A:Answer Hi, Jenn. Fitbit devices do not only work with Wi-Fi; they primarily use Bluetooth to sync data with your phone, which then connects to the internet via Wi-Fi or cellular data to upload the information to the Fitbit servers, so you can use a Fitbit even if you don't have a direct Wi-Fi connection, as long as your phone has internet access.
