My wife's iphone 5 died, and we can either get her a new one with Cspire and tack on $40 a month or so to our bill. We have 3 phones with them now with 2 of them on Unlimited everything plans from a few years ago. Or we can give up the two unlimited plans and go with Verizon's XXL shared plan (24gigs/month) and they have offered us 3 coupons of some sort for $200 off each iPhone 6s Plus 64g's. Is it worth giving up the unlimited plans for this deal? This would be our first foray into shared data and we're concerned about using too much, even though we haven't used over 20 gigs a month all together before.
