As of October 14, 2026, Techtree pays up to $45 for an OnePlus 8T 5G in good condition (light wear, fully working). The price is locked for 21 days from your quote, shipping is free, and payment goes out 1 to 2 business days after inspection.
Which OnePlus 8T 5G is this page for?
OnePlus 8T 5G: released October 2020, chip Snapdragon 865, display 6.55", storage options 128GB / 256GB, RAM 8/12 GB. Techtree buys every configuration listed in the price table, on Unlocked, T-Mobile, Verizon.
Can I sell an OnePlus 8T 5G with a cracked screen or other damage?
Yes, as long as it powers on and works. One issue, such as a cracked screen or a dented frame, is our Minor Damage grade: as of October 14, 2026 Techtree pays up to $21 for an OnePlus 8T 5G in that condition. A device that does not power on cannot be quoted.
Is a locked OnePlus 8T 5G worth anything?
Not to Techtree: every quote requires the device to be free of activation lock (Find My or Factory Reset Protection), carrier finance locks and blacklisting, and the wizard will not make an offer otherwise. Sign out of your accounts, turn the locks off, pay off the device and remove your data before you ship, and the full price applies.
Does the carrier change what an OnePlus 8T 5G is worth?
Yes. The price table is for Unlocked. On other carriers the same device fetches: T-Mobile up to $55, Verizon up to $35. Pick the carrier in the wizard for the exact figure.
What's the best way to sell my used phone?
You can list it on a marketplace, trade it in with a carrier, or use a buyback service like Techtree. A buyback gives you a locked, upfront price with free prepaid shipping and no listing hassle or fraud risk, usually the fastest and safest option.
Does carrier or storage affect my offer?
Yes. Unlocked phones are worth the most, and higher storage tiers earn more. We ask for both during the quote so your price reflects your exact configuration.
Should I factory reset my phone before sending it?
Yes. Back up your data, sign out of your account, turn off activation lock and Find My, remove your SIM, and erase the phone before you ship it.
When is the best time to sell my phone?
Usually right before a new model launches, since older models hold value best before the announcement. Lock your quote now and you have 21 days to ship.
Other OnePlus phone models we buy
Same instant quote, free shipping and 21-day price lock on every model.
