Introduction

If you have ever wondered How Do You Make Phone Calls Using Wifi?, you are not alone. Millions of people around the world struggle with poor cellular reception indoors, spotty coverage in rural areas, or expensive international roaming charges. WiFi calling solves all of these problems by letting you place and receive voice calls over a wireless internet connection instead of a traditional cellular network.

This guide walks you through everything you need to know — from understanding what WiFi calling is, to enabling it on your iPhone or Android device, to using third-party apps when your carrier does not support the feature. Whether you are a complete beginner or just looking for a refresher, you will find clear, step-by-step instructions here.

What Is WiFi Calling?

WiFi calling is a feature that allows you to place and receive phone calls over a WiFi network instead of using your carrier’s cellular towers. When enabled, your phone routes voice traffic through the internet connection provided by your WiFi router. To the person on the other end, the call looks and sounds like a normal phone call — they do not need any special app or equipment.

Most modern smartphones support WiFi calling out of the box. The feature is typically built into the phone’s dialer and uses the same phone number you already have. There is no need to download anything extra in most cases, although some carriers require you to activate the feature first.

WiFi calling uses a technology called Voice over WiFi (VoWiFi), which is different from Voice over IP (VoIP) apps like WhatsApp or Skype. With carrier WiFi calling, your regular phone number is used, and calls to other phone numbers count against your plan just like normal cellular calls.

Why Make Phone Calls Using WiFi?

There are several compelling reasons to use WiFi calling:

  • Poor cellular signal indoors: Thick walls, basements, and rural locations often block cellular signals. WiFi calling gives you clear audio anywhere you have internet.
  • International travel: Avoid expensive roaming charges by connecting to hotel or cafe WiFi and calling home using your normal number.
  • Better call quality: A strong WiFi connection often delivers clearer audio than a weak cellular signal.
  • Battery savings: Searching for a cellular signal drains battery. WiFi calling reduces this drain significantly.
  • Seamless handoff: Many phones automatically switch between WiFi and cellular mid-call without dropping the connection.

How Do You Make Phone Calls Using Wifi? — Quick Overview

If you want the short answer to How Do You Make Phone Calls Using Wifi?, here it is in four steps:

  1. Connect your phone to a WiFi network.
  2. Enable WiFi calling in your phone’s settings.
  3. Confirm your emergency address (required by most carriers).
  4. Dial a number or receive a call as you normally would.

That is the entire process. The rest of this article breaks each step down in detail for different devices and platforms.

Requirements for WiFi Calling

Before you start, make sure you meet these requirements:

  • A smartphone that supports WiFi calling (most phones from 2015 onward).
  • A carrier that offers WiFi calling (check your carrier’s website).
  • An active WiFi connection with internet access.
  • A SIM card or eSIM from a supported carrier.
  • Your account must be in good standing with the carrier.

If your carrier does not support WiFi calling, do not worry — third-party apps like WhatsApp, Skype, Google Voice, and others can still let you make voice calls over WiFi using a different number or account.

How to Enable WiFi Calling on iPhone

Apple makes enabling WiFi calling on iPhone very 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. A popup will appear asking you to confirm your emergency address. Tap Enable and enter your address.
  6. Wait a few seconds for the feature to activate. You will see “Wi-Fi” next to your carrier name in the status bar.

Once enabled, your iPhone will automatically use WiFi calling whenever cellular signal is weak and a WiFi network is available. You can also choose to prefer WiFi over cellular in the same settings menu.

Prefer WiFi Over Cellular on iPhone

If you want your iPhone to always try WiFi first, go to Settings > Phone > Wi-Fi Calling and enable Prefer Wi-Fi While Roaming. This is especially useful when traveling internationally.

How to Enable WiFi Calling on Android

Android phones vary by manufacturer, but the general process is similar. Here are instructions for the most common setups:

Google Pixel and Stock Android

  1. Open Settings.
  2. Tap Network & Internet.
  3. Tap SIMs (or Mobile Network).
  4. Select your SIM card.
  5. Tap Wi-Fi Calling and toggle it on.
  6. Confirm your emergency address if prompted.

Samsung Galaxy

  1. Open Settings.
  2. Tap Connections.
  3. Tap Wi-Fi Calling.
  4. Toggle it on.
  5. Choose whether to prefer WiFi or cellular when both are available.

OnePlus and Other Brands

On OnePlus, go to Settings > Wi-Fi & Network > SIM & Network > Wi-Fi Calling. The path may differ slightly, but searching “WiFi calling” in the Settings search bar usually finds it quickly.

How to Make WiFi Calls on a Windows PC

You can also make phone calls using WiFi from a Windows computer, which is handy for work or when your phone is charging. Here are the main methods:

  • Phone Link (Windows 11): Connect your Android phone to your PC via the Phone Link app. Once paired, you can make and receive calls directly from your computer over WiFi.
  • FaceTime on Windows: Apple now allows FaceTime calls in a browser, but this requires an Apple device to initiate.
  • Skype, Zoom, or Teams: These apps let you call phone numbers (sometimes for a fee) over WiFi.
  • Google Voice: Free calls to US and Canada numbers from your browser.

Using Third-Party Apps for WiFi Calls

If your carrier does not support built-in WiFi calling, third-party apps are an excellent alternative. These apps use your internet connection to transmit voice data. Popular options include:

  • WhatsApp: Free voice and video calls to other WhatsApp users worldwide.
  • Skype: Free Skype-to-Skype calls; paid Skype Credit for calling regular phone numbers.
  • Google Voice: Free US phone number with free calls to US and Canada.
  • Telegram: Free voice calls with end-to-end encryption.
  • FaceTime Audio: Free high-quality audio calls between Apple devices.
  • Viber: Free calls to other Viber users; paid Viber Out for landlines.

The main limitation of these apps is that both parties usually need the same app installed, unless you pay for outbound calling to regular phone numbers.

Built-in WiFi Calling vs Third-Party Apps

Here is a comparison to help you decide which approach suits you best:

Feature Built-in WiFi Calling Third-Party Apps
Uses your phone number Yes Sometimes (Google Voice gives a new number)
Works with any phone number Yes Only if app supports outbound calling
Requires same app on both ends No Usually yes for free calls
Emergency (911) calling Yes (with registered address) Limited or no
Cost Included in your plan Free to paid depending on app
Call quality Excellent on good WiFi Excellent on good WiFi
Carrier support needed Yes No

Step-by-Step: Making Your First WiFi Call

Now that everything is set up, here is how to actually place a call:

  1. Connect to a stable WiFi network.
  2. Open your phone’s dialer app.
  3. Enter the phone number you want to call.
  4. Tap the call button.
  5. Look for a WiFi icon or “Wi-Fi Call” indicator during the call.
  6. Speak normally — the call routes over WiFi automatically.

If WiFi calling is active, you will usually see a small WiFi symbol next to your carrier name at the top of the screen. If you see only cellular bars, WiFi calling may not be enabled or the WiFi signal may be too weak.

Troubleshooting WiFi Calling Issues

Even with everything set up, you might run into problems. Here are common issues and fixes:

  • WiFi calling not showing up in settings: Your carrier may not support it, or your SIM may need updating. Contact your carrier.
  • Calls dropping: Weak WiFi signal is the usual culprit. Move closer to the router or restart it.
  • Poor audio quality: Too many devices on the network can cause congestion. Disconnect unused devices.
  • Cannot make emergency calls: Ensure your emergency address is registered and up to date.
  • Feature turns off by itself: Some phones disable WiFi calling when battery saver mode is on. Disable battery saver.
  • International calls failing: Some carriers block international WiFi calling. Check your plan.

Tips and Best Practices

To get the most out of WiFi calling, keep these tips in mind:

  • Use a 5 GHz WiFi band if your router supports it — it offers less interference than 2.4 GHz.
  • Register an accurate emergency address — this is critical for 911 calls.
  • Keep your phone’s software updated — updates often improve WiFi calling stability.
  • Test before you travel — make a test call before relying on WiFi calling abroad.
  • Use a VPN cautiously — some VPNs interfere with WiFi calling routing.
  • Restart your phone after enabling WiFi calling for the first time.

WiFi Calling vs VoIP: What Is the Difference?

People often confuse WiFi calling with VoIP. While both use the internet to transmit voice, there are key differences:

  • WiFi calling uses your carrier’s infrastructure and your existing phone number. It is essentially a cellular call that happens to travel over WiFi.
  • VoIP (Voice over Internet Protocol) is a broader category that includes apps like Skype, WhatsApp, and business phone systems. VoIP may use a separate number or account.

In short, all WiFi calling is VoIP, but not all VoIP is WiFi calling. Carrier WiFi calling integrates seamlessly with your normal phone experience, while VoIP apps require both parties to use the same platform (in most free cases).

Security and Privacy Considerations

WiFi calling is generally secure, but keep these points in mind:

  • Calls are encrypted between your phone and your carrier’s network.
  • Public WiFi networks (airports, cafes) can be less secure — consider using a trusted network.
  • Your carrier can still see call metadata (who you called and for how long).
  • Emergency address data is stored by your carrier — keep it updated if you move.
  • Avoid making sensitive calls on unsecured public WiFi without a VPN.

Frequently Asked Questions

Does WiFi calling cost extra?

In most cases, no. WiFi calling is included in your carrier plan and counts against your normal minutes or is unlimited depending on your plan. International calls may still incur charges.

Can I call 911 using WiFi calling?

Yes, but you must register an emergency address. Without it, emergency services may not be able to locate you. Always keep your address updated.

Does WiFi calling work without a SIM card?

Carrier WiFi calling requires a SIM or eSIM. However, apps like WhatsApp or Skype work over WiFi without any SIM card.

Does WiFi calling drain battery faster?

Actually, it usually saves battery compared to searching for a weak cellular signal. The WiFi radio uses less power in most cases.

Can I use WiFi calling on airplane mode?

Yes — you can enable WiFi while in airplane mode and make WiFi calls. This is a great way to call home during flights with in-flight WiFi.

Is WiFi call quality better than cellular?

On a strong, uncongested WiFi network, yes. On a weak or congested network, cellular may be better. The phone usually picks the best option automatically.

Conclusion

So, How Do You Make Phone Calls Using Wifi? The answer is simpler than you might think: connect to WiFi, enable the feature in your phone’s settings, register your emergency address, and start calling. Whether you use built-in carrier WiFi calling or a third-party app, the result is the same — clear, reliable voice calls over your internet connection.

WiFi calling is a game-changer for anyone with poor cellular reception, frequent travelers, and people living in areas with weak signal.
