Verizon Wireless iPhone 13 Pro on us with trade-in of current phone on Unlimited Plan

Yes that's correct it's 24 or 30 months now.

When is it 24 and when 30?

you choose when you're choosing colors and GB

This deal will get a lot of thumbs down as it's bill credits but if you are interested in upgrading anyway and plan on sticking with Verizon it's a good deal. Plus they are not (yet) pulling that 36 month crap like AT&T.

Thinking about doing this deal, but a have a small barely noticeable crack on my screen. Will they cut my credit in half? I couldn't find anywhere how they account for the condition of the traded phone.

Just seems this is as good as it is going to get for my situation. They make it not for everyone of coarse.
Some people are still in contract for previous phones if they want to keep getting the discount.
I have a family of 3 phones just did this upgrade iPhone XR trade in's I called a rep to do the transaction and get the breakdown

$800 per line credit for trade in so iPhone 13 is 0$ a month. (I hope he applied it over the 24 month finance and not the 30 month, it is $0 either way but they bill it with a full monthly price and then credit that back in promotion on the same bill for instance it would show on $33.33 added onto the bill then a credit of $33.33 to zero it out and then after that month the phone buyout if I was to leave is $799-$33.33= $765.67 and after the following month it would be another $33.33 less and so on for 2 years)

Free doesn't mean it won't cost you no money, upfront fees for 3 lines
~ 35 dollar activation per line ($105)
Tax on each iPhone 13 retail price ($150)
$255.00 upfront to get it ordered

Plan changes,
Need eligible unlimited 5G plan to get promotion…. we had a starter 4g plan for $45 a line with 3 lines, had to upgraded plan, 5G eligible plans start at $55 a line with 3 lines. So now our monthly plan is $30 more a month ($720 increase from our previous bill over 2 years) not mention there were $13 in plan one time plan change fees
May take 2 billing cycles for the promotion to kick in as verizon needs to receive your old phone and inspect it until then you will pay uncredited full retail finance price on each bill, once your return phone checks out ok you will receive back credit for the full retail monthly price adjusted to what your promotion cost would be. I'm my case I will pay $33.33 then receive the additional credit on the second or third bill to square up.

Bills are going to be very confusing for the first couple months as they never itemize in layman's terms. It's always prorated and credited with fees fees fees.

3 phones over 2 years is about $1000 extra in monthly plan and upfront fees… not even factoring in 3 phone cases or damage/loss insurance.

Good deal for me? I guess so.
Free Phone? Kind of
Is this world going to hell in a hand basket? Yup
