<p>The invention concerns a SIM card for a mobile communication device, said SIM card being enabled to use SIM application toolkit for cooperation with said mobile communication device for establishing and/or maintaining access from and to at least one internet communication service (ICS). Preferably, said SIM card comprises a client, which when run is establishing and maintaining access from and to at least one internet communication service (ICS), which is available to a user on a PC, wherein a memory of said SIM card stores a first data record comprising user specific ICS data, such as login name and/or password; and is enabled for storing a second data record comprising callee specific ICS data, such as callee ID and/or presence information, and wherein said client when run is enabling said mobile communication device to transmit at least part of said first data record to a central gateway, which is in connection both to a network for the mobile communication device and said internet communication service, for establishing and/or maintaining a connection to said central gateway; and during a call request, provide said central gateway with at least part of said second data record for providing a connection to at least one selected callee. Accordingly, mobile capabilities of accessing, maintaining and updating ICS services using e.g. a standard mobile phone has been provided by said SIM card, system and method according to the invention. With the invention, ICS services will be accessible to the user immediately after inserting the SIM card in virtually any communication device existing today. Accordingly, presently available mobile communication devices, even standard mobile telephones, can be provided ICS, which the owner or user of the mobile communication device already have established on any, e.g. stationary or laptop PC. One advantage of the invention is that it is not limited to such WiFi enabled devices, but works on existing 2G and 3G devices. This provides the added advantage of calls being established from any one mobile communication device comprising such a SIM card according to the invention using a IPC service, such as Skype for voice calls or sending text messages, may significantly reduce his or her telephone bill costs, especially if the person to which the device user is calling, lives abroad, eliminating high transfer costs between phone companies.</p> |
