What Is WiFi Calling and Why It Matters

WiFi calling, sometimes called VoWiFi, routes your voice calls through a WiFi network instead of a traditional cell tower. When you enable it, your phone uses your internet connection to connect to your 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 settings.

This feature matters because cellular signals struggle with thick walls, concrete basements, elevators, and remote locations. If you have a strong WiFi connection but weak bars on your phone, WiFi calling can fill the gap. It is also useful when traveling internationally, as some carriers treat WiFi calls back to your home country as domestic calls, potentially saving you from roaming charges.

On Xiaomi devices, WiFi calling works alongside VoLTE (Voice over LTE). In many cases, you need VoLTE enabled before the WiFi calling option will even appear. The feature is baked into the system dialer, so you do not need to download a third-party app. Your regular phone number, contacts, and call history remain unchanged.

Does Xiaomi Have Wifi Calling? The Short Answer

Yes, Xiaomi does support WiFi calling, but it is not available on every device or in every market. If you are asking Does Xiaomi Have Wifi Calling?, the accurate answer is: it depends. Many recent Xiaomi, Redmi, and Poco smartphones include the capability, yet the toggle may be hidden or missing because of carrier restrictions, regional firmware differences, or older software versions.

Xiaomi typically enables WiFi calling on global and European ROMs for newer flagship and mid-range devices. However, phones sold in certain regions may have the feature disabled by default, or the carrier may not provision it for Xiaomi devices even if the hardware supports it. This is why checking your specific model and SIM provider is essential before assuming the feature will work.

Supported Xiaomi Models for WiFi Calling

Xiaomi has not published one universal list that covers every market, but WiFi calling is commonly found on recent Xiaomi, Redmi, and Poco devices released from roughly 2021 onward. Support is strongest on the Xiaomi 12, 13, and 14 series, as well as select Redmi Note and Poco F-series models. Older devices, such as the Mi 9 or Redmi Note 8 generation, generally lack the feature unless a specific carrier firmware enables it.

Below is a general reference for popular series. Exact support varies by region and carrier, so treat this as a starting point rather than a guarantee.

Series	Example Models	Typical WiFi Calling Status
Xiaomi 14 Series	Xiaomi 14, 14 Ultra	Yes, on most global and EU variants
Xiaomi 13 Series	Xiaomi 13, 13 Pro, 13 Ultra	Yes, widely supported on global ROMs
Xiaomi 12 Series	Xiaomi 12, 12 Pro, 12X	Yes, on many regional variants
Xiaomi 11T Series	Xiaomi 11T, 11T Pro	Yes, depending on carrier and firmware
Redmi Note 12 Series	Redmi Note 12, 12 Pro, 12 Turbo	Yes, on select global models
Redmi Note 11 Series	Redmi Note 11, 11 Pro, 11 Pro 5G	Limited; varies by region
Poco F5 / F4 Series	Poco F5, F4, F4 GT	Yes, on many international units
Poco X5 / X4 Series	Poco X5 Pro, X4 GT	Limited; carrier dependent

Chinese domestic ROMs often behave differently from global ROMs. If you imported a Xiaomi phone from China, the WiFi calling option may be missing entirely even if the same model sold in Europe supports it. Always verify the software version and region before purchasing a device specifically for this feature.

How to Check If Your Xiaomi Supports WiFi Calling

Before attempting setup, confirm that your device actually has the option. The easiest method is to open the Settings app and look for the menu directly.

1. Open Settings.
2. Tap SIM cards & mobile networks or Mobile network, depending on your MIUI or HyperOS version.
3. Select the SIM card you want to check.
4. Look for a toggle labeled WiFi calling, VoWiFi, or Calls over WiFi.

If you see the option, your phone supports it at the software level. If the menu item is missing, your device may still support it but the carrier has not provisioned it, or your firmware variant does not include the feature.

You can also dial *#*#4636#*#* on some Xiaomi devices to open a hidden testing menu. From there, look for phone information or IMS settings to see if WiFi calling is registered. This code does not work on every model, so do not rely on it as the only test.

Finally, contact your carrier and ask whether they support WiFi calling on Xiaomi devices. Some networks support the feature on iPhones and Samsung phones but have not certified Xiaomi models, even when the toggle exists in Settings.

Step-by-Step: How to Set Up WiFi Calling on Xiaomi

Enabling WiFi calling on a Xiaomi phone usually takes only a few minutes, but the exact path differs slightly between MIUI and HyperOS. Below are the steps for both.

Enabling WiFi Calling on MIUI

1. Connect your phone to a stable WiFi network.
2. Open Settings.
3. Go to SIM cards & mobile networks.
4. Tap the SIM card you use for calls.
5. Find and enable the WiFi calling toggle.
6. If prompted, enter or confirm your emergency address. Carriers require this so emergency services can locate you if you call 911 or your local emergency number over WiFi.
7. Restart your phone or toggle airplane mode on and off to refresh the network connection.
8. Make a test call while connected to WiFi with cellular data turned off to confirm the call routes through WiFi.

Enabling WiFi Calling on HyperOS

HyperOS is Xiaomi’s newer operating system that replaces MIUI on many recent devices. The menus are similar but may be renamed.

1. Open Settings.
2. Tap SIM cards & mobile networks or Mobile network.
3. Select your active SIM.
4. Locate WiFi calling or VoWiFi and switch it on.
5. Complete any emergency address prompt that appears.
6. Restart the device to register the change with the carrier.

Choosing Preferred Network Type

Some Xiaomi phones let you choose whether calls prefer WiFi or cellular when both are available. In SIM cards & mobile networks, look for Preferred network type or Calling preference. Selecting WiFi preferred ensures the phone uses your wireless network whenever possible, which is helpful in areas with poor cellular coverage.

Carrier Requirements and Compatibility

Even if your Xiaomi phone has the WiFi calling toggle, your carrier must activate the feature on your account. Not all mobile networks support Xiaomi devices for WiFi calling, and policies vary by country.

In the United States, Xiaomi phones are not sold through major carriers as often as Samsung or Apple devices. Unlocked Xiaomi models may work with T-Mobile’s WiFi calling if the device is VoLTE-capable and provisioned correctly, but AT&T and Verizon are more restrictive. Always confirm with the carrier before relying on the feature.

In the United Kingdom, networks such as EE, O2, Vodafone, and Three generally support WiFi calling on compatible smartphones. Xiaomi devices purchased directly from these carriers are more likely to be provisioned than imported units.

In India, Reliance Jio and Bharti Airtel offer WiFi calling on supported devices. Xiaomi phones sold through Indian retail channels usually work, but you may need to update to the latest MIUI or HyperOS build and enable VoLTE first.

Across the European Union, many national carriers support WiFi calling, but support for Xiaomi specifically depends on local certification. A phone bought in Germany may work with Deutsche Telekom, while the same model in another country might not be provisioned by a different network.

A key requirement across nearly all carriers is an active SIM card with a voice plan. WiFi calling is not a replacement for cellular service; it is an extension of it. You also typically need postpaid service, as many prepaid plans do not include WiFi calling.

Troubleshooting Common WiFi Calling Issues on Xiaomi

If the WiFi calling option is missing or calls fail to connect, try these steps in order.

Option Is Missing from Settings

• Update MIUI or HyperOS to the latest version. Carrier features are often added in software updates.
• Ensure VoLTE is enabled. WiFi calling usually will not appear unless VoLTE is active on your SIM.
• Check that your SIM is inserted in the correct slot. On dual-SIM Xiaomi phones, some features are limited to SIM slot 1.
• Contact your carrier to confirm they support WiFi calling on your specific Xiaomi model.

WiFi Calling Toggle Is On but Calls Fail

• Turn airplane mode on for 10 seconds, then off. This forces the phone to re-register with the carrier’s IMS server.
• Restart your router and phone to rule out local network issues.
• Make sure you are connected to a WiFi network with a stable internet connection. Public WiFi with captive portals may block WiFi calling traffic.
• Disable any VPN or proxy, as these can interfere with IMS registration.

Poor Call Quality or Dropped Calls

• Move closer to your WiFi router or switch to a 5 GHz band if available.
• Reduce the number of devices using bandwidth on the same network during the call.
• Check for battery optimization settings. Go to Settings > Apps > Manage apps > Phone > Battery saver and set it to No restrictions so the system does not kill the calling process.

Emergency Calls Over WiFi

Emergency calls may behave differently over WiFi. Always keep your emergency address updated in the WiFi calling settings. If you move to a new home or office, update the address immediately so first responders can locate you.

Xiaomi WiFi Calling vs Competitors

Xiaomi’s implementation is capable, but it is generally more carrier-dependent than what you find on Apple, Samsung, or Google devices. The table below compares how the major brands handle WiFi calling.

Brand	WiFi Calling Support	Setup Complexity	Carrier Dependency
Xiaomi	Yes, on select models	Moderate	High
Samsung	Yes, wide range	Low	High
Apple iPhone	Yes, most models	Low	Moderate
Google Pixel	Yes, most models	Low	Moderate

Apple and Google tend to enable WiFi calling broadly across unlocked devices, while Samsung works closely with carriers to provision support. Xiaomi sits in the middle: the feature exists on many phones, but you are more likely to encounter missing toggles or carrier refusals, especially with imported models.

Tips and Best Practices for Xiaomi WiFi Calling

• Keep your software updated. Xiaomi frequently releases MIUI and HyperOS patches that improve IMS stability and add carrier support.
• Enable VoLTE first. Most carriers require VoLTE before WiFi calling will activate or even appear in the menu.
• Use a 5 GHz WiFi band. If your router supports both 2.4 GHz and 5 GHz, connect to 5 GHz for lower latency and clearer voice quality.
• Set your emergency address. Do not skip this step. It is required by many carriers and can be critical during an emergency call.
• Test before you rely on it. Make a few test calls from different rooms in your home to confirm handoff and quality are acceptable.
• Disable battery restrictions for the Phone app. Xiaomi’s aggressive battery management can sometimes terminate background calling processes.
• Do not expect WiFi calling to replace cellular entirely. You still need an active SIM and a provisioned voice plan.
