Great app – YouRoam: WiFi phone calls and text messaging Review

Of all I tried this one was the least obtrusive and cheapest to get started, with the safety of Apple in-app-purchase too. Worked straight away and given weak wifi I was using the call quality was great. Highly recommended if you don't have something like this already. Great stuff
