[Hilo] How to use <AT+CRSM>?

#1

Answer: To know the identifier of an elementary data file on SIM, please refer to “3GPP TS 11.11: Specification of the Subscriber Identity”
For example:
AT+CRSM=176,28539,0,0,12 ==> EFFPLMN (Forbidden PLMNs, Identifier: ‘6F7B’)
+CRSM: 144,0,“64F010 64F040 FFFFFFFFFFFF”
OK
AT+CRSM=176,12258,0,0,10 ==> EFICCID (ICC Identification, Identifier ‘2FE2’)
+CRSM: 144,0,“9868001F912198087937”
OK
