Unlimited?
Well, even those of you claiming unlimited should mean just that, are actually limited by the rate of your modem.
The reality is the radio spectrum bandwidth is a scarce resource and you cannot get as much down it than a fibre optic cable. It is simply not possible to carry the whole internet over a few MHz of cellular band in competition with the voice traffic already there. It is sheer folly to believe so.
Radio spectrum should simply not be used, sold or marketed as a means of bypassing fixed lines (or WiFi connected to fixed lines) for stationary internet connections. The wireless operators that pretend/think they are operating a fibre optic ADSL service lying imbiciles and are the mobile industry's own worst enemy.
'Unlimited' means to me that I'm not going to get a nasty bill-shock at the end of the month. If I get throttled - fair enough.
Disclosure: I just came back from a business trip where I spent the time trying to convince the operator that they have to prioritize iPhones (etc) over broadband modems - the modems are consuming somewhere betwenn 10 and 50 times more resources (databytes base station power, backhaul etc) than the 1GByte a monthe average iPhone user.
Do you think it is really fair that you consume 50 times more data but only pay the same and get the same quality of service? If you do, then say goodbye to breakfast buffets and all you can eat data plans.
