The offer ecoATM makes on your Apple iPhone 6S depends on a handful of factors: the physical condition of the device, how much internal storage it carries, whether it's still tied to a specific carrier or fully unlocked, and whether any security features like Activation Lock are still turned on. ecoATM pays you in instant cash as soon as you accept the offer at the kiosk, and that payout often beats what major carriers hand out as a bill credit for the same trade-in. Getting a free estimate on the ecoATM website takes only a minute and gives you a solid baseline before you head in.

The first step is visiting ecoATM online to get a quick price quote for your Apple iPhone 6S. Next, prepare your device by backing up your data and doing a factory reset, then locate the nearest ecoATM kiosk inside Walmart or another participating retailer. At the kiosk, connect your Apple iPhone 6S so the machine can run a real-time diagnostic on its condition. Finally, review the offer on the screen and decide whether to accept the cash price or take your phone back.

Yes — ecoATM happily buys Apple iPhone 6S devices that show some wear and tear. Cracked screens, dents, scuffs, faulty batteries, and even phones that won't power on are all accepted, and the condition of your device will play a big role in how high the offer goes. If your Apple iPhone 6S is in such rough shape that ecoATM can't make a cash offer, the kiosk will still take it off your hands and ensure it's recycled responsibly.

Yes, ecoATM accepts both locked and unlocked Apple iPhone 6S devices, so there's no need to wrestle with your carrier before selling. A carrier-locked phone is simply one that's still tied to a specific carrier contract or payment plan, and because that limits the buyers who can use it, you'll generally see a slightly lower offer than you would for an unlocked version. Even with that adjustment, ecoATM still pays a competitive cash price on the spot, usually more than a carrier would give you in trade-in credit.

Before you head to the ecoATM kiosk, take a few minutes to back up your photos, contacts, and any other data you want to keep using iCloud or your computer. Sign out of your Apple ID and any Google accounts, disable Find My iPhone so Factory Reset Protection is turned off, and pop your SIM card out of the tray. Finish by running a factory reset through Settings to wipe the Apple iPhone 6S clean, and make sure the battery has a reasonable charge so the kiosk can complete its diagnostic.

Your data stays safe as long as you do your part before visiting an ecoATM kiosk: sign out of your Apple ID and Google account, disable Find My iPhone, and run a full factory reset on your Apple iPhone 6S so personal files are erased. On top of that, ecoATM applies a multilayered data-privacy process of its own and performs additional wiping on every device it receives before it ever goes back out for resale. Devices are processed to industry-standard wiping practices, so you can hand over your Apple iPhone 6S with confidence that your information stays protected.

Once you sell your Apple iPhone 6S to ecoATM, devices that are still in good working order are refurbished and resold, giving the phone a longer useful life and keeping it out of a drawer. Apple iPhone 6S units that can't be resold are routed through certified e-waste partners who break them down to recover precious metals and other reusable materials. Either way, the device stays out of the trash, helping stop toxic substances like lead, mercury, cadmium, and arsenic from leaking out of landfills and into the environment.

The trade-in value of your Apple iPhone 6S isn't fixed — it's based on factors like storage capacity, physical and functional condition, and whether the device is carrier-locked or unlocked. ecoATM gives you an instant cash offer at the kiosk (paid in cash or via Venmo/PayPal where available) rather than store credit, so you can see what your Apple iPhone 6S is really worth before you commit. Start with an online estimate, then complete a quick on-site diagnostic at a kiosk to lock in your final trade-in value.
