Please note that while we have mapped our network coverage as accurately as possible based on our latest available data and tools, our coverage maps only provide a general indication of the coverage service areas. As with all mobile phone networks, there may be some areas where reception is limited or unavailable. There are also factors beyond our control that may cause coverage to vary within an area, e.g. general network traffic, distance from the mobile tower, handset type and quality, high or large buildings, basements, lifts, underground car parks, tunnels and geographical features. This may mean reception is unavailable, degraded or subject to interruption. Our map is not an indication of our in-building coverage.
