What is IMEI and Why Is It Important?

The IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every mobile phone. This number plays a crucial role in identifying devices on mobile networks. For instance, even if a SIM card is changed, the IMEI remains constant, allowing authorities to track lost or stolen phones effectively.

Why Is the Government Focusing on IMEI?

Criminals often clone or tamper with IMEI numbers to disguise stolen or illegal devices. This practice not only threatens user safety but also hampers investigations and poses national security risks. For example, a stolen phone may be assigned a fake IMEI, making it appear as a completely different device on the network.

What Is the New Rule?

All mobile brands—including Apple, Samsung, Xiaomi, Vivo, Realme, and others—must pre-install the Sanchar Saathi app on every handset sold in India.

What Does Sanchar Saathi Do with IMEI?

The app significantly enhances device security by:

  • Verifying if a phone’s IMEI is genuine
  • Detecting cloned or duplicated IMEIs
  • Blocking stolen phones using IMEI
  • Allowing users to report IMEI-related fraud

For example, if two devices share the same IMEI, the Sanchar Saathi app alerts authorities and blocks potential misuse.

Responsibilities of Manufacturers

Manufacturers are required to:

  • Pre-install the app on all new devices
  • Submit IMEI compliance reports within 120 days
  • Ensure the app functions during device setup and is not restricted or removable

For instance, a new phone purchased in India should have the Sanchar Saathi app ready for use upon first boot.

What About Existing Phones or Unsold Stock?

Most phones already in stores may receive the app through software updates. The implementation for foreign-purchased devices is still being finalized. For example, a handset bought in the US may require a brand-specific update later.

Penalties for IMEI Tampering

Under the Telecommunications Act 2023, IMEI tampering is classified as a non-bailable offense. Penalties include:

  • Imprisonment of up to three years
  • Fines up to ₹50 lakh
  • Or both

Why Are Some Users Concerned?

Users have expressed concerns regarding data privacy and the mandatory nature of the installation. Some fear that skipping the update may affect their phone's functionality. For example, many are uncertain whether their device will operate properly without installing the app.

Government’s Reasoning

The government aims to build a safer digital ecosystem by reducing counterfeit devices, curbing IMEI fraud, and giving users more control over their device security.

Synopsis

India now mandates all mobile manufacturers to pre-install the Sanchar Saathi app to protect users from counterfeit devices and IMEI misuse. The app verifies device authenticity, blocks stolen phones, and identifies cloned IMEI numbers. Manufacturers must comply within strict deadlines under the Telecommunications Act 2023. While this move enhances consumer security, concerns remain regarding data privacy, updates for existing devices, and implementation for phones purchased abroad.
