Suddenly sim cards was not working in my A30s device . Sim slots shows as emergency call only and No Service.
At the first time issue was resolved after resetting the phone. Again after few weeks same issue occurred. But pervious resetting not worked that time. It was automatically fixed after two days. For the third time also I got the issue again. Although I did the reset, it is not working. Now I got the another few issues like fast battery draining and stuck the phone. And top part of my phone is getting heating even though wifi connection disconnected.
Please someone could give me a solution for this?
download above app and check whether your phone is PTA approved or not..
Secondly, there may be a problem with your phone "modem file". In this case update your phone or Reinstall current software version via computer.
