If you have lost your mobile phone or if its stolen, then you can recover it or at least block it if you know the IMEI number of the phone.
The procedure to get back the stolen mobile phone will take some time so you must be patient. First you need to go to the police station in your area and file a FIR that your mobile phone is stolen.
Then take the copy of this FIR and the IMEI number of your phone and contact the service provider of your phone. They will then help you track the mobile phone location.
They will also block the mobile phone, making it useless until it is found. Once you find it, you can request your service provider to white-list it again.
This procedure will work even if the SIM card of the phone is changed because all service providers use the same blacklist database.
How this works? You probably already know that each mobile phone has a unique IMEI number. Whenever a mobile phone is switched on, this IMEI number is sent to Equipment Identity Register database. This database categorizes each phone in one of three categories: while listed, grey listed and black listed.
Your mobile service provider can block any mobile phone by putting its IMEI number in the black list. Once blacklisted, a mobile phone is useless as it cannot be used at all.
Your operator can also track the exact location of the mobile phone using its IMEI number using the Global Positioning System, thus helping you find the lost or stolen mobile phone. However, since a lot of phones get stolen these days, mobile operators will track a phone from its IMEI number only in the case of some special situation.
Note that when you contact your mobile service provider to block the mobile phone with its IMEI number, don’t forget to ask them to block your SIM also.
Also note that there are some specific apps that help you track lost or stolen mobile phones. For example, check the anti theft alarm for Windows phone. There are similar apps available for iPhone and Android phone as well and I will post reviews of these apps soon.
