Command to see how long a modem has been registered?

Is there such an AT command that can show how long a module has been registered?

I now AT+CREG, CEREG, etc…but is there any command that can show with specific amount of time, how long a modem has been registered to a mobile network?

specifically for EC20, EC25, EG25 etc.


Currently, there is no URC that automatically outputs the status of the registration network. Please query continuously after the registration is initiated by
