• The sale of credits and monthly subscription services is Skype's principal source of revenue. Credits allow Skype users to call others, including landlines, send text messages to anybody in the world, and buy a Skype number to receive calls from anyone in the world on their Skype account.
• Skype also has a service called Skype To Go, which allows users to make low-cost international calls from their mobile phones or landlines. There is no need for an internet connection or a data subscription to use the service. A Skype To Go customer can dial a local number that they purchase to ring out to international connections no matter where they are.
