Airplane or flight mode turns off the wireless features on your device so that you comply with airline regulations.
The Colgate® Connect app and toothbrushes use Bluetooth to communicate. This means that you can use the Colgate® Connect app in flight mode.
However, please note that your brushing history and Smile points are linked to your Colgate® Connect account and saved remotely. You must be using cellular or Wi-Fi to synchronize your data.
