    Fix the Call Failed Error on Your iPhone

    Ensure You Have Credits In Your Account

    Insufficient credits in your prepaid account can lead to the iPhone call failed error. You want to make sure your account has enough credits available for the call that you’re trying to place. You can recharge your account with various denominations to add credits to it.

    If yours is a postpaid account, you will want to talk to your provider to fix the issue.

    Ensure The Contact Is Not Blocked

    It may be that the contact you’re trying to call is blocked on your iPhone. You want to make sure the person is not on your block list, and you can verify it as follows.

    • Launch the Settings app on your iPhone.
    • Tap on Phone.
    Phone menu under Settings app
    • Select Call Blocking & Identification.

    • Turn the toggle for Airplane Mode to the ON position.

    • Tap on Phone.
    Phone tab under Settings

    • Tap on General.

    • When your iPhone is turned off, press and hold down the Power button to turn it back on.

    Close The Background Apps

    Most apps usually don’t interfere with the workings of the stock Phone app. However, you never know an app that you’ve installed on your iPhone can cause the issue. It’s worth closing all the apps on your phone to see if the issue persists.

    • Press the Home button twice to view the open apps list.
    • Swipe up the apps and they’ll be closed.

Fixing it should be easy and quick as all you need to do is remove it and put it back in. If there’s an issue with the card itself, you need to get it replaced by your provider.

    • Pull the SIM card tray out of your iPhone.
