Syntax:
Command Syntax: AT+CSMP=<fo>, <vp>, <pid>,<dcs>
This command deletes one or several messages from preferred message storage (“BM” SMS CB ‘RAM
storage’, “SM” SMSPP storage ‘SIM storage’ or “SR” SMS Status-Report storage).
Refer to the Preferred Message Storage +CPMS command.
<index> If <DelFlag>=0
<DelFlag>
If <DelFlag> is omitted, default value is used.
When the preferred message storage is “SR”, as SMS status reports are assumed to have a “READ”
status, if <DelFlag> is greater than 0, all SMS status reports will be deleted.
