 send command AT+CSCA?<cr>
 wait for response in the format: +CSCA: <number>,<type>
OK
where:
<number> is the SMSC number
<type> is the SMSC number type:
145 - international numbering scheme (number begins with "+")
129 - national numbering scheme
This setting remains stored in the SIM card until it is changed or deleted, so this operation
may be done only once if the SIM Card is not changed. The setting is maintained even after
power down.
For example:
1- Let us assume you want to check your SMSC number:
command
AT+CSCA? <cr>
response:
+CSCA: [phone]
OK
If your previously check for SMSC returned an empty field:
+CSCA: ,129
Or if the SMSC number stored does not correspond to the desired one, then the new number
has to be stored. In this way, the previously stored number will be overwritten.

<type> is the SMSC number type:
