Wi-Fi Calling Not Working On iPhone? Here’s The Fix.

You’re trying to make a phone call, but you don’t have any service. Now would be a great time to use Wi-Fi calling, but that’s not working either. In this article, I’ll explain the steps to take when Wi-Fi calling isn’t working on your iPhone.

Wi-Fi Calling, Explained.

Wi-Fi calling is a great backup when you’re in an area with little or no cellular coverage. With Wi-Fi calling, you can make and receive phone calls using your connection to a nearby Wi-Fi network. Still, there can be problems that prevent this from working properly on your iPhone.

There are several reasons why Wi-Fi calling might not work on your iPhone. Here are a some steps you can take to try and fix the problem.

Restart Your iPhone

Sometimes, all you need to do to fix the problem is simply restart your phone. Press and hold the power button, then swipe the red power icon from left to right to turn off your iPhone. If you have an iPhone with Face ID, press and hold the side button and either volume button, then swipe the power icon across the display.

Double-Check Your iPhone Is Connected To A Wi-Fi Network

If you’re not connected, you won’t be able to use Wi-Fi calling. Head to Settings -> Wi-Fi and make sure a check mark appears next to the name of a Wi-Fi network. While you’re there, try turning Wi-Fi off and back on. It may fix a minor software bug!

Make Sure Wi-Fi Calling Is Turned On

Head to Settings -> Cellular -> Wi-Fi Calling and turn it on. If you don’t see this option, your cell phone plan doesn’t include Wi-Fi calling. Check out our cell phone plan comparison tool to find a new plan that does.

Eject And Reinsert The SIM Card

Similar to restarting your iPhone, rebooting your SIM card may be all it takes to fix the problem. Check out our other article to learn where the SIM card tray is on your iPhone. Once you’ve found it, use a SIM card ejector tool or a straightened out paperclip to eject the SIM card. Push the tray back in to reseat your SIM card.

Reset Network Settings

To do this, go to Settings -> General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings. This erases your Wi-Fi settings, so you’ll have to reenter your passwords after the reset is complete. Keep in mind that this will it also reset the Cellular, VPN, and APN settings on your iPhone.

Spoiler: Make sure your carrier has your current physical address updated correctly! Came across this blog while I had the issue described–couldn’t get Wi-Fi Calling to enable. (Kept on getting the error message to contact my carrier.) Well, I had contacted my carrier, and spent *hours* on their chat tech support. Basically they walked me through all the steps outlined above. Finally they threw up their hands and said I needed to take my phone to an authorized service center; they felt it was a hardware issue b/c other members of my household could get their Wi-Fi Calling game on… Read more »

Straight Talk says my iPhone 6 needs to be replaced to a wifi calling capable phone. Of course, they offer phones to do just that. My iPhone 6 should be wifi calling capable. What’s up with this? I do not have the option to simply turn on wifi calling.

iPhone XSMax. Since 16.0 came out I have to have a bar of signal to use Wi-Fi calling!! I use Wi-Fi calling because I do NOT have signal where I live. Therefore it removed my access to phone!

I wonder if you can help with a definitive answer: I am about to purchased a factory unlocked iPhone (in the UK) for the sole purpose of using my own (US number) SIM for which I pay monthly for a no contract plan from Tello. I need to use Wi-Fi calling to be able to send / receive texts. Will I be able to enable Wi-Fi calling on the phone? Thanks in advance!

Can’t get Wi-Fi Calling to work. It stopped all of the sudden.
Wi-Fi calling is on.
I’ve done a network reset.
I’ve removed the SIM card.
I’ve restarted the phone.
Nothing ?
It used to work.

It’s possible that Wi-Fi calling is not supported by your carrier. You may want to reach out to them for clarification.

May be worth mentioning, if you are hooked up on Alexa for one number, it will cut off your WiFi calling on your phone. Vodafone UK

Wi-Fi calling may be dependent on your wireless carrier. They may not have given you the option to use this feature. That may be why Wi-Fi calling is not working on your iPhone 8

Here is another fix that works. I’m told this is an iPhone issue. Go to settings, cellular, cellular data options and turn off LTE. It will force the iPhone into WiFi calling. Make sure your WiFi calling is turned on of course as well. Also, don’t forget to turn LTE back on when you leave the house. I have the 11 ProMax. Worked perfectly for me. T-Mobile is my carrier.

This is literally the only thing that worked…I suspect Apple and the carriers aren’t to worried about patching this obvious software bug. The Galaxy S-10 just works when you turn WiFi Calling on. Both phones are AT&T.

My iPhone 6 was refusing to make or receive WiFi calls. Checked all the relevant settings were correct and tried switch off/switch on without success. What DID work was selecting “WiFi Assist” to ON. Go to Settings/Mobile Data/ and scroll down past the apps (on my phone it comes after “Find iPhone”)

On an iPhone 14 Pro, on the Cellular Data Options menu, we don’t have LTE switch. We have 1-Data Roaming (on/off) 2-Voice & Data (dropdown) 3-Data Mode (dropdown). Under 2, we have a choice of 5G On, 5G Auto, LTE. I use 5G Auto. I must reboot phone frequently to use WiFi calling. Any suggestions?

I’ve had same problem with new IPhone 14 through TMobile. They even gave me a 2nd phone but never could receive my calls. Now I have an Android which I hate and a new IPhone sitting in my closet!
