Qontact (Roaming)

Qontact allows you to completely avoid paying roaming fees while overseas for calls and messages to and from back home using your existing mobile number when paired with Qongle. You can call through WiFi or cellular data to any type of phone: landlines, non-smartphones and other smartphones.
Before you travel simply install the app on your iPhone and put your SIM card into Qongle and either a Local SIM (at your destination country), a Global SIM, or a Multi SIM into your iPhone and you’re ready to start saving money. There’s no subscriptions or rental fees just a one-time purchase for the Qongle device.
