There is a "No Signal/No Service" icon (circle with line though it) and whenever I try to make a call, it shows "Out of Service Area". I tried configuring the APN, checking available network and shows No Service. Help!

Might be a bad cell radio or network settings, especially with multiple SM cards failing. Have you tried to put the SIM cards in a known good phone to make sure it isn't the SIM? If not, try that first.
If the issue remains, reset the network settings. If it persists, the cell radio is bad.
