How do I fix No Service or a disconnected cell phone status?
Answer
No Service usually means the phone is not registered on the cellular network. A full restart and a short Airplane Mode toggle often restore the connection before deeper SIM or carrier steps are needed.
Before you start: stop right away if…
- Do not share passwords, recovery codes, or one-time codes with anyone who contacts you unexpectedly about restoring phone service.
Follow these steps
Power the phone off and on
Turn the phone completely off, wait about 30 seconds, then turn it back on and leave it on the home or lock screen.
You should see: The phone reboots and begins searching for the carrier network again.
Wait for network registration
Stay in one place with a clear signal if possible and wait about 5 minutes without rapidly toggling settings.
You should see: The No Service status clears, or signal bars and the carrier name return.
Toggle Airplane Mode
Turn Airplane Mode on for about 10 seconds, then turn it off and wait for cellular radios to reconnect.
You should see: The phone reconnects to the mobile network and can attempt a test call.
Confirm cellular is enabled
Open cellular or mobile network settings and make sure cellular service or mobile data is turned on. If your phone has Dual SIM, confirm the correct line is enabled for calls.
You should see: The active line shows as on, and the status bar no longer says No Service.

Extra tips
What to look for: A status bar or lock screen message such as No Service, No Signal, Searching, or Emergency calls only.
Before you change anything: Confirm whether Wi-Fi still works even when cellular service does not. Note your carrier name and whether the problem started after travel, a bill issue, or a SIM change. Avoid removing the SIM repeatedly or factory-resetting until simpler network steps fail. Never share account passwords or one-time codes with unexpected callers.
