My phone has not been able to send or receive voice calls for over a week. Took to AT&T store in Malvern, Arkansas...they had to ghost my phone to send and receive calls. Got it working...in the process, my mobile data was cut off...( No internet) then I called tech support over the phone..the lady said no problem..what ever she did it got my mobile data back...but now I'm back to where I started...can't send or receive voice calls...been a AT&T customer for 20 years...pay over 350.00 a month
