  • From Settings: Touch Settings from iPhone home screen and tap the button next to Airplane Mode to green at the top of the Settings window for a moment. Then, turn it off.

Close All Running Apps

Are you opening too much apps in the background? If yes, do shut off all of them as they might cause glitches and interfere with your iPhone calling process.

  • On an iPhone X or later, swipe up from the bottom of the screen to open the app switcher. On an iPhone 8 or earlier, double-press the Home button to start the app switcher.

Dial *#31# to Disable Calling Line ID Restriction and Show Caller ID

Tips: *#31# is a secret code on smartphone that allows users to hide their number when phoning someone.

A failed call in iPhone could also be the result of call anonymity. To see if your phone number identity is hidden when making outgoing calls, dial *#31# to check your status. If you're prompted with a pop-up stating that "Setting Interrogation Succeeded Calling Line ID Restriction Disabled", your Caller ID has been disabled. For that, you're required to activate the Caller ID by entering *#31# again. Alternatively, navigate through Settings > Phone > Show My Caller ID to switch the slider to ON.
