GPRS connections are limited to 48kbps of speed while EDGE is limited to a max of 384kbps. YOu need to subscribe to this service , which ever one is available. Your carrier might also charge you for using the same.. So for further details contact to your cc of your carrier

A standard wireless network card will not work in this case, as that requires a hotspot to connect to. What you'll need is a cellular connection card(check with your local cell phone providers to see what they offer)
