All cellular phones need a battery to operate. Most
cell phone handset units will accept a "standard"
or "extended" battery, with additional output of
the extended adding to the length of time the battery
will power the handset.

a cover for the protection of the cell phone, and
some of these covers provide intended protection
from Radio Frequency or RF type radiation.

over short distances between telephones, computers
and other devices possible without the use of wires.

most cost-effective rates for different types and
amounts of usage by the cellular subscriber.

CELL
The basic geographic unit of a cellular system and
the basis for the generic industry term "cellular."
A city or county is divided into small "cells,"
each of which is equipped with a low-powered radio
transmitter/receiver. The cells can vary in size
depending on terrain and capacity demands. By controlling
the transmission power and the radio frequencies
assigned from one cell to another, a computer at
the Mobile Telephone Switching Office (MTSO) monitors
the movement and transfers (or hands off) the phone
call to another cell and another radio frequency
as needed.
CHARGERS
Please use the correct charger for your cell phone
battery. All cell phones we give or sell come with
a free desktop charger, unless otherwise stated.
Chargers are often referred to as "overnight" or
"rapid", with overnight chargers fully charging
in eight to ten hours from beginning of cycle. They
fill at a low charge rate, and sometimes lack the
safety features of preventing overcharge because
batteries can better withstand low charging current.
Rapid chargers recharge the battery or batteries
more quickly. The charge isn't continuous; rather,
it's reduced as the battery reaches full charge.
Sub types of battery chargers include vehicle cigarette
lighter plug-ins, desktop chargers intended for
indoor use on a flat surface, and small travel chargers
that simply plug into an electrical outlet. There
are also solar type cell phone battery chargers on
the market.
