9.13 Service center address +CSCA
Description
This command is used to indicate to which service center the message must be sent.
The product has no default value for this address. If the application tries to send a message without having
indicated the service center address, an error will be generated.
Therefore, the application must indicate the SC address when initializing the SMS. This address is then
permanently valid. The application may change it if necessary.
