How to find your lost/stolen mobile: With the aim to curtail the counterfeit mobile phone market and discourage mobile phone theft, protect consumer interest and facilitate law enforcement authorities for lawful interception, DoT intends to implement Central Equipment Identity Registry (CEIR) that connects to the IMEI database of all the mobile Operators. CEIR acts as a central system for all network Operators to share black listed mobile devices so that devices blacklisted in one network will not work on other networks even if the Subscriber Identity Module (SIM) card in the device is changed.
Know Your Mobile (KYM)
Through KYM, you can check the validity of your mobile device even before buying it. IMEI is written on the mobile packaging box. It could be found on the mobile bill/invoice. From your mobile you can check the IMEI number by dialling *#06#, IMEI number will be shown on mobile screen. If the status of the mobile is shown as Black-listed, duplicate or already in use, please avoid buying the mobile. KYM could be used through any of the following 3 methods.
| SMS | Type KYM <15 digit IMEI number> from your mobile and send the SMS to 14422. |
| KYM app | Download the KYM app from Play Store (for Android) or from App Store (for iOS). |
