Poor performance is almost always related to high usage as you would imagine in NY City. Show me a system with few users and I'll show you a system where you almost always have good call quality. That provider will either be more expensive or about to be bought by someone else.
Normally the only way the small providers make money is through roaming agreements.
The big 2 are going all out with data now. Even the voice calls will be treated as purely as packet data calls. Voice calls won't even be hitting a traditional "switch" but will be going through routers as packet data. All this is very expensive to the service providers of course. But data and data apps is where the growth and profit is now.
