8.2 AT+COPS Operator selection
This command can be used to query the present status of the ME's network registration and to determine
whether automatic or manual network selection shall be used.
Automatic mode: Lets the ME automatically search for the home operator. If successful the ME registers to the
home network and enters the IDLE mode. If the home network is not found, ME goes on searching. If then a
permitted operator is found, ME registers to this operator. If no operator is found the ME remains unregistered.
Manual mode: Desired operator can be manually entered, using the AT+COPS write command syntax. If oper-
ator is found, ME registers to this operator immediately. If the selected operator is forbidden, the ME remains
unregistered.
Manual/automatic: In this mode, the ME first tries to find the operator that was manually entered. If the ME fails
to register to this operator, then it starts to select automatically another network.
