The risks of "$15 for $2097 worth of mobile internet"

If you must ration throughput, a much better model is one that drops its bandwidth after hitting a cap. Though nothing compares to actually upgrading your network so you don't have to grudgingly provision resources like some kind of Dickens villain.
They also have a tendency to list some of your usage on the next day when it was used before midnight. Really annoying when your using your plan up on the last day, then some of that gets transferred to the next month.
I think every person I know who has a Three phone used an amount of data in their first month whilst roaming and had a $100+ excess usage charge (often much higher).
I'm sure it's all spelled out to them upon purchasing, but it's not clear and your average user has no idea what roaming is.
This worries me greatly. (puts iPhone on WiFi mode)
A person would need an ISP account where you don't get limited on uploads (like Internode, or most non-Australian ISPs, for instance.)
A person would need to spoof the ping return address, so the ping never comes back to them. Or spoof a UDP stream where the ICMP port unreachable never comes back (or don't spoof it, and put up with 32 bytes of download for every 64k sent.)
Then, the person just starts sending and people start accruing costs.
I'm not advocating that someone should do this. I'm just worried that they might choose to.
It takes the term Denial Of Service attack to an entirely new level of bad.
It's also just going to get worse with the new "cleanfeed".
In fairness, Europe and US have large populations accessing data over many links, so the cost is spread wide. Australia accesses much US data over few links and must bear the cost of that. Data is simply more expensive in Australia.
The telco's have probably had discussions on how to make local data not part of a cap, but it would be too hard to explain to normal people how to ensure that the data is locally hosted.
I think it's actually the capacity of the mobile network. To support more throughput they'll need to install more cell towers, which is a capital expense. The telcos probably find it more profitable to restrict usage and just charge the higher users as much as possible for as long as the network will sustain it.
(I would like to do this in the US, but nobody will sell me prepaid 3G or WiMax.)
Of course, I can't even imagine how that would account for a factor of ten (the lowest on the list), much less 140.
I don't use it that often, but when I do, it works great!
