Go to Settings > Connections > Mobile Networks and ensure:

Network Mode matches your carrier's requirements (e.g., 4G/3G/2G).

Access Point Names (APNs) are correctly configured for your carrier.


Try selecting your network manually: Settings > Connections > Mobile Networks > Network Operators > Search Networks.

Turn Off the Device: Press and hold the Power button until the power menu appears, then tap Power Off.


2. Boot into Safe Mode:

Press and hold the Power button until the Samsung logo appears.

Release the Power button and immediately press and hold the Volume Down button.

Keep holding the Volume Down button until the home screen appears.

You’ll see “Safe Mode” displayed in the bottom-left corner.
