RUT950 cant send SMS



I am trying to forward sms but get the above error if I try to send.
SIM is fine and valid for sms.


This CMS error indicates that the modem was not able to deliver the message. A few possible causes could be:

  • The mobile plan does not support sending the SMS;

  • The router is not registered on the network;

  • The phone number you are trying to send the message to is invalid or you’re using an incorrect format;

I’d recommend updating to the latest firmware if your device supports it, checking if you can send SMS from your phone using this SIM, setting the device to 3G or 2G-only and checking if the issue reappears, or using a different SIM.

Best regards,
