The Ministry of Communications has issued guidelines to protect India’s mobile networks from IMEI tampering, a practice that allows devices to operate with false identities on telecom networks. The move comes as India’s wireless subscriber base has grown to over 1.2 billion users, making device security critical to the nation’s digital infrastructure. The guidelines clarify what constitutes illegal tampering and outline responsibilities for manufacturers, sellers, retailers and citizens.
What is IMEI and Why It Matters
Every mobile device has a unique 15-digit identification number called the International Mobile Equipment Identity (IMEI). This number helps telecom networks identify and track devices. The first eight digits, known as the Type Allocation Code, identify the device model and type. Dual-SIM phones carry two IMEI numbers, one for each SIM slot. Users can check their device’s IMEI by dialling *#06# on their phone.
Tampering with or misusing IMEI numbers allows criminals to hide the true identity of devices, complicating law enforcement efforts and creating security vulnerabilities in networks.
What is Now Illegal
Under the Telecommunications Act, 2023, it is unlawful to intentionally remove, change or alter a device’s IMEI number. It is also illegal to use, produce, sell or possess hardware or software designed to tamper with IMEI numbers. Violations attract imprisonment of up to three years, a fine of up to ₹50 lakh, or both. These are cognizable and non-bailable offences.
Manufacturers must register all IMEI numbers through the Device Setu portal before devices are sold or used. Importers must similarly register devices entering India. Retailers and resellers must verify that devices have valid, untampered IMEIs before sale.
What This Means for You
If you own a mobile phone, purchase devices only from authorised sellers and verify the IMEI using the Sanchar Saathi portal or by sending the number via SMS to 14422. Have repairs done only at authorised service centres. If your phone is lost or stolen, file a police complaint immediately and use the Sanchar Saathi app to block the device before your SIM is misused. Avoid buying second-hand devices without checking the government’s database of blacklisted or tampered phones. Do not procure devices with configurable IMEIs, obtain SIM cards fraudulently, or transfer SIM cards to others for misuse, as these actions carry serious legal penalties.
