Some Nokia modems (e.g. C6) are able to send SMS messages via AT commands, but not receive or store them.

The Messaging interface could expose a flags property specifying what the modem can do (e.g. Send, Receive, Store).

For the case of the Nokia phones, we could then check whether the phone can:

• Send messages, with e.g.: AT+CMGS=? OK
• Store messages, with e.g.: AT+CMGW=? ERROR
• Receive messages, with e.g.: AT+CNMI=? ERROR AT+CPMS=? +CPMS: (),(),()
