Thank you sir for this great explanation.

Sir I'm using sim800a module suddenly it stopped responding to AT commands.
Any idea what could be the problem?

Rx TX pins, power supply everything is OK.
Also able to Register on network.
After calling i can hear Ring ?

But it's responding to AT commands

Thanks for your video, I have a question. I have a modem once it's connected I try to make calls or send SMS but still said "Cannot make voice call without device being registered" I have a SIMcard and tested it already but still telling me this. What would it be? thanks
