Introduction to Telecom Services

Telecommunication services, commonly referred to as telecom services, form the backbone of modern communication. They enable individuals and organizations to transmit data, voice, and video over distances, connecting people and businesses across the globe. As technology has evolved, telecom services have transitioned from simple voice calls to a complex system encompassing mobile networks, broadband, satellite communication, and cloud telephony.

In today’s digital era, telecom services are more than just a convenience—they are a critical infrastructure driving economic growth, enhancing global connectivity, and enabling new business models. Whether it’s a phone call between two friends or an international video conference, telecom services make it all possible.

Types of Telecom Services

Telecom services can be broadly classified into several categories. Each category serves a specific purpose and caters to different user needs.
