The offer for your Samsung Galaxy S25 Ultra depends on its condition, storage capacity, carrier lock status, and security settings, so prices vary from one device to the next. ecoATM pays you instant cash on the spot, and we regularly beat carrier trade-in values because we believe you should decide how to use the money you earn from your old phone.

Selling your Samsung Galaxy S25 Ultra at ecoATM is simple and takes just a few minutes. First, get a free online quote on the ecoATM website to see what your device is worth. Next, prepare the phone for sale, then visit your nearest ecoATM kiosk inside Walmart or another major retailer. Once there, connect the device to the kiosk, let it run a quick diagnostic, and accept or decline the final offer on the screen.

Yes, ecoATM accepts Samsung Galaxy S25 Ultra devices with cracked screens, dents, faulty batteries, water damage, and other cosmetic or functional issues. The exact condition of the phone will affect the offer you receive, so more damage generally means a lower payout. If the kiosk can't make a cash offer for your specific device, ecoATM will still recycle it responsibly so it doesn't end up in a landfill.

ecoATM accepts carrier-locked Samsung Galaxy S25 Ultra devices, though a locked phone will usually receive a lower offer than an identical unlocked one. A carrier lock simply means the phone is currently tied to a specific provider like Verizon, AT&T, or T-Mobile and can't be used on other networks until the lock is removed. Even with that limitation, ecoATM still makes a competitive cash offer so you don't have to wait around for a trade-in.

Before bringing your Samsung Galaxy S25 Ultra to an ecoATM kiosk, take a few minutes to back up your data to the cloud or a computer so your photos and contacts are safe. Sign out of your Google account, disable Factory Reset Protection under your security settings, remove the SIM card, and complete a full factory reset to clear personal information from the device. A charged battery and a valid photo ID are also required at the kiosk.

Your privacy is protected in two stages when you sell to ecoATM. You should run a factory reset before selling, and then ecoATM performs an additional secure data wipe on every device as part of our multilayered process before resale. All wiping is done to recognized industry standards, so you can walk away from the kiosk knowing your personal information has been handled responsibly.

After you sell your Samsung Galaxy S25 Ultra to ecoATM, devices in good working condition are refurbished and resold, giving the phone a longer useful life. Devices that can't be resold are routed through certified e-waste recycling partners instead of being thrown away. This keeps toxic materials like lead and mercury out of landfills and puts fewer electronics into the waste stream overall.

The trade-in value of your Samsung Galaxy S25 Ultra 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 S25 Ultra 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.
