Management system for SIM cards

摘要

The invention is based on the idea that in some part of a data communication network there is a centralized data-base/information storage, wherein all SIM information is stored. The centralized database allows a more flexible management of SIMs, whereby invoicing, updating and other functions can be made very flexible and convenient. For management of the centralized database and as an interface to other systems there is a specific server. <IMAGE>
