does a HSDPA sim support 2G & 3G network for talking

I'm new to HSDPA.  Is a HSDPA sim card supports 2G and 3G network for talking via cellphone?  Is HSDPA provides high speed data transmission such as browsing webpages and email services?  Will the configuration of using HSDPA require password?  So other user can't use the HSDPA sim card on other computer or wireless devices privately?
