If I want to use the Skype app for my Wind Nokia 500 AT MY HOME aka my internet connection/wifi - will that be free?
Wi-Fi is a local wireless network. Since Wi-Fi is independent of your plan data any Skype calls or other internet activities made over a Wi-Fi connected network will not count to your total/monthly "data usage".
So if your phone displays the Wi-Fi icon ") ) )" then you can talk all you want over Skype and not care about your mobile data.
Hope this was helpful.
Cheers.
Yes, it'll be free to access Skype on your phone as long as you use your Wi-Fi connection.
