How is there a limit???? I have never heard of that before, just on a cellphone or aircard. And even then you can pay couple of bucks more and have unlimited.
Mine is some high number...I could check, but I can't be bothered. I don't really need to worry about bandwidth it's that high.
I'm sure that they're not truly 'unmetered', but have a very generous limit. I'm positive that if someone with such a connection were to download a 1TB or even half of that, they would either get shutdown or a notice from their ISP.
Before I moved to Australia I had unlimited 8mb both ways. Now I only have fucking 25GB a month on a 8mb/128kb line.. and that really sucks!
