Olanrewaju Sodiq

You pick up your iPhone and dial a number or contact on your phonebook. The call doesn’t go through, and there’s a Call Failed error message on your screen. You try again but get the same error. Why is this happening? And what could be responsible for the malfunction? We explain everything in this guide.

It is also common to have this error message pop up in the middle of an ongoing conversation. This issue is usually due to poor signal strength in your location. Other system configurations and call settings could also be responsible for the Call Failed error. Luckily, you can easily get this fixed on your own. We’re certain that at least one of the solutions listed below would get you back to making uninterrupted calls on your iPhone. Check them out.

1. Use Airplane Mode

Simply toggling on Airplane mode on your iPhone (or iPad) and flicking it back off after some seconds can work the magic. I have used this method a couple of time, and it works. You should try it too. Open your iPhone's Control Center and tap the airplane icon. Wait a couple of seconds and tap the icon again to turn off Airplane Mode.

2. Unhide Caller ID

Having your iPhone's caller ID hidden is another reason why outgoing calls sometimes fail. If you encounter the Call Failed error often, check that your caller ID is visible. A quick way to unhide your caller ID on iOS devices is to dial the *#31# code in the Phone app. That will make your caller ID visible and fix the Called Failed error.

3. Unblock Contact

You might encounter the Call Failed error if you call a number you've blocked. If you only get the error message when calling a particular number, there’s a chance that you can’t get through to the person because they’ve been blocked. The best move, in this case, would be to check your iPhone's Blocked Contacts list.

Step 1: Go to Settings and select Phone.

4. Disable Call Forwarding

This is another solution that many affected users have pronounced an effective fix to the Call Failed error. Asides this issue, call forwarding is also responsible for other call-related malfunctions on your iPhone. Navigate to Settings > Phone > Call Forwarding and check that the option is toggled off.

5. Restart Device

If the error persists after trying all the above, restarting your iPhone might work as a solution. For iPhone X and newer generations, tap and hold the power button and either volume button until the Power Off slider appears on your screen. For older generations of iPhones (iPhone 8 or older), they simply hold the power button for about 3 seconds until the slider comes on screen.

Move the slider to the right to power off your device. Wait for a couple of seconds and turn your iPhone back on.

6. Reinsert SIM Card

If restarting your phone yields no positive result, another thing you can do to resolve this issue is to eject and reinsert your SIM card to your phone. We recommend cleaning the SIM card's contact panel with a dry cloth before reinserting to your iPhone.

7. Reset Network Settings

This is another proven fix for this issue. This guide will walk you through the entire process of getting this done, plus every other thing there is to know about resetting your iPhone's network settings. Do take a minute to check it out.

Tip: Navigate to Settings > General > Reset > Reset Network Settings to reset your iPhone's network settings. You'll also be prompted to input your phone's passcode.

8. Update iOS

Running an outdated, buggy, or corrupt iOS version on your iPhone could also be responsible for this error. If nothing solves the error, updating your iPhone to the latest iOS version could help. To do this, go to Settings > General > Software Update and install updates in the section.

Check With Your Carrier

The iPhone's Call Failed error could sometimes be due to connectivity issues on your carrier's end. Likewise, you could encounter this error if your carrier has disconnected your phone due to outstanding phone bills.
