In Mexico, telecommunications has long ceased to be just an economic sector: it is the infrastructure on which bank transfers, emergency calls, telecommuting, e-government, logistics, education and entertainment depend.
Behind this connection are 12 key companies of various sizes and profiles.

As we can see, the telecommunications sector in Mexico includes private giants, international groups, government agencies and specialized infrastructure companies. Access to the Internet today is determined not only by the operator selling the service to the end user, but also by a complex chain: fiber optic networks, backbones, towers, data centers, software platforms and wholesale operators.
At the current stage of market development, three key contradictions are clearly visible:
- The pressure of streaming on traditional pay TV.
- Competition in the mobile and fixed Internet segments against the backdrop of exponential growth in data consumption.
- Strengthening the role of the state through its Altán and CFE structures in a market historically dominated by private capital.
It is the balance of these forces that will determine not only the structure of the industry, but also the price, quality and availability of communications for millions of residents of the country.
