Can I pay loan off even if it is on someone's account?

So, I bought an iPhone 16 Pro from offerUp. It says no sim restriction (unlocked). The phone is not working with my E-sim. When I do imei check, it says the phone is backlisted due remaining loan payment/outstanding balance. My question is, can I call Verizon tomorrow to find out how much is left on the device and will I be able to pay it off if decide to do that? Thanks!
