hey, my dad has a vodafone 3g usb internet dongle, it has a cap of 3gb, how long can i play wow on it for, i will mostly be using it when i am in the car
If you do not use voice chat, about 20-30 hours. If you do, about 10-15 hours. You will also find WoW is unplayable in a car due to lag and dropouts.
By the way, your signature picture is huge. You should cut it down to regulation size (500x150 max, 50KB)
