This error is thrown when you attempt to perform any action on your account through the API that the account does not support.
The most common cause involves setting an Originator value for messages sent through Evaluation and Premium accounts. The Originator on messages sent through these accounts have to match the account's address. For example, if you have a Premium account on the 60066 shortcode, then the Originator for the message has to be 60066. If you have an Evaluation account with the virtual mobile number 447811112222, then the originator for the message has to be 447811112222.
