iOS updates are known to bring new and exciting features. Unfortunately, a few updates can also bring a minor bug alongside it, and the same is the case with the iOS 17.5.1 update as well. If you are someone who enjoys calls over Wi-Fi when cellular coverage is limited, avoid updating your iPhone to iOS 17.5.1.
And if you already did, fret not; I am here to help. In this post, I have curated a list of troubleshooting tips to help you fix the Wi-Fi call not working issue.
Why my Wi-Fi calling is not working on iPhone?
There are several different reasons why Wi-Fi calls might not work on your iPhone. A shoddy internet connection and software glitches in a new iOS version, such as iOS 17.5.1, are among the things known to cause problems with Wi-Fi calling.
The only way to know for sure is by systematically troubleshooting the cause of the error, which is exactly what I have detailed in the next section.
How to fix Wi-Fi calling not working after iOS 17.5.1 update
1. Check if your iPhone is connected to Wi-Fi
It is pretty apparent that you can’t use Wi-Fi calling if your phone isn’t connected to a Wi-Fi network.
Go to Settings → Wi-Fi and check whether you’re connected to a Wi-Fi network. If not, connect to one.
You can also check if the connection is actually working by opening your browser and visiting any website you like.
If it’s working well, try the next solution below.
2. Make sure Wi-Fi Calling is turned on
- Go to Settings and tap Cellular.
- Now, tap Wi-Fi Calling and make sure it’s toggled on.
3. Reset Network Settings
Resetting your Network Settings may fix Wi-Fi calling not working on your iPhone. Here’s what to do:
- Go to Settings → General → Transfer or Reset iPhone.
- Now, tap Reset → Reset Network Settings. Enter your passcode and tap to confirm and erase your Wi-Fi settings.

4. Restart your iPhone
Sometimes, simply rebooting your iPhone can fix the problem. To do so:
If your iPhone has a Home button:
- Press and hold the Sleep/Wake and Home buttons simultaneously until the power slider appears.
- Swipe it to the right to turn off your iPhone.
- Wait a few moments and press and hold the power button until the Apple logo appears on the screen.
If your iPhone has no Home button:
- Press and hold the Side and Volume buttons simultaneously on an iPhone X or newer model until the power slider appears.
- Swipe it to the right to turn off your iPhone.
- Wait a few moments and press and hold the power button until the Apple logo appears on the screen.
5. Erase All Content and Settings on iPhone
This is a pretty extreme step, as it will restore your iPhone to its factory default settings. Make sure you have a backup of all your data ready before proceeding with this step.
See our in-depth guide on how to factory reset your iPhone for more information.
6. Contact your wireless carrier
If none of the above steps work to fix Wi-Fi calling on your iPhone, you should contact your wireless carrier and explain the situation to their support staff.
It’s possible there’s an issue with your account, and a customer service representative could help you resolve it.
