With the addition of a new feature allowing your Skype To Go number to be used to make outbound calls from any landline or mobile phone, it just got a lot easier and cheaper to dial internationally. This service also ratchets up Skype's ability to better monetize a massive but largely unpaid user base:

A Skype To Go number lets you make superlow-cost international calls from mobiles and landlines. When you're on the move, dial the Skype To Go number from any phone to reach your friends, family, or business partners abroad. Skype To Go numbers are local numbers, so if they're included in your phone's calling plan, you'll pay only the low Skype rates for the calls you make.
