How To Fix iPhone Call Failed Error

Apparently, the easiest and quickest way to solve it is by rebooting your device!

You can also try to cycle the Airplane Mode first, in the Control Center. Turn it ON for a couple of seconds and turn it back Off to force your device to connect to the nearest cellular tower.

Fact: Although your iPhone is displaying maximum signal strength the cellular coverage could’ve gone idle unexpectedly!

Tip: If the Airplane mode trick doesn’t help we recommend you to perform the force restart combo:

  • Click & release Volume Up, followed by Volume Down and press & hold the Side Button until the screen goes black and the Apple logo is displayed.
