Hi, this happens to my Epic Touch twice already. It suddenly not receiving any voice call and text message in the morning when I woke up. 3G and 4G data works though. I tried to turn on the Airplane mode and then turn it off, calls are still not coming thru. I have to restart the phone in order to start receiving calls. I did not root my phone nor apply any system setting to my phone. Does anyone have this problem?
