+CPMS - Preferred Message Storage SELINT 0 / 1

<mems> - memory to which received SMs are preferred to be stored

"SM" - SIM SMS memory storage

The command returns the memory storage status in the format:

+CPMS: <usedr>,<totalr>,<usedw>,<totalw>,<useds>,<totals>

where

<usedr> - number of SMs stored into <memr>

<totalr> - max number of SMs that <memr> can contain

<usedw> - number of SMs stored into <memw>

<totalw> max number of SMs that <memw> can contain

<useds> - number of SMs stored into <mems>

<totals> - max number of SMS that <mems> can contain

Note: The only supported memory storage for writing and sending SMs is

the SIM internal memory "SM", so <memw>=<mems>="SM".

Note: the received class 0 SMS are stored in the "ME" memory regardless

the <mems> setting and they are automatically deleted at power off.

Note: If all parameters are omitted the behavior of Set command is the

same as Read command.

AT+CPMS?

Read command reports the message storage status in the format:

+CPMS: <memr>,<usedr>,<totalr>,<memw>,<usedw>,<totalw>,

where <memr>, <memw> and <mems> are the selected storage memories

for reading, writing and storing respectively.

AT+CPMS=?

Test command reports the supported values for parameters <memr>,

Example

AT+CPMS?

+CPMS: "SM",5,10,"SM",5,10,"SM",5,10

OK you have 5 out of 10 SMS SIM positions occupied

Reference GSM 07.05

commands operation mode has been enabled (see #SMSMODE)

(#SMSMODE=0)

AT+CPMS=

<memr>

[,<memw>

Set command selects memory storages <memr>, <memw> and

<mems> to be used for reading, writing, sending and storing SMs.
