I was in pak recently (Sept/Oct) and used my nokia N80 as a modem to connect to the internet...and it was painful :-S I had 2 GPRS enabled SIMs - one from Warid, and one from UFone...Warid GPRS enabled on Pre-Paid, while UFone was enabled on Post-Paid...
Warid was better in terms of speed, connecting at 454kbps most times, occasionally connecting at 115kbps depending on my location...HOWEVER, the connection was horrible! it would ALWAYS disconnect within the first minute if i was doing anything that required a constant/secure connection, e.g. checking my email (hotmail), while it was loading the page...after reconnecting, it would allow me to work away for 8 - 10 mins, before disconnecting again...and the rate was outrageous too...i was going through scratch cards for refills like there's no tomorrow...
Someone recommended UFone after hearing about the problems i was having with Warid...and yes, the connection was more stable for UFone, not disconnecting often, but the speed was just horrible! it would never connect faster than 115Kbps, and even then, the pages would take forever to load...something as simple as checking my email, would require 10 mins to login and load the main page where i could view the emails...their rates were OK though...perhaps cuz it was on Post-Paid...
towards the end of my trip, I heard that telenors GPRS is the best in terms of speed and reliability/stability...but it was only available on Post-Paid as well...and i didn't want to get a 3rd SIM while i was there

so i just stuck it out with Warid and UFone...perhaps on my next trip to pak, i'll try telenor too...
hope this helps
