The amount you'll get for a Samsung Galaxy S III depends on the device model, storage, cosmetic condition, carrier lock status, and whether security protections (like Factory Reset Protection) are active. ecoATM calculates offers from real-time market data and pays instant cash at the kiosk, and its pricing often beats carrier trade-in values. Your final offer will reflect the phone's condition and current market price.

Start by getting an online quote or locking in a price in the ecoATM app, then prepare your phone for sale and bring it to a nearby kiosk. At the kiosk ecoATM will examine and run diagnostics on the device, give you an offer, and you can accept or decline that offer. If you accept, ecoATM pays instantly in cash or offers digital payment via PayPal or Venmo.

Yes — ecoATM accepts Samsung Galaxy S III devices with cracked screens, dents, faulty batteries, water damage, and other problems, though condition affects the offer you receive. If a kiosk cannot make a cash offer for resale, ecoATM will recycle the device responsibly so it doesn't end up in a landfill. Even damaged phones can often earn you some value through ecoATM.

ecoATM accepts both carrier-locked and unlocked Samsung Galaxy S III phones, but carrier-locked devices typically receive a lower offer because lock status affects resale. A carrier-locked phone means it's tied to a mobile provider, and that can reduce the device's resale market and value. ecoATM will still evaluate the phone and make a competitive cash offer based on its condition and market demand.

Back up any data you want to keep, sign out of your Google account, and disable Factory Reset Protection before you visit an ecoATM kiosk. Remove your SIM and any microSD card, then perform a factory reset unless you're using the ecoATM app to lock in an offer beforehand. ecoATM recommends charging the device because phones that power on typically earn more.

You should factory reset your Samsung Galaxy S III before selling to protect your data, and ecoATM also wipes devices that power on using specialized data-erasing tools before resale. ecoATM follows data-wiping procedures to remove personal information and protect sellers, and those measures are applied prior to refurbishment or recycling. Taking the preparatory steps above plus ecoATM's wiping gives two layers of protection for your information.

Devices that are in good enough condition are refurbished and resold to extend their useful life, while phones that can't be resold are recycled through certified e-waste partners. ecoATM works with responsible recyclers and follows industry recycling standards so materials are recovered and toxic components are kept out of landfills. This approach helps keep electronics in use longer and reduces environmental harm.

The trade-in value of your Samsung Galaxy S III is not a fixed number because ecoATM prices the exact device in front of the kiosk. It looks at storage, carrier lock status, screen and battery condition, whether it powers on, and any Samsung or Google account locks, then gives you a real offer you can accept or decline. You can start with an online estimate, but the final value is confirmed after the in-person diagnostic, with payment available right away in cash or through Venmo/PayPal where available. To help the process go smoothly, back it up, remove your Samsung and Google accounts, and charge it before visiting the kiosk.
