? Why Does “Call Failed” Happen on iPhone?

Before jumping into the fixes, it’s essential to understand why your iPhone might display a “call failed” error. Here are some of the most common reasons:

• Weak Network Signal – If you’re in an area with poor cellular reception, your calls may fail.

• Software Glitches – Bugs in iOS can interfere with call functionality.
• Blocked Contacts – If you’ve blocked a number, you won’t be able to call them.
• SIM Card Issues – A loose, damaged, or improperly inserted SIM card can cause call failures.
• Incorrect Network Settings – Changing network settings or incorrect APN settings can lead to connectivity problems.
• Outdated Carrier Settings – If your carrier settings are outdated, your iPhone may struggle to connect to the network.

Now that we understand the causes, let’s explore how to fix the “call failed iPhone” issue.

? How to Fix “Call Failed” on iPhone

1. Check Your Signal Strength

Poor network reception is a leading cause of call failures. Here’s how to check and improve your signal strength:

• Look at the signal bars on the top right of your screen. If they’re low or missing, move to an open area.
• If you’re indoors, step outside or near a window to get a stronger signal.
• Switch between Wi-Fi Calling and Cellular Network (Settings ? Phone ? Wi-Fi Calling).

If your signal strength is still weak, try restarting your phone or switching to another network.

2. Turn Airplane Mode On and Off

Toggling Airplane Mode can quickly reset your network connection:

1. Open Control Center (swipe down from the top-right corner on newer iPhones).
2. Tap the Airplane Mode icon to enable it.
3. Wait 30 seconds and then disable it.

This action forces your iPhone to reconnect to the network, which can resolve minor call issues.

3. Restart Your iPhone

A simple restart can fix various software glitches that cause the “call failed iPhone” problem.

• For iPhone X and later: Press and hold the Side Button + Volume Down until the power-off slider appears. Slide to turn off, then turn it back on after 30 seconds.
• For iPhone 8 and earlier: Press and hold the Power button, slide to power off, and restart after 30 seconds.

4. Check If the Number is Blocked

If the issue occurs when calling a specific contact, check if they are blocked:

1. Open Settings ? Phone ? Blocked Contacts.
2. If the number is listed, swipe left and tap Unblock.

5. Remove and Reinsert Your SIM Card

A loose or improperly inserted SIM card can cause call failures. Follow these steps:

1. Turn off your iPhone.
2. Use a SIM ejector tool (or a paperclip) to remove the SIM card.
3. Clean the SIM card gently and reinsert it properly.
4. Turn on your iPhone and check if the issue persists.

6. Reset Network Settings

Incorrect network settings can cause connectivity issues. Resetting them can fix the problem:

1. Open Settings ? General.
2. Scroll down to Transfer or Reset iPhone ? Reset.
3. Tap Reset Network Settings and enter your passcode.
4. Restart your iPhone and check if calls work.

?? Note: This will erase saved Wi-Fi passwords, so make sure to reconnect afterward.

7. Check for Carrier Updates

Your iPhone needs the latest carrier settings to function correctly. Here’s how to check for updates:

1. Open Settings ? General ? About.
2. Wait a few seconds. If an update is available, a prompt will appear.
3. Tap Update to install the new carrier settings.

8. Update iOS to the Latest Version

Apple regularly releases software updates to fix bugs. If your iPhone is running an outdated iOS version, update it:

1. Open Settings ? General ? Software Update.
2. If an update is available, tap Download and Install.
3. Restart your iPhone and test if calls work properly.

9. Disable Call Forwarding

If call forwarding is enabled, incoming calls might not connect properly:

1. Go to Settings ? Phone ? Call Forwarding.
2. If it’s turned on, disable it.

This ensures your calls route correctly without interruptions.

10. Contact Your Carrier

If none of the above fixes work, your mobile carrier might be experiencing issues. Contact them and ask about:

• Network outages in your area
• Account-related restrictions (e.g., unpaid bills)
• SIM card activation issues

Your carrier may also provide a replacement SIM card if necessary.
