According to the CMS error code list at http://support.nowsms.com/discus/messages/1/829.html, this indicates that the provider is purposely rejecting the message.

If this happens with all messages, then perhaps the SIM card is out of credits?

I've also seen where some modems default to expecting to support SMS over GPRS, while some operators do not have this support enabled. So you can try setting "SMS Access" to "GSM" in NowSMS and see if this makes a difference.

This is the support forum for the Now SMS/MMS Gateway product.

If you are experiencing error 21 in your XBox, and you are posting here, then you are lost. This forum has absoutely nothing to do with the XBox.
