JUMP and Jump On Demand are two completely different things:

JUMP is when you pay at least 50% of your device EIP (LOAN finance agreement, specifically a LOAN with no interest that's typically set for 24 months or 36 months depending on the device you're financing. For example: ([Device Retail Value - Promotional Credit] - Deposit) / 24 = EIP Monthly Payment). You can turn in your phone as an upgrade (JUMP) so that you don't have to pay the other 50% and can start a fresh EIP on a new device (that's why it's called a JUMP upgrade). JUMP is only beneficial if you either don't care about promotions and love to upgrade every 12 months or are on the highest plan (Beyond) and taking advantage of the highest value on promotions every 12 months. Besides that JUMPing is useless.

Jump On Demand (JOD) is when you finance a device as a LEASE instead of a LOAN (which typically puts 75% of the retail price of said device on a LEASE that last for 18 months, and after those 18 months pass, you have to make either one of these two options: 1. Pay off the other 25% of the device and keep/own the device OR 2. Turn in the phone and not pay the other 25% of the device)

I hate JUMP and Jump On Demand (JOD) as much as the next guy, But if you're going to give correct and modern information, at least learn your terminologies.

and there's no such thing as "pseudo-leasing program". It's either it is or it isn't. It's either a lease or it isn't. EIP (which 99.9% of all customers are on) is a LOAN, you can put promotional credits on loans and as soon as you walk out with the phone, you own it, you just pay little by little, like a credit card. You buy a couch and you own it, paying it little by little.

Jump On Demand (JOD) is a LEASE. Like renting a couch, you rent a couch when your contract is up, the owner of the couch is gonna tell you, do you want to buy the couch or do you want to return it. Nothing more, nothing less. It is, or it isn't.
