I cannot send to some numbers or I get the error Invalid destination or destination not covered. How do I fix this?

This usually occurs when the number is incorrect or invalid (please check this article on International Number Formatting) or if the destination network is not set up on your account.

You can check to see if the destination is available on your account by logging into your customer account from the http://www.cardboardfish.com website, click Services, then select the service username that you are experiencing problems with. The available coverage is listed on that page.

If you believe the destination number is correct and coverage for the network is set up on your account, then please contact support and provide the mobile number along with the network which you believe it belongs to. It is possible that the number uses a new prefix which is not yet listed in our database.

You can contact support by logging into your account on our website and creating a new Support Request from the Support page. Please read the Contacting Support article to learn more.
