Galaxy S7 Duos and Wi-Fi calling - Samsung Galaxy S7 Questions and Answers

Hi I have Galaxy S7 DUOS (dual-SIM model G930FD) which I recently rooted. I have enabled CSC features related to WifI calling but still WiFi calling option does not show up. From what I read here I might need different ROM (BTU vs EE). I am not sure I totally understand the difference between the ROMs. Could somebody please explain to me what ROM I need to get WiFi calling and what are possible implications of flashing it compared to one I have now? Thanks!
My current software build number is MMB29K.G930FXXU1APB6. I plan to use WiFi calling on T-Mobile in US.

Hey buddy you may want to ask this in the international forum. This is the Verizon forum and I'd guess the files are different on or phone then yours.

Your last & only solution if you want to use your phone, it's to root your device.
Because it's your radio which is bad. Your baseband is for only USA and not for Greece or World West Europe (WWE)
You need to root your device and change for an European Baseband.
That's why you need to know what exactly your device:
Go to settings => About =>
Phone identity
(you will see model number, and lot of infos that you will need write somewhere for giving on your next post)
Software information
(remember these infos)
and finally click "More"
You will see your baseband and more infos that you need to give also.
Give me your model number and your device serial number, and I'll give you the good way for searching

I've got a bad news for you because you cannot unlock your sim card.
In fact your phone is only use for US cellular (CDMA) not European (GSM)
Uscc is not a gsm phone the sim card slot is used for thw 4g service the phone itself is cdma
If you use "search all forums" just above and type:
Code:
Samsung galaxy s4 sch-r970 unlock
you will find a lot of posts about this subject but with all time same answer: You CANNOT
Sorry for this bad news.
Good luck

[Completed] how to enable hotspot on my sprint Note 3 without paying that montly cost.

I have a Sprint Note 3. I really need/want to have the wifi hot spot enabled. I'm completely new at this so I'm looking for a step by step procedure on hacking/rooting the phone(if that is what it is called) and then enabling the hotspot. Please help, I have been searching these forums and found some info, but more for those who already "rooted" their phone, which I don't even know how to do that. Please help.
Thanks

First, you probably need to identify if your network is a CDMA network or a GSM network, the Verizon devices are CDMA. Try finding a S7 Edge firmware for your region/carrier, then try flashing that. Do some research and make sure that there are significant differences between the model number that you actually have and the model number of the firmware that you attempt to use, you might cause a brick if you aren't careful.
