EC25 LTE connection failure Unknown error (NETWORK_REGISTRATION_FAILED)

Hi all,

I have an issue with EC25 LTE modem, i want to connect network using LTE but i cannot.

I created a network interface using luci as below, but i always face with NETWORK REGISTRATION FAIL.

How could i fix this , i am suspecting sim card but i don't know how to check that i use appropriate sim card for this purpose.

Is there any way to test EC25 using AT command any pointer documentation etc.

Thanks for any help.

I plugged sim card before power on device, and it works fine.
