Autopay change date
The new autopay changes requiring a debit card or bank account to receive the discount goes into effect on May 18th.
EDIT: May 18th is for new and existing customers just enrolling in autopay
May 20th customers enrolled in autopay without debit card/back account/T-Mobile money will receive text messages over the next several months depending on bill cycle. They will receive a text message 30 days before their autopay discount is removed. Then a 15 day reminder, and again 3 days before. So the date for existing customers enrolled in autopay will vary from account to account.
Most reloadable cards are eligible for the autopay discount while non-reloadable are not and cannot be used for autopay.
Will update this post with more information as I get it.
