In this guide, I have explained the possible reasons why WiFi calling may not work on your iPhone. Usually, this feature comes in handy when cellular coverage is scarce in a region.

People who are newly using iOS may not have enabled WiFi calling on their devices. Hence, they aren’t able to use it. Again, the WiFi network on which the iPhone is connected may be unstable. As per some users, keeping the LTE enabled sometimes interferes with the WiFi calling feature. Also, if the iPhone is running on a buggy version of iOS, it will cause a lot of glitches including WiFi calling not working properly.

2. Enable WiFi Calling on iPhone

You must enable the WiFi calling feature on your iPhone. You must also keep in mind that unless your telecarrier doesn’t support WiFi calling activating it on the iPhone won’t do any good.

Later in this guide, I have mentioned how to check whether your tele-carrier supports WiFi calling if you are using their network on your iPhone.

For now, here are the detailed steps to enable WiFi calling on iPhone.

1. Open the Settings app.
2. Then navigate to Phone and tap on it.

4. On the next page, there will be an option for WiFi Calling on this iPhone.
5. Tap on the toggle beside the option to enable calling over WiFi.
6. A confirmation pop-up will show up. Tap on Enable to proceed.
   

3. Update iOS

In most cases, not upgrading the iOS to the latest build can lead to bug issues on the iPhone. This affects various other system apps and services. So, it is wise to update the iOS and this is how you do it.

1. Open the Settings app.
2. Then tap on General.
3. Next, tap on Software Update.
4. If the device is connected to the internet will start looking for available updates.

4. Toggle Between Flight Mode

Some users reported that toggling between the flight mode option has helped in fixing the WiFi calling unresponsive issue. It is quite easy to implement.

1. Open the Control center on the iPhone.
2. Tap on the flight mode button to disrupt the network.
   
3. After a few seconds, again tap on the flight mode button to enable all the networks.
4. Try to use WiFi calling feature and check if it is working or not.

5. Use Alternative WiFi Network

If it is possible for you then try to connect to another WiFi network. It may happen that the current WiFi your iPhone is connected to may be unstable. There may be an issue with the router or the ISP responsible for the WiFi may be undertaking some maintenance work. That may cause an unstable network or frequent WiFi disruption.

You may fix the WIFi network by taking help from your ISP or manually resetting the router. If the ISP is performing maintenance, then you have to wait until it is over. Then the WiFi should work fine and features like WiFi calling would work seamlessly.

6. Does your Network Support WiFi Call on iPhone?

You need to ensure that the Netwok that you are using on the iPhone supports WiFi calling or not. Apple has listed up tele-carriers all around the globe that support WiFi calling. You can check it here.

Click on your respective region and check whether the primary telecarriers support WiFi calling or not. Here, in India, for iPhone users, Airtel and Reliance Jio support WiFi calling whereas Vodafone Idea doesn’t support the feature.

7. Disable LTE on Your iPhone

Another quick fix to resolve WiFi calling issues includes disabling the LTE on your iPhone. Here is how to do it.

1. Go to the Settings app.
2. Then tap on Mobile Data > Mobile Data Options.
3. Under that, there will be an option to enable/disable LTE.
4. Simply tap on the toggle to disable the LTE if it is already enabled.

Note that, not all iPhone users will see the LTE option under Mobile Data Options. If only the carrier has provided an option for manually controlling LTE, then only you will have an option to enable or disable LTE.

8. Is the SIM Card Properly Inserted in the iPhone

In case, none of the above fixes bring any result in fixing WiFi calling then the SIM card may not be inserted properly in the iPhone. So, eject the SIM card from the iPhone. Use a clean cloth to wipe the SIM card and re-insert it back carefully into the SIM card slot and put the SIM in the iPhone.

Restart the iPhone and connect to an available WiFi network. Check whether you can place calls over WiFi. It at all it was the SIM card not inserted properly, the issue should be fixed.

So, try these methods out to troubleshoot the WiFi Calling Not Working on iPhone Mobile.
