In some cases, your phone may be on, but the attendant will advise all passengers to use the aeroplane’s WiFi for their internet activities. Most modern planes sometimes allow passengers to use their phones as best as they can without turning them off or putting them on flight mode.
Reasons Why Phones Are Turned Off or Put On Flight Mode During Flight
