The annual data plan (available for 60, 15 and 5 minute update intervals) should be purchased in addition to the Connect unit and allows automatic uploads of weather data from remote field sites to the Davis website at weatherlink.com using a data link via the standard 3G/GPRS mobile/cellular phone network.
Your data plan will need to be renewed on a yearly basis.
