Telestet 'Smart Tourist Guide' Has Information 'On the Spot'

July 29, 1999

ATHENS, Greece -- Wish you could leave the
guidebook behind while you travel and still learn about the Acropolis®
Starting today, your wish is granted.

'Smart Tourist Guide' is the latest innovation available to Telestet's nearly
one million Greek customers and the thousands of vacationers who flock
to Greece and use their mobile phones on the company's intelligent digital
network.

Telestet's network locates callers who dial "1230" within 500
meters of any one of 18 popular Greek sites and provides a vivid
description in any one of four languages; English, German, Italian, or
Greek. Smart Tourist Guide locations include the Acropolis, the National
Archeological Museum, Ancient Olympia, Delphi and sites on several
Greek islands.

Telestet is the only Greek mobile telephone provider with the service.

The messages, which can be up to four minutes long, are billed at the
national rate based on tariff plans for Telestet customers or at the normal
roaming rates for visiting callers.

"We are pleased to help everyone learn more about Greek art,
history and culture through this innovative use of our Telestet
network," said Dimitris Lolis, Executive Director of Marketing and
Sales for Stet Hellas, owner of the Telestet brand.

Stet Hellas will promote the service in brochures on display throughout the
country at major airports, harbors, hotels, tourist information booths and
official Telestet dealer locations.

Travellers without mobile service on the European GSM standard can
access Smart Tourist Guide by signing up for Telestet's pre-paid mobile
service, B Free. Visitors can become Telestet customers by purchasing a
handset and B Free start-up service at any one of hundreds of Telestet
dealers, including the Telestet Exclusive kiosk at Athens International
Airport. Because service is paid for in advance, there's no contract, no
monthly bill, no hidden charges, and no waiting for service. For more
