Hackers can use your SIM card.
You may not even be aware that someone else is using a SIM card in your name. In India, SIM card fraud is a frightening reality. You run the danger of financial fraud or identity theft since scammers frequently use your Aadhaar credentials to obtain mobile connections.
Under the TAFCOP (Telecom Analytics for Fraud Management and Consumer Protection) system, the Department of Telecommunications (DoT) has implemented a useful tool on its Sanchar Saathi portal to address this. You may see how many SIM cards are connected to your Aadhaar card simply by providing your mobile number.

Be aware of the SIM limit.
Connecting your mobile number to Aadhaar is required in India. In the majority of the country, you are permitted to have up to nine active SIM cards per person.
However, a growing number of people are unaware that they have additional, unauthorized SIMs linked to their Aadhaar due to fraud.
Have you discovered a questionable SIM? Take urgent action.
If you notice numbers that you are unfamiliar with:
- To report or disconnect fraudulent SIMs, mark them as “Not My Number.”
- If you no longer need them, mark them as such.
- Following that, the telecom provider will deactivate the numbers. Additionally, DoT will send you an SMS notice requesting that you decrease the number of active connections if you exceed the SIM card limit.

How to verify the SIMs that are connected to your Aadhaar
Here is a brief, detailed guide:
- Visit the website sancharsaathi.gov.in.
- Locate “Citizen Centric Services” on the front page, then select “Know Your Mobile Connections in Your Name.”
- Enter the captcha code and your 10-digit cellphone number.
- Use the OTP that was sent to your phone to confirm your identity.
- A list of all SIM cards issued with your Aadhaar will then appear.
Although SIM card fraud may occur, you don’t have to be a simple target. It only takes a few minutes to determine whether someone is abusing your Aadhaar with the DoT’s Sanchar Saathi tool.
