The AT&T's coverage viewer depicts a high-level approximation of wireless coverage. There are gaps in coverage that are not shown by this high-level approximation. Actual coverage may differ from map graphics and may be affected by terrain, weather, foliage, buildings and other construction, signal strength, high-usage periods, customer equipment and other factors. AT&T does not guarantee coverage and our coverage maps are not intended to show actual customer performance on the network, nor are they intended to show future network needs or build requirements inside or outside of AT&T's existing coverage areas. Coverage maps also may include areas served by unaffiliated carriers, and may depict licensed areas rather than an approximation of their coverage. Charges will be based on the location of the site receiving and transmitting the call, not the location of the subscriber. Your phone's display does not indicate the rate you will be charged.
