Syntax:
This command allows the message storage area to be selected (for reading, writing, etc).
<mem1>:
<mem2>:
<mem3>:
If the command is correct, the following message indication is sent:
When <mem1> is selected, all following +CMGL, +CMGR and +CMGD commands are related to the
type of SMS stored in this memory.
The maximum number of SMS is Flash is 99.
When the modem is switched on, <mem1>,<mem2>, and <mem3> are initialized to SM.
