That is the info taken directly from T-mobile about the promotion. Based off everything I read I believe it may be feasible since your not combining it with other promotions like #getoutofred . However, to get a better answer that is more accurate I would call in and speak with a T-mobile rep or message the T-force team on Social Media. I say this because Jump is a little different from a normal EIP plan so I am not sure. Plus your not actually pre-ordering the phone at this point.
Thanks for replying. A minute ago I chatted with a representative and she told me that I can't do 2 trade in toward a new phone. So I can't JUMP my S8+ and trade in the S4 because doing a JUMP is a trade in also.
Hey, saelom! Thanks for asking this question -- I don't blame you for wanting to complete both a JUMP! and a trade-in to get the max benefit!
That said, I wanted to jump (no pun intended) in and let you know ASAP that the representative you spoke with is correct. Legally there is a 1:1 ratio of trade-in per purchased device, so your S8+ counts as the trade-in in this situation -- we wouldn't be able to add an additional trade-in to the transaction in order for you to qualify for the promotion. I wanted to make sure to confirm your info before you moved forward with your upgrade!
We've got a pretty active Official Samsung Galaxy S9 & S9+ Pre-order Thread where I know we addressed this question, but you're also welcome to post any others you might have! We're trying to steer all of our S9 questions and concerns there to keep things tidy and make it easier for Community members to locate a single resource when searching. I'm going to lock this thread, but if you have any additional questions about ordering an S9+, please feel free to ask away on the official thread! Thank you for posting.
