Fix: iOS 15 Wifi calling not working on iPhone or iPad

There are many reasons why WiFi calling not working on iPhones and iPad. Device owners don’t have to pay a single penny on services to fix the problem because this could have happened due to software-related or incorrect configuration. You don’t need additional tools to fix Wi-Fi calling problems but make sure to confirm that your carrier supports it.

Make sure to enable WiFi calling feature on iPhone or iPad

Many iOS users don’t have knowledge about Wi-Fi calling feature because it is a relatively new feature. Manufacturers contact the carrier and create an integration with them, which helps the device to take advantage of the feature.

  • Tap on the Settings > Cellular / Mobile Data > Wi-Fi calling.
  • Click to enable “Wi-Fi Calling on This iPhone”.
  • A pop-up shows up on the screen and tap on “Enable” to turn it on.

Wi-Fi calling is enabled and you have to connect the iPhone or iPad to the Wi-Fi network.

Wi-Fi calling is all about using your internet connection to make calls but it requires an active carrier connection. Nobody wants to do free service, do not assume that your network will provide the service for free of cost. Call carrier customer care to confirm, whether the Wi-Fi calling is supported or not because this is a fairly new feature in parts of the world.

Restart iPhone or iPad

Do not apply any solution without restarting the iPhone or iPad. Millions of iOS devices don’t get sleep time, and that’s when the software accumulates trash. iOS is optimized, but it doesn’t mean it doesn’t have any shortcomings. You should let the iOS device sleep time because it will dump the previous session data and cool down the internals.

  • Tap on the Settings > General > Shut Down.
  • Toggle the right side to shut down the iOS device.

Reboot Router or Modem

Your Wi-Fi router plays a major role in the calling feature, and that’s the heart of it. There is nothing wrong with rebooting the router, and it won’t bring any harm until or unless you click something else. A quick reboot will give the machine rest and replenish the software.

  • Power off the router/modem.
  • Let the router/modem sleep for five minutes.
  • Turn the power back on and connect the iPhone or iPad again.

Check if Wi-Fi calling is working or not, and if you have a Wi-Fi router and modem, then reboot them.

Turn on Airplane Mode and turn it off

Your iOS device might be struggling to do multiple things at once, and in such a case, you can turn off all connectivity lines and then try again later.

  • Tap on the Settings > Airplane Mode to enable it.
  • Click on “Airplane Mode” to disable it.

Airplane mode will cut off all connectivity lines, which will force the Wi-Fi calling feature to work next time when you turn it back on. A simple solution like this works on iPhone and iPad because this is more or less a software-related issue.

Reset iOS Device

Your iOS device might have corrupted system files or threats, which is a common problem that Apple is aware of it. Fortunately, you have an option to reset the iOS software and start an afresh journey, which I have did in the past to solve software-related issues.

Update device with the latest iOS version

Your device should have iOS 10 or later installed to use Wi-Fi calling feature.

Apple released a new iOS version with improvements, and it can make good use of the technology. Read online news and iOS version reviews to ensure that it doesn’t have bugs or glitches that can create problems for you.

  • Tap on the Settings > General > Software Update.
  • Tap on “Download & Install” to begin the process.

Make sure to connect your device to a Wi-Fi network and ensure that it has a 90% battery charge. Create data backup in Windows PC or Mac using iTunes because iCloud backup takes a lot of time and energy.

Bottom Line

Wi-Fi calling is a software-based feature that requires integration from carriers. We implore the readers to speak with carrier customer care to ensure that your connection package and network support it.
