:How long they survive totally depends on how long they give out "free" service. i.e. if they limit it to a couple of years at $250 they should be fine financially. If they make it longer than that then I think it is unlikely.
Another thing is whether they limit their "unlimited" service or not... since they advertise the device as "free unlimited for life" I would think they don't limit it which will dent their financials quite a bit.
There is a free and a premier plan. The free plan gives unlimited calling, but doesn't include all the features of the premier plan. I'm enrolled in the premier plan for $99 per year, which includes a free second line and number port.
