SIM Card Users Alert: These Violations Could Lead to 3 Years in Jail and a Fine of Up to ₹50 Lakh

Mobile users in India need to be careful about how SIM cards registered in their names are used. Allowing another person to use your SIM, obtaining a mobile connection through fraudulent documents, or tampering with a phone’s identification details could potentially result in serious legal consequences under India’s telecom laws.

According to a report by Mint, the Department of Telecommunications (DoT) has cautioned users against the misuse of SIM cards and other telecom identifiers. Certain violations covered under the Telecommunications Act, 2023 may attract imprisonment of up to three years, a fine of up to ₹50 lakh, or both, depending on the offence and the applicable legal provisions.

The warning is particularly important at a time when mobile connections are increasingly being misused in cyber fraud, financial scams and other illegal activities. Users should therefore ensure that every mobile connection issued in their name is either being used by them legitimately or has been properly reported if it is unknown or no longer required.

Be Careful Before Giving Your SIM Card to Someone Else

A SIM card is linked to the identity documents submitted when the mobile connection is obtained. Users should therefore avoid casually handing over a SIM registered in their name to another person, particularly when they have no control over how the number will be used.

The DoT warning also covers situations involving SIM cards acquired through false documents, fraudulent methods or the unauthorised use of another person’s identity.

Users should avoid selling, improperly transferring or providing SIM cards issued in their names to people who may use those connections for illegal purposes.

One particular concern is the use of so-called “mule SIMs”. Such connections can be used by fraudsters or criminal networks to facilitate cybercrime while attempting to distance themselves from the activity.

A person whose identity is associated with such a connection could consequently face scrutiny if the number becomes linked to unlawful activity.

Tampering With a Phone’s IMEI Can Have Serious Consequences

The government has also cautioned users against manipulating telecom identifiers such as the International Mobile Equipment Identity, commonly known as the IMEI number.

Every mobile handset is assigned a unique IMEI that helps identify the device on a telecom network. Users should not attempt to alter, erase or tamper with this identifier through unauthorised tools or methods.

Under the relevant provisions of the Telecommunications Act, 2023, tampering with prescribed telecom identifiers can constitute an offence.

The warning also extends to unauthorised manipulation of Calling Line Identification (CLI), the information used to identify the number associated with an incoming call.

According to the reported DoT advisory, offences falling under the relevant provisions can carry punishment of up to three years in prison, a fine of up to ₹50 lakh, or both. The exact penalty would depend on the nature of the violation and the legal provision applied in a particular case.

How to Find SIM Cards Registered in Your Name

Mobile users can take a simple precaution by checking how many connections are currently registered against their identity.

The government’s Sanchar Saathi platform provides a facility called “Know Mobile Connections in Your Name.” Through this service, users can view mobile connections associated with their identity.

If the list contains a number that you do not recognise, did not request or no longer need, the platform also provides a mechanism to report the connection.

This is especially useful because an unknown mobile connection registered using your identity could potentially be misused without your knowledge.

You Can Also Verify Your Mobile Phone’s IMEI

Sanchar Saathi offers another useful feature for checking the authenticity of a mobile handset.

Through the “Know Mobile Handset Genuineness” facility, users can verify information associated with a handset’s IMEI. The service can provide details such as the phone’s brand, model and manufacturer information.

Checking the IMEI can be particularly useful when purchasing a used or second-hand smartphone, where buyers may want to verify the handset’s identification details before completing the transaction.

What SIM Card Users Should Do

Mobile subscribers should periodically review the connections registered in their names and immediately report any unfamiliar numbers. They should also avoid sharing or transferring SIM cards informally, providing their identity documents to unknown people for obtaining connections, or using software and devices designed to manipulate telecom identifiers.

If you have previously given a SIM registered in your name to another person, it is sensible to check whether that connection is still active and whether it is being used legitimately.

The important point is that a mobile number is more than just a means of making calls or accessing the internet. Because SIM registration is linked to an individual’s identity, misuse can potentially create financial, cybersecurity and legal problems.

Regularly checking your registered connections through Sanchar Saathi and promptly reporting unfamiliar numbers can help reduce the risk of your identity or mobile connection being misused.
