I'm trying to use this application to send text sms messages to a mobile phone. The mobile phone is a samsung SGH-Z105 and the connection is a Samsung CDMS Modem. I'd like to now if there's any type of special rule that needs to be set for this connection to succeed, cause I can't find out what's the problem. Thanks.

Hi Mariah,

The SGH-Z105 is a WCDMA/UMTS/3G device, right?

We received some feedback from a Samsung test engineer indicating that it appeared to be necessary to manually define the SMSC when submitting an SMS message via the modem interface.

Indeed, "CMS ERROR: 330" indicates that the SMSC address is not known.

I would be curious if you are able to send an SMS message ok using the SMS client in the phone.

Also, I would be curious if it makes any difference if you select "GSM" or "GPRS" for "SMS Access" under the "Properties" for the modem in the "SMSC" list. Although the "GSM" and "GPRS" terminology do not apply to 3G environments, these settings specify whether the modem should use the circuit-switched or packet-switched network, and could make a difference.

If those settings do not make a difference, then I believe that you will need to manually define the SMSC address when using that device as a modem.

This SMSC address varies depending upon what operator you are subscribed to.

You can set the SMSC address by manually editing the SMSGW.INI file. Under the section header for the modem configuration (e.g., [Modem - ...], add SMSC=+phonenumber, where "+phonenumber" is the address of the SMSC. Here's a link to a good list of SMSC phone numbers: A more reliable way of determining the correct SMSC number is to put your SIM into a phone, and go through the SMS configuration menus on the phone to determine the currently configured SMSC number. When you enter the SMSC phone number, always start it with a "+" and don't include any other non-numeric characters (no dashes or dots) in the address.

Always restart the gateway service after making a change to the SMSGW.INI file.

If you try setting the SMSC value by manually editing SMSGW.INI ... if the setting doesn't make a difference, always go back in and remove it immediately so that it doesn't confuse things down the road.
