The first group of command tells the router to work only with the primary SIM (the one inside the
router). While using:
set backup checking-ipaddr 88.1.1.1 via icmp through-interface ppp0

root@IMOLA>
unlock-sim
AT+CPIN?
+CPIN: READY
OK
Then, the GPRS module can be activated. If the result is:
root@IMOLA>
unlock-sim
AT+CPIN?
+CPIN: PIN
OK
it is necessary to execute the command specifying the PIN as argument:
root@IMOLA> unlock-sim 1234
It is necessary that the modem is operational so that the command can be effective, otherwise the
command will not give any input. In order to have the modem operational, the command
