Wi-Fi Calling Not Working on iPhone? Here’s How to Fix It 2026

Wi-Fi calling is a great feature provided by iPhone to its users. It allows you to make and receive calls over a Wi-Fi network when cellular coverage is weak or unavailable. However, it can be frustrating when Wi-Fi calling suddenly stops working on your iPhone. Users report that WiFi calling is not working on iPhone after the iOS 26 update. It may be due to connectivity problems with either the phone or the network, or Wi-Fi calling might have been accidentally turned off. Additionally, issues with your device’s software, router, or SIM card can cause problems. If you’re experiencing issues with Wi-Fi calling on your iPhone, particularly after recent iOS updates, here are step-by-step solutions to fix and get it working again.

What is Wi-Fi Calling?

Wi-Fi calling gives you the chance to make phone calls using a wireless internet connection. It doesn’t go through a traditional telecommunications provider like AT&T or Verizon. Additionally, Android and iOS devices now support universal standards (APIs) for VoIP calls, optimized for battery life and user experience. In short, Wi-Fi Calling is a game-changing technology that enables customers to make and receive calls over Wi-Fi using their existing cellular connection.

It uses Voice over Internet Protocol (VoIP) technology to route calls over the internet to your mobile service provider’s network

Why Is Wi-Fi Calling Not Working on My iPhone?

Wi-Fi calling may not work due to several factors, including an unstable Wi-Fi connection, outdated software, issues with your device settings, or problems with your carrier’s support or settings.

• Wi-Fi Calling Disabled: The feature might be turned off in your iPhone settings or not properly configured.
• Unstable Wi-Fi Connection: A weak or inconsistent Wi-Fi signal can prevent Wi-Fi calling from working effectively.
• Carrier Compatibility Issues: Not all carriers or plans support Wi-Fi calling, or there may be account-specific settings that need adjustment.
• iOS Software Glitches: Updates like iOS 18, 26 or their beta versions have been reported to cause Wi-Fi calling issues for some users.
• Router or Network Problems: Your Wi-Fi router or Internet Service Provider (ISP) may be blocking required ports or running outdated firmware.
• Device-Specific Issues: Older iPhone models or certain configurations may experience Wi-Fi calling issues after software updates.
• Carrier Settings Outdated: Missing carrier updates can disrupt Wi-Fi calling functionality.

Restart your iPhone

Sometimes, all you need to do is simply restart your device as restarting your device might be helpful to clear some of the bugs and will definitely help you to deal with the issue. A normal restart is good where you have to switch off your device and then restart it, but here we will suggest you do a hard restart as it is more effective! Here’s how to do that,

Minor software glitches can interfere with Wi-Fi calling.

• Press and hold the Side Button + Volume Up/Down
• Slide to power off
• Wait 30 seconds and restart the device
• After reboot, reconnect to Wi-Fi and check the feature

Check if your issue has been solved; if not, then move to other troubleshooting solutions.

Make sure the Wi-Fi Calling feature is turned on

Again, if Wi-Fi Calling is not enabled, you can’t use it. Before proceeding, ensure this feature is enabled.

How to Turn On Wi-Fi Calling on iPhone?

• Open Settings > Phone > Wi-Fi Calling
• Toggle Wi-Fi Calling on This iPhone to On
• Tap Enable if prompted to confirm

If you don’t see the above options, then your cell phone plan doesn’t include Wi-Fi calling.

Disable and Enable Wi-Fi Calling

This solution may seem useless, but the issues that you’re facing with Wi-Fi calling may be temporary and could be easily resolved by turning the feature off and on again.

To do this,

• Open the settings app on your device
• Tap on the cellular network
• Then Tap on the Wi-Fi Calling Option
• Use the toggle to quickly enable and disable the feature.

Check device is connected to the Wi-Fi network

Wi-Fi Calling works only when you are connected to a stable Wi-Fi network. So, if you’re not connected, you won’t be able to use Wi-Fi calling.

• Make sure you’re connected to a reliable Wi-Fi network
• Restart your router if needed
• Move closer to the Wi-Fi access point
• Avoid using public networks with firewalls that block VoIP

Note: Wi-Fi calling may not work on captive portals (such as hotel or airport Wi-Fi that requires a web login).

Reinsert the SIM Card

Similar to restarting your iPhone, rebooting your SIM card may be all it takes to fix the problem. All you have to do is take a SIM card ejector tool, remove your SIM card tray, and again push the tray back in to reseat your SIM card.

• Power off your iPhone
• Use a SIM ejector tool to remove the SIM
• Wait a few seconds and reinsert it properly
• Power on your iPhone and check if the issue is resolved

Again some VPNs or apps like security firewalls can block VoIP services:

• Go to Settings > VPN
• Toggle VPN off or delete the profile temporarily
• Restart your iPhone and try Wi-Fi calling again

Enable and disable airplane mode

Airplane Mode disables Bluetooth and Wi-Fi and turns off the phone’s ability to connect to cellular networks. So, by enabling and disabling Airplane mode on your iPhone, you’re effectively restarting features like cellular connection, Wi-Fi connection, and Wi-Fi calling, too. Here’s how you can do that,

• Swipe down to open Control Center
• Turn on Airplane Mode, wait 10 seconds
• Turn Airplane Mode back off
• Reconnect to Wi-Fi and check if Wi-Fi calling works

Update iOS and Carrier Settings

Again running outdated iOS or carrier settings can break Wi-Fi calling.

• Go to Settings > General > Software Update
• Install any available iOS updates

For carrier settings:

• Go to Settings > General > About
• If an update is available, a prompt will appear

Reset Network settings

If you reset your network settings, it will erase your Wi-Fi settings, so you’ll have to re-enter your passwords after the reset is complete. Keep in mind that this will also reset the Cellular, Bluetooth, VPN, and APN settings on your iPhone. So that all networks will start as new and this will definitely help you to solve the issue.

How to reset your network settings?

• Go to Settings > General > Transfer or Reset iPhone
• Tap Reset > Reset Network Settings
• Enter your passcode to confirm.

Contact your Wireless Carrier

If nothing above has worked, there is an issue in your wireless network carrier. So,it may be worthwhile getting in contact with your wireless carrier. There could be an issue with your account that only a customer service representative can resolve.
