Yes, by default, activating Airplane Mode will immediately disable all wireless signals on your device, including cellular data, Bluetooth, and Wi-Fi. This is a safety protocol designed to prevent radio interference with aircraft communications. However, on most modern smartphones and tablets in 2026, you can manually re-enable Wi-Fi and Bluetooth while remaining in Airplane Mode. This is particularly useful for using in-flight Wi-Fi services or wireless headphones without accidentally activating your cellular roaming. Some newer operating systems even "remember" your choice; if you frequently turn Wi-Fi back on after enabling Airplane Mode, the device may stop turning it off automatically in the future.
