S6 Active Issue
I bought a S6 active from Best Buy, and I live in India, and AT&T sent me an unlock code. Everything seems to work here except call waiting and call forwarding. When I try to open phone settings I recive and error saying "Sim or network Error" I tried changing my sim and that did not work. I tried the same SIM in another phone and call forwarding/call waiting works.
It seems to be an AT&T firmware/account issue. I am running 5.0.2. Is there a way I can get this issue corrected since I am in India? Through an update? This is an issue that seems to affect a lot of people by the looks of it.
I tried chatting with support, but they transferred my three times, and were not really helpful. Can anyone please shed some light on this issue?
