i just switched my phone from verizon to t-mobile. everything works fine but theres no wifi calling and it would be nice to have a t-mobile type rom so i can have that option. i've got my phone rooted fine. i just been reading and don't want to "brick" my phone. is there maybe an easier way to get wifi calling on my device? also everytime i restart my phone the verizon setup wiz runs and says verizon sim not installed, obv because i have a tmo sim now. any advice would be great.
