As a OneSimCard user this app lets me call back to the US for just 2c min from any country when I have a Wi Fi connection And I don t even need to have my OneSimCard international SIM card installed to do it Calling to other countries is also cheap and usually less than Skype                     Great app for making Wi Fi calls while overseas 1ill8

This is a great app I used it in many countries on wi fi and 3G for incoming and outgoing calls Allows to use the same onesimcard phone number both VoIP or when no data available through roaming This is very unique                     Great app Oldham5

On my iPhone 4S crashes as soon as you start it Deleted and reloaded and crashed again Foes not work     Crashes Zjohnp

It s kind of interesting that some people are complaining that it only works with Wifi hey that s the idea I think but I couldn t even open the App crashes right away         Crashes Leib1

Only works while connected to WiFi Does NOT work on LTE I disabled LTE to see if will work on 3G as advertised but failed to work You will not receive calls on PEN number if not connected to WiFi Long distance voice quality worse as compared to any other VOIP service Wasted money Would give ZERO stars if possible     Horrible Service Gvoice Fan
