12 Easy Fixes to Solve iPhone Call Failed Error

ByJim Miller

Phones were originally created to make and receive calls. However, iPhone users often encounter the frustrating “Call Failed” error when trying to make calls. If you're wondering why your iPhone is not letting you make calls, there could be several reasons behind it. In this article, we will cover all the possible solutions to fix the “Call Failed” issue on your iPhone. Let's dive in.

Restart Your iPhone

If you keep encountering the “Call Failed” error repeatedly, start the troubleshooting process by simply restarting your iPhone.

Dial a Secret Code

Sometimes, enabling the option to hide your caller ID on iPhone can lead to the “Call Failed” error. To disable this feature, dial a secret code: *#31#.

Check Your Plan

Make sure you have an active plan on your phone number. For postpaid users, ensure that you have paid your bill. If you are a prepaid customer, check if you have enough balance and validity.

Change Your Location

Poor network signal in your area can cause the “Call Failed” error. Try moving to a different location and then try making the call again.

Check Airplane Mode

Disable Airplane mode on your iPhone as it turns off all cellular services. If Airplane mode is enabled, you won't be able to make calls. Also, toggling Airplane mode on and off can help troubleshoot network problems.

Use the Right Network Operator

Manually selecting the wrong network operator can prevent you from making calls. Set your network selection to “Automatic” so that your iPhone automatically selects the correct network.

Use the Right Network Mode

Ensure that you have selected the correct network mode. If 2G is no longer supported in your area and your network mode is set to 2G, you won't be able to make calls. Try selecting different network modes to find the one that works.

Re-Insert Your SIM

Remove your SIM card from your iPhone, blow some air on it to remove dust, and then re-insert it. Sometimes, a loose connection can cause the “Call Failed” error.

Turn off Wi-Fi Calling

Disabling the Wi-Fi calling feature on your iPhone has helped many users fix the “Call Failed” issue. Go to Settings > Cellular/Mobile Data > Wi-Fi Calling and turn off the toggle.

Check for Carrier Update Settings

Network operators often send carrier settings updates to improve connectivity. Check for any available updates in Settings > General > About.

Update Your Software

Outdated software can also cause issues with making calls. Make sure to update your iPhone's software by going to Settings > General > Software Update. Updating your iPhone will also stop Siri from making calls on its own.

Reset Network Settings

If none of the above solutions work, reset your network settings. This will restore all network settings to default values. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset > Reset Network Settings.

These are the possible fixes for the “Call Failed” error on your iPhone. Hopefully, one of these solutions will resolve the issue for you. If you encounter any other network errors on your iPhone, check out our articles on fixing “No Service,” “SOS Only,” and other related issues.
