Can I use WLAN while Airplane mode is on?

On most Samsung phones yes. Turn on Airplane mode in Settings ➔ Connections, then enable WLAN separately from the same screen or the quick panel.

Does Airplane mode affect the SIM registration?

Yes, the phone deregisters from the mobile network while Airplane mode is active. After you disable it, the SIM needs a moment to reconnect before calls and data work again.

Why do calls still fail after I turn Airplane mode off?

A weak signal area or a delayed SIM reconnection can cause this. Restart the phone or briefly toggle Airplane mode on and off again from Settings ➔ Connections.

Samsung: Turn Airplane Mode On or Off

When Airplane mode stays on longer than planned, your Samsung phone drops calls, texts and every network link, including mobile data, WLAN and Bluetooth. Some models let you switch WLAN and Bluetooth back on while flight mode stays active, others keep everything locked until you disable it fully. Knowing which toggle actually restores connectivity saves time at the gate or in a signal-free area.

Turn Airplane Mode On or Off auf Samsung

Airplane mode on a Samsung phone cuts the connection to the mobile network in one step. Calls, texts and mobile data stop working right away, and depending on the model, WLAN and Bluetooth switch off along with them.

The toggle sits inside the connectivity settings, not only in the quick panel. Open Settings ➔ Connections ➔ Enable or disable Airplane mode to switch the function on or off directly.

On many Samsung phones you can turn WLAN and Bluetooth back on while Airplane mode stays active. This helps on a flight that offers onboard WLAN, since the mobile radio stays blocked while local wireless features work again.

If only mobile data refuses to reconnect after you disable Airplane mode, check the mobile network settings on their own, since a stuck SIM registration can look like a leftover flight mode problem.

Restarting the phone after toggling Airplane mode clears connection states that a plain switch does not always reset, especially after the device has been offline for a while.

Frequently asked questions

WLAN sometimes needs a separate toggle. Open Settings ➔ Connections and switch WLAN back on manually if it did not reconnect automatically.
