You do not all have to be on Edge. So the 2 eligible lines can be on Edge. Sometimes Verizon has promo where those under a year away form their contract ending can Edge up, but I do not believe that have that promo going on right now. So they will have to wait.
People regret signing up because they failed to study the program.
Anyway the Edge plan just changed today from 20 months to 24 months. This will actually lower your payments.
So here how Edge will work. Assuming the 2 lines in question get the cheapest version of their respective phones.
iPhone 6 is $650 so the cost will be $27.08 a month for 24 months. That line will also get a line access discount $25. So in reality that line's cost will be $2.08 higher. Really not even that since the taxes are lower because of the line discount. So it will stay about the same. In my area taxes on the discounted lines are $1.75 cheaper
The iPhone 6 Plus is $750 so that's $31.25 a month of course they get the $25 monthly discount too. So that's $6.25 a month more but probably lower due to lower taxes.
So basically those 2 lines getting those phones will raise the cost of your bill maybe $5 a month.
The benefit of Edge is the only upfront cost is the sales tax on those 2 phones which will probably be between $60-$150 depending on what the sales tax rate is in your area. On a subsidy the iPhone 6 would be $200 plus $30 upgrade fee plus sales tax the 6 plus would be $300 plus $30 upgrade fee plus tax. So on subsidy you're looking at $560 plus sales tax upfront.
The person not doing anything plan pricing won't change.
As long as you are not upgrading early and you make all your Edge payments the phone is yours to keep or do whatever. You only turn it in if you haven't made all 24 payments and you want to upgrade before 24 months. In order to upgrade early you'd have to pay at least 75% the cost of the phone or wait 18 months. Which is the same thing.
After you pay the Edge plan off and if you are not upgrading again you lose the Edge discount, but Verizon has a Month2Month discount for lines off contract which is the same thing. You'll just have to log in an add that manually or call in to activate it.
