I cannot get the SMS notification working. When I test the connection, the modem connects to the gateway, then after about 30 secs. there is an error-message:
Result of SMS/Pager notification: Error:  Too many retries. The message was not delivered.
I have tried 2 gateways (Netherlands KPN and Netherlands Libertel) an 2 different modems, in all cases the same message.
Does anyone has any ideas??
