AT+COPS=n,2,m
[M]
Selects the carrier to be
connected.
n=0: Automatic (searches the network and switches the
network operator automatically) (default)
n=1: Manual (connects to the network operator
specified in “m”)
n=2: Disconnects the connection to the network
operator
n=3: Mapping is not performed.
n=4: Manual/Automatic (if the connection to the network
operator specified in “m” fails, works as automatic
mode.)
m: Country code (MCC) and operator code (MNC) are
displayed in a hexadecimal number.
The format is as follows:
Digit 1 of MCC
・・・
octet 1 bits 1 to 4.
Digit 2 of MCC
・・・
octet 1 bits 5 to 8.
Digit 3 of MCC
・・・
octet 2 bits 1 to 4.
Digit 3 of MNC
・・・
octet 2 bits 5 to 8.
Digit 2 of MNC
・・・
octet 3 bits 5 to 8.
Digit 1 of MNC
・・・
octet 3 bits 1 to 4.

m: New PIN1 or PIN2
AT+CPIN?: Displays the state of code entry requested
about current SIM.
Result: +CPIN: <state>
<state>=READY: Code entry not requested
<state>=SIM PIN: PIN1 code entry waited
