New Delhi: If you have been changing your mobile phone SIM card frequently for some reason or the other, this is a warning call.
The Department of Telecom (DoT) issued an advisory saying that mobile phone subscribers may be held liable if a SIM card procured in their name is found to have been misused for cyber fraud or other illegal activities.
DoT advised citizens to be cautious and avoid using mobile devices with tampered IMEI numbers, reported PTI.
Subscribers were warned against — buying or using procured or assembled devices like modems, modules, or SIM boxes which have configurable or tampered IMEIs; procuring SIM cards through fake documents, fraud, or impersonation; transferring or handing over SIM cards procured in their name to others who may misuse them.
“Citizens should be aware that using devices with tampered IMEI numbers, procuring SIM cards through fraudulent means, or transferring or giving their SIM cards to others who misuse them for cyber fraud can result in serious legal consequences. The original user may also be held liable as an offender in cases where SIM cards procured in their name are subsequently misused,” the DoT statement said.
DoT further advised subscribers not to use mobile applications or websites that modify Calling Line Identity (CLI) or other telecommunication identifiers.
Besides the Telecommunications Act, 2023, the Telecommunications (Telecom Cyber Security) Rules, 2024 prohibit any subscriber from altering the IMEI or using, producing or possessing equipment in which IMEI can be configured or changed or altered.
Citizens have been advised to verify IMEI details through the Sanchar Saathi portal or the Sanchar Saathi mobile app, which displays the device’s brand name, model and manufacturer information.
“The government has implemented the Sanchar Saathi initiative, providing digital tools for citizens to verify and secure their mobile connections. The government has put in place strict checks to prevent misuse of telecom resources and ensure a secure telecommunications ecosystem for all citizens,” DoT said.
There are provisions for stringent penalties for violation of the Telecommunications Act, 2023, such as tampering with telecommunication identifiers, including IMEI (International Mobile Equipment Identity) numbers of mobile handsets and other devices.
Penalties for any violation of the act include imprisonment for up to three years, fines up to Rs 50 lakh, or both.
