Plus Odkup is a diagnostic application designed for customers of Digital Care's partner Polkomtel. It provides a user-friendly interface for assessing the condition of devices accurately. The app automatically identifies the device's make and model and conducts a series of tests on essential features like calling, Bluetooth, touch screen, and face recognition.

Customers can receive a precise valuation for their device and the best trade-in value. Upon accepting the offer and completing the order, the device will be collected, verified, and a voucher will be generated. This voucher can be used to avail services or purchase devices offered by Polkomtel.
