Skype users do not have to pay for Skype-to-Skype video or voice calls, instant messaging, file sharing or the software itself; however, phone calls to landline and cellphone numbers, text messages to mobile devices and the use of Skype's Wi-Fi service all come with a fee. Users can purchase Skype credit on the company's website or sign up for a subscription.
Prices for phone calls made from the Skype software vary, based on the location of the people calling each other. In addition, Skype charges different per-minute fees based on the location of the person one is calling. Users concerned about their spending can purchase a subscription or buy prepaid Skype minutes.
