You might be wondering how you can make your calls go through and what you need to do to fix your mobile device. We have some great solutions for this problem here. So, keep reading!

Part 1. How to Stop iPhone from Keeping Saying Call Failed

Your iPhone calls can fail when your cellular network is down, the wifi is down, or your phone is glitching. Look at these quick fixes to get your device back in working order.

1. Check Blocked Phone Numbers

In some cases, it isn't your device's fault that the iPhone call failed to one number. If you accidentally blocked a phone number, then the call won’t go through. These steps should be used to check blocked phone numbers:

Go to Settings > Phone. Press the option that says Blocked Contacts.

Look at the phone numbers that are blocked.

If the phone number you are trying to call is on the list, unblock it.

2. Turn Airplane Mode On and Off

If your phone is in airplane mode, then your calls won't go through. And in some cases, just putting your phone in airplane mode and then turning it off can help resolve internet issues.

On your iPhone, swipe down. This will open your control center.

In your control center, press the airplane icon.

Click the icon so it’s blue. Click the icon again so it's gray.

Airplane mode should be turned off now and you can make a call.

3. Turn Call Forwarding Off

Another way you can fix a new iPhone call failed is by changing your phone settings. When you have this setting on, it will forward calls to a different phone number. This is why you get a call failed message. Turning off your call forwarding will stop your phone from interfering with your calls.

Go into your Settings > Phone, scroll down to Call Forwarding.

Press the switch next to Call Forwarding and turn this setting off.

4. Check Call Blocking Settings

You can also tweak other settings in your phone to deal with iPhone call failure. Turn off your Call Blocking to prevent more call failures. Sometimes Apple will block certain numbers they think are spam or fraudulent. You can do this by:

Go to your Settings app. Scroll down to Phone setting.

In Phone Settings press on Call Blocking and Identification.

From here, you can check the blocked phone number.

5. Turn Off LTE

LTE can get slow at times, even though it’s meant to give you lightning-fast data and service. Turn off this feature if your iPhone keeps saying call failed. You can use your WiFi or cellular network to make the call instead.

Enter your Settings > Cellular. Click on Cellular Data Options.

Scroll down to LTE. Check the Off option to turn off LTE.

6. Remove All Apps Running in the Background

Other background apps can interfere with your phone calls and even your network reception. Make sure that you're removing all your running apps in the background to make your iPhone call go through. To clear any background apps do this:

Put your finger near the bottom of your screen. Swipe up in this area.

Apps that are running will pop up. Swipe up on them to remove your running apps.

7. Remove & Re-insert Your SIM Card

There could be an issue with your SIM card or your phone network. Try to take the SIM card out of your iPhone. Then put it back into your device so you can make your call again.

Get an ejector tool or a small paper clip. Place your tool into the SIM card slot.

Press in till the slot opens up. Take out your SIM card gently. Then place it back in and close the SIM slot.
