How to Enable Wi-Fi Calling on iPhone 6s or 6s Plus ➝

Serenity Caldwell, writing for iMore:

Instead of routing your voice packets through your carrier’s closest cell tower, those packets get tunneled through the Internet to a controller used by your cell company, which then bounces them across the network to whomever you’re speaking. The net result is that you’re talking, but you’re not actually using a cell tower to do it.

If your carrier supports Wi-Fi calling, it’s a great way to get clearer, crisper calls when chatting with all your friends—not just those on an iPhone or Mac.
