Legacy T-Mobile plans may may qualify for $830 trade-in offer

TL;DR

• T-Mobile is reportedly running a new $830 “any condition” trade-in offer (Promo R339) that began on October 2 and includes many older Android and iPhone models.
• The promo seems targeted mainly at legacy Simple Choice users, giving older plan holders a rare chance to qualify for a major deal.
• Unfortunately, it isn’t listed in the T-Life app for most users, and must be confirmed through a rep (call or text 611).
