The White Calling app offers the lowest international call rates and allows users to send mobile airtime top-up to recharge mobiles back home. The app provides great call quality and reliability by calling real phone numbers instead of app-to-app. It is also very easy to use and offers free credit when you install the app, as well as additional free credit when you invite friends to join. With the White Calling app, users can stay connected with friends and loved ones around the world, as there is no need for the other person to have the app to receive a call.

In addition to making international calls, the White Calling app also allows users to recharge the mobiles of their friends and family all over the world. The top-up is sent and loaded instantly, and the app offers great rates and reliability for this service.

The White Calling app provides three ways to make calls. Users can let the app call via a local access number, which automatically routes the call to the international number for the best call quality and reliability. This option is available in select countries. Users can also make calls over Wi-Fi, which is ideal for those on Pay As You Go or with poor phone reception, as well as for travelers. Alternatively, users can make calls over 3G/4G, which is great for those with a large monthly data allowance. Existing White Calling card customers can also add their card PIN in the app and use their existing balance.
