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, or SMS capabilities have not been enabled for the SIM. (Try putting the SIM card into a phone and see if it can send SMS messages.) 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 (under properties of the modem in the "SMSC" list) and see if this makes a difference. -- Des NowSMS Support |
