Most of T-Mobile's biggest discounts require a trade-in of an eligible device. However, there are several no-trade-in promotions available — especially for adding lines or switching plans. We surface both so you can compare.
Most deals deliver savings as monthly bill credits over 24 months. If you cancel or change plans before that window closes, the remaining credits stop — meaning you'd still owe the full device cost.
Usually not. T-Mobile generally allows one device promotion per line, though plan discounts (like military or 55+) can sometimes be combined with device deals. We flag when stacking is possible.
We check for new and expiring promotions regularly. T-Mobile updates deals frequently — sometimes weekly — so we aim to keep this as current as possible.
