If you choose to pay the variance between the initial trade-in value and final trade-in value, your contact information would have been shared in advance by Samsung to our trade-in partner, for the purpose of sending the payment link to the email address you initially registered upon placement of your trade-in order.

For your security, you are advised not to share any other personal or payment information to the courier. You also need to ensure that you are accessing the correct payment link, and the details like your order number/IMEI and payment information are correct.
