The app offers simplified access to over a million public WiFi hotspot around the world. You have to pay several cents per minute but you are online within a few taps. Skype WiFi (iPhone & iPad) uses your Skype account and Skype credit to go online. No need to register with each hotspot provider at airports, hotels, etc. and give them your credit card details. To use the service, click on a supported hotspot network and connect, make sure you have enough Skype credit! After 30 minutes auto disconnect kicks in but you can reconnect. If you want to stop surfing before the 30 minutes are up, you do that manually. Unfortunately not every WiFi provider is supported by the free app.
