When a user types his or her conversation on a TTY keyboard,
it is transmitted as tones through the telephone. Tones are
received by the other person's TTY, translated into text and
displayed on the screen. In order to use the TTY network, you
must have a TTY-compatible phone and be in the TTY mode to
place or receive calls. Note that most digital wireless devices
are TTY-compatible.
Data Charges and Location Based Services
Verizon Wireless charges you for all data and content sent or
received using our network (including any network overhead
and/or Internet Protocol overhead associated with content
sent or received), as well as resolution of Internet Protocol
addresses from domain names. Sending or receiving data
using a virtual private network (VPN) involves additional VPN
overhead for which you will be charged. Please note that certain
applications or widgets periodically send and receive data in
the background, without any action by the user, and you will be
billed for such data use.
Many services and applications offered through your device
may be provided by third parties. Before you use, link to or
download a service provided by a third party, or an application
such as a non–Verizon Wireless location-based GPS-type
service, chat room, marketplace or social network from
your device, you should review the terms of such service or
application and applicable privacy policy. Personal information
you submit may be read, collected or used by the service or
application provider and/or other users of those forums.
Verizon Wireless is not responsible for any information, content
or services you access, download or use from the Internet. You
