Why Does My iPhone Keep Telling Me Call Failed?

If your iPhone keeps showing the “call failed” error, there could be various reasons behind it. Let’s break down some common causes:

  1. Poor Cellular Network: If you’re in an area with weak network coverage, your calls may fail to connect.
  2. SIM Card Problem: A malfunctioning SIM card can also prevent your iPhone from making calls properly.
  3. Incorrect Network Settings: Make sure your iPhone has the correct network settings. If they’re not updated or installed correctly, it can lead to call failures.
  4. Low/No Credit: Check if you have enough credit to make calls. Recharge your credit if it’s low or empty.
  5. Software Issues: Sometimes, updating your iPhone to a new iOS version can lead to call failed errors, although it’s rare.

By understanding these potential causes, you can troubleshoot the call failed on iPhone and hopefully restore smooth calling functionality.

How to Fix Calls Failed on iPhone?

Whatever the reasons, the following are some of the best ways that you can resolve this issue;

1. Try to Call Again

Before you can try to resolve any system issues or troubleshoot the Phone app in any way, it is a good idea to try to place the call again. Sometimes a network glitch beyond your control could be causing the issue and simply trying again will do the trick.

2. Dail *#31#

One of the most reliable and simplest ways to fix the issue of  call failed on iPhone is to dial *#31#. This code helps to reset the call settings and can resolve various calling problems.
When you dial *#31#, you are essentially disabling the Caller ID feature temporarily. Caller ID allows your phone number to be displayed to the person you are calling. By disabling it, you are resetting the call settings, which can help to address any potential configuration issues related to Caller ID or the network settings.
In some cases, “call failed” errors may be caused by conflicts with the network or improper configuration settings. Dialing *#31# forces the phone to re-establish the calling connection with a fresh configuration, often resolving the problem and allowing you to make successful calls again.
Keep in mind that this method may not be effective for all “call failed” issues, as there can be other underlying causes. If the problem persists, you may need to explore other troubleshooting steps or contact your carrier for further assistance.

3. Toggle Airplane Mode On and Off

Any network errors on your iPhone can be resolved by forcing the device to refresh the connection. One of the best ways to do that is to enable Airplane mode and then disable it. Here’s how you can do that very easily;

  • Access the Control Center on your device. You can do that by either swiping down from the top right of the screen or up from the bottom for older models.
  • Tap on the airplane icon to enable Airplane mode.
  • Then tap on the same icon again to disable it and force the device to connect to all networks.

4. Check Your Blocked Contact List

iPhone call failed may also occur if the contact you are attempting to call is blocked. To check this, go to Settings > Phone > Blocked Contacts and if the contact is on this list, tap on it to remove it.

5. Disable Call Blocking

To prevent this “call failed” message for all contacts in the future, you can disable call blocking completely.

To do that, tap on the Settings app icon on your iPhone and select “Phone.” Select “Call Blocking & Identification” and check if the switch next to “Allow These Apps to Block Calls and Provide Caller ID” is turned on. If it is, turn it off to disable call blocking.

6. Change the Date & Time

Incorrect date and time settings can also affect calls, particularly if you had just traveled to a different time zone. The best solution is to ensure that “Set Automatically” is enabled in the settings.

Just go to Settings > General > Date & Time and turn on the switch next to “Set Automatically.”

7. Restart Your iPhone

If you still can’t make a phone call after trying the solutions above, restarting the iPhone may help remove any system bugs and errors affecting the Phone app.

You can restart the device in the Settings app by simply going to Settings > General > Shut Down. Wait a minute or two and turn on the iPhone again to see if you can make a phone call.

8. Disable LTE

Although LTE can enable your iPhone to connect to the internet faster, sometimes it can also affect the phone calls. You can go to Settings > Cellular > Cellular Data > Voice & Data and choose “3G” to rule out LTE as the main cause.

9. Remove & Reinsert the SIM Card

You may also want to check if there is a problem with the SIM card and the only way to do that is to remove the SIM card.

Open the SIM Tray on your iPhone using the SIM ejector tool. Check for any signs of obvious damage on the surface of the SIM card. If it is not damaged, place it back on the tray and push the SIM tray in place.

But if the SIM card has any signs of damage, contact your phone carrier to get it replaced.

10. Reset Network Settings

Since this problem is often caused by a network connectivity issue, resetting the network settings is one of the best ways to fix it. Please note that this solution will not affect any of the data on your iPhone, but it will erase connections such as saved Wi-Fi networks, Bluetooth devices, and VPN settings.

To reset the network settings, go to Settings > General > Reset > Reset Network Settings and enter your iPhone passcode when prompted.

When your device restarts after the reset, you can try to make the phone call again.

Open Settings > General > About and if there is an update, a popup will appear. Tap “Update” to install the new updates.

14. Contact Your Phone Carrier
