+CME ERROR: 547 Emergency call is allowed without SIM
Careful: Error code + CME ERROR: 546 or +CME ERROR: 547 are only returned if SIM is not
present.
The fact that network supports emergency calls (+CME ERROR: 547) does not imply
that emergency calls will work without a SIM. The only way to know it is to try atd112.
Response syntax for AT+COPS?:
+COPS: <mode> [, <format>, <oper> ]
Response syntax for AT+COPS=?:
+COPS: [list of supported (<stat>, long alphanumeric <oper>, short alphanumeric
<oper>s, numeric <oper>) s]
Notes:
‧ If an incoming call occurs during a PLMN list request, the operation is aborted (+CME
ERROR: 520) and the unsolicited RING appears.
‧ If SPN (Service Provider Name) is present in the SIM, it will be returned in both long
and short alphanumeric <oper> fields. The string in the “short” field will be the SPN
truncated to the appropriate character number (10).
The following operations are allowed without a SIM inserted, or PIN activated:
AT+COPS? : get current PLMN
AT+COPS=? : List allowed PLMN
AT+COPS=1,2,<plmn> : Set manually current PLMN.
