How to Turn On Wi-Fi Calling on Android

Carrier Wi-Fi calling, sometimes labeled VoWiFi, takes your normal phone number and sends the call over the internet through your Wi-Fi network. The person you call sees your usual number. They do not need any special app, and neither do you. To them it is an ordinary call.

This is different from calling through an app like WhatsApp, Signal, or Google Meet. Those route audio over data too, but they only connect to other people running the same app, and they use a separate account instead of your phone number. Carrier Wi-Fi calling is the one that lets you dial any number, including a landline, and reach 911, all from your real line.

It is also not the same as VoLTE. VoLTE keeps calls on the 4G or 5G network for clearer audio. Wi-Fi calling kicks in when there is no usable cellular signal at all but you do have Wi-Fi. Most modern plans bundle both, and your phone hands off between them automatically.

On a Pixel, open Settings, tap Network & internet, then SIMs. Tap the carrier SIM you want (more on that below if you run two), then tap Wi-Fi calling and switch it on.

There is a second route that flips the exact same setting. Open the Phone app, tap the three-dot menu, go to Settings, then Calls, and you will find the Wi-Fi calling toggle there as well. Either path works; use whichever you remember.

Once it is on, you will usually see a small Wi-Fi calling badge or your carrier's name with a Wi-Fi marker in the status bar when an active call is going over Wi-Fi. That badge is your confirmation it is really working.

Samsung puts the switch in a different place. Open Settings, tap Connections, then tap Wi-Fi Calling and turn it on. On some Galaxy models you will also find a Wi-Fi Calling toggle inside the Phone app under its own Settings, and again it controls the same feature.

One thing worth knowing on recent Galaxy phones like the S24 and S25: when you run two lines, Samsung does not always make it obvious which line is using Wi-Fi Calling. If you toggle it and the wrong number ends up routing over Wi-Fi, open the Wi-Fi Calling screen and check the per-SIM settings there before assuming it is broken.

The first time you switch Wi-Fi calling on, your phone asks for an emergency address. This is not optional paperwork. When you dial 911 over Wi-Fi, the network has no cell tower to estimate your location from, so it sends responders to the address you registered. Enter your full street address, not just a postal code. A zip code alone will not route an emergency call correctly.

If you move, or you regularly use Wi-Fi calling somewhere other than home, go back into the Wi-Fi Calling settings and update that address. On Samsung there is an Emergency Address entry right on the Wi-Fi Calling screen. This is genuinely the most important part of the whole setup, so do not breeze past it.

If you run a dual-SIM or dual-eSIM phone, Wi-Fi calling is a per-line setting. Turning it on for your personal number does nothing for your work number. You have to enable it for each SIM on its own.

On a Pixel, that means going back into Settings > Network & internet > SIMs, picking the other SIM, and flipping its Wi-Fi calling toggle too. If you only set up one and wonder why work calls still drop in the basement, this is almost always why. While you are in the dual-SIM settings, it is worth glancing at which line is set as default for calls so you know which number you are dialing out on.

Here is the honest limit. The Wi-Fi calling switch only appears when your carrier has provisioned the feature for your line and your exact phone model. If you do not see it at all, or it shows but stays greyed out, that is not a bug in Android. It usually means one of these:

• Your carrier has not enabled Wi-Fi calling on your account, or your plan does not include it.
• The carrier has not approved your specific phone variant for the feature (common with phones bought unlocked or imported from another region).
• Your line is not provisioned on the carrier's IMS system, the backend that powers both Wi-Fi calling and VoLTE.

Before you give up, try the usual reset moves: install any pending Android and carrier-settings updates, restart the phone, flip airplane mode on and off, and re-seat the SIM or re-download the eSIM. If the toggle still will not appear, the fix is on the carrier's side. Call them and ask them to enable Wi-Fi calling for your number and confirm your device is on their supported list. There is nothing you can change in Settings that overrides carrier provisioning.

Wi-Fi calling is only as steady as the network behind it. On a weak or congested Wi-Fi connection, calls can sound choppy or drop, sometimes worse than a faint cellular signal. If quality is poor, move closer to the router or test on a different network.

Some carriers let you choose a preference for which network wins when both Wi-Fi and cellular are available. If your phone keeps clinging to a one-bar cell signal instead of switching to solid Wi-Fi, look for a calling-preference option on the same Wi-Fi calling screen and set it to prefer Wi-Fi.

If you are reading this because calls keep failing in general, it is worth ruling out other causes too. Our guide on how to stop spam calls and texts on Android covers settings that can silence or misroute legitimate calls, and once your calls run reliably over Wi-Fi you may still want to block unwanted callers.
