HSDPA, 3G and GPRS all support data services and are all
chargeable, but if u're going to use a lot then u will sign up a
data VAS plan. like for this, i get to use data unlimited (up to
10GB actually) paying a flat rate. if u dun sign up for the plan u
will be charged based on volume of data.
using phone to access [email protected] can be a painful process
sometimes u noe. but it's very suited for massive and quick
downloads on ur computer or laptop.
