My phone is not able to make or receive calls, why?
But Sim Network Showing Properly.
Despite being connected to the network, I am unable to make calls or receive calls on my HTC Desire 816 Dual Sim.
When I try to make a call, the phone immediately shows "call failed" even without any ringing.
When others call my number, they report that my phone is 'disconnected or Out of coverage area'.
What is wrong? How can I correct this?
Is this a good question?
