ATT VOLTE on G935F ? - Samsung Galaxy S7 Edge Questions and Answers

I have wanted to find a way to get VOLTE working on ATT ever since I got my S7 EDGE (G935F). I may be wrong, but My understanding is that you have to have an ATT Device in order to get it on ATT.
I am wondering if anyone has found a way to make this happen and if so, what steps could I follow to do it as well? I have tried using ATT CSC and that didn't help at all - at least not to my knowledge -
Anyone ?

The quick answer is "yes, if you are rooted using a 6.0 S7 rom"

The first post has a CSC selection tool that will let you choose the CSC (you'd pick AT&T). It also has a link for additional instructions within the first post

SM-G900R4 - US Cellular Galaxy S5 Unlock

Hello everyone,
Sorry if this was posted already - I am typing this up in between other projects and I wanted to put something out here so I wouldn't forget. This last weekend, I purchased a used Galaxy S5 CDMA phone branded by US Cellular. I searched and searched for a way to unlock it but I was not able to find anything that worked for me. My phone is currently running Android 4.4.2 and none of the *# dial codes would do anything for me. Finally I was near a local US Cellular today so I brought my phone in and they unlocked the SIM for me so I can use it with other carriers. I haven't had a chance to go through the phone yet after the unlock, but I plan on looking at it tonight when I get home to find out if I can figure out how it was unlocked so I can share that info with anyone on the site who would like to unlock their SM-G900R4. I'm hoping that during their unlocking process, the hidden menus were left visible so I can look at the phone's file structure. I'll report back as soon as I know more.

Just a quick follow up... I didn't have a chance to go through my phone extensively last night, but I did see something that may or may not be of interest. When I got my phone back after being unlocked, there was an icon for mceFramework. When I clicked on it, it ran in the upper corner of the phone and when I swiped down it said it would be uninstalled. From what I have read about it, it has really nothing to do with the unlocking of the phone though.
Depending on what time I get home tonight will determine if I get to really dig into the phone tonight or not. I'm hoping there is something I will be able to find that will be useful. The US Cellular phone is a bit different though, as I mentioned before regarding the *# codes... No matter what *# codes I try, they do not work... even something as simple as *#060# does nothing on my phone - even after being unlocked. If I find something, I'll report back.

Anyone got there s5 unlocked yet.....?
Hello, I came across this thread and just thought I'd share how I was able to unlock my Galaxy s5 Mini (US Cellular). I tried just about everything, but what finally worked was simply flashing the stock rom which can be found at the sammobile site. Use 'Odin', instructions included on the website.

Hello -- stock rom by model number. I think in most cases this is just stock Android for the carrier of specified model, minus bloatware and network lock. Well, I correct myself -- there may be some bloatware, but certainly less than what was there after performing the factory reset. The link to 'sm-g900r4' rom is at sammobile(dotcom), firmwares, search for model number -- and download latest version.
In my case, phone model is 'sm-g800r4' (US Cellular). Everywhere I looked online suggested that I had to contact US Cellular and request instructions for unlocking, but they will only do this if you have the original sim card. So, I finally flashed the stock rom using Odin, following very basic instructions (included on the rom site). After flashing, I still had the US Cellular splash screen, but my verizon sim suddenly worked with the device. Next step for me -- root and replace that ugly US Cellular splash screen with the gorgeous lollipop boot animation. Very nice.
If you need assistance with specific instructions let me know, and I can provide a quick summary.
Simple instructions, great site to join for US Cell users.

How to changh a T-Mobile Galaxy S5 into an AT&T Galaxy S5 with stock roms?

Ok so I am trying to change my unlocked T-Mobile Samsung Galaxy S5 into the AT&T version. I don't want a customer ROM. I have unlocked the T-Mobile phone with T-Mobile. Now I want to use it with ATT. yes I know I can just drop the SIM card in but this is not for me, and I need it to look just like the ATT version. This is so I can give it to my mother -in-law, not for any devious purposes but because it is the easier way to go for her to handle it.
The T-Mobile phone has 4.4.2 on it. It is unmolested. Just stock. I have looked over some forums and some post but not really seen the step by step guide. I have downloaded the Stock firmware of the phone for ATT but when I used Odin to try and flash it, it fails. I am guessing I need root access or something like that. Can anyone confirm this? Can anyone tell me how to do this?
Thank you!
So does no one know how to do this? am I asking the impossible? it cannot be that hard? Anyone point me in the right direction?

How to make Volte work on Samsung S7 edge (Sprint) for Reliance Jio

Hi,
I am totally a newbie to Android, just moved from IOS, so please bear with me.
I am trying to make Reliance Jio sim work on my Samsung S7 edge (Sprint). Data is working just fine through Reliance jio sim on my mobile. But I am not able to activate Volte on mobile, so calls are not getting through. The Volte turn on/off tab is missing. I searched on the internet and found out that Sprint's network does not support Volte, so they have disabled the tab for it.
My model is SM-G635P
What is the best way out?? Do i have to root my phone??
Thanks in advance.
I am not aware if this will work with Sprint, Carrier locked versions are a little different, plus its Snap Dragon but this is what i did.. You need to change the CSC usually but yours being a sprint one, there will be some modifications for sure , I am pretty sure you wont have an INS CSC in your phone, so you might have to change to a stock US or UK one or maybe T Mobile. I would wait for an expert to tell you that for sure
This is for Reliance JIO Users - You dont need to flash your ROM, you can change your firmware to INS CSC and it works.
1) i used the Phone Info App (Download from the Google Play Store) and saw what CSC Codes were available for me to change to.
2) I downloaded a new firmware from Sam Mobile - You can google for them entering your model no - G-935fD, i am not sure if they are available here in XDA as well
3) My phone supported India CSC (You can see supported CSC's using the Phone Info App so i downloaded the India one it could be different for others.
4) I then downloaded ODIN and used the tuorial in this forum to flash my phone and change the CSC code.
https://www.youtube.com/watch?v=7SK3IMprKVQ this is the link with a step to step guide.
5) After that i factory reset my phone and downloaded the July Update Patch.
My phone after that has been able to make calls and i can see the VOLTE symbol, depending on the firmware it should either automatically come or you might have to manually enable it.
Hope this helps everyone else also. Factory reset usually helps and downloading the latest update too..
The method above will not work with Sprint Phones. Attempting it may brick your phone.
Activating VoLTE will mostly require some work at the root level. Hope someone who has knowledge about it can help you.

People simply might not know which is why they haven't replied. I can add my two cents but I'm not really sure.
930V is the version of the S7, a USA model. It might be that as the US model, it isn't compatible with samsung pay outside the US. It could also be that as a US model you can't get updates without being on a US carrier network.
Another possibility is that it's not an S7 at all and that it's a fake phone made to look and behave like an S7. Boot the phone into download mode, as download mode phone information can't be faked. See what it says in there.
But that's just a guess, I don't know for sure.
You can use Odin to change the firmware so long as it's a compatible stock firmware (you'd have to be looking at the Snapdragon firmware) which you can find at sammobile.com

its not face it tried g930u rom installed every thing good but little bit network problem network weak and Samsung pay is international not India version
Samsung pay may be an international service, but to work it still requires collaboration between telcos and samsung.
You have a US model phone that is not officially supported outside of the US, and is not officially supports by Indian telcos. That is probably why it won't work. Whatever Samsung and Indian telcos put in place to support Samsung pay likely doesn't include US model phones being used outside the US, with a non-US SIM.
The 930V also uses a different modem to the international 930F variant, which means you won't be connecting to all the same network bands as the 930F variant, which will affect your network speed and potentially any telco services such as VoLTE and Samsung pay.
There is a reason 930V's sell for cheaper than the international 930F variant.
so there is no solution for this phone
I have a AUS version of S7 and I can confirm that I am able to use it in India for Samsung Pay
Why dont you manually update it to Android 7. This will have latest Samsung Pay installed and you should be able to use it in India
Please head to Sammobile and search firmware for SM-G930V
Australia and India both use the international variant G930F, so I'd expect it to work.

How to make my unbranded Samsung Galaxy S8 work on ATT again. Pls help!

Amin, Rajan - GCIB NY​
11:06 AM (0 minutes ago)
to me
I have an unlocked/unbranded Galaxy S8 (SM-G950U1; Baseband is G950U1UE8DUG4). I was using it on ATT but now it doesn’t work after ATT 3G upgrade. I have read that I can flash G950U firmware to my U1 phone and it will work on ATT.
Is it any G950U firmware or do I need a specific version for ATT and my region? Can you show me where to find the needed firmware?
Can someone walk me through steps on how to install the firmware (including where to find Odin and any other downloads I need).
If this will wipe my phone, is there anyway to back up my phone so that I can get all my contacts, text history, whatsapps history, apps back on the phone after flashing it? Can you also walk me through how to do this?
Will this actually work even though my IMEI is staying the same – ie even if I change the firmware, wont ATT know that the phone was not originally an ATT branded phone and thus it wont work no matter what I do?
Lastly, the only reason I am doing this is bc I really like my Galaxy s8. But the S8 only goes up to Android 9. What are some of the issues I could get using phone that only goes to Android 9? (For example, could it be that I wont be able to download new apps if they are programed for Android 10 and above)?
Im a total newbie to this. I hadn’t even heard of Odin until yesterday so please make the explanations for someone is not a tech person.

At selected Best Buys the Samsung Experience center can flash it for you.
I don't flash my Notes... as I don't wish to potentially contribute to the bricked phone threads here.
At least not yet.
