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

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!

I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
Hello everyone,
I am looking to upgrade from my S4 to an S7 over the next few days, and I have been trying to decide which is the better option between the Verizon model and the unlocked model. I will be using this phone on a Verizon network for now, and was leaning to the unlocked model to get rid of the Verizon bloatware. There is a chance I will be living in a different country in another year or so, so I figured the unlocked model would also give me more flexibility with my next carrier, as I had heard the Verizon model does not support all carrier frequencies. Are there any distinct advantages to going with the Verizon model over the unlocked model, or are there any other important differences I'm overlooking between these two options?
Thanks!
Unlocked how? Boot loader unlocked or carrier network (SIMM) unlocked? Verizon phones are carrier unlocked. Meaning, you can already take an AT&T SIMM and put it into the Verizon S7 and it will work.
As for removing verizon bloatware, that's only possible if you root. Unlocked is specific to the carrier only, not an unlocked bootloader. None have an unlocked bootloader that I know of.
The carrier unlocked phones also receive updates much slower than the normal ones.
https://plus.google.com/+DroidLife/posts/ENv2fH9zD7e
If you want carrier unlocked phones that get updates faster than the generic carrier unlocked phones, get the Verizon phone. As per this article, it's already carrier unlocked and it's already updated to Nougat. Might be some hoops to jump through, but it works:
http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked
The generic unlocked ones are still on Marshmallow and there is no word on if/when they'll get Nougat. Also, the Verizon one is cheaper than the generic carrier unlocked phones. Expecially if you can find a sale going on for it.
There is a hybrid rom that is debloated and works great for all models, it is posted in the vzw amd tmo s7 forums. I'm using it on two phones myself.
The U firmware has no bloat, and has all bands available for use. The main downside is that nougat still isn't out for it, and certain apps won't work if you're from Verizon such as their voicemail app.
On the plus side you get some features that Verizon charges extra for, such as caller ID built in for free.
Regardless you can flash any firmware to any S7 so long as it's the snapdragon variant.

I've been curious about the G-930U also. If you know, please tell me if these working assumptions are correct or not: The "U" has no carrier branding on it and it has no carrier "bloat" in it (although maybe some Samsung stuff). The "U" CANNOT be bootloader unlocked because it has the Snapdragon processor and at present none of the Snapdragon variations can have their bootloaders unlocked (how I hope this isn't true!). The "U" can be flashed to carrier-specific firmware, although I don't know what the advantage would be.
I'm still mostly using an XT1575, the Motorola X Play Edition 2015. It too had no carrier contamination but it's bootloader was easy to unlock. All I had to do to get it to work with Verizon was insert my nano SIM card. Do any phones still work like that?
I bought a Verizon SM-G950UZKAVZW direct from Samsung. I thought that I was buying a phone that I could take to any carrier. I'm hearing that might not be true. Does anyone have definitive, confirmed specs ie supported radio bands on all of the carrier variants as well as the upcoming intl version? Also I heard other reports that the hardware is identical and it's firmware that is limiting the phones. Not sure if that is true either. Samsung was absolutely not helpful.
Bottom line I need to know:
1 if I keep the SM-G950UZKAVZW, will I be able to use it with other carrier networks?
2 if I can use the SM-G950UZKAVZW with other carriers, what actions (if any) would I need to take to do that? (Other than swapping a sim card)
3 would the phone I currently possess be limited in any way if I were to use it with other carriers? (Limited is defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how would it be limited?
4 if I were to purchase an unlocked international model once it becomes available, would that phone be limited in any way when used on any US carrier? (Limited is again defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how?
If you aren't sure, please don't reply. There's plenty of people documenting their best guess already. I'm looking for the straight story.
Thanks for reading!
All of Verizon phones are Sim card unlocked and since there is really only 1 version of the S8/S8+ in the US (with different model #'s corresponding to the different carriers) using the phone on another carriers network is not going to be an issue. All you need to do is insert the sim card in.
http://www.gottabemobile.com/how-to-unlock-the-galaxy-s8/
As a quick note, if you have a Verizon Galaxy S8 congratulations. Your phone is already unlocked. Verizon Wireless no longer locks phones, regardless of what you might hear from friends or family. Simply drop a T-Mobile or AT&T SIM card in a Verizon model and it works. It may require manually configuring the APN settings though, so keep that in mind.

The ONLY exception that might be would be Sprint since they are CDMA as well, but who really wants to go from Verizon to Sprint?????
All 4 Major US(and subsequent sub carriers) are receiving the same version of the phone(meaning same internals). From my understanding, inserting the carriers Sim card into the verizon phone just means you start going at that point and have access to all the carriers bands
If you got an international version, it most likely would be powered by an Exynos CPU vs the Snapdragon 835 so there would be some performance differences (typically Exynos models perform marginally better based on previous history)
If you're looking for a US unlocked model - wait until next month
http://www.theverge.com/circuitbrea...-unlocked-galaxy-s8-plus-pricing-release-date
I appreciate your clear response! Would it be accurate to say that I will have just as much freedom to hop from one carrier to another using the phone I have, as opposed to purchasing the upcoming US unlocked variant?
Also, I have heard the same thing about the hardware, that all of the carrier variants are the same physical model. But some folks, including the Samsung tech support rep I spoke to (unfortunately that probably doesn't mean a whole lot) seem to think that the carrier firmware is limiting the radio bands. Do you know this to be false?
I have the Verizon version and works fine on Tmo out of the box. Have to use Verizon update software through Windows though. OTA's will never come through.
I am using Verizon GS8 on att, it works but I only get HSPA mostly. No LTE, so band is definitely capped by firmware.
I didn't have any issue receiving ota with att sim in vzw gs8
I saw a review that said the s8 gets locked to the first carrier sim it accepts. Can someone confirm swapping sims of different carriers works?

Once it becomes available? You can buy Exynos right now from other countries. Clove in UK will region unlock the phone before shipping to you in the U.S. What needs to become available?
Don't confuse the "unlocked" S8 Samsung will sell here in the U.S. in a month or so with the Exynos international variant. The "unlocked" S8 coming to the U.S. is still the bootloader locked Snapdragon version, just without carrier branding. It will be carrier unlocked but not bootloader unlocked. If you care about rooting, TWRP, ROMs, etc Exynos is what you want.
would that (Exynos international variant) phone be limited in any way when used on any US carrier?
(Limited is again defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how?

NO, except if you are on CDMA-handicapped Sprint or Verizon. If you use Sprint or Verizon be aware Exynos doesn't have 3G CDMA bands to fall back on if you can't get LTE. For AT&T or T-Mobile, YES it has all the LTE/HSPA/GSM bands.
The "international" Exynos variant can be bootloader unlocked, rooted, etc. so tons of advantages. While it has Verizon LTE bands, there's no CDMA. This means you really need Verizon VoLTE to work and I don't have the answer to that. And if you can't get LTE signal on mobile network, you won't have any signal due to no CDMA fallback. Again, only an issue because of CDMA if you stay on Verizon instead of using AT&T or T-mobile (or their network affiliates). You seem like you want to switch to another carrier? So, go ahead and do so!
EXYNOS VARIANTS LTE BANDS:
LTE Bands: FDD: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B32(1500), B66(AWS- 3) | TDD: B38(2600), B39(1900), B40(2300), B41(2500)
GSM/GPRS
850 / 900 / 1800 / 1900 MHz
3G/HSPA
850 / 900 / 1900 / 2100 MHz

Yeah I screwed up. I did confuse them.
I'm not interested in all that rooting stuff I just want a phone that pretty much works anywhere I want to take it and if it's slower on one network than another I wanna know what I'm getting myself into.

I am using Verizon GS8 on att, it works but I only get HSPA mostly. No LTE, so band is definitely capped by firmware.
I didn't have any issue receiving ota with att sim in vzw gs8

Hey guys
I'm from Brazil and I wanna buy the Verizon's S8 but I'm afraid about the 4G.
I saw that this model has the Brazil LTE frequencies, but I read here that Verizon capped the band from the firmware.
Somebody knows if I could flash via ODIN the unlocked rom that will come with the unlocked version in USA and so get the LTE free to use in any place?
I don't want to assume the risk to have a top mobile phone but don't be able to use 4G.
Thank you very much guys
Hey mredamon. Did you ever get a clear response here or somewhere else about this?
Hi, I have the xt1687 us model, and I was curious if there was anyway to add band 20 for use in the uk. Thank you.
Edit: forgot add its the unlocked version bought from motorola direct.

I wouldn't recommend it - though there appears to be a way (here for the Moto G5, but the process might be similar https://forum.xda-developers.com/g5/how-to/recovering-2g-3g-set-radio-band-to-usa-t3668767 ) you run the risk of setting the incorrect band and require a firmware flash to repair.
Easiest way to look for 4G access is to go to https://willmyphonework.net/ and enter in your device and the destination for using your device. For US devices, it suggests that EE, O2, 3 UK, Vodafone and Virgin Mobile are some of the providers that can provide 4G LTE on alternative bands over here. Please verify this info before considering purchasing a UK SIM for that carrier, if your device is carrier unlocked, or accessing that network if your carrier has a roaming agreement with them.
EDIT - further investigation for O2, at least, suggests that Band 3 support may only be present in London and large cities, and the main O2 signal is 800 MHz (Band 20), so if you're travelling around the UK, might be worth noting. However, O2 and Vodafone appear to be sharing towers, so you may get 4G/LTE signal regardless if you get switched to Vodafone's network. EE seems to have good coverage and uses the other LTE bands supported by the US devices.

Thank you very much for the response, some food for thought, cheers mate!
Yeah, I wouldn't recommend trying this will any newer Moto device... since like 2015. These bands are locked DEEP within the device, and messing with it is potentially hazardous to your device, meaning if you mess up it is possible that you will get no reception on any band or frequency. I don't think I have seen this successfully done since early Moto G LTE & G2 models, and even then there was a lot of bricked devices.
This is not just a firmware, radio software, or tweak that can be done, it involves going deep into the device with Qualcomm provisioning software (which isn't available through any normal channel) and hunt and peck at various undocumented hexadecimal registry options, which often results in no reception or even a bricked device in some cases. This isn't a Nexus 4 that literally had LTE disabled in a simple radio firmware change.
BTW, ignore all those sites that say they can unlock all LTE bands in any Qualcomm device, it will brick your Moto.
Sorry, but your best bet is just get a new device locally. A simple burner phone if your just there on vacation or for a short stay, or invest in a decent device if you plan on being there for any length of time. There are many options for devices in the EU that we don't have in the US and a relatively cheap one could be sufficient for your needs and use your Moto in WiFi mode for other stuff.
