However, many users face the problem: after buying a used phone or a self-reset, the system requires you to enter this data, and it is not at hand.

In this article, we will discuss in detail what Xiaomi activation data is, in which cases they are required, and most importantly, how to obtain them by legal means without the risk of blocking the device.

What is Xiaomi Activation Data and Why You Need It
