• Never leave your wireless device unattended,

• Review your bill and report any suspicious calling
activity. If we conclude that the calls are fraudulent,
you will not be held responsible for the charges.
• Record your wireless device’s electronic serial
number in the back of this guide and keep it safe.
• Have your wireless device serviced only at a Verizon
Wireless Communications Store or by an authorized
agent, retailer, manufacturer’s service center or other
repair center.
Assistive Communication Devices
TTY (Text Telephony) and TDD (Telecommunications
Device for the Deaf) allow individuals who are deaf, hard
of hearing, or have speech or language disabilities to
communicate by telephone.
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.
