With mobile fraud, fake SIM registrations, and smartphone theft rising across India, securing your device and identity is no longer optional—it’s essential. To help citizens stay protected, the Government of India has launched the Sanchar Saathi app, a mobile-security platform developed by the Department of Telecommunications (DoT). The Sanchar Saathi app lets you verify your phone’s authenticity, see all SIMs issued in your name, report suspicious usage, and even block a lost or stolen mobile so it can’t be misused.
Originally launched as a portal and later as a mobile app in January 2025, Sanchar Saathi has quickly become a central tool in India’s digital safety ecosystem. Recent government directions now require new smartphones sold in India to come with the Sanchar Saathi app pre-installed, further expanding its reach. If your device doesn’t have it yet, downloading and setting it up is quick and easy.
What Is the Sanchar Saathi App and Why It Matters
Sanchar Saathi is a citizen-focused telecom safety app and portal created by the DoT to help users protect themselves from mobile-related fraud and misuse. It connects with the Central Equipment Identity Register (CEIR), a national IMEI database, to track and manage legitimate devices.
With the Sanchar Saathi app, you can:
- Check if a mobile handset is genuine, blacklisted, or reported stolen using its IMEI number (Know Your Mobile / KYM).
- View all mobile connections issued under your name to detect unauthorised SIM cards.
- Block your lost or stolen phone across all networks so it cannot be used with any SIM
- Report suspicious calls, SMS, and fraud attempts linked to your number.
This makes the Sanchar Saathi app a powerful all-in-one safety toolkit for every smartphone user in India.
Where to Download Sanchar Saathi on Android and iPhone
Even if your new phone doesn’t come with the Sanchar Saathi app pre-installed, you can download it easily from official app stores.

How to Install and Register on Sanchar Saathi
Once you’ve installed the Sanchar Saathi app, initial setup takes less than a minute.
Follow this simple step-by-step guide:
- Open the Sanchar Saathi app on your phone.
- Enter your mobile number when prompted on the registration screen.
- Receive the OTP (One-Time Password) via SMS on that number.
- Enter the OTP in the app to verify your identity.
- After successful verification, the main dashboard will unlock, giving you access to all features like KYM, SIM check, and device blocking tools.
Make sure the number you register with is active and in your possession, as you will need it for OTP verification and future security actions.
Key Features of the Sanchar Saathi App You Should Use
Once your Sanchar Saathi app account is active, you can start using its core security features. These are the most important tools every user should know:
1. Know Your Mobile (KYM)
The KYM feature lets you verify the status of any mobile phone using its IMEI number.
You can:
- Check if the device is genuine or cloned.
- See whether the phone has been blacklisted or reported stolen.
- Avoid buying second-hand phones that may be blocked or illegal.
This is especially useful when purchasing used smartphones from third-party sellers or marketplaces.
2. Check SIM Connections in Your Name
The Sanchar Saathi app can show you how many mobile numbers are currently registered with your identity (ID proof).
This helps you:
- Detect unauthorised SIM cards issued in your name without your knowledge.
- Identify SIMs you no longer use and request disconnection from your operator.
- Reduce the risk of fraud using fake or excess connections linked to your ID.
3. Block Lost or Stolen Phones
If your phone is lost or stolen, Sanchar Saathi lets you block the device at the IMEI level via the CEIR system, making it unusable across all Indian networks.
General steps to block a phone:
- File a police complaint (FIR) for the lost or stolen device and keep a copy of the report.
- Get a duplicate SIM for the affected number so you can receive OTPs.
- Use the Sanchar Saathi app or portal to submit a block request by providing IMEI, device details, and your ID information.
- Once processed, the IMEI will be blocked, and the phone will not work even if someone inserts a new SIM.
You can later use the same portal or app to unblock the device if it is recovered, using your Request ID.c
Pre-Installed Sanchar Saathi on New Smartphones
To strengthen digital safety across the country, the DoT has issued a directive requiring all new smartphones sold in India to come with the Sanchar Saathi app pre-installed.
Key points from the directive:
- Manufacturers and importers have 90 days to ensure pre-installation on all devices manufactured or imported for sale in India.
- The app must be clearly visible and accessible during first use or device setup
- For phones already in the sales pipeline, companies must push the app via software updates.
The government has clarified that while Sanchar Saathi app will be widely deployed, users are free to decide how actively they want to use it for their own protection.
Tips to Use Sanchar Saathi Safely and Effectively
To get the most out of the Sanchar Saathi app:
- Immediately check SIM connections in your name when you first log in.
- Use KYM before buying any used phone to avoid blacklisted or fake devices.
- If your phone is stolen, act fast—file an FIR, get a duplicate SIM, and submit a block request through the app or portal.
- Do not share your OTP or Sanchar Saathi login with anyone else.
- Regularly review your dashboard for any suspicious changes or new connections.
