Tmobile Version has AT&T LTE support, and unlocked bootloader?

So far it looks like the Tmobile S4 has LTE/HSPA+ support for AT&T, and no real signs of a locked bootloader. Anyone else plan on buying that version and unlocking it if the bootloader is in fact unlocked?
Does anyone know of any apps that would test the LTE/HSPA+ bands the phone is capable of? I want to go into a Tmobile and use a test unit to see if I can get service with my LTE AT&T SIM.

Edit: Well, it looks like I'll be getting the Tmobile variant unsubsidized and use it on AT&T. Tmobile will unlock the phone if you pay the total cost up front. I just need to find a replacement back cover to rid myself of the stupid Tmobile logo on the back... lol.

If I had the money to buy the S4 outright for full price, I would just get an i9505.
EDIT: Spoke too soon. The i9505 doesn't support AT&T's LTE bands.
Can you post info on the source? I was also curious about this but i was thinking if we changed the radios like they did in the past that maybe we could get something working?

I put the info in the OP that I have so far; the LTE/3G radios are reported to support all of AT&T's bands. The bootloader, I'm going off of a guess since I don't think that Tmobile could afford to bribe Samsung to lock their bootloaders for them.
HMM, ok thanks for the info so far. I might have to go out and pick one up and test it.
Looks like the T-Mobile version has all the same bands and some extra ones added in. For instance the at&t only has lte bands 4&17. The tmobile version has LTE bands 1,2,4,5,7&17. Will T-Mobile unlock their phones for u??

I'm feeling like a newbie today cause I have my new T-Mobile Galaxy S4 in front of me & still playing with new features after 3 hours.
Tell me how to check to see if bootloader is unlocked and I'll do it.
Also trying to remember where we go to unlock the developer tools. Only remember that it must be clicked 7 times?
Just remembered, Settings.About Device>Build Number <Click Build Number 7 times, back out and Developer options magically appears.
Now i can go into it and toggle USB debugging. Now I only feel 95% newbie.

Has anybody tried their T-Mobile phone on AT&T yet?
If so, I have a couple of questions.
1. Can you use the T-Mobile phone to wireless tether (become a wifi hotspot) on AT&T's network? The AT&T version can be used to tether (with a simple hack). I was just wondering if a different .APK would be needed to do the same with the T-Mobile phone on AT&T's network or if the T-Mobile phone already has an APK installed that works on AT&T's network?
2. I realize an existing AT&T sim card can just simply be placed into the sim unlocked T-Mobile phone for it to work, but how would I go about changing the imei and other phone info that AT&T has in their system about the phone? In other words, would AT&T cause problems with anyone using a T-Mobile phone on their network even if the person paid full price for the phone and it is unlocked? Would it be better to have them change the system information at a store versus over the telephone?
3. It is reported that the T-Mobile phone works fine on AT&T's LTE network, has anyone verified this and does the phone show LTE when on AT&T's LTE network?
Thank you for any replies. Hopefully this information can help people decide if they want to buy the T-Mobile S4 to use on AT&T or not.

You can, for now, use PDAnet for tethering.
As far as changing the phone to appear as "unknown" to AT&T's system, don't do it without a backup of your /efs folder. I don't recommend doing it either because it's not really worth changing things around to hide that you're on a Tmobile phone, because for the most part, they don't care as long as you're paying them your monthly bill. I personally know a friend who has used her unlocked HTC Amaze on AT&T without issue (she was stuck to 2G speeds). The only way for you to have an "unknown" phone on your account is to use an international model phone such as the HTC one or the i9500 (unconfirmed that the i9300/i9500 model is entered into AT&T's system, I only hèard a rumour that AT&T has the IMEI of those phones in its system). My i9100 currently shows up as "unknown" in my bill statement.
I took a screenshot, but I don't have a link of the LTE working conformation (attached). I won't be getting my phone until I am on holiday in New Hampshire so that I can avoid the sales tax on purchasing the Tmobile variant. I would ask my parents to buy it for me, and I send them the money, but they have no technological skills whatsoëver close to asking/knowing what to ask for at the Tmobile store. Sorry guys, lol.

Unlock Sprint GS 7 for use on ATT/T-Mobile

I want to purchase a Sprint GS 7 and sim unlock to use on GSM carriers like AT&T and T-Mobile.
What is the process official and other options for sim unlock.
Never had Sprint service before, thanks for your assistance.
First step is to not stick a sprint sim card in the phone. I played around with mine without a sim card and to get the stupid vr game promo i stuck the card in and next thing it did was install all the carrier garbage bloatware automatically and it changes the boot screen and to my understanding it sim locks to the carrier that the sim card uses. Complete bullsh!t I am irate and stuck with all of this garbage bloat courtesy of sprint and the locked bootloader thanks to samsung. Im returning mine
I bought my sprint s7 full price through best buy.
First thing I did was swap the sprint Sim with my AT&T Sim (testing first Sim inserted). Prompted with invalid Sim error.
Appears the sprint phones come with activation software pre-installed that locks it to their network. You need them to unlock it from their end, no unlock codes.
When I put the sprint Sim back in, it didn't install all the bloat. It installs everything if you activate the phone; unactivated Sim, no account.
According to sprint, the phone needs to be activated on the network for 50 days and paid in full to be unlocked. They unlocked mine without meeting those standard because of poor support from a rep before I bought it.
After you get it unlocked, you can just insert any sim (gsm/cdma) after?
I don't see any settings to change the network mode.
I'd like to know the same. I'm traveling over seas in less than two week and would like to use while over seas with the local carrier. Not so much concerned with using it with other carriers domestically though.
I'm also curious if the phone can be used for data on other carries once unlocked. I wonder because with my current Sprint GS5, Sprint unlocked it, but it does not work with data when over seas. Come to find out after a lot of research, there is no solution and everybody with unlocked Sprint GS5s also cannot get data to work without wifi.
OP, you may want to keep that in mind and do your research. If Sprint's GS7 is like their GS5, you will not be able to get data on the phone with other carriers even if unlocked, unless connected to wifi.
Yes, any Sim CDMA or GSM will work. And data works perfectly for me. The s7 is the same device for every carrier where the only thing that changes is the software.
Here's a screenshot of my sprint phone on cricket with data.

With the Sprint model, there will be LTE issues overseas depending on where you go and which carrier you use.

I went to UK in 2013, had my S4 with me and was able to get data. I was not, however, able to get fast LTE speeds. Sprint cripples their LTE bands on purpose for some reason so that they become less useful on many international carriers.

The main difference between models on each carrier are bloatware they add and LTE bands they add and delete. Sprint always gets rid of useful LTE bands like LTE 7 which is a popular worldwide band.

Correct. Cricket is owned by AT&T, a carrier who did not get rid of band 7, despite the fact that they use Sprint's 3G network as well as CDMA. Do you have bands 25 and 26 as well? If so, that would be great!

You're also correct but this is a Sprint S7 network unlocked. And yes, I do. 25 and 26 are the first priority for me.

I don't actually. Knowing this I'm going to focus on attempting to add these bands (toggle them). Trying to get a hold of Sprint currently to get my MSL code.
The Galaxy S7 is DUC meaning it can be unlocked for domestic use, and it will automatically unlock tru a programming update sent OTA after the device has been active on the account(in good standing) for more than 50 days.

For those not in good standing, or who don't feel like waiting, find somebody with a Z3X-box, like myself, on craigslist. $45 (or usually in that area,) takes us 5-10 minutes, don't need root, and doesn't need to be clean. =]

##3282#
Just bought a sprint s7 yesterday since it was cheaper for me and had it unlock from an ebay listing for about $15. It was quick like 2 minutes and easy. Its done remotely on the person's end with your phone connected to computer. I'm using it on Tmobile and is working great. I get lte speeds and call quailty is great. Getting to the service menu above ##3282# you can edit the band priorities so you can have the wanted bands 1st, 2nd, and so forth. Just need the MSL# which they can get you.
If this is against the rules sorry, but just thought I give my experience with unlocking the sprint s7.
I'm trying to find detailed specs without luck, can someone please clarify which LTE bands the Sprint variant of the S7 has?
Please list all that are physically on the radio, and specify if they are actually available for use or blocked.

Verizon Use

T-MOBILE S7 Edge works on Verizon, ATT with unlocked Sim card! I also have LTE on All 3 Networks.
First question is how did you get your phone unlocked? I thought tmobile made you wait 45 days before they would unlock the phone

A lot of times if the phone is paid off, it'll unlock as long as it meets 1 requirement.
Sweet Verizon is super fast and coverage is virtually anywhere.

Verizon uses a lte sim card for data only. There will not be(shouldnt be anyway) any call support because the 935t does not have cdma, unless verizon is using different bands on newer devices like tmobile(band 12 - 700a)

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel 
 @T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
