ATT phone on Tmobile - Samsung Galaxy S8 Questions and Answers

please don't get irritated this is about an S7 Active and i have had no response on the S7 active forum
i have an s7 active that was frp and network unlocked. i am trying to use this on tmobile.
my s7 active is running android 7.0 G891AUCS2BQC2
sms, mms and emails seem to work but not the wifi calling option. the wifi calling option is greyed out under settings.
i need the wifi calling option and like the S7A.
in posts regarding the S7 (not active forum) and S8 active i saw thoughts of needing to flash tmobile software to get this to work
any ideas?
thanks

You need to install the T-Mobile firmware.
even if your phone is unlocked, it is still an AT&T model

i will search here for that info. is the firmware for tmobile s7 phones the same (s7 and s7 edge) and will the firmware for the tmobile S8 active possibly work on the S7 active?
thanks

Check APN settings. If any thing else try having them flash U firmware and see if that helps
i believe proper apn is there, as for U firmware, is that firmware that comes on Unlocked phones?
thanks !

Yes it is. Just note, if they need to flash back for any reason they need to make sure to check re partition in odin or it will not flash back to Verizon firmware.

I too am looking for some pointers on this one. Does AT&T WiFi Calling, VoLTE work on a G935A on a T-Mobile ROM?

you can get it to work,you download the tmobile nougat firmware form the T-mobile Galaxy S7 edge xda forum.Then unzip it after it downloads. Also download princecosmy's odin to bypass the SHA256 error.(You can find that there too). In odin,put the AP,BL,CP,and CSC into their cooresponding slots.AP can take a while to put into tis slot but will do so eventually. As far as the wificalling,it gives an ER06-Invalid SIM,and VoLTE wont work,although Ive heard of some SM-G935F users being able to get both features working

The link which princecosmy has for Odin isn't working. Can you share a working link?
I can't for some reason my account isn't letting post links for some reason,if check in the SM-G935A to SM-G935U guide to download the ODIN

Samsung S7 edge Verizon - G935V GSM unlocked

HI Folks
I have heard that Samsung S7 edge on Verizon is by default GSM SIM unlocked. Is this correct ? dont we have to do any unlock or similar process to allow GSM sim cards to work from other carriers both domestic and international. Any limitations on this compared to a truly unlocked phone when talking of GSM/LTE features only ?
Thanks
Yes bro! It is unlocked in default. I am staying in India. I have imported s7 edge sm-g935v. It is now on android 7.p. But problem is, it has Verizon bloatware, Verizon apps, Verizon boot up logo, also say sin card is not from Verizon when I use local GSM sim card.
All the calls, messages, work perfectly. Problem is mobile data don't work properly. I tried setting internet configuration manually. Play store and apps work. But browsing internet on any browser don't work.
Let me know if there is any way to use firmware completely free from Verizon. It's annoying man!

I have heard the same, but I got S7 Edge from Verizon and is not unlocked...
so I heard this as well and randomly while giving payment asked them if I could have the 4 digit code to unlock... 5 mins latter I had code and on way it was really pretty easy =)

To remove the bloatware just install the Stock 935U firmware. That will remove all the verizon bloatware. Not to sure about the unlocking. I have heard both versions, that is GSM unlocked by default and it is locked and cannot be used on any other GSM network either.
So i have s7 edge verizon and i am currently in india. i got a vodafone sim card and it was working but the network wasn't stable. all of a sudden i cant access any network on the phone but when i insert a sim card i brought along fro africa i get roaming network.. can anyone assist? thank you

I have a SM-G935V (S7 EDGE VERIZON) USA. This is what I did, I put the Sim card in another phone (T-mobile) S7 edge, then copied the APN Network verbatim. Put the Sim back into my Verizon phone and been doing ok for almost 2yrs. The data does drop when you make or recieve a call or text message. Service is very spotty, majority of the time. If anyone knows if there is a stable rom for this situation, please let me know, I'm still on pb5

Verizon models lock out certain LTE bands from use that the network does not use, simply flashing the G935U firmware would be the best bet as it will unlock all available bands and remove all the Verizon carrier bloatware. When i first had my Verizon S7 G930V i was not able to get band 12 on T-Mobile, now that i flashed the G930U firmware i get all the bands and carrier aggregation i wasn't able to before. Same goes for the G935V and U models.

yes I Did The Same for my S7 edge. But now I cant update without The phone Rebooting after 60 seconds or so... Now I'm stuck on 6.0.1

I just used my SM-G935V in Japan with a Y!Mobile SIM card for 6 months with 0 issues. Granted, I only used it for data, but it worked exactly as I would have expected. We did have to manually input the APN info, but the Y!Mobile sales associate helped me out with it.

I'm getting updates fine on both s7 and s7 edge, i have the latest March patch as well.
i had the same problems with verizon's s7 edge in dominican republic. pop up messages told me it's not a verizon sim card and data and internet would not work. then I downloaded sm-g935U international, carrier-less rom and installed it on my phone. all of the sudden my phone became a generic s7edge phone without the verizon crap apps. no more pop up and everything worked fine right from the beginning. data and internet work flawlessly and phone became a super phone.
Love my s7 edge.
Would you know if flashing the g935U firmware would also add LTE bands 12 and 17? I want the phone to be more
compatible with AT&T. Band 17 LTE is used in my area. My Verizon Galaxy S7 Edge G935V is at Android 8.0

I have the Verizon S7 Edge G935V. I want it to have more AT&T bands as it currently lacks band 12. When you say flash with the G935U firmware I noticed there are several versions for different carriers.
Would you mean flash the 935U firmware associated with AT&T? Or would I flash the verizon version of 935U? I am guessing the AT&T 935U for more AT&T bands, ??

I have this same question. My son has my old SM-G935V bought from Verizon, but it hasn't been connected to any service. I'm looking to connect it now that he's older, but I'm not paying the $XX /m Verizon wants to add a line for my kid, so I'm looking at Mint Mobile @ $15/m. I found these U firmwares:
Samsung firmware download - find All Official Android & Samsung Updates | updato.com
Are you looking for the official Samsung software to download? At updato.com, you'll find the latest Android device updates. Check on your own!
updato.com
But, which one? Do I use the Verizon one because it's a Verizon phone originally, or do I use the Tmobile firmware since Mint runs on the Tmobile network? Thanks.
UPDATE: Nevermind, I went with the T-mobile marked ROM and it worked flawlessly, at leas to connect to Mint, the service itself is garbage though so I'm going to try ATT ROM with Boost next.

hi:
I converted the phone by flashing a special ROM then I rooted the phone, then there was a special file which worked on converting the phone from V to F.
Could you describe your steps and provide download links?
Not really possible considering the 935F uses a entirely different chipset, the G935V uses Snapdragon 820 and the G935F uses a Exynos 8890, that would never work. Perhaps you are thinking of the G935U firmware?

do ya have the links where can download special ROM
G935V to G935U
I would like to know if this can be done on my Verizon Galaxy S7 Edge G935V (Android 8.0) except
I want to convert it to the G935U to be more compatible with AT&T.
I read somewhere the hardware is the same for all U.S. versions of the S7 Edge, regardless of Verizon, AT&T, etc.
I have the phone working on Straight Talk using their AT&T sim.
Changed it from CDMA to GSM and added the APN info for Straight Talk.
The phone works but is missing LTE band 17, the one used in my area.
It uses another tower but the signal is really weak. Band 17 is really popular
LTE and in my area and the phone is sort of crippled without it.
I have read the G935U firmware for AT&T solves that problem. I am
assuming the phone would be unlocked too after flashing.
The phone currently is unlocked on the GSM side.
I have downloaded ODIN, Samsung S7 Edge drivers, and the G935U for AT&T w/ Android 8.0
Any tips or pointers would be appreciated.
Thanks, Ken
