T-Mobile USA has added street-level coverage maps of its wireless network. Using an 11-point rating system, users can enter an address or intersection to check maps and predict wireless coverage area outdoors.

Meant as a guide, the maps do not guarantee service availability, even within a coverage area. And there are several factors, including network changes, traffic volume, service outages, technical limitations, signal strength, equipment, terrain, structures, weather and other conditions that may interfere with actual service, quality and availability.

Portions of the mapped areas include networks that are operated by T-Mobile partners and affiliates. If consumers travel outside of these coverage areas, their phone will not work.
