What does HSPDA mean??

Answer 1

GSM runs on 4 bands of network, basically here in the U.S. they use 2 frequencies, which (I believe) are 850 & 1800. 900 & 1900 are international frequencies. Having all bands basically means that your phone is compatible with all GSM networks. Here in the U.S. At&t & T-mobile use GSM. GSM, is a type of wireless network.

HSDPA is strictly data, whick allows you to have broadband compatible speeds, nothing to do with voice.
