PredictWind does not sell Starlink hardware or Starlink airtime plans. These need to be purchased directly through Starlink or an authorised Starlink provider.
PredictWind works well with a Starlink internet connection, allowing you to use PredictWind features such as weather forecasts, Weather Routing and Departure Planning while connected to Starlink.
