Is your device fully paid for?
We need to confirm your Samsung Galaxy S25 Ultra is not currently under a contract or finance agreement.
How long is left on your contract or finance plan?
We can't accept contract phones
Unfortunately, we're unable to accept devices that are still under a contract or finance agreement. Until the device is fully paid off, it technically remains the property of your network provider.
If monthly payments are missed, the network can blacklist the device — making it unusable and worthless. We recommend paying off your contract in full before selling your device.

Please note
Since your device is still under a contract or finance agreement, we'll need proof that it has been fully paid off before we can process your payment. If proof cannot be provided, you may need to arrange for the device to be returned. We recommend settling your agreement before sending your device to us.
