hi i have a verizon samsung galaxy s7 i switched carriers to T-MOBILE i flashed the official t mobile rom nougat 7.0 (G930TUVU4BQG5) on the verizon s7 but now i do not have wifi calling or (volte) can someone please help thanks
All us s7's are the same hardware wise. Also as soon as you insert a Sim in a s7 it locks to that carrier. If I'm not mistaken t mobile doesn't support wifi calling. Not all carriers support it.Why would you do that? Verizon phone's are SIM-unlocked, just popping the T-Mobile SIM should have sufficed IF the network radios are supported (I know the S8 can, and I believe the S7 also can, but I'm not sure). T-Mobile's and Verizon's had different hardware, so flashing different ROMs is certainly going to mess some things up.
Verizon version lacks LTE 1/8/12/41; AT&T version adds LTE 29/30/40 but lacks LTE 13 and CDMA; T-Mobile version lacks LTE 8/41 and CDMA, and replaces WCDMA 8 with WCDMA 4; Sprint version adds LTE 25/26 but lacks LTE 7/13/20
