## Description

This error means the destination mobile operator flagged the SMS as international traffic that was sent through a domestic gateway. The message was misrouted as domestic.

### Possible causes

* The destination mobile operator identified the message as international SMS traffic sent through a domestic gateway.
* The message was routed over a domestic route when the destination required an international route.

### Possible solutions

* Review the SMS Guidelines for the destination country and check for restrictions on domestic or international traffic.
* If the message is genuinely domestic, open a support request and provide evidence to clarify the routing.
* If the message is international, open a support ticket and request that the messages be moved to the appropriate international gateways.
* Make sure your sender has global SMS capability and that international messaging is enabled for the countries you want to reach. ([help.twilio.com](https://help.twilio.com/hc/en-us/articles/223133947-What-is-Global-SMS-and-how-does-it-work))
