FAQs
Limitations in the Previous Model of TRAI?
when a mobile handset is stolen, the user blocks the IMEI number by calling to the network operator service. This procedure blocks the phone but does not stop from using the phone. The service provider ensures that the network is not misused. But the lost phone was accessible after inserting a different SIM card. This was observed by the Telecom Regulatory Authority of India (TRAI) and the limitations associated with the existing model. Hence, the DoT launched CEIR with a revised model to track the lost or stolen mobiles even if the SIM cards are changed.
International Mobile Equipment Identity?
- Every phone or mobile broadband device has this unique 15 digit code that precisely identifies the device.
- Mobile phone manufacturers assign IMEI numbers to each device based on ranges allotted to them by the Global System for Mobile Communications Association.
- Dual SIM phones will have two IMEI numbers.
