Troubleshooting an iPhone X that cannot make phone calls in iOS 13

Temporary network problems affecting cellular services, account-related issues, incorrect settings, invalid recipient number, and firmware issues are the common factors that can possibly ruin your phone’s basic calling functions. In other cases, the problem is attributed to some damaged components like a corrupted or damaged SIM card. Before opting for service, I’ve managed to line up a few helpful workarounds that are used to eliminate common factors that caused you this trouble. Don’t forget to make a test call after each method to determine whether or not the problem is resolved.

Before you begin troubleshooting, check your signal. If your iPhone is getting an unstable cellular signal, then that’s likely the underlying cause and therefore you have to deal with that first. You can move to another location where signal strength is stronger and stable. If there’s no problem with the cellular signal your iPhone is getting and yet it’s unable to make phone calls, eliminate software-related factors with these mapped out solutions.


First solution: Turn cellular off and on.

Cellular services should work for as long as the cellular feature of your iPhone is enabled. In case the recent iOS update had ruined your network settings and caused its cellular system to flaw, restarting it would be necessary. Thus, this should be deemed among the very first possible solution to try on. Just follow these steps:

  1. Tap Settings from your Home screen.
  2. Tap Cellular.
  3. If you’re using an eSIM on your iPhone, tap the line you are making changes to.
  4. Then tap the Cellular Data switch to turn the feature off for a few seconds then toggle again to turn it back on.

After restarting your iPhone’s cellular feature, soft reset the device to clear and refresh its internal memory. Then try placing a test call on your iPhone to your other phone (if available) and see if it’s already working.

Second solution: Use manual network selection on your iPhone X.

Normally, your iPhone automatically detects and registers on wireless networks within your carrier’s coverage area. But there are times when automatic network selections just doesn’t work while manual network selection does. Hence, give it a try and see if it aids you in resolving outgoing call problems on your iPhone X iOS 13. Just refer to these steps to make the changes:

  1. Tap Settings from your Home screen.
  2. Select Cellular.
  3. If you’re using an eSIM, tap the line you’re making the changes to.
  4. Then tap Network Selection to continue.
  5. Drag the Automatic slider to the OFF position. 
  6. Wait for your iPhone to scan for available networks.
  7. Select your carrier.

After making these changes, reboot your iPhone (soft reset). As soon as it’s finished rebooting, place a test call to see if it works.


Third solution: Use the Airplane mode trick to fix your iPhone X that cannot make phone calls in iOS 13.

A lot of people facing the same phone call dilemma on their iOS devices have found wonders from the so-called Airplane Mode trick. It works by simultaneously turning off the phone’s wireless features and then back on again. If you wish to take a chance, then you may do so through these steps:

  1. Tap Settings from the Home screen. 
  2. Select Airplane mode
  3. Toggle the switch next to Airplane mode to turn the feature on. All wireless functions of your phone are then disabled simultaneously.
  4. While the Airplane mode is enabled, perform a soft reset on your phone. 
  5. Wait until your phone is finished rebooting and then go back to Settings-> Airplane mode menu. 
  6. Finally, tap the Airplane Mode switch again to disable the feature again. 

Wireless connections are disabled if Airplane Mode is turned on so don’t forget to turn it off again.

Fourth solution: Reset network settings on your iPhone.

Network problems in general can also be remedied by resetting the network settings on your device. This will erase all your existing network settings and network configurations including APNs, Bluetooth connections and Wi-Fi networks. Any associated errors will also be cleared out in the process without affecting any saved information on the internal memory. Here’s how it’s done:

  1. From your Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap on Reset.
  4. Select Reset Network Settings from the given options.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to reset network settings on your device.

Your iPhone should restart when the reset is finished and then loads up its default network values and options. To get back online and use network features, you will need to re-enable them first. 


Fifth solution: Reinstall your SIM card.

Random SIM card errors can also halt incoming and outgoing call services on your device. To clear out random errors like this, reinstalling the SIM card is advised. Doing so will also allow you to reseat the SIM card in case it was dislodged from the tray. Just follow these steps:

  1. Turn off your iPhone to get started. This is recommended to prevent causing any sort of damage.
  2. While your iPhone is turned off, insert the SIM ejector tool into the small hole on the SIM tray located on the side of your device.
  3. Gently push the tool to eject the tray.
  4. Pull the tray out and then remove the SIM card. 
  5. Check the card for any possible damage indication such as scratches and liquid traces. If there’s none, place it back into the SIM card holder in the same orientation before you removed it.
  6. When the SIM card is secured, push the tray back into the phone until it clicks and locks.

Turn the phone back on and wait for it to re-establish network signal. When the signal gets stable, place a test call again and see if it’s already working.


Last resort: Erase your iPhone and restore its factory default settings.

Performing a full system reset may be necessary to eliminate complex network system flaws from the recent iOS 13 update installation. This will wipe everything out from your device and then restores its factory defaults. Backing up files from your iPhone storage is highly recommended so you’d still be able to recover them later. You can back them up to iCloud or iTunes, as you would prefer. If you wish to back up files to iCloud, then you can factory reset your iPhone X straight from settings. Just follow these steps:

Note: Back up your files if you haven’t already.

  1. From your Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap on Reset.
  4. Select Erase all contents and settings from the given options.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to factory reset on your phone.

Wait for your phone to finish resetting and then restarts when done. As soon as it boots up, use the start-up wizard to set your iPhone up as new and configure necessary features using automatic settings. 

Major system flaws are typically resolved after a factory reset unless the system gets totally corrupted or hardware damage is present. To fix a corrupt iOS, you can use iTunes to restore your iPhone X in recovery mode or DFU mode. A step-by-step walkthrough on how to restore an iPhone X in recovery mode and DFU mode can be found on this site’s tutorials page. Just visit the iPhone X troubleshooting page for more information.

Still having trouble with your iPhone X that cannot make phone calls in iOS 13?

If you ran out of options and your iPhone X is still unable to make phone calls, then you better report the problem to your service provider/carrier for further assistance. Ask them if there are any ongoing network outages that might have caused temporary downtime on cellular services, particularly outgoing calls. Also care to check on your account status. Account-related issues such as unsettled outstanding balances can also affect and/or cause temporary disruptions to outgoing cellular services. Thus, you need to settle any account problems as well. If you suspect that the problem is attributed to a damaged SIM card, then you can ask your carrier for a new SIM card replacement that’s provisioned with the same services you’re subscribed to.

For other recommendations, you may escalate the problem to Apple Support. Should this be found and confirmed to be an iOS 13 bug, Apple will be obliged to create the required patch.
