Abstract: Billing method for billing a call by a subscriber identified with a SIM card (10) in a telecommunications system (2) to said subscriber, comprising: Determination of the duration of the call by means of a time-measuring device (100) integrated into the SIM card (10); Evaluation of the amount to be billed based upon the determined call duration and at least one tariff table stored in the SIM card (10). The tariff tables are stored in a tariff server (6), and can be remotely loaded into the SIM card (10) through said telecommunications network (2).
