iPhone 18 Pro Can’t Make or Receive Calls? How to Fix

It seems that many users notice that their iPhone 18 Pro can’t make or receive calls. I experienced this as well. At first, I thought it was just me and a glitch or maybe my network acting weird. But then it happened again… and again. Suddenly, I couldn’t make calls. My friends said they tried calling me, but my phone never rang. Sometimes, even FaceTime and WhatsApp calls would fail showing signs of a network-related issue. Restarting the phone seemed to help—but only for a few hours. It further seems that many people experienced similar issues.

I checked the Apple Forums and the Forums showed hundreds of other iPhone users were saying the same thing and these themes start to emerge: “call failed,” “call ended errors,” “no missed call logs,” or “calls just disappear.” And this isn’t limited to iPhone 18 Pro. The iPhone 18 Pro Max users are also facing this problem.

What Exactly Is the Issue?

These are the symptoms reported by users:

You can’t make or receive regular phone calls over cellular.
Incoming calls go straight to voicemail without ringing.
You miss calls, but they don’t show up in the call log, indicating no calls reached your phone. Note that you might not be able to receive calls if you have certain settings turned on.
FaceTime, WhatsApp, and even Teams calls drop suddenly or fail to connect. WhatsApp will say calling if the other party is not ringing.
SMS messages may not send, though iMessage continues working if it is turned on.
Restarting the phone temporarily fixes it—but only for a few hours or a day.

Some users also reported that even when calls do go through, they drop as soon as the screen lights up or when switching from Wi-Fi to cellular.

In this article, I’ve listed 8 fixes that will hopefully help you fix the problem.

What Fixes Have Worked for Some Users?

None of these are guaranteed, but users have reported temporary or partial success with the following steps:

1. Turn Off Wi-Fi Calling and Connectivity Assist

Go to Settings > Cellular > Wi-Fi Calling and turn it off. Also go to Settings > Wi-Fi and make sure Connectivity Assist is off.

Some users reported that this workaround helped on AT&T, Verizon, and other carriers.

2. Reset Network Settings

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.

Note: This will erase all current saved settings, including Wi-Fi passwords, preferred networks, and VPN and APN settings that you’ve used before.

3. Switch to LTE Instead of 5G

Some users had better luck after changing their network settings: Settings > Cellular > Cellular Data Options > Voice & Data → Choose LTE instead of 5G Auto or 5G On.

4. Restarting Your Phone Frequently

While annoying, some users found that rebooting the iPhone 18 Pro every few hours helped calls temporarily go through.

5. Use Speakerphone or Bluetooth Devices

It sounds odd, but some people reported that using speakerphone or connecting AirPods helped reduce the number of dropped calls.

6. Contact Your Carrier

Some carriers were able to push network resets or updates to individual accounts, which fixed the issue for a few users—especially with AT&T.

When you contact your carrier, make sure that:

Your account is set up to use your iPhone.
There aren’t any localized service outages.
Your account doesn’t have a billing-related block.
Your calls don’t have errors on the carrier system.

7. Install the Latest iOS Update

Some people said the issue disappeared after updating to the latest version of iOS, while others said it made no difference or even worsened the problem.

8. Check for a Carrier Settings Update

Carrier settings updates help your iPhone connect better to your mobile network and enable features like 5G and Wi-Fi Calling. When a carrier settings update is available, you’ll see a prompt to install it. Installation takes less than one minute.
