I looked at these prices and about fell off my chair at first... had the same "$40 per smartphone? WTH?" reaction... Then I actually did some number crunching. I can't compare it to current Verizon prices as I'm not a Verizon customer, but comparing to AT&T, the prices actually come pretty dang close to my current setup with minimal tradeoff.
Taking away my 50% discount on my core package and primary data plan, I have the following (before fees and taxes):
2100 min Familytalk w/Rollover -$100
Unlimited Family Text - $30
My "Unlimited" LTE data -$30
Wife's phone add-on to FT plan -$10
Wife's 2gb Iphone data - $25.00
Friend's phone add-on to FT plan -$10
Son's phone add-on to FT plan -$10
Total before fees = $215
With the Verizon plan, I'd have:
My smartphone - $40
Wife's smartphone - $40
Friend's basic phone - $30
Son's basic phone - $30 (would probably upgrade his to smartphone)
6gb Shared data -$80 (based on mine and wife's current monthly average, me = 3-4gb/m, her = 1-1.5gb/m)
Verizon price = $210 ($220 if I upgraded son to smartphone)
With the Verizon plan, I'd lose my own unlimited data but gain unlimited voice minutes and data for the 2 phones on my account that don't have it. I hate to say it, but that's actually a pretty fair deal assuming, of course, that you think the carrier prices are a fair deal in the first place.
Did I miss anything in my calculations?
