8.16 AT+CPOL Preferred Operator List
Description: The AT+CPOL read command returns the list of the preferred operators. The AT+CPOL write
command allows to edit the list of the preferred operators. If <index> is given but <operator> is
left out, the entry is deleted.
Syntax: Test Command: AT+CPOL=?

<format>
2 Numeric format
<operator>
Operator in numeric format (GSM Location Area Identification number which consists of a 3-digit country code
plus a 2- or 3-digit network code).
Notes:
• If you enter AT+CPOL=? immediately after the CHV, you get the URC: "+CME ERROR: operation not allowed".
In addition the AT+CPOL command is blocked until the ME is restarted. You get at any time the faulty response:
"+CME ERROR: operation not allowed". The preferred operator list will not be shown.
To avoid this problem and to check the status of SIM initialization after CHV you can activate the "^SIND:
simstatus" URC provided by AT^SIND.
• This command is PIN protected.
• This command is supported in airplane mode.
