These maps are not a guarantee of coverage and contain areas of no service, and are a general prediction of where rates apply based on our internal data. Wireless service is subject to network and transmission limitations, including cell site unavailability, particularly near boundaries and in remote areas. Customer equipment, weather, topography, and other environmental considerations associated with radio technology also affect service, and service may vary significantly within buildings. Some information on service outside the proprietary network, and we cannot vouch for its accuracy.
