How to fix called failed on iPhone

Is there anything more frustrating than attempting to make a phone call on your iPhone, only to be met with the dreaded “Call Failed” message? This common issue can be caused by a variety of factors, ranging from network problems to software glitches. However, fear not! In this comprehensive guide, we will walk you through the step-by-step process to diagnose and find out how to fix called failed on iPhone. By the end of this article, you’ll be equipped with the knowledge to tackle this problem and regain seamless calling functionality on your device.

How to fix called failed on iPhone

Section 1: Check Network Connection

The first step in resolving the “Call Failed” issue is to verify your network connection. Ensure that you have adequate cellular signal strength or are connected to a stable Wi-Fi network. If you notice poor signal strength, try moving to an area with better coverage or switch to Wi-Fi to rule out network-related problems.

Section 2: Restart Your iPhone

A simple yet effective troubleshooting step is to restart your iPhone. Sometimes, temporary glitches or minor software hiccups can cause call failures. To do this, press and hold the power button until the “slide to power off” slider appears. Slide it to turn off your iPhone, then press and hold the power button again to turn it back on.

Section 3: Check Airplane Mode and Do Not Disturb Settings

Make sure that Airplane Mode is turned off and that your iPhone is not set to Do Not Disturb mode. Airplane Mode disables all wireless connections, while Do Not Disturb blocks incoming calls and notifications. These settings can be accidentally activated, leading to call failures.

Section 4: Update iOS

Outdated software can lead to compatibility issues and glitches. To ensure your iPhone is running smoothly, check for any available iOS updates. Go to “Settings” > “General” > “Software Update” to see if a new version is available. If one is found, download and install it to fix potential bugs.

Section 5: Reset Network Settings

Resetting your network settings can often resolve connectivity-related issues. To do this, go to “Settings” > “General” > “Reset” > “Reset Network Settings.” Keep in mind that this action will erase saved Wi-Fi passwords and VPN settings, so you may need to re-enter them after the reset.

Section 6: Check Call Forwarding and Call Blocking Settings

Improperly configured call forwarding or call blocking settings can interfere with your ability to make calls. Go to “Settings” > “Phone” > “Call Forwarding” and “Settings” > “Phone” > “Call Blocking & Identification” to ensure that these settings are configured correctly.

Section 7: Remove and Reinsert SIM Card

Occasionally, a loose or damaged SIM card can cause call failures. Power off your iPhone, locate the SIM card tray (usually found on the side or top of the device), eject the SIM card using a paperclip or SIM ejector tool, and then reinsert it firmly. Turn your iPhone back on and see if the issue persists.

Section 8: Clear Phone App Cache

The Phone app’s cache can sometimes become corrupted, leading to call-related problems. Unfortunately, iOS doesn’t provide a direct way to clear the cache for specific apps. However, you can try deleting the app and reinstalling it from the App Store to refresh the cache.

Section 9: Contact Carrier Support

If you have tried all the troubleshooting steps above and are still experiencing “Call Failed” issues, it’s possible that the problem lies with your carrier. Reach out to your carrier’s customer support to check if there are any network outages or known issues in your area.

Section 10: Check for Carrier Settings Updates

Carrier settings updates are small files provided by your carrier that contain important settings, including network settings, for your iPhone. Sometimes, outdated carrier settings can lead to calling issues. To check for updates, go to “Settings” > “General” > “About.” If a carrier update is available, you’ll receive a prompt to install it. Follow the instructions to update your carrier settings.

Section 11: Disable Wi-Fi Calling

Wi-Fi Calling can be a useful feature, especially in areas with weak cellular signal but a strong Wi-Fi connection. However, it may also cause calling problems if not set up correctly. To troubleshoot, disable Wi-Fi Calling temporarily. Go to “Settings” > “Phone” > “Wi-Fi Calling” and toggle the feature off. Attempt to make a call using cellular data, and if the issue is resolved, there might be an issue with your Wi-Fi Calling settings or network.

Section 12: Factory Reset Your iPhone

If all else fails and you’re still encountering the “Call Failed” error, you may consider performing a factory reset on your iPhone. This process erases all data and settings on your device, so make sure to back up your important data first. To perform a factory reset, go to “Settings” > “General” > “Reset” > “Erase All Content and Settings.” Follow the prompts to erase your iPhone and set it up as new. Afterward, check if the call issue persists.

Section 13: Seek Professional Help

If you have exhausted all troubleshooting options and the “Call Failed” problem remains unresolved, it might be time to seek professional assistance. Reach out to Apple Support or visit an Apple Store to get your iPhone thoroughly checked and, if necessary, repaired or replaced. Remember to bring all necessary documents and your device’s warranty information for a smoother experience.


Experiencing “Call Failed” errors on your iPhone can be incredibly frustrating, but with the steps outlined in this guide, you can troubleshoot and fix the problem on your own. By verifying your network connection, checking settings, updating software, and performing necessary resets, you can address various potential causes of the issue.

If the problem persists after trying all the steps mentioned above, it might indicate a hardware problem. In such cases, it’s advisable to seek assistance from an Apple Store or an authorized service provider for further diagnosis and repair. With persistence and a methodical approach, you can overcome the “Call Failed” issue and enjoy uninterrupted calling on your iPhone once again.
