> Note

> • | 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.
