I work on cadi all the time without sim cards. Even without the sim card there are things you have to definitely have cadi to accomplish such as a "Zero Position Test". If the sim card is missing you will never be able to do this without cadi. Common sense should tell you which is the better choice, some knock of European modu tool or the real deal OEM schindler tool(and it's half the price)
