This study examines how methods proposed to price traffic in the fixed Internet can be accepted by customers of 3G mobile services. Most previously proposed congestion pricing models are complicated and therefore difficult to be accepted by customers. Simple data pricing methods are needed in today’s 3G networks. A congestion pricing method is proposed only for customers willing to pay more during congestion. Other simple methods include usage pricing with cost constrains, event and content based pricing. Event and content based pricing have been successfully used in 2G and 2.5G (GPRS) mobile networks. They will also play an important role in pricing decisions in 3G, since the customer is interesetd for his delivered services and not for the number of bytes.
