All Non-Enterprise accounts cannot place international calls. An International Calling Plan is required (and this is only available for Enterprise accounts).
As a member of a Sideline Enterprise account, you have the option to place unlimited international calls if you subscribe to the international calling plan.
We support calls to over 165 countries, providing you the opportunity to keep in touch with people all over the globe for only $14.99/month. Click here to view the International Calling List.
