More specifically, a method and system for controlled access to content services (2) where a terminal user (1) can be allowed (b2) or refused (b1) access to a content service (2) and the use thereof are disclosed. The invention provides a solution to enable controlled online access from a terminal user (1) to a content service (2) wherein no time-consuming registration steps, which are also annoying to the customer, or time-consuming billing steps have to be performed, only one terminal (5) is needed by the user (1) and only one connection needs to be active at the time. The invention is particularly useful for mobile terminal users, like i-mode site customers, to get comfortable access to chargeable Internet services using a payment gateway accessible through the packet-switched GPRS network and a voice response system accessible through the circuit-switched GSM network.
