How do I fix Not registered on a network on a Samsung phone with autopay?
Answer
Toggle Airplane Mode, restart the phone, then reset mobile network settings if needed; if the account is paid up, contact the carrier because autopay alone does not guarantee the SIM or line is provisioned.
Before you start: stop right away if…
- Resetting network settings removes saved Wi‑Fi networks and Bluetooth pairings on many phones.
Follow these steps
Toggle Airplane Mode
Turn Airplane Mode on for about 5 seconds, then turn it off and wait for the phone to reacquire a network.
You should see: Carrier signal returns, or the not-registered message remains.
Restart the phone
Power the Galaxy phone completely off, wait a few seconds, and turn it back on.
You should see: The phone re-registers to the network after reboot.
Reset mobile network settings
Go to Settings > General management > Reset and choose Reset mobile network settings or Reset network settings, then rejoin Wi‑Fi afterward if needed.
You should see: Cellular registration succeeds after the reset.
Contact the carrier if still unregistered
Call the carrier with the phone number and ask them to verify the line status and refresh provisioning, mentioning that autopay is enabled but the handset still shows not registered.
You should see: The carrier repairs the line status or identifies a SIM/account issue.

Extra tips
What to look for: Not registered on a network status, signal bars missing, SIM detected in status settings, and whether autopay recently failed despite being enabled
Before you change anything: Confirm the SIM or eSIM is for the active carrier line. Note any recent phone or plan changes. Resetting network settings forgets Wi‑Fi passwords. Do not share account codes with unexpected callers.
