There are still a lot of people in the country who are using cellphones without an IMEI number. Connectivity to these cellphones was suposed to be blocked by telecom operators, as instructed by the authorities. DoT has now taken things more seriously by its decision of imposing a fine on a fortnightly basis on operators failing to do their duty.
Telcos were trying to find a way out of this, by providing a software which could generate the needed number for them. However, this has been strictly disallowed. Currently the new deadline, before which the operators are supposed to do the needful, has been set to 15th April.
