Solutions to ‘Call Failed’ Issue

Solution  1: Toggle your iPhone into Airplane Mode

Toggle your iPhone into Airplane Mode

So the first thing to do is to toggle your phone into Airplane Mode. This is the easiest solution as you can easily access it from the control center and the settings.

Here how you access Airplane Mode:

  • Turn on the Airplane Mode by swiping up from the control panel
  • Wait a few seconds and turn it back off

Here’s another way:

Turning Airplane mode on and then off can fix some call issues and this may help solve the call failed error message.

Solution 2: Change the Date & Time of your Device

The next thing you can do is to change the date and time of your device.

This may be a weird solution but it can fix some issues with your calls.

This might sound funny, but it works when you tamper with Date & Time in your iPhone. Well, as a matter of fact, you don’t actually have to interfere with date and time; follow the steps.

Solution 3: Dial *#31#

Dial *#31#

The next thing that could help you with this problem is to dial *31#.

This is one of the hidden codes on your iPhone which will allow you to disable your outgoing calls on anonymity status.

So, if you’ve placed your iPhone number on hidden, dialling this code would fix a problem which could have caused the call failed issue in the first place.

You can also check these settings without dialling the number. Here’s how you do it:

  • Go to settings
  • Scroll down to your apps and click Phone
  • In here, click toggle on Show My Caller ID and make sure it’s set to green

This is usually the main tip that stops the issue so be sure to use it.

Solution 4: Tray Problem

The most common reason for this error is that your SIM card has been damaged or it’s not properly placed on the SIM tray.

To fix this,

  • Open the SIM tray
  • Remove the SIM card.
  • Make sure the tray is clean and the port where you insert the SIM is clean.
  • Put the SIM back in.

This will restart your SIM which will fix the problem. Also, If there’s like dust and dirt inside, this can result in your phone dropping calls.

Solution 5: Restart your iPhone

If the last tip didn’t help you, you’ve got to restart your iPhone. It’s one of the simplest solutions but it fixes so many issues with your iPhone. If you have any problem with your iPhone, always restart it and check if the problem has gone.

Here’s how you restart your device:

  • Hold the home and the lock screen button for about 20 seconds
  • Wait for your iPhone to turn back on

This should fix the problem in most cases.

Solution 6: Change the Carrier Settings Update

First of all, you need to make sure your SIM card is inserted in your phone and you have a signal.

If you call them and tell them that there’s an issue with your calls, they will give you ways to troubleshoot the problem.

Solution 9: Update your iOS to the Latest version

Another step would be updating your iPhone to the latest software. This can help solve some software issues within your device. If you’re on an old version of iOS, you definitely need to update your iPhone if these steps above didn’t work.

update iOS

  • Go to Settings
  • Go to General
  • Tap Software Update

Make sure there’s no software update shown. If so, update your iPhone.

When updating your device, make sure your iPhone is on 50% battery and make sure it’s connected to Wi-Fi otherwise it won’t update.

Solution 10: Reset your iPhone Settings

If none of the above steps has helped, you need to reset your iPhone.

reset all settings

Make sure that you click Reset all Settings instead of Reset all Content and Settings. If you just reset your settings, your personal data won’t be deleted.

You can do that by:

  • Going to Settings
  • Tap General
  • Tap Reset all Settings
  • Enter your passcode

This should solve the iPhone call failed issue but if it does not then scroll down.

Solution 11: Close Unnecessary Apps

Close Unnecessary Apps

Some users have the habit of keeping so many apps open simultaneously. This, of course, drains your memory and results into call failing. A smart user will never do this. Close unnecessary apps on your iPhone by double pressing home button and swipe up the apps. Agreed that your phone is latest and boasts many powerful features, but it is always wise to save some memory.

Solution 12 : Caller ID

Caller ID option is subject to the mobile service provider you have opted for. Hence, this might not work on all iPhones; you can still take a chance.

  • Go to Settings and tap on Phone
  • Now tap on Show My Caller ID and toggle it caller id on

If this fails to work, you can also turn off Call Forwarding and Call Waiting options.

Solution 13: Erase your Whole iPhone

If resetting your iPhone didn’t help, there’s only one thing you can really do which is to erase your whole iPhone.

This is the worst-case scenario. If there’s something really wrong with your system, this should fix the problem and fix the call failed error message.

However, this is not a solution I recommend because it will erase all your data. Before using this step, make sure your device is backed up.
erase content and settings

  • Go to Settings
  • Go to General
  • Tap Reset
  • Hit Erase all Content and Settings

Note that this will erase your entire phone and nothing will be left. It will be a brand new iPhone after.

Solution 14: Repair your iPhone

Repair your iPhone

The last option is to get your iPhone repaired because the antenna inside your iPhone could be damaged and the only way to fix it properly is to get it repaired.

Going to the Apple store is the best option for this.

That is how you can fix a call failed error on iOS. If you’re still having this issue, comment down below your exact problem and I’ll help you further.
