Why don't CDMA systems have SIM cards in the handset?

Why don't CDMA systems have SIM cards in the handset?

 

The GSM air interface standard, which uses SIM cards, was designed so that your phone number and other information that identifies you as you -- could be easily transferred from one phone to another by simply transferring the card. The CDMA standard was not designed so that your identity would be that mobile. CDMA "hardwires" your identity into the components of the phone so that, among many other reasons, wireless operators hold more control over their customers and the mobile phones they use.
