Quick Checklist
| Step | Action |
|---|---|
| 1 | Block UPI and net banking through your bank |
| 2 | Ask UPI apps to block your account |
| 3 | Block your SIM |
| 4 | File police complaint and block IMEI on Sanchar Saathi |
| 5 | Erase data using Find My Device |
Step 1: Block UPI and Net Banking
Call your bank customer care from another phone and ask them to block UPI, net banking and cards linked to your phone. Also contact PhonePe, Google Pay or Paytm customer care through their official channels and request an account block.

Step 2: Block Your SIM
Call your telecom operator’s customer care or visit a store to block the SIM. This stops OTPs from reaching the person who has your phone. You can later get a duplicate SIM with the same number.
Step 3: Block the Phone IMEI on Sanchar Saathi
- File a police complaint (online or at the station) and keep the copy
- Go to sancharsaathi.gov.in and choose block lost / stolen mobile
- Enter IMEI, phone details and complaint details
- Submit to block the phone on mobile networks in India
You can find the IMEI on the phone box or purchase bill.
Step 4: Erase Your Phone Data
Use Google Find My Device (Android) or Find My (iPhone) to lock the phone or erase data remotely.
Phone Lost: Numbers to Keep Ready
- Your bank customer care number (written on the back of your debit card)
- UPI app support: PhonePe, Google Pay and Paytm help sections
- Your mobile operator customer care number
- National cyber fraud helpline 1930
- Your phone IMEI number (from the box or bill)
Save these in a note on another device or with a family member, so you can act quickly in a phone lost emergency.
How Sanchar Saathi Helps When Your Phone Is Lost
The Sanchar Saathi portal of the Department of Telecommunications lets you block a lost or stolen phone using its IMEI number. Once blocked, the phone cannot be used on any mobile network in India.
- File a police complaint and keep the copy
- Get a duplicate SIM for your number
- Open the Sanchar Saathi CEIR block request page
- Enter phone details, IMEI and police complaint number
- Submit and note the request ID
If you find the phone later, you can unblock it on the same portal using the request ID. Blocking the IMEI is the most important step after a phone lost or theft incident, because it makes the device useless for thieves.

Before It Happens: Set Up These Safety Features Today
The best time to prepare for a lost or stolen phone is before it happens. Spend ten minutes today on these settings, and your money and data will be much safer.
- Turn on Find My Device on Android or Find My iPhone on iPhone and test it once
- Set a strong PIN or password, not a simple pattern
- Enable app lock or biometric lock for UPI and banking apps
- Set a SIM PIN so a thief cannot use your SIM in another phone
- Write down your IMEI number by dialling *#06# and keep it safe
Also make sure your email account has two-step verification turned on with a backup method, such as a second phone number or backup codes. Your email is often the key to reset passwords for many other apps.
Back up your photos and contacts regularly to the cloud. Then, if you need to erase your phone remotely, you will not lose your important memories and data.
Finally, share your phone IMEI number and important customer care numbers with one trusted family member. In an emergency, they can help you block services quickly, even if you are travelling or stressed.
