Information about safeguarding
handsets
T-Mobile encourages customers to take appropriate
measures to secure their handsets and invites them to take
advantage of the features available on this handset to help
secure it from theft and/or other unauthorized access and
use. This handset has a locking function (e.g., user-defined
codes or patterns) that can serve as a first line of defense
against unauthorized use or access to stored information.
Preloaded security applications that allow customers to track
or locate misplaced devices can be found on several T-
Mobile devices. Lost or stolen devices should be immediately
reported to T-Mobile so that proper measures can be taken
to protect accounts. For additional information, visit:
www.t-mobile.com/devicesecurity and http://www.t-
