The value of your HTC One M9 depends on condition, storage size, carrier lock status, and any active security settings like Factory Reset Protection. ecoATM gives an instant cash offer at kiosks (and can pay via cash, Venmo, or PayPal), and because ecoATM pays cash onsite it often compares favorably to carrier trade-in programs that issue store credit or bill credits. Bring your phone to a kiosk for a live evaluation to see the exact offer.

Selling your HTC One M9 at an ecoATM kiosk is a five-step process: get an online quote, prepare the device, find a kiosk, connect the device so the kiosk can run diagnostics, and then accept or decline the offer. ecoATM runs the diagnostics and gives you an instant offer at the kiosk so you can choose whether to complete the sale. If you accept, you get paid instantly and you can walk away with cash or choose an electronic payment option.

Yes — ecoATM accepts HTC One M9 devices with cracked screens, dents, faulty batteries, and other damage, though condition will affect the offer you receive. If a device cannot be resold, ecoATM will recycle it responsibly so it doesn't end up in a landfill. The kiosk will evaluate your device on arrival and tell you the offer or recycling option.

You can sell a carrier-locked HTC One M9 to ecoATM, but locked devices typically receive a lower offer than unlocked devices because they are harder to resell. A carrier lock means the phone is tied to a specific mobile provider until it is unlocked, and ecoATM will assess lock status during the kiosk diagnostic and give a competitive offer based on that status. ecoATM still buys both locked and unlocked devices and provides an instant offer.

Before you go to an ecoATM kiosk, back up any data you want to keep, sign out of your Google account, and disable Factory Reset Protection (FRP) if applicable so the kiosk can fully evaluate the device. Remove your SIM card, then perform a factory reset to erase personal information before you bring the phone in. These steps make the diagnostic faster and help ensure you get the most accurate offer from ecoATM.

You should factory reset your HTC One M9 before selling to remove personal data, and ecoATM also performs additional data wiping on devices before resale. ecoATM processes and wipes devices as part of its refurbishment workflow to protect seller privacy and prepare devices for resale. If you have concerns, back up important data and confirm you've signed out of accounts and disabled security locks before visiting a kiosk.

Devices in good condition are refurbished and resold, which extends their useful life, while devices that can't be resold are recycled through ecoATM's certified e-waste partners. That refurbishment and recycling model helps keep toxic materials out of landfills and supports eco-friendly re-commerce. ecoATM evaluates each device at the kiosk and routes it to the appropriate resale or recycling path after purchase.

The trade-in value of your HTC One M9 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 HTC One M9 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.
