BT Onephone
Making life simpler
In today’s busy world we expect to
be in contact wherever we are.
Technological advances have made
this possible, but sometimes at the
expense of simplicity. Increasingly
we have a baf fling array of products
and services from which to choose,
and for those trying to contact you,
finding your location can be time
consuming and frustrating.
At BT we believe that keeping in
contact should be easy and
uncomplicated. BT Onephone places
the emphasis on fewer products and
a seamless ser vice.
Developed in association with
Ericsson, BT Onephone is a world
first. It’s the only cordless phone
you can use from your home
telephone line and the cellular
network. And because it’s digital
you can be sure of call quality and
clarity, all within one phone.
Some of the benefits that the BT
Onephone will bring you are:
Flexibility – you can use the same
phone at home or away.
Enhanced features – when using
BT Onephone in the home you can
Introduction
use all the extra benefits a mobile
phone brings such as directory of
names, tailored ring tones and
increased security.
Simplifying life – Your BT
Onephone can go wher ever you go.
Upstairs, downstairs, out in the
garden – your BT Onephone is
per fectly at home anywhere and it
lets you stay in touch. You can even
take it on holiday. All of this with
just one handset. That’s why life’s
so much simpler with BT Onephone.
BT Flexinumber
BT Onephone can be used with a
single number ser vice – such as BT
Flexinumber – which means no need
for multiple handsets, complicated
call-diver ts or a string of numbers.
You decide when and wher e you
take your calls wherever you
happen to be (for more information
please see page 22).
If you are experiencing
problems either setting up
or using your BT Onephone,
please phone our Helpline
on 0345 860 860.

Please note: If you go out of range
of a base station for a long time while
your handset is switched ON, it may
take more than 20 minutes to ‘find’ the
base station again when you come
back within range. However, by simply
switching the handset OFF for a
moment, then ON again, it will find
the base station within a few seconds.
