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.
