Grading is a process for refurbished devices to ensure the quality and condition of the device. It is done on the basis of various factors like cosmetic conditions (scratches or marks) and internal conditions (performance). It gives the buyer a clear idea about what to expect from the smartphone they are purchasing.

Every device supplied by Telsim on behalf of our partner The Renewable Mobile Group has passed tests for all of the following functionality tests.
