WiFi funktioniert nicht

Instead of using your carrier's network connection, you can make voice calls via a Wi-Fi network.  In most ways, it's like any other phone call, and you still use regular phone numbers. diese App calling is especially useful when you're in an area with weak carrier coverage.  Stop wasting your money and time using calling cards for international calls!  That could mean using a Wi-Fi connection you have set up at home, or whatever Wi-Fi hotspot you happen to be on when you're out and about, such as at a cafe or library.  Stop paying for expensive cell minutes and text messages!  For example, when you're traveling to the residential countryside, or you're in a building with spotty reception.  You may already be familiar with using Wi-Fi to send messages when SMS texting is unavailable. -Weekly Subscription for $2. -Monthly Subscription for $8. -Yearly Subscription for $49.
