billb - there is no sim card in a cdma phone. There may be a memory card depending on the phone.
The sim card holds account information, ie phone number, etc. It usually can hold contact names and numbers. How many it will hold depends on the chip. On gsm, you can switch the phone you use by merely moving the sim from one phone to another. (Doesn't always work, if you have a older sim and a newer phone). With CDMA you have to have your wireless company activate the phone you want to use.
Verizon world phones have a Vodafone sim chip that is only active when used outside the US and in countries that use GSM. Their world phones will not connect to gsm networks in the US.
