I'm paying 125 for 5 lines (unlimited) with fantastic coverage and excellent speeds. Switched to Cricket Wireless (owned by ATT) about 2 years ago. This is with taxes and fees included. Can't beat it at this point!!
The Verizon Go Unlimited plan sucks, plain and simple. You can get "de-prioritized" at any time Verizon determines the network you are connecting to is busy. 1/2 the time I try to use my phone around town, I can't connect, open the App store, etc.
All this is really does is force you to "upgrade" to the next higher plan for $10 more a line.
I currently pay $175 for 4 lines, service only. Seriously looking at some of the Pre-paid plans as we are treated like pre-paid as it is.
