Get access to over1 million WiFi hotspots around the world, and pay on a per minute basis. The app automatically finds hotspots in your local area, if it does not then you can manually go to settings > WiFi and search for supported networks. Payment is through Skype Credit.
When traveling abroad roaming charges can be quite excessive, and paying for WiFi hotspot access abroad can be a hassle and security risk.
Now your same Skype account, credit, and billing info can be accessed and charged from your iPhone/iPod Touch. The pricing starts at $0.06, and can be quite cheap if you only need a few minutes to check e-mail, access a couple of sites, etc. The great thing is that you will be charged only for minute basis and not as per the downloads or uploads done, and one session is chargeable on per 30 minute basis, and disconnects; so there is no unused charges applied.
A very handy app for international travelers. The cost vary differently in every place make sure you check on the charges locally.
