The amount you'll get for your Apple iPhone 11 Pro Max depends on the device's condition, storage size, carrier lock status, and whether security features like Find My are disabled. ecoATM gives an instant cash offer at the kiosk (and you can get a price estimate online before you go), and in many cases ecoATM's cash offers are competitive with — and often beat — carrier trade-in values. Final offers are determined by the kiosk's diagnostic check of your device.

Start by getting a free online quote to see a price estimate, then back up your data and prepare the phone for sale by disabling Find My and signing out of your Apple ID. Find a nearby ecoATM kiosk (there are thousands nationwide, including inside major retailers), connect your Apple iPhone 11 Pro Max so the kiosk can run diagnostics, and then accept or decline the instant cash offer on the screen. If you accept, ecoATM pays you on the spot via cash, Venmo, or PayPal depending on kiosk options.

Yes — ecoATM accepts Apple iPhone 11 Pro Max devices with cracked screens, dents, faulty batteries, and other damage, though condition affects the offer amount. If the kiosk cannot make a cash offer because the device has no resale value, ecoATM will recycle the device responsibly to keep e-waste out of landfills. ecoATM will always tell you the result before you complete the transaction.

You can sell a carrier-locked Apple iPhone 11 Pro Max to ecoATM; ecoATM buys both locked and unlocked devices. Carrier-locked devices typically receive a lower offer than unlocked ones because locks and security settings limit resale options, but ecoATM will still run diagnostics and make a competitive cash offer. Disabling locks and removing security features when possible helps maximize your price.

Before you go to a kiosk, back up your data, sign out of your Apple ID, disable Find My for Apple devices, remove your SIM card, and perform a factory reset so your personal information is erased. ecoATM's how-to-prepare guidance recommends these steps to ensure the device can be tested and resold if appropriate. Completing these steps makes the kiosk process faster and helps you get the best offer.

You should factory reset your Apple iPhone 11 Pro Max before selling to remove personal data, and ecoATM also performs additional data wiping on devices before resale. ecoATM advertises secure data handling and wipes devices to industry standards prior to refurbishment or resale, so personal information is removed as part of ecoATM's processing. Following the pre-sale steps (backup, sign out, disable Find My) gives you the most protection.

Devices that are in good condition are refurbished and resold, extending their useful life and keeping electronics in circulation. Devices that can't be resold are recycled through ecoATM's responsible e-waste partners, which helps keep toxic materials out of landfills. ecoATM promotes device re-commerce and environmentally friendly handling of used phones and tablets.

The trade-in value of your Apple iPhone 11 Pro Max 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 Apple iPhone 11 Pro Max 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.
