3.5.1.2 Check SMS Service Centre number

The SMS are sent by the GE863-GPS to a service centre (SMSC) where the message is dispatched
towards its final destination or is kept until the delivery is possible. To ensure a correct behavior of this
service the number of the service centre must be the one your network operator supports.
To check which number is stored as the SMSC:

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

TIP: This settings 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's assume you want to check your SMSC number:
command:
AT+CSCA? <cr>
response:
+CSCA: +393359609600

OK

3.5.1.3 Add SMS Service Centre number (only if required)

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.

send command

AT+CSCA=<number>,<type><cr>

where:
<number> is the desired SMSC number
<type> is the SMSC number type:

145 – international numbering scheme (number begins with "+")
129 – national numbering scheme

wait for

OK
