Trouble-proof solutions to iPhone 12 calling issues

Giving calls and sending messages are the basis of the phone's functionality. What is the point of buying a costly device if it doesn’t even perform its primary functions, turning into a useless piece of metal? And when you purchase an iPhone 12, you want to enjoy all its power to the fullest, whether your device is new or second-hand. So it's really frustrating to encounter an iPhone 12 dropped calls error out of the blue. Let's puzzle out the causes of this bug and explore the best solutions to fix your Apple phone quickly!

Force restart to fix minor glitches

iPhone 12 and iPhone 12 Pro calling issues are often caused by simple firmware glitches. And reboot works well for fixing various technical errors, as it closes all programs and stops running processes.

We advise you to do a full phone shutdown for the best results:

  1. Open Settings > tap General > select Shut Down.
  2. Turn off your gadget by dragging the slider.
  3. Let the phone rest for about 20 seconds, and then turn it on.

Update your operating system or carrier settings

Your device may work improperly or slowly or trigger iPhone calls dropping if there are some updates that you need to install. It’s possible to update iOS in two ways (check to see if your device is Internet-connected):

Method 1:

  1. Enter Settings > hit General > spot and tap Software Update.
  2. Is there a firmware file? Tap Install Now.

Method 2 (more complex):

  1. Run iTunes on your PC.
  2. Connect your iPhone 12 via a charging cable or USB.
  3. Head to the Device tab.
  4. Open the Summary tab.
  5. Hit the Update button.

The carrier update also turns out to be a good iPhone 12 dropping calls fix. The procedure is simple. Make just a few clicks:

  1. Enter Settings > hit General > select About.
  2. If the system prompts an update, tap on it and confirm.

Switch the Airplane Mode on and off

Perhaps the problem of dropping iPhone calls lies in buggy wireless antennas or network glitches. To fix the situation and refresh the cellular connection, try switching the Airplane Mode on and off:

  1. Enter Settings > spot Airplane Mode > hit the slider to turn it on.
  2. Wait 20-30 seconds and hit the slider again to turn off the mode.


  1. Head to Control Center with a light swipe down.
  2. Hit the Airplane Mode icon.
Switch the Airplane Mode on and off

Repair faulty network settings

Corrupted network settings are another possible cause of dropped calls on iPhone 12. This sometimes happens for no apparent reason. Keep in mind that a network settings reset is a nice option to repair your problem, but your VPN, Wi-Fi, and Bluetooth settings will be lost.

Steps to follow:

  1. Enter Settings > hit General> select Transfer or Reset iPhone > tap on the Reset button.
  2. Choose the Reset Network Settings option.
  3. Provide your passcode.

  2. Get out the SIM tray with the ejector tool or push pin.
  3. Get out the SIM card and check it for damage or dirt.

Fix Date & Time settings

What to do? It's simple:

  1. Enter Settings > hit General > go to the Date & Time tab.
  2. Tap Set Automatically.
  3. Check that the Time Zone is also set correctly.

Close apps you don't use

When there are too many applications working in the background, your device simply can't take another action, and thus, you're faced with the “iPhone 12 calls breaking up” issue. It's not necessary to close all your tools, but the more tasks you end, the better your Apple phone will perform.

Here's how to quit background programs:

  1. Swipe up by bringing your finger to the center of the screen.
  2. Scroll right or left to view the running programs.
  3. Swipe up on the application you seek to quit.
