I bought vodafone about two weeks ago and instantly regretted it. I needed a mobile network with lots of internet as well as free international calls. As a student I got a mouth watering offer from Vodafone. I immediately took it and that too a 12 month contract plan. But alas! There is no network at my home. Although, at the store they showed me that I would be getting good network, but I am getting far from worse. My suggestion - Go for Telstra or anyone using their network but a big NO NO for vodafone.
