How can I find the Service Center Address? AT+CSCA does not seem to be supported.

In order to send an SMS in PDU mode, I need a Service Center Address.  Normally, you can find it via AT+CSCA, but this does not seem to be supported on modem firmware v1.0.0.  How can I query the service center address?

Hi Brendan,

You don't need Service Center Address because the SIM normally has the SMSC already defined.
