How to Use Wi-Fi Calling on Your Smartphone

Some Android devices, like Samsung phones, have this setting hidden in the Phone app. Here’s how to find it:

Open the Phone app, tap the triple-dot icon at the top right, and tap Settings.
You’ll see an option for Wi-Fi Calling. Tap it and toggle it on.
When it is available, you will see Wi-Fi Calling next to your carrier’s name in the expanded notification shade on your phone.

Can’t find the option on your Android phone? You need a SIM card in your device for the option to even show up (once you pop one in, you might need to restart your phone). If you already have a SIM, open Settings and type “Wi-Fi calling” in the search bar at the top.

What You Need to Know About Wi-Fi Calling

Wi-Fi calls are typically included in your existing voice calls plan and count as regular calls. If you have limited minutes, Wi-Fi calls will likely count as a part of your allowance. They should not incur additional charges, but we recommend you double-check as carriers don’t always treat them the same. If your provider does charge for Wi-Fi calling, then it’s time to find a better carrier.

One thing to note is that any long-distance or international charges you incur for voice calls are likely to apply to Wi-Fi calls as well. And Wi-Fi calling is not supported in every country. As an alternative, try using the call (voice or video) function in internet-protocol messaging apps, such as WhatsApp, Google Duo, Telegram, Signal, WeChat, and FaceTime. You won’t incur charges.

Carriers dictate precisely when your phone should switch to Wi-Fi calling, but this isn’t very consistent. If you find that your signal is just strong enough that Wi-Fi calling doesn’t kick in but it’s not good enough for clear calls, you can force it by turning Airplane Mode on and then toggling Wi-Fi back on. Just remember to turn Airplane Mode off again after the call.
