This is how Vyke Mobile works so you can save a lot of money on your next mobile phone bill. When your phone is connected to a WiFi hotspot you are able to send your mobile calls via the Vyke network instead of via your regular operator. As we're connecting your call via the Vyke Network we check to see if the person you're calling is a Vyke user. If they are and they're connected to a WiFi hotspot too then we connect your call for free. If the person you're calling is not a Vyke user or they're not online when you make your call, then we simply connect your call via the regular telephone network instead but at our fantastically low rates.
