In the daily life of a mobile user (meaning a user of mobile communication/data equipment), there are many cases which involve possible misuse and over-charging of his account, regardless whether it is a pre-paid or a post-paid account. Related problems can appear in many forms. Two forms should be mentioned exemplarily. One form is the misuse in the case of loss or theft of mobile phones. For example, the mobile phone of a user is stolen. Before the user realizes it and is able to pick up his legitimacy information (e.g. PIN Personal Identification Number / PUK Pin Unlocking Key which are possibly stored at home) and to inform his operator to block further use of the SIM (Subscriber Identity Module) card or the mobile phone, the thief could have already made a lot of expensive calls. This misuse case usually uses up the whole rest money of a pre-paid account or results in an expensive bill for a post-paid account. Another form is to prevent an account from intended or unintended over-charging. An example is the control of mobile phone budgets of kids by their parents. Until now it is merely possible to take precautionary measures in some cases by forms of limited credit balance.
