    Two IMEI numbers for a dual-SIM phone

    Not confirmed: CEIR's list of prerequisites asks for the IMEI "if available", but the form makes the first IMEI compulsory. We found no official page saying where to find it. Look at the phone's box and purchase bill, or ask the shop that sold it.

    · Do them in order. Tick each one when it is done.

    If something goes wrong
    1. Do this now

      If money was taken through the phone, call 1930 at once.

      This cyber crime helpline is free and works round the clock, every day. The "Report a cyber fraud" guide says what to do next.

    2. Do this now

      From another phone, call your mobile company's customer care and ask them to block the lost SIM.

      Airtel: 121 or 198 from an Airtel number, 1800 103 4444 from any other number. Jio: 1800 889 9999 from a non-Jio number. Vi: 199, or "Block your SIM" on myvi.in.

      Your mobile company's customer care
      Not confirmed

      These numbers are from the companies' own websites (October 2026) and may change. We could not check BSNL's website: BSNL users, ask at a BSNL customer service centre.

      Sources: 11, 12, 13, 10

    3. Do this now

      Report the loss at a police station.

      Give the phone's brand, model and IMEI number, and the date and place of the loss. Take the complaint number and a copy of the complaint: CEIR needs both to block the phone.

      Where
      Police station
      Not confirmed

      The Andhra Pradesh Police citizen portal has "Submit a Complaint": you log in with your mobile number and an OTP, and you get a Petition ID. But no official page says whether it can be used for a lost phone, or whether CEIR accepts that number as the complaint number. Ask at the police station.

      Sources: 1, 6, 15

    4. Do this now

      Go to your mobile company's store for a new SIM with the same number.

      They will do Aadhaar e-KYC (fingerprint, iris or face) or digital KYC. The new SIM starts working only if your details and photo match the company's records.

      Where
      Your mobile company's store
      Not confirmed

      No official paper we read gives the charge for the new SIM; the company sets it. Ask at the store and take a receipt.

      Sources: 8, 9, 11, 13

    5. Do this now

      For the first 24 hours the new SIM cannot send or receive SMS.

      CEIR sends its OTP to this number, so wait 24 hours before the next step.

    6. Do this now

      On the CEIR site, fill in the form "Request for blocking lost/stolen mobile": the mobile numbers that were in the phone, its IMEI numbers, brand, model and price; the place and date of the loss; the state (Andhra Pradesh), district, police station, complaint number and a copy of the complaint; your name, address and identity card.

      Submit it with the OTP sent to the new SIM. You can also do this in the Sanchar Saathi app.

    7. Do this now

      After you submit, you get an 18-digit Request ID.

      Keep it safe, with the police complaint number and the IMEI number: you need them to check the status and to unblock the phone once it is found.

    8. Do this now

      On CEIR, check the status under "Check lost/stolen Mobile Request Status" with your Request ID.

      When it says "Blocking Request is successfully processed", your phone is blocked on every company's network and nobody can use it.

    10. Do this now

      On CEIR, open "Request for un-blocking recovered/found mobile" and leave "Un-Blocking Request" selected.

      Give the Request ID, the mobile number you gave for the OTP when blocking, and the reason ("Recovered by police" or "Found by self"). Submit it with the OTP.

      Where
      CEIR (Sanchar Saathi)
      Open the official page
      Not confirmed

      CEIR's un-blocking request does not ask for the police complaint. No official page we read says whether you must tell the police that the phone has been found. Ask at the police station where you complained.

      Sources: 2, 6

    11. Do this now

      When "Check Request Status" says "Un-Blocking Request is successfully processed", the mobile companies unblock the phone on their networks.

      After that the phone works again.
