Lost your phone? CEIR IMEI blocking, SIM protection and recovery records

A lost or stolen phone creates several separate problems: the handset, the SIM and the accounts accessible through it. CEIR IMEI blocking is not the same as blocking a SIM or protecting a bank account. Use the relevant official process for each concern and keep their reference numbers separately.
Secure the mobile connection and important accounts
Contact your telecom operator through its official lost-SIM process and ask how to suspend or replace the connection. Review account sessions and the recovery arrangements for important services you use. If you find an unauthorised financial transaction, report that immediately through the bank's verified channel and the appropriate cybercrime route rather than waiting for the handset process.
Make a short action log. Record when you noticed the loss, the last known location, when you contacted the operator and which protective steps were confirmed. If somebody else helps, give them the specific task required without handing over passwords or OTPs. Do not put banking credentials into a message sent by someone claiming to have found the device.
Record the loss and identify the handset accurately
Keep the phone's make, model and IMEI details, together with the relevant purchase or device record where available. Follow the police reporting process applicable to the circumstances and preserve the acknowledgement. Describe a loss or theft accurately; do not change the event merely to fit a form. Our police-reporting guide explains why an acknowledgement and an FIR are not automatically identical.
Use the official CEIR service
The Department of Telecommunications' CEIR page provides blocking, unblocking and request-status services. Enter through Sanchar Saathi or the official CEIR domain. The user manual explains the information and verification required, including arrangements concerning the number used with the lost handset.
Check every IMEI against your records before submitting. A dual-SIM device can have more than one identifier. Keep the completed request and the request ID. If the portal says a police request already exists for the device, follow the official instructions about that existing record rather than repeatedly submitting unrelated applications.
Know what blocking does not promise
The Government's description of Sanchar Saathi identifies CEIR as a system for blocking lost or stolen devices. It is not a promise of recovery by a particular date, nor does it replace police investigation. Account security and operator action should therefore continue alongside the device request.
For example, an acknowledgement that an IMEI-blocking request was accepted does not confirm that your email sessions were revoked or that a bank card was protected. Use your action log to check each task separately. Keep any later police communication with the original case reference instead of treating a device-status update as a new complaint.
If the phone is recovered
- Confirm that the recovered handset matches your device identifiers.
- Follow the official CEIR unblocking instructions and police directions.
- Retain the original request ID and recovery-related records.
- Check the operator's position concerning the replaced or suspended SIM.
- Review account security before returning the device to ordinary use.
Do not unblock a device solely because an unknown caller asks you to. Verify the situation independently. If money has been lost or a financial account was accessed, the financial-fraud guide explains a separate reporting process. This guide organises the steps without promising that blocking will locate or return the phone.
