That's a great question, hollyoh! Yes, you can pay off the full amount of the device. If you do decide to Edge Up however, you can Edge up after only paying off 75% of your device. May I ask why you are considering not Edging up this time?

Yes, but there is no financial advantage for doing so.

That would certainly depend on the person. If someone suddenly has the funds necessary to pay off the device but does not have the restraint to hold on to those funds without spending them on other goods/services over the duration of the Edge agreement, THAT is a financial advantage for doing so.
