As i told, my research in real life (in many countries, when i was working in satellite internet area), shows, the second you announce "unlimited" tariffs recommended limits - customer will suck 'em all. Even he dont want this traffic, most of people think if they pay, they must suck till last drop.
So choice(just example) - you know for sure your limit 1-2gb and your account will stop when it finished, and you know there is a limit, but it is 10gb(and u dont know that) and account just will be with lower speed. Thats it. What is prefferable?
About lebanon... there situation much better. In Cyprus i had collegaues, they like Kazaa a lot... they got DSL from Cyta. Cyta disconnect him sudden after 1 month, and no excuse at all. They just tell "we have no technical availability of service for you". Later over some friends they got info, that it was because they download too much. If country is too civil, ISP will lie for you, if you are uncomfortable customer, but they are scared because of laws.
In Germany, if i'm ISP, first of all you are stuck with me by contract for years, and it is auto-renewable, you just dont have choice to leave me. If in contract not mentioned you need to have all ports opened, i can leave for you IM, web,shaped myspace and etc, and try to download... and you can do nothing. The second you go to court, you fall in the battle for few years, and expirience shows you have choices:
1)Pay hundreds of thousands if you lose the battle, and because you don't have them - go to jail. Because chances to play with professional ISP lawyers and ur lawyer is different, noone taking risk anymore.
2)Pay "disconnection" free, usually few thousands of bucks.
3)Try to find hole in contract, that i will disconnect you. Usually also if ISP very big, they have Fair Usage, if you download more XXX Gb in 3 month - he disconnect you, and pay you "damage" fee, smth about 300-400 bucks.
About latency - not a big issue at all. Yes, we have lost maybe 5-10% of market cause of customers who need decent latency, but with current "fiber" prices and how much they want to pay, it is just "cosmetic" part of customers. There is almost no profit on them with current government prices. First of all because there is no normal "underground" infrastructure to deliver stable latency for customers, air is too "busy" with interference, so even fiber will have 280ms, it will be useless, cause let's say we see on IDM network jitter +-300-400ms, just on local loops. Our network is better, but still because of many hops it will be +-50ms, for broadband customers.
You will say, why on Wigo latency is nice? Because still they didnt reach profit level. Base Station cost more than $100000(for 3G i didnt research how much exactly), customers amount must be near maximum to follow business plan. And as far as i know, latency will be different, when BSS is full.
