What is Wifi Calling?

With Wifi Calling, you can make or receive a phone call if you have a Wifi connection in an area with little or no cellular coverage.
Wifi calling is especially useful when roaming internationally. In most cases, carriers will allow you to call any number from your home country as long as you’re on Wi-Fi calling. As this doesn’t add any cost to the carrier and solely depends on your Wifi connection, most carriers will allow you this luxury. The same applies to SMS messages.
If you are traveling abroad it might be a good idea to put your iPhone in airplane mode to ensure that your cellphone doesn’t automatically switch to cellular if the Wifi signal gets bad.
Wifi Calling is currently available on Vodacom, Cell C and Telkom Mobile in South Africa. While MTN did advertise the feature on their website it seems like they never launched the feature and instead rolled out something called MTN Wifi Roaming, which requires the MTN app.

How to enable Wifi calling on your iPhone
