In the past, airplane mode was non-negotiable the moment you stepped on a flight. But as in-flight technology advances, passengers now have more options to stay connected in the sky—legally and safely. If you’re wondering whether you can use your phone’s data during a flight, the answer is yes, but with important conditions. The use of mobile data (i.e., your carrier network) is still generally special database restricted during takeoff and cruising altitude due to interference risks with aircraft communication systems.
However, airlines now offer Wi-Fi, and some support
mobile connectivity via airplane cellular networks like AeroMobile or OnAir, which operate at high altitudes with regulatory approval. Knowing when and how to use data legally can keep you connected without violating aviation laws.
Airplane Mode Isn’t Just a Suggestion—It’s a Rule. Aviation
authorities like the FAA (U.S.) and EASA (Europe) require
that all passengers enable airplane mode during flights unless otherwise instructed. This disables your device’s ability to transmit on standard mobile frequencies, preventing interference give your company a real face with aircraft systems. But here’s the nuance: you can enable Wi-Fi and Bluetooth while in airplane mode,
and this is exactly how airlines allow legal data use.
Once airplane mode is on, you can connect to the aircraft’s Wi-Fi, which may offer internet access (sometimes for a fee, sometimes free). Many major airlines now phone number list provide messaging-only plans or even full browsing and streaming packages via onboard Wi-Fi systems.
For flights equipped with in-flight cellular networks,
some airlines allow passengers to make calls, send texts, or even use mobile data through roaming. This is legal because these systems use satellite relays to avoid interfering with terrestrial cellular networks. However, usage depends on both airline policy and the mobile carrier’s roaming agreements. In most countries, inflight roaming is legal—but many airlines still restrict voice calls to maintain a peaceful cabin environment. If your carrier supports in-flight roaming and your airline permits it, you may receive a mobile signal at cruising altitude that allows limited data use. Charges, however, can be steep—so always check the cost before connecting.
