. Even though I'm stuck with my phone, I still can't find the z012dc for sale anywhere. Practically no seller online lists which variant it is. In fact, after a few hours of research, I never even knew there was specifically variants.

Whoa thanks man. I'll keep checking back and maybe I'll try it myself. Seems you guys are close.
I must say though, this isn't a complete deal breaker, though I am stuck with this phone anyway. The Hspa network is actually FASTER than LTE band 17 in my house. I'm just afraid if I travel somewhere and only band 17 is available I might run into some trouble. But then again, 3g or Hspa might still be able to connect.
Yeah, I know it's been asked before but I don't feel confident enough to pull the trigger on it to test. I am on Verizon, I have a SIM card I could use in it that's already activated ( currently in a iPhone 6 Plus ) I see it does support CDMA and LTE bands, So does it really work fully with no drawbacks?
Thanks
Verizon/Mi Note 2 GLOBAL EDITION
2G: cdmaOne (IS-95)
3G: CDMA2000 (IMT‑MC), 1xEV-DO
4G: Band 2 (1900MHz), Band 4 (AWS), Band 13 (700MHz)
Verizon also offers LTE on
If you presently have any friends or family living/near where you would use the phone day-to-day with an Android phone on Verizon, I think this works best if you've rooted it, download the LTE Discovery app from the Play Store and use it to determine which 4G bands you are encountering primarily "in the wild" during your day. According to Wikipedia, Verizon only offers LTE on Bands 2, 4, and 13 in the US. So in theory the Mi Note 2 GLOBAL EDITION supports all of VZW's bands.

Currently I have a iPhone 6 plus and established I use band 4 at my home and work, Global version supports all LTE bands I read. So yeah it should work right? Just pop my current sim in. I talked to another guy on this forum who posted a screen shot of it working on a pre paid Verizon sim and he said it's worked fine. There's just so little info on this phone working on Verizon and it make me nervous.

There are no reasons why it would not work. It supports all 4G LTE bands which Verizon uses, which means it should get the fastest 4G signal anywhere that Verizon's spectrum reaches. That represents the best case, as in phones sold by Verizon for use on their network can only be at most on par with it for 4G support.
It also appears to support all 3G protocols and voice protocols which Verizon uses.
Hard to say whether it will work immediately upon having your present SIM inserted. You may be required to make some kind of contact with Verizon to establish a change of handset, which may be as simple as having the phone's unique IMEI read to them over the phone (or even dialed in after phoning an automated system).
There's no need for any contact with Verizon. Just put the active SIM in and it works fine. I have my Mi Note 2 Global working just fine on Verizon including VoLTE. This required no contact with Verizon nor any inputs in the device info pages on my Verizon account online. In fact I would probably *not* provide an IMEI to Verizon as they will almost surely not allow activation with the Mi's IMEI...though I don't think they'd block it or anything.
I'm the "guy" the OP is referring to above...I've confirmed that all LTE bands including 2, 4, and 13...and CDMA 1X calls and EvDO data all work fine on this phone...not sure if it's CDMA BC0 or 1 in my area (I think it's 0) but both should work. VoLTE is also confirmed working perfectly right out of the box.
To the OP - what additional information are you looking for to determine whether or not this phone is right for you? I'm happy to help but I'm not understanding what else you might need to know as pretty much everything has been revealed vis-a-vis Verizon and the Mi Note 2 Global and it definitely works fine...if you're nervous about it I probably would suggest a different handset unless you really need the dual SIM functionality with Verizon...in which case it's either this phone or the ZTE Axon 7 that you'll be limited to...the Axon 7 is a better phone all in all IMO but is more finicky software-wise in my experience and takes a little more user tweaking to get Verizon to work as well as it should (some people have really struggled with the Axon 7 on Verizon but I had smooth sailing except that I had to use a GSM SIM for initial setup and also after OTAs to sort of "clear" the radio out). The Xiaomi Mi Note 2, on the other hand, has much better connectivity and has given me zero problems on Verizon...I'm actually really impressed with it in this respect.
But at the same time I find the screen on the Xiaomi Mi Note 2 to be grossly inferior to that of the ZTE...the speakers too. And MIUI is kind of meh but I know some people love it...but I guess that's kinda off topic!

In my case it's to improve data coverage but for most people it's because they travel internationally and need a second operator in the other country or they do it so they can have a work-related phone number and personal number in the same device.
"Vis-a-vis" just means "in relation to" for all practical purposes.
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.

Thanks @varcor . What about Video calling?
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.
Thanks.

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.

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.

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.
