Call Failed On IPhone? 13 Ways To Fix It

Are you struggling to fix the iPhone call failed error? This issue can be annoying, especially when making an important phone call. No matter what your iPhone version is, you want to get rid of it as soon as possible when it comes to any problem. Let's see how to fix it!

What Does a Call Fail Mean on iPhone?

The error occurs when you try to make a phone call, but your iPhone shows "call failed." The problem may appear when you're in the middle of a conversation.

When the iPhone is dropping calls, it is usually because the signal in a particular area is weak. Even though the poor signal is the most common reason for the issue, the SIM card could sometimes be the problem.

Quick Tips

• If the signal is poor, you may not be able to make calls. Consider getting a better reception.
• Turn Airplane mode Off.
• If your iPhone has a "No Service" Issue - Read this.
• Ensure that you have entered the number correctly. Try not to use the country code, such as starting with "00(country code)" or "+(country code)."

Ways To Fix The iPhone Call Failed Error

1. Toggle Airplane mode

Let's start with the easiest solution. Turn On Airplane mode by swiping down from the right area of the screen. Then, tap the Airplane icon in the upper-left corner. Wait for a few seconds, then turn it back off.

2. Change Date & Time

Check if the Date & Time on your phone are correctly set, especially if you have just traveled from a different time zone. Enabling "Set Automatically" is the best way to adjust this.

• Make sure your iPhone is connected to WiFi
• Next, go to Settings
• Tap General
• Select Date and Time
• Turn on "Set Automatically."

3. Dial *#31#

This is one of the iPhone's hidden codes to disable your outgoing anonymity status. Perhaps you have accidentally set your iPhone number to be hidden in all outgoing calls, and this causes call failure every time you make or receive a call.

Dialing *#31# is the fastest way to do this. You can also check it by opening

• Settings
• Tap Phone > Show My Caller ID
• Enable Show My Caller ID

4. Check your blocked contact list
