SIM-Mistakes at this stage may result in the new owner being unable to activate the device or your banking data being in the wrong hands. In this article, we will analyze a detailed algorithm of actions that guarantees complete cleaning of the device and its readiness for operation by the new owner.

Before you erase all the contents of your memory, make sure that your contacts, photos, instant messengers and documents are securely stored. Backup is the only guarantee that you do not lose valuable memories or work files in the process of preparing for the sale.
The easiest way to save data is to use cloud storage Mi Cloud or Google Photos, which requires connecting to a stable Wi-Fi network, as the amount of information transferred can be significant.

Packaging and configuration
The final step is to pack the right box, have the original charger and cable, and make the lot look great, and if the box is still there, fold the phone and accessories carefully.
