How many KB does Skype use?

Answer 1

Here are examples of some typical Skype data usage:

• Skype-to-Skype calls: 50kbps or around 3MB for one minute of calling
• Calls to mobile numbers or landlines: 6-20 kbps or around 1MB for one minute of calling
• Video calls between two mobile phone devices: 500kbps
• Video calls between a mobile phone and a computer: 600kbps

Having a large number of contacts on your Skype account also increases the data usage, as the application has to update more contact information, such as statuses, profiles and mood messages.
