We are sure that at least one of the solutions listed below will allow you to make calls on your iPhone.
1. Use Airplane mode
Simply activating Airplane Mode on your iPhone (or iPad) and turning it off after a few seconds can do the magic. I've used this method a couple of times 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.
Alternatively, launch the iOS settings menu, turn on Airplane Mode and turn it off. If you still see the error message Call failed, move on to the next solution.
2. Find out the caller ID
Having your iPhone caller ID hidden is another reason why outgoing calls are sometimes not made. If the Call Failed error occurs frequently, verify that the Caller ID is visible. A quick way to find out caller ID on iOS devices is to dial the code * # 31 # in the Phone app. This will make your caller ID visible and resolve the Call Failed error on iPhone.
You can also change the visibility status of your iPhone's caller ID in the iOS settings menu. Follow the steps below to do this.
Step 1: launch the Settings app and select Phone.
Step 2: tap "Show Caller ID".
Step 3: check that the “Show Caller ID” option is enabled.
3. Unblock the contact
You may encounter the Call Failed error if you call a number that you have blocked. If you only get the error message when calling a certain number, it's possible that you can't get in touch with 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.
Step 2: Scroll to the bottom of the Phone menu and select Blocked contacts.
Step 3: select Edit and then touch the icon with the red minus sign to remove a contact from the list of blocked contacts.
Step 4: Then select Unblock.
Another way around this is to open your contact information and select Unblock Contact.
4. Disable call forwarding
This is another solution that many interested users have called an effective solution to the call failed error. Apart from this issue, call forwarding is also responsible for other call related malfunctions on your iPhone. Go to Settings> Phone> Call Forwarding and make sure the option is off.
5. Restart your device
If the error persists after trying all of the above, restarting your iPhone may work as a solution. For iPhone X and newer generations, touch and hold the power button and one of the volume buttons until the power off slider appears on the screen. For older iPhone generations (iPhone 8 or earlier), simply press and hold the power button for about 3 seconds until the cursor appears on the screen.
Move the slider to the right to turn off the device. Wait a couple of seconds and turn your iPhone back on.
6. Reinsert the SIM card
If restarting the phone does not produce positive results, another thing you can do to fix this is to remove and reinsert the SIM card into the phone. It is recommended to clean the SIM card contact panel with a dry cloth before reinserting it into the iPhone.

This is another solution to try to solve this problem. This guide will walk you through the entire process to do this.
Suggestion: Go to Settings> General> Reset> Reset Network Settings to reset your iPhone's network settings. You will also be asked to enter your phone passcode.
