Hello everyone, I am new to the forum so if I ask stupid question please kindly advice. By the way I have been changing phone after phone trying to solve my incoming call issue where someone call me and my phone doesn't ring and go to voicemail. I use land line phone as well as using my friends phone to call my phone and it just don't ring. I have very good signal, so what could be the problem? I call ATT and have create case to solve this problem but still having problems. So I turn to android forum to see if anyone can help me with this. So far I know it's not my signal because my phone show great signals strength. Only have problem at work. I have done everything from resetting my phone to changing to different phone to remove Google account from my phone and uninstalling some apps. Thinking about joining T mobile but been reading and t mobile user too have incoming call issue. Please help!
