SIM Service Programming


Hi all,
I have an UK SIM card, which uses callback to make outgoing calls. When I dial a number the phone says "Changed by SIM" and disconnects the call, then returns the call. It seems the SIM card is programmed to replace the dialed number with something or add a prefix. Does someone knows how do they do that? Is it possible for me to program another SIM card to do the same?
