What Is WiFi Calling?

WiFi calling, sometimes referred to as VoWiFi (Voice over WiFi), is a technology that lets your smartphone route voice calls through a WiFi network rather than through a traditional cellular tower. When you make a WiFi call, your voice is converted into data packets and sent over your internet connection to your carrier’s network, which then connects the call to the recipient—whether they are on a mobile phone or a landline.

From the user’s perspective, WiFi calling feels almost identical to a regular phone call. You use the same dialer app, your contacts list remains the same, and the person on the other end does not need any special app or setting to receive your call. The main difference happens behind the scenes: instead of searching for the strongest cell signal, your phone connects to an available WiFi network and uses that as the bridge for your voice data.

This feature is especially useful in several common scenarios:

  • Your home or office has thick walls that block cellular signals but has strong WiFi.
  • You are in a basement, rural area, or building with poor mobile reception.
  • You are traveling internationally and want to avoid roaming charges by calling home over WiFi.
  • Your cellular network is congested during an event or emergency, but local WiFi remains available.

To use WiFi calling, three things generally need to be true: your device must support the feature, your carrier must offer it for your plan, and you must be connected to a WiFi network that allows voice traffic. The Samsung S25 checks the first box, as we will discuss next.

Does Samsung S25 Have Wifi Calling?

If you are asking Does Samsung S25 Have Wifi Calling?, the answer is a clear yes. Samsung’s Galaxy S25 series—including the standard S25, the S25+, and the S25 Ultra—comes with built-in support for WiFi calling. The feature is integrated directly into the phone’s native dialer and settings, so you do not need to download a third-party app to use it.

Samsung has included WiFi calling on its flagship Galaxy devices for several generations, and the S25 continues that tradition. Because the S25 is designed as a premium device with modern connectivity standards, it includes the necessary hardware and software to handle VoWiFi seamlessly. When the feature is active, you may see a small indicator in your status bar or notification panel showing that calls are being routed over WiFi.

It is important to note, however, that having the hardware capability is only half the equation. Whether you can actually turn on and use WiFi calling depends heavily on your mobile carrier. Some carriers enable the feature by default for all compatible devices, while others require you to activate it on your account or subscribe to a specific plan. In the next section, we will look at how carrier support factors into the experience.

If you recently purchased a Samsung S25 and do not see the WiFi calling option immediately, do not assume the phone lacks the feature. It is more likely that the setting is hidden because your carrier has not provisioned it for your line, or because your phone needs a software update. We will cover how to check for and resolve that later in this guide.

Samsung S25 Specifications Overview

To understand why the Samsung S25 handles WiFi calling so well, it helps to look at its connectivity specifications. While Samsung refines its flagship lineup each year, the S25 series is built with modern wireless standards that make internet-based calling stable and high-quality.

The device supports advanced WiFi protocols, including dual-band WiFi with compatibility for both 2.4 GHz and 5 GHz networks. Newer models in the S series also support WiFi 6E or WiFi 7 depending on the region and variant, which means faster data throughput and lower latency. For WiFi calling, low latency is critical because it reduces echo, delay, and choppy audio.

Beyond WiFi, the S25 includes 5G and LTE connectivity, Bluetooth for accessories, and NFC for contactless payments. These radios work together so that your phone can hand off a call between cellular and WiFi without dropping the connection. For example, if you start a call on WiFi at home and then walk out the door, the phone can transition the call to the cellular network seamlessly—provided both networks are available and your carrier supports the handoff.

From a software perspective, the S25 runs Samsung’s One UI over Android. The Phone app includes a dedicated menu for WiFi calling preferences, emergency address registration, and network selection. This deep integration means you do not need to hunt through obscure menus to manage the feature.

Carrier Support for WiFi Calling on Samsung S25

Even though the Samsung S25 has WiFi calling capability, you cannot use it unless your wireless carrier supports the feature on your specific plan. Carrier support varies by country, by network, and sometimes even by the individual price tier you pay for.

In the United States, the major carriers—AT&T, T-Mobile, and Verizon—all offer WiFi calling on compatible Samsung flagship devices. Generally, you need a postpaid account with HD Voice or VoLTE enabled. Prepaid plans may or may not include the feature depending on the carrier’s policies. Smaller MVNOs that operate on these networks sometimes support WiFi calling, but not always, so it is worth checking with your provider.

Internationally, carriers in the United Kingdom, Canada, Australia, and across Europe commonly offer WiFi calling on Samsung Galaxy devices. Again, activation may require you to toggle a setting in your online carrier account or contact customer service.

Here are a few general requirements that most carriers share before enabling WiFi calling on a Samsung S25:

  • A compatible Samsung device (the S25 qualifies).
  • An active SIM card or eSIM from the carrier.
  • HD Voice or VoLTE enabled on your line.
  • A registered emergency address, since WiFi calls do not always transmit location data to emergency services automatically.
  • A WiFi connection that meets minimum speed and stability thresholds.

If you are unsure whether your plan includes WiFi calling, the easiest way to check is to look in your Samsung S25 settings. If the option is missing or grayed out, your carrier likely has not enabled it for your account.

How to Enable WiFi Calling on Samsung S25

Enabling WiFi calling on the Samsung S25 is straightforward, provided your carrier supports the feature. Follow these steps to turn it on and verify that it is working.

Step 1: Open the Settings App

From your home screen or app drawer, tap the Settings icon. You can also swipe down from the top of the screen and tap the gear-shaped Settings icon in the quick settings panel.

Step 2: Go to Connections

In the Settings menu, select “Connections.” This section manages your WiFi, Bluetooth, mobile networks, and calling features.

Step 3: Find WiFi Calling

Look for an option labeled “WiFi calling” or “Wi-Fi Calling.” On some One UI versions, it may appear under “Mobile networks” or “More connection settings.” Tap on it to enter the WiFi calling menu.

Step 4: Toggle the Switch to On

You should see a toggle switch. Tap it to turn WiFi calling on. If the switch is grayed out or missing, your carrier may not support the feature on your current plan, or your phone may need a carrier settings update.

Step 5: Register Your Emergency Address

When you enable WiFi calling for the first time, Samsung and your carrier will ask you to register an emergency address. This is critical because when you call emergency services over WiFi, the dispatcher needs a physical location to send help. Enter your home or primary address carefully and confirm it.

Step 6: Verify Activation

After enabling the feature, look at your status bar. You may see a WiFi calling icon, or the text “WiFi calling” may appear when you open the dialer. You can also place a test call to a friend or family member to confirm the audio is clear and the connection is stable.

If you ever want to disable the feature, simply return to the same menu and toggle the switch off.

How to Make a WiFi Call on Samsung S25

Once WiFi calling is enabled, making a call works exactly like making a regular cellular call. Open the Phone app, dial the number, and press the call button. Your Samsung S25 will automatically route the call over WiFi if you are connected to a qualifying network and cellular signal is weak or unavailable.

You do not need to dial a special prefix or use a separate app. The recipient sees your regular phone number on their caller ID, and they can answer using any phone. If you move out of WiFi range during a call and your carrier supports network handoff, the call may switch over to LTE or 5G without dropping.

To confirm a call is using WiFi calling, watch for visual indicators. Some Samsung devices display a small phone handset icon with a WiFi symbol, or the status bar may show “WiFi calling” near the signal indicators. If you are unsure, you can check the call details after the call ends in your recent calls log.

WiFi Calling vs. Regular Cellular Calling

It is helpful to understand how WiFi calling compares to traditional cellular calling so you know when to rely on each method. The table below outlines the key differences.

Feature WiFi Calling Regular Cellular Calling
Network used Wireless internet (WiFi) Cellular tower (LTE/5G/3G)
Signal requirement Stable WiFi connection Cellular coverage
Caller ID Your regular mobile number Your regular mobile number
Special app needed No No
International use Often avoids roaming fees (carrier-dependent) May incur roaming charges abroad
Emergency calls Supported, but requires registered address Supported with automatic location
Battery impact Can save battery in weak cellular areas Can drain battery when searching for signal
Data usage Uses minimal WiFi data Uses cellular voice channels, not data plan

As the table shows, neither option is universally better. WiFi calling excels when cellular reception is poor but internet is strong. Regular cellular calling remains the default when you are out and about with good tower coverage.

Troubleshooting WiFi Calling on Samsung S25

Even on a capable device like the Samsung S25, WiFi calling can occasionally act up. Below are the most common issues and how to fix them.

WiFi Calling Option Is Missing or Grayed Out

If you do not see the WiFi calling toggle, first confirm that your carrier supports the feature on your plan. Next, check for software updates by going to Settings > Software update > Download and install. Carrier settings updates often arrive through system updates and can unlock the option.

Calls Dropping or Poor Audio Quality

Poor WiFi calling quality is usually caused by a weak or congested wireless network. Try moving closer to your router, switching to the 5 GHz band if your router supports it, or restarting the router. You can also enable Airplane mode for a few seconds and then turn WiFi back on to force a fresh connection.

Emergency Address Not Accepted

Carriers require a valid physical address for emergency routing. If your address is rejected, double-check the spelling and formatting. Use the address where you most often use WiFi calling, such as your home or office.

Call Will Not Switch Between WiFi and Cellular

Seamless handoff between WiFi and cellular depends on carrier support and signal strength. If the call drops when you leave WiFi range, your carrier may not support the handoff feature, or the cellular signal may be too weak to pick up the call in time.

General Fixes to Try

  • Restart your Samsung S25.
  • Toggle WiFi calling off and back on in settings.
  • Reset network settings (Settings > General management > Reset > Reset network settings). Note that this will erase saved WiFi passwords.
  • Contact your carrier to confirm your account is provisioned for WiFi calling.

Tips and Best Practices for WiFi Calling

To get the most reliable experience from WiFi calling on your Samsung S25, keep these best practices in mind.

  • Use a strong WiFi signal: The closer you are to your router, the better your call quality will be. Avoid making WiFi calls from the edge of your network’s range.
  • Prefer the 5 GHz band: If your router broadcasts both 2.4 GHz and 5 GHz networks, connect your phone to the 5 GHz band for less interference and lower latency.
  • Keep your software updated: Samsung regularly releases One UI updates that improve call stability, battery management, and carrier compatibility.
  • Enable HD Voice and VoLTE: These features often work alongside WiFi calling to provide clearer audio and smoother network transitions.
  • Keep your emergency address current: If you move, update your emergency address in the WiFi calling settings immediately.
  • Test before you travel: If you plan to rely on WiFi calling abroad, test it at home first and confirm with your carrier that international WiFi calling is included in your plan.
  • Use WiFi calling in weak cellular areas: If your office or basement has no cell bars but good WiFi, make WiFi calling your default to save battery and avoid dropped calls.

International Roaming and WiFi Calling

One of the most practical benefits of WiFi calling on the Samsung S25 is international travel. When you are outside your home country, cellular roaming charges can add up quickly. WiFi calling lets you bypass many of those costs by routing calls over the internet.

In many cases, you can use WiFi calling to call back to your home country as if you were still there, without paying international long-distance rates. Some carriers even treat incoming WiFi calls while abroad as free, depending on your plan. However, policies vary widely, so you should confirm the details with your carrier before you depart.

A useful travel tip is to enable Airplane mode on your Samsung S25 upon landing in a foreign country, then manually turn WiFi back on. This prevents the phone from connecting to foreign cellular towers and incurring roaming charges, while still allowing WiFi calls and messages over the hotel or café network.

Battery and Data Considerations

WiFi calling is generally light on data usage. A typical voice call consumes roughly 1 megabyte of data per minute, though this can vary based on codec and connection quality. For most users, this is negligible, especially when connected to an unlimited home or office internet plan.

From a battery perspective, WiFi calling can actually help your Samsung S25 last longer in certain situations. When cellular signal is weak, your phone increases radio power to maintain a tower connection, which drains the battery quickly. By switching to WiFi calling, the phone can use the more efficient WiFi radio instead, preserving battery life.

That said, if your WiFi signal is also weak, the phone may struggle to maintain a steady connection, which can increase power consumption. For the best battery performance, use WiFi calling when you have a strong wireless signal and keep your device updated so the modem firmware remains optimized.
