Why Sell Your Phone to GreenBuyBack?
GreenBuyBack has specialized in electronics buyback since 2014. Unlike many carrier trade-in programs that provide promotional credits or store credit, GreenBuyBack is designed for customers who want to sell their unwanted electronics for cash.
Our team provides white-glove service throughout the process, and GreenBuyBack has earned excellent ratings from customers on independent review platforms. We work to make selling your phone straightforward, transparent, and fast from your initial quote through payment.
We Buy Used and Broken Cell Phones
Your phone doesn't have to be in perfect condition to have value. GreenBuyBack purchases cell phones in a variety of conditions, including many devices with cracked screens, cosmetic wear, damaged components, or other issues.
When requesting your quote, choose the condition that most accurately describes your device. Your offer will depend on the phone's model, specifications, condition, and current market value.
Trade In Apple, Samsung, Google and More
We buy phones from many of the world's leading manufacturers. You can sell your Apple iPhone, sell your Samsung phone, sell your Google phone, or browse our complete cell phone buyback selection to find your device.
30-Day Cell Phone Trade-In Quotes
Planning to upgrade but aren't ready to send your old phone today? GreenBuyBack quotes are valid for 30 days, giving you time to purchase or activate your replacement phone before sending us your previous device.
Selling Multiple Cell Phones?
GreenBuyBack also purchases phones and other electronics in volume from businesses, organizations, resellers, schools, and other high-volume sellers. If you have multiple devices to sell, visit our bulk electronics buyback page for personalized assistance and volume pricing.
Don't See Your Phone?
We buy more devices than we can list individually on our website. If your phone or other electronic device isn't listed, submit a custom quote request and our team will review it for you.
