Remember, you'll need to trade in an eligible device in "good condition" to get these deals. Eligible devices vary, but range from the iPhone 6S or later, Galaxy S6 or later, Google Pixel and Moto Z2 Play. You can check T-Mobile's Magenta Friday page for the full list.

If you open up a new line without trading in a phone, you can get a free T-Mobile Revvl 2 (or Revvl 2 Plus for $84).
