What Is Wi-Fi Calling?

Wi-Fi calling is a feature that lets you make and receive voice calls and text messages over a Wi-Fi network instead of your carrier’s cellular network. The call quality often improves indoors, where cellular signals struggle to penetrate walls. Your phone number stays the same, and the person on the other end does not need any special app.

Technically, Wi-Fi calling uses Voice over IP (VoIP) technology but routes through your carrier’s system, so it counts as a normal carrier call. That means it uses your plan’s minutes and may be billed the same way as a regular call.

Does Samsung S20 Have Wifi Calling?

Yes, the Samsung Galaxy S20, S20+, and S20 Ultra all support Wi-Fi calling. The feature is built into the phone’s firmware and works with most major carriers. However, whether you can actually use it depends on your carrier’s support and your plan.

The Galaxy S20 was released in early 2020 and shipped with Android 10 and One UI 2.1. Wi-Fi calling was already standard on Samsung flagships by then, so the hardware and software are fully capable. You do not need to install a third-party app to use it.

Carrier Support and Compatibility

While the phone supports Wi-Fi calling, your carrier must also support it. In the United States, the major carriers that support Wi-Fi calling on the Galaxy S20 include AT&T, T-Mobile, Verizon, and many MVNOs like Mint Mobile, Google Fi, and Cricket Wireless.

Some regional or prepaid carriers may not support it, or may require a specific plan. Always check with your carrier before assuming the feature will work.

Carrier Compatibility Overview

Carrier Wi-Fi Calling Supported Notes
AT&T Yes Available on most postpaid plans
T-Mobile Yes Widely supported, including prepaid
Verizon Yes Requires compatible plan
Google Fi Yes Automatic on supported devices
Mint Mobile Yes Available on all plans
Cricket Wireless Yes Supported on most plans

Requirements for Wi-Fi Calling

Before you can use Wi-Fi calling on your Galaxy S20, a few conditions must be met. Missing even one can prevent the feature from appearing in settings.

  • A carrier that supports Wi-Fi calling on the Galaxy S20
  • A compatible plan (some prepaid plans exclude it)
  • An active SIM card registered on the network
  • A stable Wi-Fi connection with internet access
  • The latest software updates installed
  • An emergency address registered with your carrier (required by law in the US)

How to Enable Wi-Fi Calling on Samsung S20

Turning on Wi-Fi calling is straightforward. Follow these steps carefully.

  1. Open the Settings app on your Galaxy S20.
  2. Tap Connections.
  3. Tap Wi-Fi Calling.
  4. Toggle the switch to On.
  5. If prompted, enter or confirm your emergency address.
  6. Choose your calling preference: Wi-Fi preferred or Cellular preferred.

If you do not see the Wi-Fi Calling option, your carrier may not support it, or your SIM may not be provisioned correctly. Contact your carrier to confirm.

Enable Wi-Fi Calling via the Phone Dialer

Some carriers also let you toggle Wi-Fi calling through the Phone app. Open the Phone app, tap the three-dot menu, go to Settings, then look for Wi-Fi calling. This is useful if the Connections menu does not show the option.

How to Use Wi-Fi Calling Day to Day

Once enabled, Wi-Fi calling works automatically. When you are connected to Wi-Fi and cellular signal is weak, your phone routes calls over Wi-Fi. You will see a Wi-Fi icon next to the signal bars or a “Wi-Fi calling” indicator in the status bar.

To make a call, just dial as normal. To receive, answer as usual. Text messages also route over Wi-Fi when the feature is active, so SMS and MMS work even with poor cellular coverage.

Important Wi-Fi Calling Settings

The Galaxy S20 offers a few settings worth adjusting.

  • Calling preference: Choose whether to prefer Wi-Fi or cellular when both are available.
  • Wi-Fi calling on other devices: Some carriers allow calls on tablets or watches linked to your number.
  • Emergency address: Keep this updated if you move, since 911 calls route based on it.

Benefits of Wi-Fi Calling on the S20

Wi-Fi calling brings several real-world advantages, especially for people in areas with poor coverage.

  • Better call quality indoors and in basements
  • Ability to make calls where cellular signal is unavailable
  • Seamless handoff between Wi-Fi and cellular in many cases
  • No need for third-party apps like WhatsApp or Skype
  • Text messaging works over Wi-Fi too
  • Can reduce reliance on cellular towers in congested areas

Limitations and Drawbacks

Wi-Fi calling is not perfect. There are situations where it falls short.

  • Requires a stable, fast Wi-Fi connection
  • May not work on all Wi-Fi networks (some block VoIP)
  • Emergency calls may have location accuracy issues
  • International calling rules still apply
  • Some carriers charge for Wi-Fi calls abroad
  • Battery drain can increase on weak Wi-Fi

Troubleshooting Wi-Fi Calling Issues

If Wi-Fi calling is not working on your Galaxy S20, try these steps.

  1. Restart your phone.
  2. Toggle Wi-Fi calling off and back on.
  3. Forget and reconnect to your Wi-Fi network.
  4. Update your phone’s software via Settings > Software update.
  5. Reset network settings (Settings > General management > Reset > Reset network settings).
  6. Contact your carrier to verify provisioning.

If the option is missing entirely, your carrier may not support it, or you may need a carrier update. Some carriers push settings over the air.

Tips and Best Practices

Getting the best experience from Wi-Fi calling on the S20 comes down to a few habits.

  • Keep your emergency address updated, especially after moving.
  • Use a strong Wi-Fi network; weak signals cause dropped calls.
  • Prefer Wi-Fi in known dead zones like basements and rural homes.
  • Disable Wi-Fi calling when traveling internationally if your carrier charges extra.
  • Keep software updated for the latest carrier settings.
  • Test Wi-Fi calling before relying on it in an emergency.
