If you make a ton of overseas calls, you may want to look into Skype's relaunched Skype to Go service. Announced today, the revamped service makes it easier for users to call international numbers, and allows them to call from non-internet phones like landlines.
The ease of use comes in the form of direct numbers users can call to reach pre-saved numbers. Before, callers would have ring into a voice menu that would then give them a list of numbers they can call, but now that's no more. Users can program up to nine direct-dial numbers in any of Skype's foreign markets. Ballin' on a budget, this is.
