I'm attempting to test sending an SMS message using a Motorola v3682 (GSM 1900MHz). Current service is through Cingular. I can send and receive SMS messages to/from phone, but keep receiving the following message: ERROR - Modem Response (2): +CMS ERROR: 303.

Any suggestions?

Hi Eric,

You also contacted me via e-mail, so let's follow-up with the dialog there.

The "CMS ERROR: 303" being returned by the phone indicates that the operation is not supported ... which doesn't really make sense. My best guess is that your phone requires the SMSC to be explicitly set when sending out SMS messages, so I'm sending you instructions on how to do that.

If that's not it, we'll do more investigating.
