What Is Wi-Fi Calling?

Wi-Fi calling is a feature that lets you make and receive phone calls and text messages over a Wi-Fi network instead of relying solely on your carrier’s cellular signal. When you are in an area with weak or no mobile coverage, such as a basement, a rural home, or a large office building, Wi-Fi calling can route your voice traffic through your internet connection. The call still uses your regular phone number, and to the person on the other end it looks like a normal call.

The technology behind Wi-Fi calling is based on Voice over IP (VoIP), but it is tightly integrated with your carrier’s network. Unlike third-party apps such as WhatsApp or Skype, carrier-based Wi-Fi calling does not require the other person to have the same app installed. It works seamlessly with the native dialer and messaging apps on your Samsung Galaxy A35.

Does Samsung A35 Have Wifi Calling?

Yes, the Samsung Galaxy A35 supports Wi-Fi calling. The device is equipped with the necessary hardware and software to handle voice calls over Wi-Fi, provided your mobile carrier supports the feature and has provisioned it on your line. Samsung includes Wi-Fi calling support across most of its modern mid-range and flagship devices, and the Galaxy A35 is no exception.

However, simply having a compatible phone is not enough. Your carrier must offer Wi-Fi calling in your region, your plan must include it, and you must enable the setting on the device. In some cases, carriers push a software update or configuration profile that activates the option in your phone’s settings. If you do not see the toggle, it may be because your carrier has not enabled it yet or your SIM profile needs refreshing.

How Wi-Fi Calling Works on the Galaxy A35

When you enable Wi-Fi calling on the Samsung Galaxy A35, the phone constantly monitors both your cellular signal and your Wi-Fi connection. If cellular coverage drops below a usable threshold, or if you are connected to a strong Wi-Fi network, the phone may automatically route the call over Wi-Fi. Some carriers allow you to choose a preferred mode, such as “Wi-Fi preferred” or “Cellular preferred,” giving you control over which network takes priority.

Behind the scenes, the Galaxy A35 establishes a secure tunnel to your carrier’s IMS (IP Multimedia Subsystem) core. Your voice is encoded, packetized, and sent over the internet to the carrier, which then connects it to the traditional telephone network. This means call quality depends heavily on your internet speed, latency, and the stability of your Wi-Fi router.

Supported Voice Codecs

The Galaxy A35 typically uses standard voice codecs such as AMR-WB (Adaptive Multi-Rate Wideband) for high-definition voice. When connected over a robust Wi-Fi network, you may experience clearer audio compared to a weak cellular signal. The phone automatically negotiates the best available codec with your carrier’s network.

Carrier Support and Requirements

Carrier support is the single biggest factor in whether Wi-Fi calling works on your Galaxy A35. Major carriers in the United States, United Kingdom, Canada, Australia, and many European countries support Wi-Fi calling on Samsung devices. Smaller regional carriers and MVNOs (Mobile Virtual Network Operators) may or may not offer the feature.

To use Wi-Fi calling, you generally need:

• A compatible SIM card and an active line with a carrier that supports Wi-Fi calling.
• A valid E911 emergency address registered with your carrier, since emergency services need to know your location when calling over Wi-Fi.
• A stable Wi-Fi connection with sufficient bandwidth and low latency.
• The latest software updates installed on your Galaxy A35.

If your carrier does not support Wi-Fi calling, the toggle will not appear in settings, and no amount of troubleshooting on the phone will enable it.

How to Enable Wi-Fi Calling on Samsung A35

Enabling Wi-Fi calling on the Samsung Galaxy A35 is straightforward. Follow these steps to turn on the feature and configure your preferences.

Step-by-Step Instructions

1. Open the Settings app on your Galaxy A35.
2. Tap Connections.
3. Select Wi-Fi Calling.
4. Toggle the switch to On.
5. If prompted, enter or confirm your emergency address for E911 service.
6. Choose your preferred calling mode, such as Wi-Fi preferred or Cellular preferred, depending on what your carrier offers.
7. Return to the home screen and test by making a call while connected to Wi-Fi.

If you do not see the Wi-Fi Calling option under Connections, ensure your phone software is up to date by going to Settings, then Software update, then Download and install. You may also need to contact your carrier to activate the feature on your account.

Quick Settings Shortcut

You can also add a Wi-Fi calling toggle to your Quick Settings panel. Swipe down from the top of the screen with two fingers, tap the three-dot menu, select Edit buttons, and drag the Wi-Fi calling icon into your active panel. This lets you turn the feature on or off without digging through settings.

Troubleshooting Wi-Fi Calling Issues

Even when Wi-Fi calling is supported, you may encounter issues. Here are the most common problems and how to fix them.

Wi-Fi Calling Toggle Is Missing

If the toggle is absent, first confirm that your carrier supports the feature. Then check for software updates and restart your phone. You can also try reinserting your SIM card or contacting your carrier to refresh your line provisioning.

Calls Drop or Sound Poor

Poor call quality usually stems from an unstable Wi-Fi connection. Move closer to your router, switch to a less congested band (5 GHz if available), or restart your router. Ensure no heavy downloads are running in the background that could consume bandwidth.

Emergency Address Errors

If the phone repeatedly asks you to verify your emergency address, update it in Settings under Wi-Fi Calling, or contact your carrier directly. An incorrect or missing E911 address can prevent Wi-Fi calling from activating.

Wi-Fi Calling vs VoLTE

It is easy to confuse Wi-Fi calling with VoLTE (Voice over LTE), but they serve different purposes. VoLTE uses your carrier’s 4G LTE network for voice calls, improving call quality and allowing simultaneous voice and data usage. Wi-Fi calling, on the other hand, routes calls over a Wi-Fi network when cellular signal is weak or unavailable.

On the Samsung Galaxy A35, both features can be enabled at the same time. The phone will intelligently choose the best available network based on your settings and signal strength. If you are on a strong LTE signal, VoLTE handles the call; if you move into a Wi-Fi-only area, Wi-Fi calling takes over.

Network Bands and Compatibility

The Samsung Galaxy A35 supports a wide range of network bands, including 5G, 4G LTE, 3G, and 2G, depending on your region and variant. Wi-Fi calling is not dependent on these cellular bands, but your carrier’s VoLTE and IMS configuration must be compatible with the device. Most global variants of the Galaxy A35 are certified for Wi-Fi calling on major carriers.

If you purchased an unlocked device and use it with a carrier different from the original, Wi-Fi calling may still work, but you might need to contact the new carrier to ensure the device is whitelisted and provisioned correctly.

Tips and Best Practices

To get the most out of Wi-Fi calling on your Samsung Galaxy A35, keep these tips in mind:

• Always keep your phone’s software updated to receive carrier configuration improvements.
• Use a strong, stable Wi-Fi network with at least 1 Mbps of upload and download bandwidth for reliable calls.
• Enable Airplane Mode and then turn Wi-Fi back on if you want to force all calls over Wi-Fi in areas with no cellular coverage.
• Register an accurate emergency address and update it whenever you move or travel.
• Avoid using public Wi-Fi hotspots for sensitive calls, as security and quality may vary.
• Restart your phone periodically to refresh network connections.

Using Wi-Fi Calling Internationally

One of the biggest advantages of Wi-Fi calling is its usefulness while traveling abroad. If your carrier supports international Wi-Fi calling, you can make and receive calls and texts over Wi-Fi without incurring roaming charges, as long as you are connected to a Wi-Fi network. This can save you significant money on international roaming fees.

However, policies vary widely by carrier. Some allow free Wi-Fi calling to domestic numbers while abroad, while others may charge per minute. Always check your carrier’s international Wi-Fi calling policy before traveling. Additionally, emergency calling while abroad over Wi-Fi may not connect to local emergency services, so use local cellular networks for emergencies.
