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.
- If you see an option for Wi-Fi Calling, tap it and toggle it on.
- If you don’t see the Wi-Fi Calling option in Settings, look for Calls or Calling Accounts and then tap on your SIM card (your carrier name will be next to it).
- 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. If you still can’t find the option, it’s time to check with your carrier and make sure that Wi-Fi calling is enabled on your account.
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.
