Original press release
Ericsson Unveils the Smallest World Phone - in the World - the T28 World GSM phone
Cambridge Telcom Report, Sept 27, 1999
Wednesday at the PCS Trade Show in New Orleans, USA, Ericsson unveiled
the second in a series of its World Phones to be available after the New
Year. The T28 WORLD is designed to operate on the GSM 900 and GSM 1900
bands and offers you the opportunity to use the phone in Europe,
Asia/Pacific and the Americas.
Measuring a mere 97x50x15mm (2.5x 1.3x .4 inches) and weighing just 83
grams (less than 3 ounces) the T28 WORLD features a full graphic display
for easy readability and features an active flip with a clever release
button on the side of the phone. The voice dialing feature lets you
contact someone simply by saying their name, calls can also be answered
or rejected by using voice only. The T28 WORLD also features the popular
vibrating alert, which makes sure you don't miss calls in noisy
environments and don't disturb others with your ring signal in more
Automatic time zone update is an especially useful feature when
traveling globally (network dependent). The T28 automatically updates
the time when the user moves from one time zone to another and functions
as a world clock, alarm, calculator and stopwatch. Additionally, the
T28 WORLD comes with a Global Travel Charger that allows you to charge
your phone wherever you are in the world.
"Ericsson's T28 series of phones are now truly global. We have launched
the T28s for GSM 900/1800 networks, the ER 207 which is based on the T28
design and technology platform for the Japanese PDC network and now the
T28 WORLD which covers five continents, over 120 countries," says Jan
Ahrenbring, Vice President Marketing and Communications at Ericsson
The T28 WORLD contains remarkable new technology supporting the
complete range of GSM phase 2 - and where applicable GSM phase 2+
functions. Based on a new 3-volt platform the phone's components are
smaller and thereby effect less power consumption ensuring an overall
improvement in performance. Advanced software has been developed and
utilized to ensure the user interface is faster, more accurate and
easier to navigate. Examples of some new features resulting from this
software are the status list and profiles. The status list allows you to
view available, or indeed, occupied, memory positions, stored positions
and stored message types. Profiles lets you establish different
profiles on your T28 WORLD e.g. you can choose different ring signals,
including the vibrating alert and different ring volumes for different
Ericsson T28 WORLD is an exquisite example of cutting-edge technology
and sensuously sculpted design. Its lines and contours have been
delicately arched to give it the clear, simple, form traditionally
associated with Scandinavian design. Finished in Urban Grey and
Metropolitan Blue these colours capture the stylish image of the phone.
Other T28 WORLD features include:
-- Phone Book with 99 names
-- The popular games Tetris and Solitaire
-- Conference calls
-- Call hold/Call wait
-- Alternate Line Service
-- Advice of charge charging
-- Fixed dialing numbers
-- Call barring
-- Calling Line Identification
Another aspect is that the T28 WORLD contains a power gauging function.
This information is presented in minutes for both talk time and standby
time and thereby ensures you remain aware of how much power is available
to you. With the battery provided, minimum talk time is 1 hour and 33
minutes, maximum talk time 3 hours and 35 minutes. Minimum standby time
is 32 hours, maximum 50 hours. With additional batteries, maximum talk
time is 10 hours and 27 minutes and maximum standby time is 150 hours.
Ericsson has developed an all-new series of accessories to compliment
the T28 WORLD. These accessories can best be described as "intelligent
accessories" in that they provide more than the usually functions. The
Desktop Charger, for instance, offers you detailed information about the
amount of charging time left before your battery is fully charged.
