What is stored in a cellphone's SIM card? All Contacts (ph numbers and names), settings, etc.? Or is there individual cellphone data stored on Vodafone / Telecom computers? And are SIM cards used only by Vodaphone, id so, what do Telecom cellphones have?

Finally, are SIM cards similar to the chips found on credit cards or other 'smart cards'?

Depending on your phone, you can store about 16 or 32kB of contacts or messages on your sim card - most phones these days (ie. newer than alcatel 311's) that can hold more than 20 txts will hold their messages on the phone itself. The contacts are stored on the SIM card - you'd be stuffed trying to put a contact in on no signal otherwise.

As far as the chip goes - I suppose they would be in some ways similar to those in phonecards etc... but of course totally different chips. I don't think a pay phone would be too happy about charging to a sim card :).
