Cellular coverage is based on LTE and 3G geographic coverage. Flash uses T-Mobile as a cellular service provider. For more detailed information on coverage in your area, please see T-Mobile's coverage map.
Due to issues with certifications, regulations and wireless performance, Flash is not designed for wireless use outside of the United States.
GPS requires line of sight with satellites to receive data. The signals from satellites will pass through clouds, glass and plastic but will not go through most solid objects, such as buildings and mountains.
Please note that the bike will operate normally if outside of cellular coverage, including all electric features; the only features that will be unavailable are remote check-in and GPS location tracking via the Flash app. For more information, please see our article about connecting Flash with your phone.
