The present invention relates to systems and methods for providing and billing Internet services that allow a user to select a service profile among a plurality of service profiles. The present invention assigns a service telephone number to each of the service profiles, such that each service profile is uniquely identified by its service telephone number. When the user selects and logs on to one of the service profiles, the present invention checks whether the user has subscribed for being billed on a user telephone number through a telephone network operator, and, if this is the case, the present invention allows access to the selected service profile. When access is allowed, the present invention creates a call detail record including the user telephone number as calling number and the service telephone number of the selected service profile as called number. The present invention then transmits the call detail record to a billing system of the telephone network operator.
