How Does Wi-Fi Calling Work?

Wi-Fi calling lets you make phone calls using a Wi-Fi connection instead of your mobile network. It’s especially helpful in places where cell signals are weak or unreliable. Whether you’re at home, in a cafe or somewhere with free Wi-Fi, you can still make clear, uninterrupted calls as long as your Wi-Fi is stable.

To use it, you just need to turn on the Wi-Fi calling feature on your device. But be cautious when using public Wi-Fi, since it might not be secure. This feature is super useful, but if it’s not working, the next steps will help you figure out why and how to fix it.

What Causes Wi-Fi Calling to Not Work on Android Phones?

Most issues with Wi-Fi calling on Android happen because of poor internet connectivity. If your Wi-Fi signal is weak or your internet is too slow, Wi-Fi calling won’t work properly. Sometimes, the problem comes from your router, so it’s a good idea to check if your Wi-Fi is working as it should.

Another common cause is that the Wi-Fi calling feature may be turned off by mistake. Also, if your phone is in Airplane mode and Wi-Fi isn’t turned back on manually, the feature won’t work. Lastly, not all mobile carriers support Wi-Fi calling, so that might be the issue too.

How to Fix it When Wi-Fi Calling Isn’t Working On an Android

If Wi-Fi calling isn’t working on your Android, the first thing to check is whether the feature is turned on in your phone’s settings. Sometimes, it gets disabled after a system update or by mistake. It’s also important to make sure you’re connected to a strong and stable Wi-Fi network weak or unstable signals are one of the most common reasons Wi-Fi calls fail.

Other quick fixes include restarting your phone, switching Airplane mode on and off, or resetting your network settings. Some users have also found success by updating their phone’s software or reinserting the SIM card. If none of these work, it might be worth checking if your carrier even supports Wi-Fi calling.

How to Fix the WiFi Calling Not Working (Android)

Device and Carrier Compatibility For Wifi Calling Stopped

Wi-Fi calling suddenly stopped working, it could be due to your device or carrier not fully supporting the feature. Some Android phones especially older or budget models may not support Wi-Fi calling at all. Also, if your phone software is outdated or your SIM card hasn’t been properly provisioned by the carrier, the feature may not work even if it’s enabled in settings.

Key things to check for compatibility:

• Software Update: Make sure your phone has the latest Android updates installed.
  
• Phone Compatibility: Not all phones support Wi-Fi calling double-check with your carrier or manufacturer.
  
• Carrier Provisioning: Your SIM must be provisioned by the carrier for Wi-Fi calling to work.
  
• Carrier-Specific Tips:
  
  • T-Mobile/Metro (US): Enable Wi-Fi Calling Preferred and dial #932# to check.
    
  • Verizon (US): Turn on Advanced Calling under LTE settings.
    
  • Airtel (India): Use the MyAirtel App to activate VoLTE and VoWiFi.
    
  • Jio (India): Use code *#*#4636#*#* to check IMS Registration.

Advanced Troubleshooting

The basic fixes don’t solve the issue, there’s one more simple but often overlooked step that can help: reinsert your SIM card. Some users have found that removing the SIM, cleaning it gently (for example, with a little isopropyl alcohol), and putting it back in fixed their Wi-Fi calling problems.

Even though it sounds basic, it can reset your phone’s connection with the network and refresh the carrier provisioning. Just make sure the SIM card is dry and clean before reinserting it.

Beyond Common Sense: My Unusual Fixes

Fix 1: VPN Interference

Sometimes, VPNs can interfere with Wi-Fi calling and cause it to stop working. This is because VPNs can block or reroute the traffic needed for the service to connect properly.

Key takeaway:
If you’re using a VPN, try turning it off while using or troubleshooting Wi-Fi calling. Many users have found that simply disabling the VPN fixes the issue immediately.

Fix 2: Router Channel Congestion

If you’ve noticed Wi-Fi calling not working properly, especially in places like apartment buildings, router channel congestion could be the reason. When too many routers use the same channel, your signal can get weak or unstable, leading to dropped or poor-quality calls.

One easy fix is to use a Wi-Fi analyzer app to check which channels are crowded. Then, go into your router settings and switch to a less congested channel this small change can make a big difference in how well Wi-Fi calling works.

Fix 3: Faraday Effect

Sometimes, the problem with Wi-Fi calling not working isn’t your phone or network—it’s your surroundings. Objects made of metal, like filing cabinets or thick walls, can block wireless signals by creating what’s known as a Faraday effect.

Key takeaway:

• Metal objects around your phone can weaken or block Wi-Fi signals.
  
• Try moving to a different spot in your home or office if calls keep dropping in one area.
  
• Even something as simple as shifting your desk can fix the issue instantly.

Fix 4: Firmware Rollback

Sometimes, a router firmware update can accidentally break Wi-Fi calling. This has happened to users who noticed the feature stopped working right after updating their router.

Key takeaway:

• If Wi-Fi calling suddenly stops after a firmware update, try rolling back to a previous version.
  
• It’s a good idea to check online forums or support pages before updating your router firmware in the future.

Fix 5: DNS Shenanigans

Changing your DNS settings can sometimes improve or fix Wi-Fi calling issues. Some users have noticed that using public DNS servers like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1) works better than their default ISP settings.

However, results can vary depending on your network setup. What works for one person may not work for another, so it’s a bit of trial and error. If you’re unsure, it’s best to check with your carrier or a tech expert before making changes.

Additional Tips

Still facing trouble with Wi-Fi calling not working? Go into the phone’s settings and look for options to set call preferences. Some devices allow prioritizing Wi-Fi for calls instead of the mobile network, which can make a big difference.

When all other steps don’t solve the issue, the next best move is to contact the carrier’s support team. They can check backend settings or provisioning problems that aren’t visible on the device.

Confirm Wi-Fi Is Enabled and Working

Having trouble with Wi-Fi calling not working  First, make sure Wi-Fi is turned on. Use the Quick Settings panel or go to Settings > Network & internet > Wi-Fi to double-check.

Also, weak signals or interference can cause problems. Try moving closer to the router and avoid being near devices like baby monitors or Bluetooth speakers that use 2.4GHz.

Battery saver and hotspot features can also interfere with your connection. Turn them off to see if that helps fix Wi-Fi calling not working issues.

Is Wi-Fi Calling Enabled?

Many phones don’t have Wi-Fi calling turned on by default, which is often why the feature isn’t working. To get it running, the setting needs to be enabled manually through your phone’s settings.

Go to the Settings app, then either search for “Wi-Fi calling” or navigate to Network & internet > Mobile network. Once found, switch the toggle on. On some Android devices, the exact location of this option may vary slightly. After enabling it, a Wi-Fi icon should appear next to the carrier signal at the top of the screen.

Check if Your Phone and Carrier Offer Wi-Fi Calling

To use Wi-Fi calling, both the phone and the mobile carrier must support the feature. If the option doesn’t appear in the device’s settings, it might not be available on that model.

Check the manufacturer’s website to confirm if the phone supports Wi-Fi calling. Then, contact the carrier to make sure they offer it too. If either one doesn’t support it, the feature won’t work.

Check for New Software Updates

Sometimes, Wi-Fi calling doesn’t work just because the phone’s software is outdated. New updates often include bug fixes that can solve unexpected issues, including problems with calling over Wi-Fi.

To check for updates:

• Open the Settings app
  
• Tap System (or About phone on some devices)
  
• Go to System update or Updates
  
• Tap Check for updates and install any available updates

Use Airplane Mode to Force Wi-Fi Calling

Sometimes, even with Wi-Fi calling turned on, the phone may still use the mobile network if the signal is strong. This can prevent calls from going through Wi-Fi, especially in areas where cellular coverage is good.

A simple workaround is to enable Airplane Mode, which turns off all wireless connections. Then, turn Wi-Fi back on manually. This forces the phone to use Wi-Fi for calls by disconnecting it from the mobile network. Just remember to switch off Airplane Mode afterward to resume normal service.

Restart Your Router and Phone

When Wi-Fi calling stops working, one of the easiest and most effective steps is to restart both your phone and router. Temporary glitches in your device or network often get fixed with a simple reboot.

To restart an Android phone, press and hold the Power button until options appear, then tap Restart. For your router, unplug it from power, wait a few seconds, then plug it back in to complete a proper reset.
