Illegal Use of Satellite Phones: Security Concerns and Regulations in India

Illegal use of satellite phones poses serious security challenges in India. Learn about regulations, reasons for restrictions, recent cases, and national security implications.

Context

Security agencies and the Directorate General of Shipping (DGS) have raised alarm over undeclared portable satellite communication devices — satellite phones and satellite-messaging units like Zoleo — being carried and used on ships in Indian waters.

How Satellite Phones Work

● Direct Satellite Connectivity: Satellite phones communicate directly with orbiting satellites instead of terrestrial mobile towers. This enables connectivity in remote oceans, deserts and border regions.

● Satellite Constellations: Systems like Iridium operate in Low Earth Orbit (LEO), using dozens of satellites to provide near-global coverage, including open seas.

● Signal Transmission Process: The phone transmits signals to a satellite → satellite relays to a ground gateway → routed to the public telecom network. If the gateway lies outside India, domestic monitoring becomes complex.

● Independence from Local Infrastructure: Unlike mobile networks, satellite systems do not depend on local telecom towers. This independence makes them useful for emergencies but difficult to regulate.

● Portable and Concealable: Modern satellite devices are compact, smartphone-compatible (e.g., messaging units), making concealment easier.

Satellite Messenger device

A satellite messenger is a device that sends messages through satellites instead of mobile towers, allowing communication even in remote or signal-free areas.

● E.g. Zoleo is a satellite-messenger device that pairs with smartphones and uses Iridium Communications satellite for messaging in no-signal areas.

Benefits of Satellite Phones and Messaging Apps

● Connectivity in Remote Areas: Satellite phones work beyond mobile network coverage, providing communication in oceans, deserts, mountains and border regions.

● Emergency and Distress Communication: They enable reliable SOS alerts during maritime accidents, natural disasters, ship breakdowns or rescue operations when terrestrial networks fail.

● Disaster Resilience: During cyclones, earthquakes or infrastructure collapse, satellite networks often remain functional, ensuring continuity of communication.

● Maritime and Aviation Safety: Ships and aircraft rely on satellite systems for navigation support, weather updates and emergency coordination under systems like Global Maritime Distress and Safety Systems (GMDSS).

Security risks

Monitoring blind spots: Without domestic gateways, messages via Iridium/Zoleo cannot be intercepted or locally traced in real time — hindering investigations of smuggling, trafficking or illicit communications.
Illicit coordination: Undeclared satellite links can be used to coordinate illegal transfers at sea, crew collusion, or remote control of illicit fishing/boarding operations. (Past maritime crimes globally have leveraged unmonitored comms.)
SAR confusion: Parallel channels may generate false distress signals or delayed authenticated alerts, complicating Search & Rescue (SAR) and Maritime Domain Awareness (MDA).
National security precedent: India has long restricted certain satellite phones after security incidents; travel advisories warn visitors against carrying such devices.
GMDSS compatibility: Encouraging certified shipboard Global Maritime Distress and Safety Systems (GMDSS) terminals and disallowing personal units in territorial waters is the common safety/security compromise

India’s vulnerability

Coastline & ports: India’s coastline is extensive (~7,516.6 km), with 13 major ports and 180+ minor ports — a large maritime domain to monitor.
Heavy traffic corridors: Indian waters sit on busy sea-lanes (Arabian Sea, Bay of Bengal), making maritime surveillance and interdiction challenging.
Maritime assets expanding: Government plans (e.g., exploring dedicated maritime satellite/transponder capabilities) signal intent to plug monitoring gaps

Way Forward

Tighten declaration: Mandatory e-declaration of all satellite devices before port entry; automated cross-checks with vessel manifests.
Gateway & monitoring capability: Accelerate domestic maritime satellite infrastructure (ground stations / regional gateways) or negotiated monitoring access with operators to enable lawful traceability. (IN-SPACe/SCC work in Ahmedabad is one step in national space capacity.)
Graduated enforcement: Issue warnings for first offences; fines/detention for repeat violations to avoid unduly penalising unwitting crews.
Crew welfare channels: Provide regulated shore-side crew-welfare comms facilities (satellite kiosks at ports) so personal safety/contacts can be maintained without illicit devices.
Industry engagement: Consult shipowners, seafarer unions, satellite operators and coastal security agencies to craft practicable rules.

Recent DGS measures and legal basis

● DGS draft MSN (Feb 2026) proposes: mandatory declaration of any satellite device onboard; sealing of undeclared devices; infringement notices and penalties for non-declaration or unauthorised use.

● Telecommunications Act, 2023 empowers regulators to control equipment, spectrum and impose penalties for unauthorised use.

● Merchant Shipping Act / Radio Comm. Rules 2025 provide maritime enforcement powers — port state control, detention, and crew/ship penalties. Parliament approved the Merchant Shipping Bill 2025 in 2025.
