How to check the blacklist status

Ways on How to Check the Blacklist Status

To check if your Lenovo phone has a blacklisted IMEI, you can do the following:

  1. Dial *#06# on your phone to display the IMEI number. Make a note of the IMEI number.
  2. Go to a website that allows you to check the status of the IMEI number, such as IMEI24 or IMEIpro
  3. Enter the IMEI number in the appropriate field on the website and click on “Check IMEI” or a similar button.
  4. The website will then perform a check on the IMEI number and display the result. If the IMEI number is blacklisted, it will indicate this on the website.

As this technology relies heavily on an open-sourced database, it is highly recommended that you perform this check on at least 2 different websites. It is common for users to get the wrong information as some websites might have some delays on their APIs.

Is there any other way to check your IMEI number?

If you want to double-check if the IMEI is correct, you will need to follow these steps:

  1. On your Lenovo phone, go to the “Settings” app.
  2. Scroll down and tap on “About phone”.
  3. Scroll down again and tap on “Status”.
  4. Here, you will see a section called “IMEI” or “IMEI information”. The number listed here is your Lenovo phone’s IMEI number.

It is important to note that the IMEI number is a unique 15-digit number that identifies your phone. It is used to track and block stolen phones, so it is important to know your IMEI number in case your phone is lost or stolen.
