If your iPhone is refusing to make calls and coming up with “Call Failed” error message, the problem could be due to change in call settings, poor network connectivity and other reasons.
While the “Call failed on iPhone” error message is known to prevent users from placing calls, it can also prevent others from calling your device.
Steps to Fix Call Failed Message on iPhone
You should be able to fix the problem of iPhone not connecting to calls and coming up with “Call Failed” message using the following troubleshooting steps.
1. Refresh Network
In many cases, the problem is due to a minor glitch preventing iPhone from connecting to Cellular network.
1. Open the Settings App on your iPhone.
2. On the next screen, enable Airplane Mode by moving the toggle to ON Position.
3. Wait for 30 seconds and disable Airplane Mode by moving the toggle to OFF position.
2. Unblock Phone Numbers
Sometimes, the problem is due to legitimate phone numbers getting accidentally blocked on iPhone.
1. Open Settings > scroll down and tap on Phone.
2. On the next screen, tap on Blocked Contacts.
3. On the next screen, see if the phone number that you are trying to Call is listed. If the phone number is listed, swipe-left on the blocked Phone Number and tap on Unblock.
Once the phone number is unblocked, you should have no problem receiving and making calls to this phone number from your device.
3. Enable Caller ID
In some cases, Hiding Caller ID can lead to “Call Failed” error on iPhone. This option can sometimes get enabled on iPhone due to accidental dialing of the code to Disable Caller ID.
1. Go to Settings > Phone > Show My Caller ID.
2. On the next screen, make sure that Enable Caller ID option is set to ON position.
Note: In general, hiding Caller ID should not prevent you from calling any phone number.
4. Remove and Re-insert SIM Card
An improperly inserted, faulty or damaged SIM Card is another reason for iPhone coming up with “Call Failed” error message.
Hence, remove the SIM Card from iPhone and inspect the SIM Card for visible signs of damage. If the SIM Card appears to be fine, reinsert the SIM Card and see if you can make a Call.
If your iPhone is still coming up with “Call Failed” message, insert the SIM Card into another iPhone and see if it is working.
If the SIM Card is not working on another iPhone, it confirms that the SIM Card is damaged and needs to be replaced.
5. Reset Network Settings
If above troubleshooting steps did not help, the problem could be due to Network Settings on your device becoming faulty or corrupted.
1. Go to Settings > General > Transfer or Reset iPhone > Reset.
2. On the pop-up, select Reset Network Settings option.
3. If prompted, enter your Lock Screen Password > On the confirmation pop-up, tap on Reset Network Settings to confirm.
After Network Settings Reset, you will be required to connect back to your WiFi Network by entering your Wi-Fi Network Password.
