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.

Interesting. Okay, so do you *also* have LTE 29/30/40 that AT&T has been adding to their phones?

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.

Anyone replaced their T-Mobile model with international unlocked?

Right now (just started looking into this) this seems like a no-brainer. Performance is much better and it's rooted!!!! I know you lose wifi calling in theory (although mine hasn't worked since I purchased it despite hours of troubleshooting and tweaking (sucks bc no coverage at home (rural)), but that can potentially be addressed by a custom rom? Thoughts?

I did the switch. Battery life is better. Speed difference is unnoticeable. Signal/Calling quality is fine. I would most likely switch back if root was available for the t-mobile model (but wouldn't if advanced calling was available for international).
Getting wifi calling + VOLTE + video calling is no small task if that matters to you (the S6's wifi calling was never ported to international models even though they shared the same chipset). It would take porting a qualcomm written csc to a exynos chipset and either porting t-mobile's custom ims implimentation or making the standard ims implimentation work with t-mobile. That being said, it has been done. The Galaxy S5 saw advanced calling from the S6 ported back, HTC's flagships have had wifi calling ported.

I had an international Note5 on T-Mobile's network. I hated not having WiFi calling and advanced messaging features and such. I was able to flash a ROM that included some of the lost features luckily, but that would not be the case here since the chipsets are different (at least not possible now). Additionally, for some reason the signal was always worse than my girlfriend's Note5 even when side-by-side. Consistently worse... I wouldn't deal with the hassle again.

hi, I switched too and I'm glad I did, battery is definitely better and I didn't notice performance differences (nor reception). I believe wifi calling hasn't been/can't be ported but some roms support VOLTE. Just be advised that samsung doesn't honor the warranty of international variants in the US hence insurance companies such as Upsie won't insure your device.

How do you switch?

You have no warranty though, and Samsung Pay can be tricky to get working.

This is the first phone I've owned that I really haven't felt the need to root. I used to want to root to disable bloatware and to change the theme of the system which I can do on the S7 edge without root. Only thing I do miss is the ad blocking with root but that's a small annoyance that I can live it. Also with the T-Mobile version you get all the necessary bands for extended range LTE which is amazing here in the LA area. Everywhere I go I have solid LTE whether it's indoors or oudoors. I also just used Samsung pay yesterday for the first time at Sprouts grocery store and it worked so easily on the first try! This pay system is flawless. The old lady behind me had a surprised look on her face when I payed that way. Got a free $20 gift card from Samsung for using it for the first time. Just my personal opinion on why the carrier branded T-Mobile version is better.

My experience with my international S6 was very similar to yours. I moved back to the states with it and signed up with T-mobile. In my gym, which is underground, I could barely get a 4G signal (or nothing at all). Emails and notifications wouldn't come through even when I was connected to 4G. I got the s7e on tmobile and although signal still isn't strong, notifications come through reliably.
Not too scientific as they are different phone models and I've never paid this observation too much mind but now that I've heard your story, I'm inclined to think that carrier specific models might be better at picking up signal on that carrier.

Been using international version for a while, returned my t-mobile version on the 20th day, by that time it was apparent to me that the t-mobile version would not be getting rooted anytime soon. In my opinion this device is much better rooted, especially since i like a lot of color schemes on my status bar and the Ads were driving me crazy. would've preferred a rooted t-mobile version, but a rooted international version is light years better than a stock version of any kind imo.

s7 edge is having trouble with TMobile's LTE mobile data

So I recently purchased s7 edge g935fd from Taiwan. The phone was working fine there in Taiwan. When I came back to the States, however, the phone seems to have trouble connecting TMobile's LTE mobile data. The LTE goes on and off , no matter where I am. The phone still says that it is connected to LTE even when the data is not loading. I tried to reset the APN setting but no avail. I also tried that sim card on my old ASUS Zenphone 2 and the LTE worked fine so it is probably not the sim card's fault. The weird thing is that I can still call, text, and even use 3g network, it's only LTE that is not working properly. Anyone got a solution to this?

Have you gone to settings>mobile networks and checked if it's set to auto connect?

I took off unlimited data from my account because **** sucks here In Aurora Colorado. Isn't worth an extra 20 a month when I got WiFi at home and at work. Plus 2gb free is cool with me. Still got bingeon
Sent from my SM-G935T using Tapatalk

I used to have a note from Verizon Unlocked, but seems they've done that on and off signal quite a lot. Since their phones from T-Mobile have everything pre-installed, you can't even delete or edit their APN.
That's why I got a phone with then GS7E works like a charm.

Oh well. Like I said even with that sht I can NEVER load a video on Netflix on my lte, I would miss flights before this crap loads. I like t-mobile because it's the only one that's "good" in my area if t-mobile is "good" I don't want to know what's bad. That's cool it works for you. But I rather pay $55 a month for text talk and 2gb of free data

I have a 935FD on TMO and never have had a problem. I actually have a 935T also, just made sure the APN's matched. The FD however, has never shown an LTE icon although it shows connected to LTE in settings. This could be to being rooted and running a custom rom. But to your main question, again, I've had no issues.

Yes, I bought an International version after realizing it would probably be some time before the 935T got root. From what I understand, and don't quote me on this, but the international version of just about anything is compatible with TMO or any other GSM network. The Note 7 should be just as compatible as my 935FD is with TMO.

No, and that is the only reason I've kept my TMO version is for the wifi calling. If the buildings where I work weren't blast proof we would have cell signal inside them. Since we don't, the wifi calling is our only Option, besides landlines of course. For all these reasons we're talking about is why I'm looking at getting an HTC 10. I'm getting tired of all the Samsung lock down on stuff.

That's why I ended up pre-ordering the ATT version

The 2 missing bands don't seem to be a big deal
Band 29 - Pertaining to cellular networks, the radio downlink is the transmission path from a cell site to the cell phone. (A frequency for Tracking you)
Band 30 - The Wireless Communications Service (WCS) 2.3ghz Frequency that is mostly used for the "ZWave type technology" (ATT Alarms - like locking doors etc.)
I'm definitely going with Galaxy Note 7 N930FD DUAL SIM Factory Unlocked! I'm sure it'll feel nice to be free and feel free from a carrier like ATT. The last few devices I've purchased I felt like a mouse caught in a trap. The S6 Edge was & will be the last carrier locked device I will ever buy. Not all may feel my pain but that's way to much money to put out and be locked out of it.

One advantage of ATT is for WHEN the devices go wrong. I have had to switch practically evert note I ever had from Note 1 through 5. They are very good at that.
That's one worry about getting the device from a 3rd party seller, for me anyway.

I didn't even know what those 2 were since googling at&t bands only shows info on the ones used for calls and LTE.

Band 30 is newer spectrum they purchased last year, it's mainly for high congestion areas and hasn't been deployed in many places yet. Not sure how significant it will be in the near future, I do know that the iPhone SE was released without it, so it can't be that important, yet. Band 29 I have no idea, haven't researched it yet. I don't think I'd be afraid of this model in terms of reception, but you lose a lot of stuff like wifi calling, VOLTE, Samsung pay, etc.
Anyone know if the bootloader is unlocked? I'd be willing to lose the AT&T stuff if I could root it.

Can you see if wifi calling works? I'm pretty sure it's no, but I wanted to hear it first hand. If it doesn't maybe it's worth a call to att tech support and maybe they can add it. Also does Samsung pay work?

i briefly owned a note 5 international device without samsung pay. to get it to work you need a ROM from a country where Samsung pay is active. Like US, UK, Australia dn i think Singapore now. At the time the only roms were from countries that hadnt activated samsung pay and therefore the app didnt work. Not the end of the world as there is android pay.
I am really interested to see how you get on with LTE without that band. Can you do a compare to an AT&T device?

So far so good today. I drive a lot for work and signal / lte has been working fine. Basically haven't noticed anything wrong with data/signal so that's a good thing. I haven't cancelled my pre order with ATT so I might compare it to that one when it comes in.
Tonight I can run speed test side by side with my wife's iPhone tonight at home. Not really sure if that would help, but I can do it.

Samsung S8 - Unlocked Phone - No Wifi Calling? What Else Am I Missing

I bought an unlocked S8 at Best Buy because it was a good deal.
However, I'm noticing AT&T is restricting Wifi calling. There isn't even an option to turn in on.
Are they preventing this? If so, can I get it turned on by them ? I'm assuming there is a ROM I could flash to get it, but I would hate nothing during flashing bricking my phone.
Any other features I'm missing? Since I have really bad coverage at my desk at work, WIFI calling is important to me. I'm considering returning the phone and going to ATT brand, but there is a $35.00 restocking fee. I feel Best Buy should have told me the downsides of an unlocked.

I didn't get any restocking fee when I returned my ATT S8. Got a full refund, no questions asked. Besides if you're just swapping out to another carrier one, I'm sure they will waive it. I have MintSim (Tmo) and WiFi calling can be enabled and works fine for me on the unlocked firmware on my Vzw S8.

AFAIK, AT&T does not allow wifi calling for non-branded phones.

Can anyone explain to my why this would be? Is there any technical reason that they cannot do this on an non branded phone or are they being difficult?
I know it could be that they are strong armming me into another 2 year agreement, but if I can't use Wifi Calling, I cannot use their service due to poor reception at work. I think it would be in their best interest to let me use this feature.
Everyone I talked to on phone and in store basically act like it should be fine.

I am slightly confident that CSC (country/carrier specific code) patch can fix this issue but you would need to look into the other section for that and I say this because it fixed VoLTE issue for some other guys...

WiFi is not possible on AT&T network with the Unlocked version of S8 phones
This may help others who are considering the Unlocked S8.
Note: As of today, no options available from either AT&T or Samsung to enable WiFi calling.
After multiple trips to AT&T, BestBuy Samsung, chat sessions with Samsung support and now calling Samsung Premium Care, I finally confirmed that the Unlocked S8 model does not have any possible software upgrade to enable WiFi calling. Why did so many not know?
Samsung:
Please revise your website to clearly state the limitation, (WiFi is not possible on AT&T network ), with the Unlocked version of your S8 phones.
What's Next?
I was told that there is nothing that Samsung can do for me but Return the phone for Refund.
Now returning this phone requires me to again pay additional cost for replacing/activating another SIM for my old phone to use during the time I process an order for my next phone. Samsung cost me hours of my time and wasted my money.

I bought an unlocked S8 at Best Buy because it was a good deal.
However, I'm noticing AT&T is restricting Wifi calling. There isn't even an option to turn in on.
Are they preventing this? If so, can I get it turned on by them ? I'm assuming there is a ROM I could flash to get it, but I would hate nothing during flashing bricking my phone.
Any other features I'm missing? Since I have really bad coverage at my desk at work, WIFI calling is important to me. I'm considering returning the phone and going to ATT brand, but there is a $35.00 restocking fee. I feel Best Buy should have told me the downsides of an unlocked.

dealing with the same thing and entirely frustrated. so much wasted time that a simple disclaimer would've saved me from.

wifi calling is a feature enabled by a carrier, not the phone brand. if you want wifi-calling, flash the relevant firmware for your carrier just like i did for VZW to get wifi-calling to work. and btw, this information was widely known by doing some research previous to purchase. i had no problem finding this out but ordered anyway with the intent to flash the firmware.

and wifi calling won't work. just gives me this message:
"Oops!
We can't turn on Wi-Fi Calling for your account. Think this message is a mistake? Ask the person who can make account changes to call us..."
After numerous calls to Samsung and AT&T you absolutely cannot enable wifi calling on the unlocked phone. Only phones purchased as AT&T branded are allowed the full feature set.
If in fact you DID buy an AT&T S8, you can unlock it and keep said features, but not in reverse of that. Which blows.

That really makes no sense.... (Not that you're lying) but there's specific firmwares for the unlocked S8's depending on carrier. the G950U1 has different CSC's depending on what carrier it's used for. Why do that if it doesn't enable that carriers features?!

flashing other carriers might work (like Tmobile), but not with ATT as they are using based on the IMEI registered with ATT brand.. so flashing any CSC won't enable it as long as you spoke to their customer care and provide your No and other ATT phone to activate Wifi calling on your number.. this is not 100% working method.. search through teh CSC selection forum there people posted a workaround.

Time I understand. You will never get that back. The SIM card issue I don't understand. Didn't you keep the old sim card from your old phone. Yes, AT&T will have to reactivate it, but they should do that for free. The only time I've had to pay is when I needed to get a new physical SIM card because the size was wrong for the phone I wanted to use. If you kept the old SIM card, you can simply reactivate it and stick it in your old phone again.

it's all tied to your IMEI, and that can't be changed. the VoLTE and Wifi Calling are non-existent unless you bought an ATT branded phone.

Guys ... I'm still looking for other options BUT this will work ....
If you have a business account you can just go in to the account and change your billing acct IMEI for your unlocked phone to an IMEI of an AT&T S8 (get one from a friend, go to the store and check out the displays, etc)
If you don't have a business acct call support , eventually you can get a person that knows what to do and they can plug in a working IMEI
This works ... works on my S7 Edge as well

Flashed unlocked phone with ATT FW. Then changed my account's imei with the imei from an ATT branded phone and that got me advanced calling options. Wifi calling will worked for about 10 seconds until ATT reads the phone's actual imei and then they turn off wifi calling. Volte will continue to work.

AT&T OTA Update Coming
All, I have just confirmed with AT&T they have made the request for an OTA update to enable WiFi Calling in the Settings Menu from Samsung. The time frame I was given as of yesterday 10/2/2017 was 14 days. So by 10/16/2017 S8 & S8+ phones should receive an OTA update that enables WiFi Calling feature.

Very interesting! This would be a life saver. Do you trust their timeframe?

Hey. I finally found the Wifi calling settings.
Phone/ Dialer > Context Menu (the three dots on top right corner) > Settings > Wi-Fi calling > And I see my three options there.
I'm on Galaxy S8 G9500U1
