This only works if you have an eliginle trade-in device. For example, Samsung Galaxy S24 Ultra or S24 Plus (I tried these 2, they have the same trade-in value)
T-mobile is running the
Get up to $1,100 off with trade-in on an Experience More or Experience Beyond plan. Offer Id: Samsung Galaxy Promo with Trade (ID260641)
I was able to trade-in my Unlocked Samsung Galaxy S24 Ultra 256GB for S26 Ultra 256GB for $45.64 Monthly store credits for 24 months. After trade-in credits, the S26 Ultra 256GB ended up being $8.24/mo for 24 months or $201 total.
Costco T-mobile gives you a $100 Costco Gift card (waiting period 16 weeks after activation) for new device and waives the $35 connection fee. So after all said and done, my total was $1300 - $1100 (in credits) - $100 gift card = $100. The tax is added on the full phone price and is different per state requirements. My tax was $81.25.
