Why does an iPhone show Call Failed after it shut down during a call?
Answer
Restart the iPhone, toggle Airplane Mode, and confirm the cellular line is on. Call Failed after a sudden shutdown often clears after the phone re-registers on the network.
Before you start: stop right away if…
- Repeated shutdowns with a charged battery can indicate a hardware issue.
- Do not share account PINs with unsolicited carrier callers.

Restart the iPhone
Power off fully, wait 30 seconds, turn on, then try a call.
You should see: Calls connect or status is clearer.
Reset the cellular radio
Turn Airplane Mode on for 15 seconds, then off, and wait for signal.
You should see: The carrier name returns and a test call works.
Confirm the line is active
