All Lenovo devices, particularly those with a high market share are subjected to the bad ESN Lenovo. If you happen to have it, it will prevent your device from accessing cellular network services such as SMS, Phone calls, and mobile data. This is a major headache for a lot of users, as it won’t be able to use any services provided by any wireless carrier unless you unlock it. Our main objective with this blog, it’s to share important information and show you how to get it unlocked in two main ways.
What is a bad ESN Lenovo?
ESN stands for Electronic Serial Number, and it is a unique number assigned to every mobile device. The ESN is used by wireless carriers to identify valid devices on their network, and it is mandatory by law to be printed somewhere in the hardware of your Lenovo phone.
How does it work?
Now that you have a more detailed concept of what the ESN is, you must understand that this number works the same as your ID does. As a way to discourage the reselling of fraudulently obtained devices, organizations like the Global System for Mobile Communications (GSM) allow wireless carriers to block service to devices that have been reported stolen, lost, outstanding balance, or have been blocked for abusive activity. It can also work under CDMA networks but it is a lot more limited as its usage it’s not as popular as a GSM network.
How to check the blacklist status
To check if your Lenovo phone has a blacklisted IMEI, you can do the following:
- Dial *#06# on your phone to display the IMEI number. Make a note of the IMEI number.
- Go to a website that allows you to check the status of the IMEI number, such as IMEI24 or IMEIpro
- Enter the IMEI number in the appropriate field on the website and click on “Check IMEI” or a similar button.
- 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:
- On your Lenovo phone, go to the “Settings” app.
- Scroll down and tap on “About phone”.
- Scroll down again and tap on “Status”.
- 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.
