The invention relates to a method for charging internet services via a mobile telephone. A mobile telephone customer pays a small individual fee for various types of content (information, data base searches, travel timetables, games) when surfing on the Internet using a WAP-enabled terminal for example. Said amount can be settled via the mobile telephone network in an efficient and reliable manner. The customer data required for a payment transaction is held in a centralized manner in a data base of a payment gateway. A credit account can be authorized by a customer, whereby the provider can charge the amount to be settled thereto.
