DoT Issues Strict Guidelines: SIM Misuse Can Lead to Punishment for Subscribers
Government Warns Against Fake Documents, Tampered Devices, and Sharing SIMs with Others
New Advisory Highlights Legal Liability and Safety Measures for Mobile Users Across India
By Our Legal Reporter
New Delhi: November 28, 2025:
The Department of Telecommunications (DoT) has released a fresh advisory warning mobile subscribers that they may face legal consequences if SIM cards issued in their name are misused for cyber fraud, impersonation, or other unlawful activities. The guidelines, issued in late November 2025, are part of the government’s broader effort to curb telecom-enabled financial crimes and identity misuse.

Why the Advisory Now?
Cybercriminals are increasingly exploiting loopholes in SIM procurement. Many fraudsters acquire SIM cards using fake documents or borrow them from unsuspecting individuals. Once these SIMs are linked to scams—whether phishing, financial fraud, or threatening calls—law enforcement traces them back to the registered subscriber. This means that even if the subscriber did not personally commit the crime, they could still face liability.
Key Points of the DoT Guidelines
The advisory outlines several high-risk practices that citizens must avoid:
- Using fake documents to procure SIM cards.
- Sharing or handing over SIM cards to others who may misuse them.
- Using devices with tampered IMEI numbers or illegal SIM boxes.
- Employing caller identity masking apps or spoofing services, which can land users in legal trouble.
The DoT stressed that subscribers must take direct responsibility for safeguarding their SIM cards and mobile devices, as misuse traced back to their credentials can result in prosecution under the Telecommunications Act, 2023.

Legal Consequences
Under the new framework, individuals found guilty of SIM misuse may face:
- Prosecution under telecom laws.
- Fines and penalties for fraudulent procurement.
- Criminal charges if the SIM is linked to cyber fraud or impersonation.
The advisory makes it clear that ignorance will not be accepted as a defence. Subscribers must ensure that SIM cards registered in their name are used responsibly.
Safety Guidelines for Users
To protect themselves, DoT has issued a set of safety measures:
- Verify SIM ownership regularly using the Sanchar Saathi portal and app.
- Avoid lending SIM cards to friends, relatives, or employees.
- Report suspicious activity immediately to telecom providers.
- Check IMEI numbers of devices to ensure they are not tampered.
- Stay alert to phishing calls and messages, especially those requesting personal information.
These steps are designed to empower citizens to safeguard their digital identity and prevent misuse.
Broader Context
India has witnessed a surge in cyber fraud cases linked to SIM misuse. Fraudsters often use multiple SIM cards to run large-scale scams, including:
- OTP theft for banking transactions.
- Fake job offers and lottery scams.
- Impersonation of government officials.
By tightening regulations, the DoT aims to reduce such crimes and strengthen trust in the telecom ecosystem.
Expert Views
Cybersecurity experts have welcomed the advisory, noting that it places responsibility on subscribers while also pushing telecom companies to strengthen verification processes. According to them:
- The guidelines will deter casual sharing of SIM cards.
- They highlight the importance of digital hygiene in everyday life.
- They may reduce the burden on law enforcement by preventing misuse at the source.
However, experts also caution that awareness campaigns are essential. Many citizens are unaware of the risks of lending SIM cards or using tampered devices.
Impact on Businesses
For businesses, especially those issuing SIMs to employees, the advisory has major implications:
- Companies must maintain strict records of SIM usage.
- Any misuse traced to corporate-issued SIMs could result in liability.
- Telecom operators may face pressure to strengthen KYC (Know Your Customer) norms.
Global Comparisons
India’s move aligns with global trends:
- United States: Telecom regulators have cracked down on SIM swap fraud, holding carriers accountable.
- European Union: Strict GDPR rules require telecom companies to protect subscriber data.
- China: Operates one of the strictest SIM registration regimes, linking SIMs directly to national ID databases.
India’s advisory is unique in placing direct liability on subscribers, making it clear that responsibility cannot be outsourced.

Conclusion
The DoT’s new guidelines mark a turning point in India’s fight against cyber fraud. By warning subscribers that SIM misuse can lead to punishment, the government is sending a strong message: digital identity must be protected at all costs.
For citizens, the takeaway is simple: never share your SIM card, avoid tampered devices, and stay vigilant against fraud. For businesses and telecom operators, the advisory is a reminder to strengthen compliance and verification processes.
As India moves deeper into the digital age, safeguarding SIM cards is no longer just a matter of convenience—it is a matter of legal responsibility.
