Introduction

If you have recently picked up a Samsung Galaxy S25, you might be wondering how to get the best possible call quality inside your home or office. One of the most useful features built into this device is WiFi calling. This guide walks you through How to Enable Wifi Calling on Samsung S25? and explains everything you need to know about the S25 settings that control it.

WiFi calling lets your phone place and receive calls over a wireless internet connection instead of relying solely on a cellular tower. It can be a lifesaver in areas with weak mobile signal, and it often works seamlessly once you flip the right switch. In the sections below, you will find step-by-step instructions, troubleshooting tips, carrier considerations, and answers to common questions about the Samsung S25.

What Is WiFi Calling?

WiFi calling is a feature that routes your voice calls through a WiFi network rather than through your mobile carrier’s cellular network. When you make a call, your Samsung S25 connects to your router, sends the voice data over the internet, and hands it off to the carrier’s core network. The person on the other end receives the call just like any normal phone call, and they do not need any special app or setting.

This technology is especially helpful when cellular reception is poor but you have a strong WiFi signal. Basements, concrete buildings, and rural homes often suffer from spotty coverage. With WiFi calling enabled, your phone can maintain a reliable connection as long as your internet is stable. Most modern carriers support it, and it is usually included in your existing plan at no extra charge.

Why Enable WiFi Calling on Samsung S25?

The Samsung Galaxy S25 is designed with advanced connectivity in mind, but even the best hardware cannot overcome a dead cellular zone. Enabling WiFi calling gives you a backup path for voice communication. Here are a few reasons to turn it on:

  • Improved call quality in low-signal areas.
  • Seamless handoff between WiFi and cellular when you leave the house.
  • No need to install third-party calling apps.
  • Potential savings on international roaming charges, depending on your carrier.
  • Better reliability for important calls when cell towers are congested.

If you are asking How to Enable Wifi Calling on Samsung S25?, the good news is that the process takes only a few minutes once you confirm that your carrier supports the feature.

Prerequisites Before You Begin

Before you dive into the S25 settings, make sure you have the following in place:

  • A Samsung Galaxy S25 connected to a stable WiFi network.
  • A carrier plan that includes WiFi calling support.
  • An active SIM card or eSIM from that carrier.
  • The latest software update installed on your device.
  • Correct emergency address information registered with your carrier.

If any of these items are missing, the WiFi calling option may not appear in your settings, or it may appear grayed out. Contact your carrier if you are unsure whether your line is provisioned for WiFi calling.

How to Enable Wifi Calling on Samsung S25? Step-by-Step

There are more than one way to reach the WiFi calling toggle on the Samsung S25. Below are the most reliable methods.

Method 1: Using the Settings Menu

  1. Unlock your Samsung S25 and open the Settings app.
  2. Scroll down and tap Connections.
  3. Look for WiFi calling and tap it. On some firmware versions, it may be listed under Mobile networks or Call settings.
  4. Toggle the switch to On.
  5. If prompted, read and accept the terms and conditions.
  6. Enter or confirm your emergency address when asked. This helps emergency services locate you if you call 911 over WiFi.
  7. Wait for the confirmation message that WiFi calling is active.

Once enabled, you should see a WiFi calling icon in your status bar during an active call, indicating that the call is routing over your wireless network.

Method 2: Using Quick Settings

  1. Swipe down from the top of the screen to open the Quick Settings panel.
  2. Swipe again to reveal the full set of toggles if necessary.
  3. Look for the WiFi calling tile. If you do not see it, tap the pencil icon or Edit to add it to your panel.
  4. Tap the tile to turn WiFi calling on or off.

This method is convenient for quickly disabling WiFi calling if you are on a limited internet connection or experiencing call drops.

Method 3: Through the Phone App

  1. Open the Phone app.
  2. Tap the three-dot menu in the top-right corner and select Settings.
  3. Look for Calling accounts or WiFi calling.
  4. Select your SIM card and enable the WiFi calling toggle.

Not all carrier versions of the S25 expose WiFi calling inside the Phone app, so if the option is missing here, return to the main Settings menu.

Understanding S25 Settings for WiFi Calling

After enabling the feature, you may want to review how the S25 settings handle WiFi calling preferences. The device typically lets you choose between three connection modes:

  • Prefer WiFi: The phone uses WiFi calling whenever a suitable network is available, even if cellular signal is present.
  • Cellular preferred: The phone uses the cellular network first and falls back to WiFi only when cellular is weak.
  • Never use WiFi: WiFi calling is disabled entirely.

You can adjust these preferences in the same Connections menu where you enabled the feature. Choosing the right mode depends on your environment. If your home WiFi is fast and your cell signal is poor, “Prefer WiFi” usually delivers the most consistent experience.

Carrier Support and Compatibility

WiFi calling is not universal across every carrier and every plan. Major U.S. carriers such as AT&T, T-Mobile, and Verizon generally support WiFi calling on the Samsung S25, but smaller MVNOs may have restrictions. Some prepaid plans exclude the feature entirely.

To confirm compatibility:

  • Log in to your carrier account online and check your line features.
  • Call customer support and ask if WiFi calling is provisioned for your number.
  • Look for the WiFi calling option in your S25 settings. If it is missing, your carrier may not support it on your current plan.

Keep in mind that even if your carrier supports WiFi calling, you may need a specific SIM card or eSIM profile to activate it.

Troubleshooting Common Issues

Sometimes WiFi calling does not work immediately after you enable it. Here are common problems and how to fix them.

WiFi Calling Option Is Missing

If you cannot find the toggle in S25 settings, restart your phone and check for software updates. A carrier settings update may be required. If the option still does not appear, contact your carrier to verify that your account is eligible.

Calls Drop or Sound Choppy

This usually points to a weak WiFi signal or network congestion. Move closer to your router, reduce the number of devices streaming video, or restart your router. You can also switch the S25 setting to “Cellular preferred” if your mobile signal is stronger than your WiFi.

Emergency Address Not Accepted

Carriers require a valid physical address for E911 routing. Make sure you enter a real street address, not a P.O. box. If you move, update this address in your WiFi calling settings right away.

International Calls Fail Over WiFi

Some carriers block international WiFi calling by default. Check your plan details or enable international calling through your carrier’s website or app.

Tips and Best Practices

To get the most out of WiFi calling on your Samsung S25, keep these tips in mind:

  • Use a 5 GHz WiFi band when available for lower latency and clearer voice quality.
  • Keep your phone’s software updated to ensure carrier compatibility.
  • Test WiFi calling with a short call after enabling it to confirm the icon appears in the status bar.
  • Update your emergency address whenever you move or travel for an extended period.
  • If you experience echo or delay, disable Bluetooth headsets temporarily to rule out audio accessory issues.
  • Turn off WiFi calling when using a slow or metered internet connection to conserve bandwidth.

Emergency Calls and Location Services

One important detail about WiFi calling is how emergency services handle your location. When you call 911 over WiFi, the dispatcher may not receive your precise GPS coordinates automatically. Instead, the system uses the emergency address you registered with your carrier.

Always keep this address current. If you are staying at a hotel or a friend’s house, remember that your registered home address may be sent to emergency responders unless you update it. For the best safety, enable location services on your S25 and verify that your carrier has your most recent address on file.

Using WiFi Calling While Traveling Internationally

WiFi calling can be a money-saver when you are abroad. Because the call routes over the internet, some carriers treat it as a domestic call even when you are overseas. However, policies vary widely.

Before you travel:

  • Check whether your carrier allows outbound WiFi calls from foreign countries.
  • Confirm if incoming WiFi calls are free or charged at international rates.
  • Disable cellular data roaming to avoid accidental charges while relying on WiFi.

If your carrier does not support international WiFi calling, consider using a local SIM or eSIM and enabling WiFi calling through that provider instead.

Battery and Data Impact

WiFi calling uses data, though voice calls are relatively lightweight compared to video streaming. A typical voice call might consume roughly 1 MB per minute, depending on the codec your carrier uses. On an unlimited home internet plan, this is negligible. On a mobile hotspot with a data cap, it is worth monitoring.

Battery usage is generally comparable to a regular cellular call. However, if your WiFi signal is weak, the phone may use more power maintaining the connection. In that case, switching to cellular preferred mode can preserve battery life.
