T-Mobile is a global wireless carrier with a well-deserved reputation as a leader in advanced cellular data services. It offers GSM/GPRS services in more than 8,000 U.S. cities, including 45 of the top 50 markets. When using its multimode WorldClass service, T-Mobile also provides services in 100 countries around the globe. Finally, the company has the world's largest publicly accessible Wi-Fi hotspot network, with 2,200 hotspots in the United States and 200 in Europe.

T-Mobile does not have a single wireless e-mail solution. Instead, through a variety of partnerships, it supports a number of offerings on its network, including those from RIM and Synchrologic. In addition, T-Mobile supports a Web-based service, called t-zones, that provides online portal services, including e-mail. The e-mail component comes from TeamOn Systems, which was recently purchased by RIM. T-Mobile also supports Infowave's Infowave Mobile Messaging (IMM) system, which provides a secure behind-the-firewall solution for Exchange users. This system requires special client software that runs on Handspring Treo and Pocket-PC Phone Edition devices.

As noted, T-Mobile also provides Wi-Fi hotspot services, letting individuals use virtually any IP-compatible e-mail client capable of connecting back to enterprise servers. Although its coverage is limited, T-Mobile is a pioneer in this market. In addition, the company makes the point that customers can use their GPRS network for wireless mail services. Unfortunately, the integration between GPRS and Wi-Fi is limited, but you can expect that situation to improve.
