The amount you'll get for a Samsung Galaxy S10 depends on the device model, storage, cosmetic condition, carrier lock status, and whether security features are active. ecoATM pays instant cash at the kiosk and its pricing is backed by real-time market data, and it often beats carrier trade-in values. Your final offer will reflect the device's condition and current market pricing, so getting an estimate on the ecoATM site or app first can help set expectations.

Start by getting an online quote or locking in a price on the ecoATM app or website, then prepare your phone for sale by following the prep steps. Next, find an ecoATM kiosk near you and place your Samsung Galaxy S10 in the machine so it can run a diagnostic and assess condition. Finally, accept or decline the offer — if you accept, ecoATM pays instantly in cash or via PayPal/Venmo.

Yes — ecoATM accepts Samsung Galaxy S10 devices with cracked screens, dents, faulty batteries, water damage, or that won't power on, although condition affects the offer you receive. If the kiosk can't make a cash offer for resale, ecoATM will recycle the device responsibly to keep e-waste out of landfills. ecoATM evaluates every device and will give you the option to recycle rather than leave your device behind.

Yes — ecoATM buys both carrier-locked and unlocked Samsung Galaxy S10 devices, but carrier-locked phones typically receive a lower offer than unlocked ones because lock status affects resale value. "Carrier-locked" means the phone is tied to a specific wireless provider and can limit resale options, which is why ecoATM's offer may be reduced. Even so, ecoATM still makes a competitive cash offer you can accept on the spot.

Back up your data, sign out of your Google account, and disable Factory Reset Protection before you go to the kiosk so the device can be reset without being locked. Remove your SIM card and any external storage, then perform a factory reset unless you're using the ecoATM app to preserve an offer. ecoATM recommends bringing a charged device and a valid ID when you sell.

You should factory reset your Samsung Galaxy S10 before selling to protect your data, and ecoATM also evaluates and wipes devices using industry-standard data-erasing tools and procedures. ecoATM's process includes additional data wiping on devices that power on, and many phones are refurbished only after data has been securely removed. Taking the prep steps and using ecoATM helps protect your personal information before resale or recycling.

Devices that are in good condition are refurbished and resold so they get a second life, while devices that can't be resold are sent to certified e-waste partners for responsible recycling. ecoATM finds a second life for a large share of collected electronics and responsibly recycles the rest to keep toxic materials out of landfills. Selling to ecoATM helps extend device life and reduce electronic waste.

There is not one universal trade-in value for a Samsung Galaxy S10; two of the same model can get different offers. ecoATM considers storage, carrier lock status, screen and battery condition, whether it powers on, and any Samsung or Google account locks before it makes a final kiosk offer. If the phone is unlocked and ready to reset, the offer process is usually cleaner. Starting online gives you a ballpark estimate, and the on-site diagnostic gives you the number you can accept for instant payment.
