Sign up for or add a line to any T-Mobile Experience Beyond plan and get the Samsung Galaxy S26 Ultra (256GB) for free with no trade-in required. You'll need to be cool with signing up to 24 months of service to cash in on the "free" aspect. T-Mobile will charge taxes and a $35 device connection fee. In total, you'll be saving $1,299.99 by getting the phone for free. If you want to go with the larger 512GB Galaxy S26 Ultra, you can still get a deal on the phone since T-Mobile will charge a monthly fee of $8.33.
