Undocumented gateway response codes
September 9th, 2009
Occasionally the gateway will respond with a response code that is not documented in our site’s Common API responses.
When this happens the response will be coming directly from the mobile network provider rather than generated from our own gateway, as such this is not something that can be documented.
However, these response codes almost always resolve to the phone number you are trying to send an SMS to, check you are using the correct number, and if it is international number, be sure to take a look at the article on International SMS numbers.
As always, if you have any questions please comment below, or register on our forum.
