Are you able to make calls, and have good signal strength, the obvious things I can think of first. It might even in be a network problem in your area, could be worth checking with AT&T, see if there's any reported ongoing problems.

I am able to make calls. I can send and receive SMS and MMS just fine as well.

Have you tried your AT&T SIM in another phone, or another carrier's SIM in your M8? Which should prove if it's the phone, SIM or the network at fault.

Tried it. Works fine.
