Why are some destination numbers accepted and others rejected?

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 would like to set up more destination's on your account, please contact your account manager or use the sales enquiry from on the main website.
