Samsung Galaxy • Connections • 5–15 minutes

No calls, texts, or phone signal — Samsung Galaxy

Safety firstIf only this Galaxy has no signal and the carrier says the line is active, contact the carrier before resetting or erasing anything.
If you need an urgent call and this Galaxy cannot connect, use another phone instead of continuing.

  1. Check for a software update

    Open Settings > Software update > Download and install. Follow the on-screen steps if one is available.

  2. Refresh the signal

    Open Settings > Connections and turn Airplane mode on. Wait 15 seconds, then turn it off.

  3. Make sure the SIM is on

    Open Settings > Connections > SIM manager. Turn on the switch beside your carrier line. Do not remove an eSIM.

  4. Make sure roaming is on

    Roaming lets the Galaxy use a partner network when your carrier’s own signal is unavailable. Open Settings > Connections > Mobile networks, then turn on Data roaming. Your carrier may charge for roaming outside your plan, especially internationally.

  5. Choose the network automatically

    Open Settings > Connections > Mobile networks > Network operators, then turn on Select automatically.

  6. Restart the Galaxy

    Hold the Side button and Volume Down, then tap Restart.
