The amount you’ll receive for a Samsung Galaxy J3 Luna Pro depends on the device’s model, storage, cosmetic condition, carrier lock status, and security settings like Find My/Factory Reset Protection. ecoATM pays instant cash at the kiosk and bases offers on real-time market data, and in many cases its pricing often beats carrier trade-in values. The kiosk’s final offer is determined after an on-device diagnostic that evaluates condition and market value.

Start by getting an online estimate or locking in a price in the app, then prepare your phone for sale by backing up and removing accounts. Next, bring your charged phone and ID to a nearby ecoATM kiosk, connect the device for the automated diagnostic, and review the offer the kiosk provides. If you accept, ecoATM pays instantly (cash or digital options); if you decline, you keep your phone.

Yes — ecoATM accepts devices with cracked screens, dents, faulty batteries, water damage, and models that won’t power on, though condition will reduce the payout. If a device can’t be resold for parts or refurbishment, ecoATM will recycle it responsibly so it doesn’t end up in a landfill. You’ll still get an offer when the kiosk can run its assessment; some severely damaged devices may be recycled instead of paid out.

Yes — ecoATM buys both carrier-locked and unlocked phones, but carrier-locked devices typically receive a lower offer because lock status affects resale value. Carrier-locked means the phone is tied to a carrier or hasn’t been fully unlocked for use on other networks, which can limit buyer demand. ecoATM will still run the same diagnostic and present a competitive cash offer based on that status.

Back up any important data, sign out of your Google account, and disable Find My / Factory Reset Protection so the kiosk can assess and wipe the device. Remove your SIM card, then perform a factory reset (or follow ecoATM’s app instructions if you’re using the app to lock in a price) before bringing it to the kiosk. A charged phone that powers on typically earns a higher offer with ecoATM.

You should factory reset your phone before selling to remove personal information, and ecoATM also uses data-wiping tools at its processing center to erase devices to industry standards where technologically possible. ecoATM recommends erasing your data yourself so you know your information is removed, and devices that power on are wiped before resale or recycling. While ecoATM performs additional wiping, taking these prep steps gives you the best protection for your personal data.

Devices that are in good enough condition are refurbished and resold to extend their useful life, while units that can’t be refurbished are recycled through ecoATM’s certified e-waste partners. ecoATM sorts devices to find a second life for many electronics and responsibly recycles the rest, helping keep toxic materials out of landfills. This approach both returns value to sellers and reduces environmental impact.

Your Samsung Galaxy J3 Luna Pro trade-in value comes down to the details, not just the model name. ecoATM checks things like storage, carrier lock status, screen and battery condition, whether it powers on, and any Samsung or Google account locks before showing the final offer on the kiosk screen. The online estimate is a useful starting point, but the kiosk diagnostic is what locks in the value, and you only sell if the offer feels right. If you accept, ecoATM pays on the spot by cash or, where available, Venmo or PayPal.
