Maybe this http://www.developershome.com/sms/cpmsCommand.asp[^] might help you a bit.

My guess is, that the modem wants to tell you that there are no messages stored in any place. What is the answer when you send a SMS to the phone number of the modem?

Did you try to set the storage place?

And: Did you insert a sim card?
