3.4.1.2 Check SMS Service Centre number
The SMS are sent by the GE863-QUAD / PY 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
• wait for response in the format:
+CSCA: ,
OK
where:
is the SMSC number
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
response:
+CSCA: +393359609600
OK
3.4.1.3 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=,
where:
is the desired SMSC number
is the SMSC number type:
145 – international numbering scheme (number begins with "+")
129 – national numbering scheme
