Here's how it works

Find your personal access code - it is on the second card in the CityTour Guide

Dial 030 / 340 600 301. You will be asked to enter your access code on the phone's keypad. You have now activated your CityTourbyCall service and can begin using it right away.

When prompted, simply enter the number for the commentary you wish to hear. The number for each sight is listed on its card or on the city map.

The commentary will start to play. After listening, simply hang up. To hear additional commentaries, re-dial and select another sight.
