High-Speed Data Connectivity via T-Mobile's 3G/4G Network
T-Mobile's UMTS/HSDPA/HSPA+ 3G/4G network, which operates on the 1700/2100 MHz AWS spectrum, and it can achieve theoretical download speeds of up to 21 Mbps. It's designed to automatically connect to the best available network (4G, 3G, or GSM/GPRS/EDGE) to provide faster data speeds when accessing the Web.

In areas where the 3G/4G network is not available, you'll continue to receive service on the via T-Mobile's EDGE network (which stands for "Enhanced Data Rates for Global Evolution"). This high-speed, mobile data and Internet access technology is fast enough to support a wide range of advanced data services (with average data speeds between 75-135Kbps), including full picture and video messaging, high-speed color Internet access, and e-mail on the go.

With typical download speeds that are on par with or faster than competing 4G technologies, T-Mobile's HSPA+ network provides fast data speeds--up to 3 times faster than AT&T and Verizon's standard 3G networks--while allowing simultaneous voice and data capabilities for the ultimate wireless voice and data experience. You'll enjoy faster Web browsing, uninterrupted video streaming, and quicker app downloads.
