Why should I get my new Samsung Galaxy S9 or S9+ at T-Mobile?

The new Samsung Galaxy is the fastest ever Samsung phone (based on LTE Cat. 18 device capabilities; actual speeds vary) and T-Mobile's Network is the fastest network ever, and at T-Mobile you get $360 off your new Galaxy S9 or S9+ (via 24 monthly bill credits) when you trade-in an eligible device. Why would you get it anywhere else?


Why is the iPhone X not included as an eligible trade-in device?

The iPhone X has a fair market trade-in value that is greater than the value of the promotion. So, you can save even more when you trade-in your iPhone X.


If I have JUMP! or JUMP! On Demand, can I still get this promotion?

JUMP! or JUMP! On Demand (JOD) customers may take advantage of the promotion as long as they trade in an eligible device that is paid-off, and purchase the new iPhone via EIP.


  • For JUMP!, you will need to pay off any remaining balance on your current device and do a Standard Trade-In (not a JUMP! upgrade).
  • For JOD you must elect to purchase your current leased device, then trade it in, and then purchase the Samsung Galaxy S9 or S9+ on EIP.
