The Centre for Development of Telematics, better known as C-DoT, the technology arm of the Department of Technology (DoT), has recently launched the Sanchar Saathi portal that allows users to block and track their lost/stolen mobile phones across the country. C-DoT has been piloting the service in some telecom circles, including Delhi, Maharashtra, Karnataka and North East. Now, the service can be used across the country.

Users who have lost their phones can block their devices temporarily using the IMEI number of the device. Once the phone gets blocked, it will become unusable and will not work on any telecom service provider's network across India.

Users can follow the below steps to block the stolen/lost device using the Sanchar Saathi portal:

Unblocking the device

Once a device has been blocked, it won't work with any SIM card nationwide. This means if the thief has thrown the user's SIM card out and has tried to put his own SIM card in the device, the device won't operate.
