The foundational service category of EU telecom regulation, defined in Article 2(4) of the European Electronic Communications Code (EECC). It covers any service normally provided for remuneration over electronic communications networks, and being classified as one is what pulls a service into the EU’s telecom rulebook.
The Three Branches
- Internet Access Services (IAS): Connectivity to the open internet: fixed broadband and mobile data.
- Interpersonal Communications Services (ICS): Services enabling direct exchange between people, from phone calls and SMS to chat apps, split into number-based and number-independent subcategories.
- Signal Transmission Services: Pure carriage of signals, such as Machine-to-Machine (M2M) connectivity and broadcast transport.
Why the Definition Was Expanded
Before the EECC, EU telecom law effectively regulated only traditional carriers, while Over-the-Top (OTT) apps delivering functionally identical communication escaped it entirely. The 2018 recast rebuilt the definition around what a service does rather than how it is delivered, bringing messaging and calling apps into scope alongside the networks they ride on.
Why It Matters
Whether a product is an ECS determines its regulatory perimeter: security and incident-notification duties, consumer-protection and contract rules, emergency-services access, and lawful-intercept obligations. For SaaS and CPaaS (Communications Platform as a Service) providers, adding a chat or calling feature can quietly cross that line, turning a product decision into a compliance program.
