This paper describes a context aware mobile service based on Short Message Service, SMS, and Multimedia Message Service, MMS, for use in tourism. The goal of this research was to determine the contextual information which defines the tourists while they go sightseeing in some area and to use that information, to present them some useful information about the places they are visiting. As a result from this research a prototype system was build and the defined use cases were tested. The built system is a good base for developing various services on top of it which will use the collected contextual information.
