Abstract: An arrangement for providing a wireless data service from a service provider (SP) to a wireless terminal (WT). The arrangement comprises a public telephone (PT). In order to provide packet-switched connection, which can be shared among multiple terminals, the arrangement comprises a filter (F) that directs voice traffic to a circuit-switched data path (114) between an exchange (EX) and the filter, and data services to a packet-switched data path (116) between the a network (DN) and the filter. Voice traffic and data services share a common data path (112) between the public telephone (PT) and the filter. There are wireless communication means, such as a WLAN base station (WB) and an ADSL terminal (AT), operationally coupled to the filter, for conveying the wireless data service to the wireless terminal (WT). Debiting means (R, DB) control debiting of the wireless terminal for the use of the wireless data service.
