Starting Jan 8th you can no longer receive subsidized pricing if you are not on a plan that's currently offered i.e. shared data or promo single line plans.
You can finance, pay retail or purchase retail used devices on older plans still. You can finance or choose subsidized on the current plans. The only workaround is they are granting 1 time upgrades per account on retired plans if the customer is thought to leave for not receiving the discounted phone.
There will also be $25 activation fees when you finance a new line or upgrade.
