Sundevice is a fast growing B2B marketplace of used smartphones and tablets. Founded in 2017, our aim is to provide all smartphone retailers access to high quality devices at a competitive price. Through our relationships with major actors in the used smartphone industry, we can guarantee consistent quality and inventory.

All of the devices we supply go through a rigorous testing and grading system. All phones must pass 28 key feature tests (see more about the 28 test) in order to be graded cosmetically (see more about grading). Once graded, based on trace of wear and scratches, the units are stored and ready to be shipped.

We constantly receive new inventory that is then tested and graded. As soon as new devices are ready to ship, they will reflect on our platform and will be accessible to our customers. Our platform is updated every 30 minutes with new price and new inventory level
