What Is Wi-Fi Calling?

Wi-Fi calling is a feature that allows you to make and receive phone calls and send text messages over a Wi-Fi network instead of relying on your carrier’s cellular towers. When you ask “How to Call Wifi Calling?”, you are really asking how to use your phone’s built-in ability to route voice traffic through the internet connection available nearby.

Instead of your phone searching for a strong cellular signal, it connects to a nearby wireless router and sends your voice data as packets over the internet to your carrier’s network, which then connects the call to the recipient. The person you are calling does not need Wi-Fi calling enabled; they simply receive a normal phone call.

This technology is especially helpful in buildings with thick walls, basements, rural areas, and locations where cellular coverage is weak but internet access is strong.

How Does Wi-Fi Calling Work?

When Wi-Fi calling is enabled, your phone constantly monitors both cellular and Wi-Fi signal strength. If the cellular signal drops below a usable threshold but a strong Wi-Fi connection is available, the phone automatically routes the call through Wi-Fi. The handoff is usually seamless, and in many cases you will not even notice the switch.

The process involves your carrier’s IMS (IP Multimedia Subsystem) core, which handles voice over IP traffic. Your phone registers with the carrier over the internet, authenticates your account, and establishes a secure tunnel for voice data. Because the call travels over the internet, call quality depends heavily on your Wi-Fi speed, latency, and router performance.

Most carriers require you to have an active SIM card and an eligible plan. Some also require you to provide an emergency address (E911 address) so that emergency services can locate you when you call 911 over Wi-Fi.

Benefits of Wi-Fi Calling

There are several reasons why millions of users enable Wi-Fi calling on their devices:

• Better coverage indoors: Thick walls and basements often block cellular signals, but Wi-Fi usually penetrates better.
• No extra cost: Most carriers treat Wi-Fi calls the same as regular calls, using your existing plan minutes and data.
• International calling savings: Calling home from abroad over Wi-Fi can avoid expensive roaming charges.
• Seamless handoff: Calls can move between Wi-Fi and cellular without dropping when you leave a building.
• Improved call quality: A strong Wi-Fi connection often delivers clearer audio than a weak cellular signal.
• Text over Wi-Fi: Many carriers also support SMS and MMS over Wi-Fi.

Requirements for Wi-Fi Calling

Before you can use Wi-Fi calling, you need to make sure a few conditions are met:

• A smartphone that supports Wi-Fi calling (most phones made after 2015).
• A carrier that supports the feature on your plan.
• An active SIM card inserted and activated.
• A stable Wi-Fi connection with internet access.
• Updated phone software (latest iOS or Android version recommended).
• An emergency address registered with your carrier (required in many regions).

If any of these are missing, the Wi-Fi calling toggle may not appear in your settings, or calls may fail to connect.

How to Enable Wi-Fi Calling on iPhone

Apple makes enabling Wi-Fi calling straightforward. Follow these steps:

1. Open the Settings app on your iPhone.
2. Scroll down and tap Phone.
3. Tap Wi-Fi Calling.
4. Toggle on Wi-Fi Calling on This iPhone.
5. If prompted, enter or confirm your emergency address.
6. Tap Enable to confirm.

Once enabled, you may also see an option to add Wi-Fi calling for other devices, such as an iPad or Mac, using the same Apple ID. You can enable this if you want to make calls from those devices using your iPhone’s number.

To disable it later, return to the same menu and toggle it off. If the toggle is greyed out, your carrier may not support Wi-Fi calling, or your plan may not include it.

How to Enable Wi-Fi Calling on Android

Android devices vary by manufacturer, but the general process is similar across most phones:

1. Open the Settings app.
2. Tap Network & Internet or Connections (label varies by device).
3. Tap Mobile Network or Call settings.
4. Look for Wi-Fi Calling and tap it.
5. Toggle it On.
6. Confirm your emergency address if asked.

On some Android phones, you can also find Wi-Fi calling inside the Phone app: open the Phone app, tap the three-dot menu, go to Settings, then Calls, then Wi-Fi Calling.

If you cannot find the option, search “Wi-Fi Calling” in the Settings search bar. Carrier-branded phones sometimes place it under a carrier-specific menu.

How to Enable Wi-Fi Calling on Samsung Devices

Samsung Galaxy phones have their own menu layout. Here is how to enable Wi-Fi calling on a Samsung device:

1. Open Settings.
2. Tap Connections.
3. Tap Wi-Fi Calling.
4. Toggle it On.
5. Choose a preference: Wi-Fi preferred or Cellular preferred.
6. Confirm your emergency address.

The “Wi-Fi preferred” option tells your phone to always use Wi-Fi when available, even if cellular signal is strong. “Cellular preferred” uses cellular first and only switches to Wi-Fi when cellular is weak. Choose based on your needs.

How to Make a Wi-Fi Call: Step-by-Step

Now that the feature is enabled, here is exactly how to call using Wi-Fi calling. This is the core answer to “How to Call Wifi Calling?”.

1. Connect your phone to a Wi-Fi network with internet access.
2. Confirm Wi-Fi calling is enabled (see previous sections).
3. Open the Phone app.
4. Enter the number or select a contact.
5. Tap the Call button (green phone icon).
6. Your phone will automatically route the call over Wi-Fi if cellular signal is weak or if Wi-Fi preferred is selected.
7. Speak normally; the call connects just like a regular call.

You do not need to dial any special code or prefix. The phone handles routing automatically. If you want to force Wi-Fi, you can enable airplane mode and then turn Wi-Fi back on; this disables cellular and forces all calls over Wi-Fi. This trick is useful for testing or when you want to avoid roaming charges.

How to Tell If Your Call Is Using Wi-Fi

It is not always obvious whether a call is using Wi-Fi or cellular. Here are ways to check:

• iPhone: Look at the status bar. You may see “Wi-Fi” next to the signal indicator, or “Wi-Fi Calling” in the control center. During a call, the call screen may show “Wi-Fi”.
• Android: The status bar may display a Wi-Fi calling icon (a phone with Wi-Fi waves). Some phones show “Wi-Fi Call” text.
• Samsung: A small Wi-Fi calling icon appears in the status bar during the call.
• Test method: Enable airplane mode, turn on Wi-Fi, and make a call. If it connects, Wi-Fi calling is working.

If none of these indicators appear, your call is likely using cellular. Try toggling Wi-Fi calling off and on, or restart your phone.
