Method 4 – Check Your SIM Card

Experts state that if you are not able to call any number from your iPhone then there could be an issue with your SIM card. This method is not applicable to users with an eSIM facility. Remove your SIM card using the SIM ejection needle or a paper clip and check the SIM card physically. If you find that the SIM card has been damaged then you need to take it to your carrier’s service center to replace it.

Also, you can try using the current SIM card in another phone to find out if the problem lies with the physical SIM card. If it works fine in another phone then place it back in your iPhone and check. If it is still not working then there could be a problem with your iPhone’s SIM tray or slot. In this case you will have to visit the iPhone service center to get your device checked.

Method 5 – Reset Network Settings

The iPhone call failed issue can also occur due to Network settings. Experts suggest that you reset the network settings to improve the connection. It is an easy task to reset the network settings on iPhone and here is what you need to do.

Tap on Settings -> General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings.

Method 6 – Activate Airplane Mode

This is a simple yet effective trick that has worked for  many users. All you have to do is toggle on the Airplane Mode option and then toggle it off. In other words, you need to enable the Airplane mode for a few seconds and then disable it.

  • To do this, you need to swipe down the home screen and open Control Center.
  • Tap once on the Airplane icon to enable this mode.
  • Wait for a few seconds and tap again on the same icon to disable this mode.
  • Once your phone connects to the default network, try making the call again.

Method 7 – Verify The Status Of the Focus Mode & Do Not Disturb Mode

Apple has inculcated many features in iPhone and there are a few features that minimize distractions of the users. One such feature is the Focus Mode and another is Do Not Disturb. If any of these features are enabled then you will not be able to make calls and get the iPhone call failed error.

Method 9 – Disable Wi-Fi Calling

Turning off Wi-Fi Calling can also help resolve the “Call Failed” error on your iPhone, as this issue may sometimes be related to problems with your internet connection. When you disable Wi-Fi Calling, calls will be routed through the mobile network instead, which could fix the problem. To do this, go to Settings -> Cellular, then tap Wi-Fi Calling and toggle off Wi-Fi Calling on This iPhone.

Method 10 – Turn On Automatic Network Selection

The “Call Failed” error on your iPhone can also be caused by a weak or overloaded cellular network. Enabling automatic network selection can help resolve this issue by allowing your iPhone to switch to a different network if the current one isn’t functioning properly. To enable this feature, go to Settings -> Cellular, tap Network Selection, and toggle Automatic on.

If automatic network selection is already turned on, try disabling it and manually selecting a mobile network to see if that helps fix the problem.

Method 11 – Choose The Correct Network Mode

The “Call Failed” error can also happen if your iPhone is connected to the wrong network mode. For instance, if your iPhone is set to 5G but you’re in an area with only 4G coverage, you may encounter this issue. To avoid this, make sure to select the correct network mode. Here’s how to do it:

  • Go to Settings -> Cellular.
  • Tap Cellular Data Options -> Voice & Data.

  • Choose 5G or another network mode supported by your SIM.
  • If you’re on 3G, you may want to disable VoLTE to improve connectivity

Method 12 – Factory Reset

If none of the previous solutions have worked, performing a factory reset on your iPhone may be your final option. This will erase all user data and settings, restoring your iPhone to its original factory state and potentially fixing any underlying issues.

Note – Since a factory reset deletes all photos, videos, files, and settings, it’s crucial to back up your iPhone beforehand to avoid losing your data permanently. To perform a factory reset:

  • Go to Settings → General → Transfer or Reset iPhone.
  • Select Erase All Content and Settings.

  • Tap Continue and enter your iPhone passcode.

Wait for the automatic iCloud backup to finish, then follow the on-screen instructions to finish resetting your iPhone.

Method 13 – Contact Apple Support

If none of the solutions above resolve your issue, it’s time to reach out to Apple Support or other relevant support services for further assistance.
