Back up, remove your Google and manufacturer accounts (to clear the factory-reset lock), remove your SIM/SD card, then factory reset. We wipe it again to NIST 800-88 standards and email you a Certificate of Data Erasure.

What if my Samsung S21 Ultra 5g is worth less after inspection?+

If our inspection changes your quote, we send photo evidence and give you 14 days to accept or decline. Decline and we ship your Samsung S21 Ultra 5g back free — we never silently accept a lower offer for you.
