Why Should You Block Your IMEI Number?

Why should you Block your IMEI Number

IMEI Blocking is a very handy way of protecting your device from being used illegally. It won’t block your device, but it will block your device from accessing the mobile network which will ultimately protect you.

Let me explain. Let’s suppose that you have lost your device, and now the thief has it. Now there are chances that the thief might sell it in the black market, but there are also chances that the thief might pass it to the criminals, and use it for illegal activity. It could be drug trafficking or even worse. So, when you block your IMEI, the mobile won’t be able to connect to the network.

So, blocking the IMEI of your stolen Device will protect you from getting into any legal trouble, and you can get the relief that it won’t be used for any illegal purpose.

How to Unlock a Blacklisted or Blocked IMEI?

Purchasing a used phone to save your money may not be that useful after all. Chances are good to own a mobile with blacklisted IMEI. And your purchase becomes useless without making calls, sending texts, and having no connectivity.

However, you may take the following methods into account to unlock the features.

Third-Party Services

There are many online as well as offline third-party services to unlock IMEI. It’s more like a universal solution to any kind of phone. You can check for premium apps from the App Store first. It only requires ESN (Equipment Serial Number) to remove the IMEI from the blacklist.

Contacting Carrier

Also, you can immediately contact the carrier to whitelist the phone’s IMEI. Carrier service should unlock the phone using private codes. But you may have to deliver the phone to the relevant authority/personnel to justify the action.

Switching Carriers

Another less-usable method concerns switching the carrier. Changing the carrier should unlock IMEI to make things work. However, it’s not exactly legal without the permission of the current carrier. So, you shouldn’t seek the solution unless it’s absolutely necessary.

Connecting to Wi-Fi may enable internet-based functions only. You can still manage to make online calls, texts, and other activities.

What Happens When IMEI Number Is Blocked?

What Happens when IMEI Number is blocked

In this section, I will explain what happens when the IMEI number is blocked. When you put forward your application to the carrier for blocking the IMEI, they initiate the process of blacklisting.

Most Carriers have a list where they can put this IMEI Number, and this list blocks the blacklisted devices from accessing the services of the carriers.

When the IMEI gets blacklisted, the lists update and this information propagates across all the carriers in the US. So, even if the thief tries to unlock the access to the network, then he/she won’t be able to do it unless the carrier, which blacklisted the number, does it.

If you have blacklisted the stolen device in the US, then the device won’t be able to access networks in the US. However, if the device is taken to other countries such as the UK, France, or any other country, then it will work there. Why? Because there is no global directory available at the time of writing this article, there are chances that countries might introduce it in the future.

You can also proceed further and report your Smartphone stolen to your local police department. They will also ask you to provide the IMEI or Serial Number, and you can formally launch your complaint. Some carriers might ask you to submit the police complaint along with the request to initiate the process of blocking IMEI.

What To Do If Phone Gets Stolen?

If your Smartphone has been stolen or lost, then you can take the following steps to ensure that your data is safe.

  • Start with launching your complaint to the local law enforcement agency.
  • Then proceed with blocking your IMEI Number so that it doesn’t get used for any illegal purpose
  • If your device is lost, then instead of filing a report or blocking IMEI Number, you can call on that number and see if someone picks it up.
  • If your device has been stolen and then make sure to launch a complaint and block IMEI.
  • On the iPhone, enable the “Lost Mode” and try to track your device. If there are no chances of recovery, then you can move to erase your device, which will erase all of your data.
  • On Android, you can use the “Find My Device” feature. You can use “Secure Device” which allows you to display your custom message and contact number on the lock screen. If you think that you won’t get your device, then you can use the “Erase Device” feature, which will remove all the data from the device.

Can A Stolen Phone Be Reset?

Yes, there are ways that can be used to reset the stolen phone. However, if they reset the stolen phone, they will be asked to enter the details of the account. On iPhone, you get the Activation Lock that gets enabled when you enable “Lost Mode” for your iPhone.

On Android, you get to enter the details of the previously used Google Account to proceed further.

Can A Phone Be Tracked If Turned Off?

When the device is turned off, it cuts off its communication with the nearby cell towers and GPS, which means you can’t track it.

Why Is The IMEI Of My Device Blacklisted?

If you have bought a second-hand smartphone and its IMEI number is blacklisted, then it means that it was either reported stolen or lost. In this case, if you use your number on this device, your carrier can suspend its services for you.

In a worst-case scenario, you can get reported to local law enforcement agencies. So, before buying the device, you can check the IMEI of the Device in IMEI Check services to ensure that it is not reported stolen or lost.
