    How to use IMEI to find a stolen or lost device

    It is worth noting that the chances of finding a lost or stolen gadget on your own are very small for two reasons:

    • No necessary equipment to search by IMEI: in order to find a stolen or lost device, you must have access to special equipment, as well as databases of all mobile operators in the country where the loss or theft occurred. It is thanks to this that you can determine the location of a lost device and a new one. mobile number, which is used by the gadget. The problem is that only law enforcement officials have access to equipment and information;
    • there is no access to information about the location of the device: absolutely all online services that the user can find on the Internet, as well as applications and programs supposedly for searching smartphones by IMEI, are completely ineffective. Only a cellular operator has the right to provide information about the location of devices at the request of the police, who accepted a statement from the owner about the theft. So you shouldn’t turn to online services and various applications to search for stolen or lost devices.

    The only sure way to find your gadget is to contact law enforcement agencies to file a theft report. The police, in turn, submit a request mobile operator to search for a device. Quite often this method leads to the discovery of smartphones and tablets.

    Search process lost devices happens with using IMEI-identifier

    Google service "Find my device"

    Google provides a service that can help you find your device if it is authorized in account Gmail.

    To quickly find your smartphone if you lose it, it is recommended to follow some tips:

    • fill out a business card with contact information on your smartphone or tablet. This will help, in case of loss of the device, the finder to find the owner of the device to contact him;
    • install the TheftAlert application on your device, which is designed to send an SMS message when changing the SIM card to a phone number specified in advance;
    • If you lose your device, immediately use one of the services (for example LoSToleN), which will allow you to add the IMEI of the gadget to the database of stolen devices. Also, in many similar services you can specify the amount of reward for return.

    Is it possible to remove IMEI

    Since IMEI is a very important identifier for any device and there is no way to deliberately remove it.

    But sometimes under the word " complete removal" also implies the following:

    • force the IMEI not to be displayed on the screen by dialing *#06#, which is possible with certain knowledge in the field of programming;
    • prohibit reading or accessing a memory cell. But what cannot be read, for example, via the RS-232 channel (computer port), can be read by the USB-Jig device (used in service centers to restore “bricked” Android devices) or, as a last resort, with a programmer (a device designed to write and read information in ROM - read-only memory);
    • forcing you not to release IMEI to the network upon request is problematic, but possible. But in this case, there is a high probability that service will be denied or the phone will never find the network.

    Each operator has an IMEI database, request individual number The radio module is required when registering on the network, and if the network operator does not receive a 16-digit number upon request, it will not allow the phone to use the network. From all that has been said above, we can conclude that “complete IMEI removal” is impossible.
