The exact offer on your Samsung Galaxy S21 5G depends on its physical condition, internal storage size, carrier lock status, and any remaining security settings tied to your accounts. ecoATM pays instant cash the moment you accept, and our real-time market pricing often beats the trade-in credits that major carriers give you. To see your specific number, get a free online estimate first, then bring your phone to the nearest ecoATM kiosk for a final inspection-based offer.

Selling your Samsung Galaxy S21 5G at ecoATM is a quick five-step process. Start by entering your device details on ecoATM.com for an online price quote, then prepare the phone by signing out of accounts and factory resetting it. Next, find a nearby ecoATM kiosk inside Walmart or another major retailer, connect your Galaxy S21 5G to the machine, and let its automated diagnostic evaluate the condition. Once ecoATM shows its final offer, you can accept it for instant cash right on the spot or decline and take your phone back home.

Yes — ecoATM accepts Samsung Galaxy S21 5G devices with cracked screens, dents, faulty batteries, and other cosmetic or functional damage. The specific condition of your phone will affect the dollar amount of the offer, but a broken device is still welcome at the kiosk. If your damaged Galaxy S21 5G doesn't qualify for a cash payout, ecoATM will still take it and recycle it responsibly so the materials stay out of landfills.

ecoATM does accept carrier-locked Samsung Galaxy S21 5G devices, although the offer is typically a little lower than what you'd receive for a fully unlocked phone. A "carrier-locked" phone is one that is programmed to work only on a specific carrier's network, often because it's still being paid off or tied to an active installment plan. Even with that limitation, ecoATM still makes a competitive cash offer, and you'll get paid on the spot at the kiosk for your locked device.

Before you bring your Samsung Galaxy S21 5G to ecoATM, start by backing up your photos, contacts, and any other data you want to keep. Then sign out of your Google account in Settings, which also disables Factory Reset Protection so the next owner can set up the phone cleanly. Remove your SIM card and any memory cards, finish with a full factory reset from the General Management menu, and remember to bring a valid state-issued ID plus a charged battery to the kiosk.

Your personal data stays safe when you sell your Samsung Galaxy S21 5G to ecoATM as long as you factory reset the phone before dropping it off. Once a device reaches ecoATM's processing facility, every phone goes through an additional data-wiping step using industry-standard tools, so any leftover information is cleared before resale or recycling. Combined, your pre-sale reset and ecoATM's facility-level wipe keep your photos, messages, and account logins out of the wrong hands.

After you sell your Samsung Galaxy S21 5G to ecoATM, units still in good working condition are refurbished and resold, giving the phone a second life with a new owner. Galaxy S21 5G devices that are too damaged or outdated to resell are sent to certified e-waste partners who break them down and recycle the components responsibly. Either way, ecoATM keeps toxic materials like lead, mercury, and cadmium out of landfills, and the program has already diverted more than 28 million devices from the waste stream since 2009.

The trade-in value of your Samsung Galaxy S21 5G 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 Samsung Galaxy S21 5G 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.
