3.5.1.2 Check SMS Service Centre number
The SMS are sent by the GM862-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?<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
