so when someone is using wifi call it most connet to tmobile sevres vai the internet from my limited knowegle it make act some what like a vpn.
i was wondering what about unlock phones from tmobile or the ones that uses it servse does the wifi calling still works or does it call tmobile or just not work.
so what i think it does connect through to the comp throw the internet . it may work just like the free calling apps but insted of the app its just built in to the rom and connects to tmobiles sevres. we are talking software. some one some sould look at the codes of the apps and tmobiles roms. oh i was talking to tmobile and tell said they had to change the code on differnt froms but then again the people from tech supprot really know know what there talking about the just read of the screen and tells them what to tell u.
