The amount you'll get for your Samsung Galaxy A31 depends on its model and storage, cosmetic condition, carrier lock status, and security settings like Factory Reset Protection. ecoATM pays instant cash at the kiosk and also offers PayPal or Venmo, and its pricing is backed by market data and often beats carrier trade-in values. Because offers change with market value and device condition, use the online estimate or the app to lock in a price before you go to a kiosk.

Start by getting an online estimate on ecoATM's website or app, then prepare your Samsung Galaxy A31 by removing accounts and backing up your data. Find a nearby kiosk at a participating retailer, place the device in the kiosk for a quick diagnostic, and then accept or decline the cash offer you're given. If you accept, ecoATM pays instantly in cash or via PayPal or Venmo on the spot.

Yes — ecoATM will accept a Samsung Galaxy A31 with cracked screens, dents, faulty batteries, water damage, or that won't power on; however, condition affects the offer amount. If the kiosk can't make a cash offer because the device has no resale value, ecoATM will recycle the device responsibly so it doesn't end up in a landfill. ecoATM evaluates every device and either refurbishes or recycles it according to e-waste standards.

You can sell a carrier-locked Samsung Galaxy A31 to ecoATM, but carrier-locked phones typically receive a lower offer than unlocked ones because lock status affects resale value. ecoATM buys both locked and unlocked devices and will still make a competitive offer based on the device's condition and market value. If possible, unlocking the phone before you sell may increase the payout.

Back up any data you want to keep, sign out of your Google account, disable Factory Reset Protection or "Find My" features, remove your SIM card, charge the device, and then factory reset it. Bringing a charged device and a government ID helps speed up the process at the kiosk. ecoATM also recommends turning off security features before you arrive so the kiosk can fully evaluate the phone.

You should factory reset your Samsung Galaxy A31 before selling to protect your personal information, and ecoATM recommends removing accounts and saved passwords beforehand. ecoATM additionally runs data-wiping procedures at its processing facility for devices that power on, but the company advises sellers to erase data themselves because complete erasure cannot be absolutely guaranteed in every case. Devices that can be wiped are cleaned to industry standards before resale or recycling.

Devices that are in good condition are refurbished and resold to extend their useful life, while devices that can't be resold are recycled through ecoATM's certified e-waste partners. ecoATM reports that a large share of collected devices find a second life and the rest are responsibly recycled, keeping toxic materials out of landfills. Selling your Samsung Galaxy A31 to ecoATM helps recover valuable materials and reduces e-waste.

What your Samsung Galaxy A31 is worth as a trade-in depends on the exact unit you bring in. ecoATM checks storage, carrier lock status, screen and battery condition, whether it powers on, and any Samsung or Google account locks and then shows the final cash offer after a short diagnostic. You are free to walk away if the offer is not what you had in mind, or accept it and get paid right there. If the phone is unlocked and ready to reset, the offer process is usually cleaner.
