VoLTE for G900R4 (US Cellular) - Galaxy S 5 Q&A, Help & Troubleshooting

Is there anyway to get VoLTE for a G900R4 for US Cellular. I understand it would take a firmware update from the provider, but is there anyone out there that could make a firmware update since the S5 has this capability? After the first of the year it's not gonna be possible to use CMDA on Verizon towers, so when I roam I won't be able to use the phone/sms.

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:

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.

at&t to verizon

I just picked up a used s7 edge from a at&t customer, every thing that I could find said once unlocked it would work on any network. I unlocked it via at&t, checked that it works on an at&t sim and Tmobile but it is not working on my Verizon sim and their techs can get it to work either.
Will an At&t s7 edge work on a Verizon network? if so how? Or should I find a different phone?
Thanks
Andy
That is an interesting question. I believe all the US based Snapdragon S7 and S7 Edges have the same hardware, so you would just need to flash Verizon or unlocked firmware over the AT&T image. That part is confirmed, as people have gone from V to U and A, and A to U and V. If I were you, I'd probably go for the unbranded firmware, but that's a personal preference.
The real trick is getting Verizon to properly provision it.
At&t is gsm and Verizon is cdma not compatible with cdma you need to give carrier imei that's how cdma works not just with SIM card

The US (Snapdragon) S7 and S7 edge share the same physical hardware. There is a better than average chance that if he flashes the U or V firmware, and can get Verizon to put on their network, it will fly.

Question: to convert from one firmware to another do I have to install U first? I want to convert my G935T to G935A to be able to use wi-fi calling. My phone is unlocked and everything works on At&t except for wi-fi calling (Or VoLte as I see it referred to often)

If this is your first device with AT&T to support WiFi calling, you may have to get a new SIM (or get your current SIM provisioned correctly).
So are you saying I don't need to install the G935A firmware?

Question: Flashing SM-930A to SM- 930V unlocks Verizon bands?

I apologize, I tried searching for this, but I couldnt find the answer.
Out of curiosity... if I flash my AT&T S7 Edge with the Verizon stock Rom, will that unlock all the necessary bands needed to support a Verizon simcard?
No, the AT&T S7 is missing the CDMA bands that require to run on Verizon. You would have to get either the 930V or 930U variants.

It will unlock the Verizon bands, I can personally confirm this. CDMA part gets activated too. All US S7s have the CDMA portion, its the firmware that enables or disables CDMA. For example, if you flash the T-Mobile/AT&T firmware on a Verizon or Sprint S7, the CDMA is disabled by the firmware and if you flashed the Verizon/Sprint firmware on an AT&T/T-Mobile S7, the CDMA portion is enabled by the firmware. The US unbranded Firmware has the GSM/CDMA portions enabled by default.

SM-G975U (Formally an at&t) refueses to active on Sprint

Hi everyone, title basically says it all. The phone was fully paid for and unlocked. Formally an At&t phone. I'm trying to use it on Sprint's network as it should support it but however I cannot get it to activate at all. Apparently it isn't even recognized by Sprint's system at all. Any advice?
Is it because Sprint is a cdma network and at&t is a gsm network?
I could be very wrong but I dont believe gsm unlocked phones dont play well with verizon/sprint even though they have all the bands.
Let someone wiser point you in the write direction but probably flashing sprint rom on the phone would probably help. There is a thread in rom section that has you flash the unlocked firmware and then flash carrier firmware. I did this with my att unlocked 10+ and now using as a tmobile device(for carrier stuff).
Take it to a store or call ... they're picky as to letting devices on the network that aren't in their system
Gotta flash the g975u1 firmware on it...
