topHow many megabytes (MB) of data do I need?
A megabyte (MB) is the measurement used for the amount of information that is sent and received from the Internet when you browse the Web and download content like ringtones, wallpaper, and games. T-Mobile offers data services with different amounts of data. The 100 MB service is available if you want to access the mobile Web frequently to browse your favorite Web sites and search for music and videos. If you only want to access the mobile Web occasionally to get breaking news and stock quotes, you may want to choose the 50 MB service.
