Starting with te module EC600N, not responding to call or sms

IoT Modules LTE Standard Module

I connected 4G modem for the first time, everything was easy with SIM900 modem, but 2G is gone and I need to switch to 4G.
It turned on, connected to the operator, I see the response to the request, and then nothing…I call him - busy, he does not send any notifications in the chat, I send messages the same thing.
I switched on the automatic answer to calls after two rings.

OK
nothing changed.
How to make the module send commands when it is called, do I need to register in the system after each power on?

Hi @Alexander_Lipkovich
Yes, the module needs to be successfully registered to receive phone calls and text messages.

Thank you, but where can I find the sequence of commands for registration?
