Unlocked 9810 with 7.1 - Wifi calling?
I have a 9810, unlocked from AT&T on T-mobile which I recently installed 7.1.205 on. I have read on several forums that many people have been able to make UMA work on an unlocked 9800, however the 9800 uses UMA, the 9810 uses Wifi calling. I have also read that several users have been using Wifi calling on T-mobile with the 9810 running 7.1.190.
Is there any way to enable wifi calling on an unlocked 9810? Maybe I need to debrand it, as it still shows the AT&T startup screen on boot, even though it has a leaked ROM? Should I be running 7.1.190? Which direction should I go with this? I know it is possible, but maybe 205 doesn't have wifi calling?
Thanks in advance!

UMA = WiFi calling, just renamed for OS 7.1. But the hard part is that in order for WiFi calling to work, you have to have the correct service books installed on your phone.
Note: Debranding your phone won't help do anything, except potentially leave you with a phone that is permanently bricked, so I wouldn't bother with that.On Twitter: k_r_y_p_t_o

The new curve does still have UMA though.

I'm unaware of any hardware changes made specifically for T-Mo, or the other handful of carriers that allowed UMA. It's software related, and more specifically service books, that make it work. The carrier themselves has to allow calling to occur, and from my understanding, it's run through their servers.*
