How does WiFi calling work?

your calls and texts are routed through whatever WiFi network your iPhone is logged into instead of your carrier's cellular network.


Once you activate WiFi calling, you dial or text as usual. The routing of your call or text is handled automatically in the background. No separate app or log-in or number is needed.

WiFi calling is perfect for overseas travelers because there’s typically no roaming or international charge for making calls or sending texts back home.

Moreover, you can use your iPhone mobile account to make and receive calls on devices signed into your iCloud account when they are nearby and on Wi-Fi. Just make sure you have the Calls on Other Devices option enabled under the Calls section of Phone settings.

What does WiFi calling mean?

In layman terms, Wi-Fi calling means making phone calls using a wireless Internet connection instead of routing them through the supported carrier at locations where cellular coverage is either limited or unavailable. The technology not only helps in maintaining the overall call quality, but also extend the phone’s battery life, as weak cell signals force your phone to use more power to boost the connection. In all, it optimizes both, the battery life and the user experience.

Does WiFi calling use data?

Yes, but calls made using Wi-Fi calling technology use up very little bandwidth, so much that, you may not even realize it even if you are on a lower-speed broadband network or one that has usage caps.  A 5 minutes call consumes less than 5 MB data.

Hope that makes sense!
