100% coverage* refers to geographical mobile phone coverage of Australia's landmass and coastal waters where a clear line of sight to the satellite is established when in satellite mode. It is important that you understand that the service is not guaranteed, even while in the coverage area, where there is no clear line of sight to the satellite. Obstructions such as buildings, foliage, bridges, overpasses, roofs, mountains and topography may obstruct a clear line of sight.
