In Hong Kong, dial-up is pretty much unlimited (as is broadband - we 
don't stupid lobbies over here) but you pay less if you don't use as 
much time as the maximum price cap (you are charged up to 12USD and any 
time over that is free)

GPRS is not that faster than dial-up and in fact, it is frequently 
SLOWER than dial-up. With GPRS, you get the leftover bandwidth and so if 
the area you are in is busy...it will be way slower than dial-up. With 
dial-up and a 'clean' line, you get 56kbits but with GPRS, you rarely 
get that 64kbits theoretical maximum. 9kbits or 14.4kbits is the norm. I 
was a user of a unlimited GPRS data service so I know.

These must be what the 7mbit connections use.
