MAP INFORMATION: Maps predict and approximate our anticipated wireless coverage area outdoors, which varies from location to location. Maps may include locations with limited or no coverage, and do not guarantee service availability. Even within coverage areas, factors — including network changes, traffic volume, service outages, technical limitations, signal strength, your equipment, terrain, structures, foliage, weather and other conditions — may interfere with service quality and availability, including the ability to make, receive and maintain calls and to send and receive data & messages. Portions of the mapped areas include networks operated by our roaming partners, and we are not responsible for the performance of those networks. 3G Coverage requires a 3G-capable device. Devices that are not purchased from T-Mobile or an authorized dealer may not work on our network. T-Mobile to T-Mobile calls are directly dialed between T-Mobile customer devices while on the T-Mobile USA network (and not roaming on any domestic or international network); calls to voicemail and other T-Mobile service numbers not included. Roaming: Nationwide roaming refers to usage while on a roaming partner's network within the domestic coverage area. Nationwide roaming is currently not available for webConnect™ data plans. International roaming incurs additional charges and refers to usage while you are outside of the United States. 850 Roaming Coverage requires a multi-band (850/1900 MHz) GSM/GPRS device. Certain devices and features (e.g., picture and video messaging) will not work if you are roaming. Ask a sales representative or visit www.t-mobile.com/morecoverage for more information regarding device requirements and 3G and 850 MHz coverage. If you travel outside of coverage areas, your device will not work.
