I used iPass two years ago in Eastern Europe and Asia, very good for giving access almost anywhere, even if bydial up in out of the way places. At least access is available, and it does gives access. I did find it very poorly indexed in places where there were lots of options,, say for exapml, in London.. how do you know which BT telephone box at Charring Cross staion is the one that supports Ipass and BT Broadband???
Its a nightmare. As an intellectual exercie I looked at the aussie service options THEN, and thought it lacking apart from maybe Sydney. I no longer use iPass ,as the account was gigantuous. and not clear. I find now, with wifi so prevalent, that I can survive on open hotspots and plugging into internet cafes.. BUT I woud rather not.... Its also a disgrace in Australia that airports are not free. It shows our backwardness. And very few if any, power points. The new Hobart airport which calls itself international.. has NONE at all. Typical Tasmania, lots of appearance BUT For an international visitor, I would suggest a Telstra G3 internet access card which gives a set time and unlimited access. For locals with intermittent requirements, there is little offering as the main providers steal it if it aint used within a set time.. I woud love a service provider that gave roaming access to the casual user to be charged t a main account on a pay as use basis, if they were signed up for fixed access with that provider..
Also if you are American, you may be more likely to be using a mac. Telstra have discontined iPass international for Mac
