The more important question is whether they will unlock phones (in our case, iPhone 6 with 10 months of contract remaining) so you could switch to another provider and not have to buy new phones too. Although I guess as long as the contract is ended, the AT&T phones could still be sold off even if still locked to that network.
A related question... why wouldn't we qualify for the $15/month instead of $40/month "device" charge on one of their current plans, if we're still in contract, and they're prompting us to change (obviously we don't have to, but that's what they want, right?) I'd be quite happy with a shared 15GB plus two "bring your own" devices for $130 which is less than I'm paying now, but not if it's $180.
