Hi,
I have an unlocked Samsung Galaxy S7 from T-Mobile (SM-G930T). I wanted to use this phone in India with Jio as the service provider. Jio is a 4G only provider with VoLTE. Unforturnately with my S7, VoLTE does not work due to CSC of my phone being TMB. Jio supports VoLTE for phones with INS as CSC. The 4G data does work with the phone. I am hoping that it is possible to change the CSC for my phone. Please help.
Thanks in advance.
Regards,
-Muru

Dear Senior Member,
Please help me as I am stuck with the problem of mobile network in my Galaxy S6 Dual (SM-G920F). My mobile is upgraded recently with 5.1.1 ((PDA: G920FXXU2BOFL CSC: G920FOJV2BOEE CHANGELIST: 5012324 BUILD DATE: 22.06.2015) ). Main problem of my Galaxy S6 now is, when I select WCDMA/GSM or LTE/WCDMA/GSM or WCDMA, then my mobile network is not working and it shows error message "Not registered on network" and also it shows "Emergency calls only". But when I choose GSM only, then my call, message and mobile network work but internet speed is so slow. My upgradation is for that reason and now the same problem as earlier. I think so mane experts are here on Galaxy S6, Please help. I think it happens for Modem FIle or Stock firmware. Then which stock firmware is good for this problem. Please suggest.
Before flashing any ROM bring your S6 1st to your telecom provider for check-up since your S6 is still under warranty. Flashing ROM voids your warranty.

Before updating did you have lte? Idk there was the region specific network block that Samsung put on its phone. Meaning if u bought a phone from Dubai and plan to use in US, u have to put a Dubai sim and make 5 minutes call to unlock the region network block to use it in US.

Thank you Fullmetal for your reply. I am using S6 and UK written on backside of the phone. I am using it in Bangladesh. Is there any other way to unlock regional network?

Either find a uk sim or try some guides in youtube on how people unlocked other new samsungs(Note 3, 4) as should be mostly same for s6! Otherwise you'll have to pay and get it unlocked from a Samsung official shop in Bangladesh or your mobile carrier/service centre.

Same problem as before.
Model: GALAXY S6 (SM - G920FD/G920F) DUAL SIM
SIM 1 > GSM ONLY > CALL, Message & Internet (Slow speed as 2G) without problem
SIM 2 > GSM ONLY > CALL, Message & Internet (Slow speed as 2G) without problem
IF CHOOSE
SIM 1 > LTE/WCDMA/GSM(Auto connect) OR WCDMA/GSM OR WCDMA ONLY > SHOW EMERGENCY CALL ONLY
SIM 2 > LTE/WCDMA/GSM(Auto connect) OR WCDMA/GSM OR WCDMA ONLY > SHOW EMERGENCY CALL ONLY
Is it the problem of dual Sim or what?
Hello I own the 920i variant and I am looking into either a ROM or some other tweak to get VoLTE working. I do not believe it's a hardware limitation so I'm optimistic.

That link is useless for unlocked phones as they do not receive carrier's firmware. I think you'll need to contact your carrier's customer service to see if you can enable VoLTE. For example, SKT (South Korea) can enable VoLTE on an unlocked GS6 after registering the device as VoLTE-capable.
(Sorry, I should've posted this in the Q&A forum)
I have a G930A and from what I've read, I can either go with G930U or G930T.
A clean phone with the U is definitely tempting but I need WiFi calling (bad cell signal at work). The T is safer but I'll be living with Tmo bloat, and I also understand this is (for now) a 1-way upgrade because of bootloader versions.
If anyone here has the G930U on Tmo, can you confirm whether WiFi calling works or not?
Thanks!
Just as FYI, I am on the SM-G930FD (dual SIM international) , rooted and unlocked, with custom ROM and a CSC tweak (both are fron the XDA forum) , on T-Mobile USA with working (actually tested and made calls) Wi-Fi Calling.
ROM : http://forum.xda-developers.com/galaxy-s7/development/fastupdates-ontheedgelite-ux-v1-t3401422 , Thanks to @angelo27093
CSC : http://forum.xda-developers.com/galaxy-s7/development/utility-flashable-csc-selection-30-t3392949 , Thanks to @Tkkg1994
So if you think of buying S7, you can seriously consider the 930F/D or 935F/D models.
I recently switched from AT&T to T-Mobile for their North America coverage plus 140 countries my US number works, and on the 2nd SIM I keep a local SIM (prepaid) of the country I am at for LTE data. Works like a charm.

Does B12 VoLTE work on the 930F?

B12 is supported by the phone, and T-Mobile US uses it for VoLTE and Wi-Fi calling.

Got an SM-G930U the other day and I can confirm that WiFi calling and VoLTE work right out of the box as soon you put in a T-Mobile SIM card.
Darn! I should've waited. I went with 930T just to be safe.
I guess I'll wait for 930U to come with bootloaded v3 and try again.
Thanks for confirming!

Hi,
I have a Samsung s7 930T as well. I want to update to Oreo 8.0. Have found the firmware on SAMmobile. Does any one know if my sm-g930T will accept the g930f update? I assume I'll need to flash the bl, ap and all that to change csc. WIll that be included in the firmware down load? Do I just flash all that with ODIN?
Thanks!
Folks,
I have Galaxy A8 UAE version in the USA with MNVO SIM-card which is working on T-Mobile network. Of course VoLTE and VoWiFi features are unavailable on my A8 because it has wrong CSC (which is XSG). As I understand I need to change CSC code to add the features to my phone. But... as Galaxy A8 is not released in the USA there are no A8 ROM with CSC appliacble for the US. I'm wondering if there are any other ways to change CSC to one which will work with T-Mobile VoLTE (my previous Nokia 6 US-version had both features working fine with the same MNVO SIM). Could someone help me with that?
Follow the directions it works
Unfortunately this has stopped working.
