International Mobile Equipment Identity or IMEI number is a unique number for every GSM, WCDMA and iDEN mobile phone as well as some satellite phones. We have already covered some important IMEI aspects on VirginTech, like how to check IMEI validity, how to find a valid IMEI number and how to find iPhone IMEI number. If you’ve not gone through them earlier, I would recommend you to take a minute to go through them.
How to block Lost/Stolen Mobile Phone using IMEI number:
Mobile phones have a IMEI number associated with them which you must note down at some secret location. The point that makes these IMEI numbers very important is that with the help of IMEI number you can impose a ban on your stolen or lost mobile phone.
If you have IMEI no of your stolen phone then report it to your local operator to block the device. This makes your network provider to put your phone’s IMEI no in a shared database called as an Equipment Identity Register (EIR) which reduces the threats of theft of handsets by enabling individual operators to prevent the use of stolen handsets in their own network.
Now to make the stolen phone inaccessible in other networks (service providers) also, your IMEI no is transferred to Central Equipment Identity Register (CEIR) which is a database of the IMEI numbers of blacklisted handsets. Once the device number is listed on CEIR, it wouldn’t work with any of the network provider.
