Does what it says I was broke and lost my cell service. So I downloaded a voip app and used WiFi for calling. When out around town I'd connect to various hotspots and make calls. This app kept up with all the WiFi's for me and connected. Some I'd have to open a browser  etc. Yet it saved me a lot of hassles. Now I have cell again and I use it to connect to different WiFi's so I can save on my mobile data. Never a problem. Ran it on three devices including a tablet.
