No network connection — Samsung Galaxy
Check for a software update
Why: A software update can repair the phone software that controls the SIM, Wi‑Fi, and Bluetooth.
What to do: Connect to any working Wi‑Fi network if one is available. Open Settings > Software update > Download and install. Follow the on-screen steps if an update appears. If no connection works, continue to step 2.
What to look for: After the Galaxy restarts, check whether the cellular bars, Wi‑Fi symbol, or Bluetooth device returns.
Turn Airplane mode off and refresh the radios
Why: Airplane mode turns off the Galaxy’s wireless connections, and toggling it can refresh a stuck connection.
What to do: Open Settings > Connections. If Airplane mode is on, turn it off. If it is already off, turn it on, wait 15 seconds, then turn it off again.
What to look for: Wait up to one minute for cellular bars, the Wi‑Fi symbol, or a Bluetooth connection to return.
Make sure mobile data is turned on
Why: Calls may still work while apps have no internet if Mobile data is off.
What to do: Open Settings > Connections > Data usage and turn on Mobile data. Then open Settings > Connections > SIM manager and make sure the switch beside your carrier line is on. Do not remove an eSIM.
What to look for: Confirm Mobile data and the carrier line remain on, then open a webpage with Wi‑Fi turned off.
Reconnect to Wi‑Fi
Why: A saved Wi‑Fi connection can stop working after its password or router settings change.
What to do: Open Settings > Connections > Wi‑Fi. Turn Wi‑Fi on, tap the network name, and enter its password if asked. If it says Connected without internet, test another Wi‑Fi network before changing the Galaxy.
What to look for: The network should say Connected and the Wi‑Fi symbol should appear at the top of the screen.
Turn Bluetooth on and reconnect one device
Why: Testing one known device shows whether Bluetooth itself is unavailable or only one accessory lost its pairing.
What to do: Open Settings > Connections > Bluetooth and turn Bluetooth on. Put one nearby accessory in pairing mode, then tap its name under Available devices.
What to look for: The accessory should appear under Paired devices and say Connected. If it does, Bluetooth is working even if another device still fails.
Restart the Galaxy
Why: Restarting reloads the wireless services without removing saved networks or accounts.
What to do: Hold the Side button and Volume Down, then tap Restart.
What to look for: After startup, wait one minute and check for cellular bars, the Wi‑Fi symbol, and Bluetooth again.
Reset network settings only as a last step
Why: This can repair damaged connection settings, but it removes saved Wi‑Fi networks and Bluetooth pairings.
What to do: Write down any Wi‑Fi passwords you need. Open Settings > General management > Reset > Reset Wi‑Fi and Bluetooth settings, then tap Reset settings and confirm. If mobile data still fails, return to Reset > Reset mobile network settings and confirm.
What to look for: Afterward, reconnect to Wi‑Fi and one Bluetooth device, then test mobile data again.
