Note:
This specific command is used to read the EF-CBMI SIM file.
The EF-CBMI file is not used with the +CSCB command.
The application should read this file (using AT+WCBM ?) and combine the Message Identifiers with
those required by the application.
<mids> message identifiers
Command Syntax: AT+WCBM= <mids>
This command allows the manipulation of a message status. The accepted status changes are from
READ to NOT READ and vice versa, and also from SENT to NOT SENT and vice versa.
<loc>
<status> New status to be stored, as in the +CMGL command
Command Syntax: AT+WMSC= <loc>, <status>
Possible responses:
If all parameters are correct, the product overwrites the whole SMS in SIM.
Only the first byte (Status byte) is changed.
