How to Enable WiFi Calling on Your iPhone

If you ever find yourself in an area with little to no cellular coverage, you can use WiFi to make and receive phone calls on your iPhone. Plus, all major carriers support WiFi calling for free, so it can also help you save on your monthly cell phone bills. Here’s how to enable WiFi calling on your iPhone and how to use it to make and receive phone calls.

What Is WiFi Calling?

WiFi Calling enables you to make or receive calls over WiFi using your existing device and phone number. This can extend the range of your carrier’s service to rural areas, basements, and anywhere you can get a strong WiFi Signal.

In order to use WiFi calling, you need to be connected to a wireless network with download and upload speeds of at least 2Mbps (megabits per second). To find out if your WiFi connection is strong enough, check out our guide on how to test your WiFi speed.

All major cellular carriers offer WiFi calling for free, as long as you are making and receiving calls and texts from numbers in the US. However, you will be charged if you make or receive calls from international numbers.

WiFi calling generally does not use up your cellular data, but it depends on which carrier you have. If you want to know more about your carrier’s WiFi calling rules, check out the FAQ pages for Verizon, AT&T, and T-Mobile.
