How to Use WiFi Calling on Your iPhone

Even when you can't get a cell phone signal, you can still make calls and receive texts on your iPhone. With WiFi calling, your calls and texts are routed through whatever WiFi network your iPhone is logged into instead of your carrier's cellular network. That means you can still be reached in the subterranean levels of hospitals, coffee shop dead zones, and anywhere else with good WiFi that you can't get a cellular signal. 

How to activate WiFi calling

WiFi calling is available on iPhone 5c and later models. Your carrier needs to support WiFi calling – all the major carriers do, plus the U.S. carriers on this list.

However, WiFi calling isn’t automatically enabled on iPhones. To turn on WiFi calling, go to the Settings > Cellular > Wi-Fi Calling and then toggle on Wi-Fi Calling on This Phone. You'll be asked to input an Emergency Address to help emergency services respond to your calls. 

Three screenshots of Settings. From the left, the first screenshot shows the main settings menu with Cellular pointed out. The second screenshot shows the main Cellular menu with Wi-Fi Calling pointed out. The third screenshot shows the Wi-Fi Calling page with the option to toggle on Wi-Fi Calling on This iPhone, Update Emergency Address, and Add Wi-Fi Calling For Other Devices.

How to make a WiFi call

Once you activate WiFi calling, you dial or text as usual. The routing of your call or text is handled automatically in the background.

If you make an emergency call, you should always provide your address, especially if you're not at the Emergency Address you provided during setup. You can always edit your Emergency Address by going to Settings > Cellular > Wi-Fi Calling and selecting Update Emergency Address. 

WiFi calling costs 

WiFi calling doesn't cost anything extra, but you may be billed for calls depending on your cellular plan. That's because WiFi calls are treated as if you were placing a cellular call from the U.S. Whatever rates and fees apply to your regular cellular calls will also apply to your WiFi calls, including deducting call minutes from your monthly allotment, if you don't have an unlimited plan, and fees made to international numbers. 

WiFi calling is perfect for overseas travelers because there’s typically no roaming or international charge for making calls or sending texts back home. And many carriers' plans include free calling to Canada and Mexico. Keep in mind, though, that you will be charged an international rate based on your international calling plan if you call an international line using your U.S.-based smartphone. And, WiFi calling isn’t supported in some countries, including China, Cuba, and North Korea.

Check out the WiFi calling pages on your carrier's site for more details. Here are the pages for AT&TT-Mobile, and Verizon

I’ve said it before and I’ll say it again: the ads that pop up right in the middle of your great articles while reading the articles is incredibly annoying!

WiFi calling to the States on my AT&T Phone from overseas.

From Henry Kalir on June 29, 2020 :: 2:53 pm

“WiFi calling is perfect for overseas travelers because there‚Äôs typically no roaming or international charge for making calls or sending texts back home”.

I was banking on this when traveling overseas. BUT - having done it all, I get a “No Network Connection” message, even though the phone is CLEARLY connected to the network, and receives messages without any problems.

Prior to my overseas trip - I was told by ATT to enable Cellular WiFi calling (as you’ve outlined) but keep the phone on Airplane mode, to avoid the international calls.

Any advice would be MUCH appreciated!

Hi Henry,

Which country are you trying to call from? According to AT&T, WiFi Calling is restricted in China, Saudi Arabia, India, Turkey, Israel, United Arab Emirates, Vietnam, Pakistan, Cuba, Iran, North Korea, Sudan, and Syria.

Best,
Josh

Problem solved

Hey Josh,

The solution’s easy: I simply switched to Verizon - at least as far as WiFi calling from Israel goes - there are no restrictions! Works like a charm.

Your phone doesn't need to

From Suzanne Kantra on May 13, 2022 :: 4:49 pm

Your phone doesn’t need to support WiFi calling to use WhatsApp for calls. WhatsApp uses the internet to place and receive calls, so as long as the phone has access to WiFi and can run WhatsApp, you can make calls.

Wifi calling

From Aztecace on May 12, 2022 :: 9:07 am

If you are talking about wifi assisted calls, for when your network isn’t strong enough, I had a problem with it on my previous phone, it was actually worse, than my network, and the calls would drop if I went beyond the wifi rather than switching to my network, which is what wifi assisted should have done. Now using What’s app which is totally wifi is great, chat with my friend when he’s in the UK with very clear calls
