haha.. i tot of that too.. but unfortunately, u cant do that...
But..u can subscribe to data package using ur phone account for IINM RM99 or RM120 (not sure) permonth unlimited usage.. then u need to have a usb cable to connect ur phone to ur pc/lappy and dial up as usual.. its quite reliable if u intend to use it for a short while becos u can always call back the maxis center to unsubscribe at any time (after >1month iinm)..

i've used this service once but a very2 long time ago.. try dialling 123 and ask them..

3g phone is used to connect to the service.. if u dunwan to subscribe to RM99 per month oso can, but u have to pay RM0.01 per kb of donwload.. and i tell u, nowadays, most website are more than 1MB to download.. so that's like 1000kb x 0.01 = RM10 ady.. that is if u only wanna visit just one site..

so might as well get the RM99 unlimited data package..
