As of 2026, you generally cannot make traditional cellular voice calls on a plane due to long-standing FAA and FCC regulations that prohibit the use of cellular networks during flight to prevent interference with ground-based towers and aircraft systems. However, you can make calls using Wi-Fi if the airline permits it. Many modern carriers now offer high-speed satellite Wi-Fi (like Starlink or Viasat) that supports VoIP (Voice over IP) services such as WhatsApp, FaceTime Audio, or Skype. While the technology allows it, many airlines still discourage or explicitly ban voice and video calls in their "passenger conduct" policies to maintain a quiet cabin environment and avoid annoying fellow travelers. If you must make a call, it is best to check the specific airline's Wi-Fi portal rules once onboard. Usually, text-based messaging is encouraged, while audible conversations are restricted. Always use headphones if you are watching a video or listening to a message to ensure you don't disturb those around you in the tight quarters of the cabin.
