There are some devices that require a down payment even with JOD. If the order is a pre order, there is no need to return your phone at the time of the order but once you receive the new phone.
For the 128 GB model.
The $81.99 Down payment is only available if your account meets specific requirements otherwise is till be $279.99. We cannot see your account here on a public forum but if you contact us, our care teams can check to see if you are eligible for that down payment option.
I was curious too I have the jump on demand and when jumping to to the note 8 was no problem it was zero down and now it's over 300 to jump to the note 9 and I dont know why. what's the point of jump on demand if I can only jump to a downgraded phone.
