My iPhone Is Dropping Calls! Here’s The Real Fix.

Your iPhone keeps dropping calls and you don’t know why. Your iPhone has service, but it can’t seem to stay connected while you’re calling someone. In this article, I’ll explain why your iPhone is dropping calls and show you how to fix the problem for good!

Turn Your iPhone Off And Back On

If your iPhone has only dropped a few calls, there may just be a minor technical glitch that could be fixed by restarting your iPhone. Press and hold the power button until the “slide to power off” slider appears on your iPhone’s display. Swipe the small power icon from left to right to turn off your iPhone. Wait about 15 seconds, then press and hold the power button to turn your iPhone back on.

If you have an iPhone X, press and hold the Side button and either volume button to get to the “slide to power off” slider. After turning off your iPhone X by swiping the power slider, turn it back on by pressing and holding the Side button.

Check For A Carrier Settings Update

Sometimes when your iPhone is experiencing cellular or Phone app issues, there’s a carrier settings update available for installation. Carrier settings updates are released by your wireless carrier or Apple that enhance your iPhone’s ability to connect to your carrier’s cellular network.

To check for a carrier settings update on your iPhone, open up the Settings app and tap General -> About. Wait on this menu for about 15 seconds for a pop-up that says “Carrier Settings Update”. If an update is available, tap Update.

If this pop-up doesn’t appear after about 15 seconds, there probably isn’t a carrier settings update available. If a carrier settings update isn’t available, that’s okay! There are still a few steps we can try before you’ll have to contact your wireless carrier.

Update The Software On Your iPhone

It’s possible your iPhone is dropping calls because its running an outdated version of iOS, the software of your iPhone. To check for an iOS update, open the Settings app and tap on General -> Software Update. If an update is available, tap Download and Install.

Note: The version of iOS in the screenshot below may be different than the version of iOS ready to download and install on your iPhone.

The update process can take quite awhile, so make sure your iPhone has plenty of battery life. Check out our article if you have any issues updating your iPhone.

Eject And Reinsert Your iPhone SIM Card

Your SIM card is the piece of technology that connects your iPhone to your carrier’s cellular network and stores your iPhone’s phone number. Issues related to connecting to your carrier’s cellular network can sometimes be fixed by ejecting and reinserting the SIM card.

Check out the first page of our “iPhone says No SIM card” article to learn how to eject the SIM card on your iPhone. The SIM card tray are your iPhone is incredibly small, so we highly recommend reading our guide if you’ve never ejected a SIM card before!

Reset Network Settings

If your iPhone is still dropping calls, try reseting its network settings. When you reset network settings, all of your iPhone’s cellular, Wi-Fi, Bluetooth, and Virtual Private Network settings will be restored to factory defaults.

Note: Make sure you write down all of your Wi-Fi passwords before reseting the network settings. You’ll have to enter them again after the reset is complete.

To reset network settings on your iPhone, open up the Settings app and tap General -> Reset -> Reset Network Settings. You’ll be asked to enter your iPhone passcode, then confirm your decision by tapping Reset Network Settings. Once the reset is complete, your iPhone will restart.

Still Dropping Calls? Try Wi-Fi Calling!

If your iPhone is dropping calls, you may be able to temporarily work around the problem by using Wi-Fi calling. When Wi-Fi calling is turned on, your iPhone will be able to make phone calls using your Wi-Fi connection instead of your cellular connection.

To turn on Wi-Fi calling, open the Settings app on your iPhone and tap Cellular -> Wi-Fi Calling. Then turn on the switch next to Wi-Fi Calling on This iPhone. You can also turn on Wi-Fi calling by going to Settings -> Phone -> Wi-Fi calling.

Unfortunately, Wi-Fi calling isn’t supported by every wireless carrier, so you may not have this feature on your iPhone. Check out our article to learn more about Wi-Fi calling.

I had the identic same issue and performed every imaginable fix. The problem is the new iphone software only works on 5Ghz, therefore the fix is to disable 2.4Ghz on the WiFi router. Very simple to do. (For AT&T customers.) Go to your router’s address, like http://routerip/cgi-bin/home.ha and login with your credentials; go to Broadband; then under that go to wifi; you may need your router access code printed on the router; then advanced options; click disable on the 2.4Ghz; scroll to the bottom and click save. That‘s it.
Hope this helps.

I had an iPhone 10max which kept dropping calls or the person on the other end could not hear me. I just got an iPhone 11 Pro Max and the same thing is happening. I have Sprint as a provider and the sim card was installed at the apple store where I bought my phone. So frustrating and would really appreciate any help that you can offer.

I found a simple way to fix the “drop calls” problem. After hours of help from many sources I just removed and inserted the SIM card. Not a problem since then. My phone is four months old and it’s a Sony Xperia XA1.
