You can generally only text during takeoff if you are using Internet-based messaging via the aircraft's Wi-Fi, and only after the crew confirms the system is active. In 2026, most airlines require your phone to be in Airplane Mode once the cabin doors close to prevent cellular signals from interfering with sensitive cockpit instruments. Traditional SMS (cellular) texting is blocked because your phone cannot maintain a ground-tower connection at high speeds and altitudes. However, many 2026 carriers now offer "Free Messaging" plans for apps like WhatsApp, iMessage, and Telegram. While some new systems activate as soon as you push back, most still wait until the plane reaches 10,000 feet (3,000 meters), meaning there is a brief "silent window" during the actual climb where all digital communication is typically paused.
