In this article, we will discuss all the available security options, explain why direct blocking via IMEI through the site is not available to the average user, and provide a step-by-step algorithm for actions.

Why not just block your phone from IMEI on your website
Many users mistakenly believe that there is some secret website or program where you can enter an IMEI number and the phone will instantly disconnect from the network, a misconception born out of unscrupulous resources promising “miracle locking”, in fact, the management of the database of prohibited identifiers is the responsibility of mobile operators and government regulators, not the manufacturer of the gadget or its owner.
Technically, IMEI (International Mobile Equipment Identity) is a unique number that is transmitted to the base station when you register on the network. To block the device using this number, the operator must enter it into his Blacklist. On his own, the Internet user does not have access to the servers of operators to make such changes. Any sites that offer such a service for money or free are fraudulent.
⚠️ Warning: Never enter your own IMEI Attackers can use this number for cloning or other fraud, and you lose money or data.
However, there are legal ways to achieve lockdown, but they require interaction with the authorities, the owner must provide proof of ownership and the fact of loss, only then the operator can isolate the device from their towers. In parallel, blocking through service accounts (Mi and Google) creates a software barrier that is often more effective than network blocking, since it does not allow you to use your phone even with another device. SIM-card.
Google Find My Device Service
The first tool to use when you lose your Android device is a service from Google. If you have the Internet and geolocation enabled on your lost Xiaomi phone, and you have logged in to your Google account, you have the option of remote management. This method does not block IMEI, but allows you to lock the screen, display a message or completely erase data.
To access the features, you need to go to android.com/find from any other device (computer, tablet or phone friend), you will need to log in to the same Google account that was the main one on the lost gadget, the system will try to locate the device and will offer three main actions: “Call”, “Block” and “Clear”.
The lock feature allows you to set a new password for the screen even if it was not previously set, which will prevent access to apps and photos. A more radical method, Clear, will completely delete all data, returning the phone to factory settings. After this procedure, an attacker will not be able to access your data, but you will no longer be able to track the phone through Google.

- 🔒 Locking: Installation of new PIN-code or pattern lock remotely.
- 🗑️ Erasure: Completely delete all user data to protect privacy.

If the phone is offline or offline, Google will show the last known location.Enable notifications to receive an email when the device re-enters the network.
Blocking through Mi Cloud (Find Device)
For owners of Xiaomi, Redmi and POCO smartphones, the most effective tool is the manufacturer’s own ecosystem, Mi Cloud. Find Device works even deeper than standard Google tools, allowing not only to track, but also to lock the device at the system level, requiring a password from the Mi Account to unlock.
To use this method, go to the official i.mi.com website. Sign in using your Mi Account (the username and password you provided when setting up your phone). From the menu, select Find Device. If your smartphone is connected to the Internet, you will see it on the map and the list of available activities.
The key to locking through Mi Cloud is that you can activate the loss mode, and in this mode, the phone locks, and the screen displays the message you have given with the contact number. Most importantly, even after you completely flash or reset the settings (Hard Reset), when you turn on, the phone will require you to enter the password from the Mi Account, without it the device turns into a brick.
☑️ Checking security settings
It is important to note that for this feature to work, the service must be activated in advance. You can check this in the phone settings along the Settings path → Mi Account → Find the device. Make sure the switch is active. If this feature was disabled before loss, remote locking through Mi Cloud, alas, will not work.

What to do if your phone is off or without internet
The most difficult situation is when the stolen Xiaomi is turned off, in flight mode or in an area without network coverage, in which case remote commands sent via Google or Mi Cloud will not reach the recipient instantly.
In this case, your strategy should shift from “remote management” to “data protection and waiting.” Make sure you change the passwords of all the important accounts that were logged in on your phone: social media, banking apps, email, which will prevent an attacker from accessing your finances, even if they try to bypass the screen lock.
