Carso Global Telecom
Mexican telecommunications holding company that was acquired by América Móvil in 2010.
Last updated August 31, 2026
Overview
Carso Global Telecom was a Mexican telecommunications holding company associated with businessman Carlos Slim Helú and the Grupo Carso conglomerate. It was established in 1996 through a spin-off from Grupo Carso, creating a separate corporate vehicle for telecommunications assets and related investments. Rather than operating primarily as a consumer-facing brand, the company functioned as a holding structure whose subsidiaries supplied fixed-line, mobile, data, internet, corporate communications, and other telecommunications services. The company's portfolio included Telmex, one of Mexico's principal fixed-line and broadband operators, and Telnor, which served northern Mexico. Its broader group of companies also included Multimedia Corporativo, Global Telecom, Empresas y Controles, Technology and Internet, The Telvista Company, MTN, and Carso Telecom B.V. These holdings gave Carso Global Telecom exposure to telecommunications infrastructure, network services, customer-contact operations, technology-related activities, and international investments. The exact operational relationship among the listed subsidiaries varied, but the portfolio reflected the wider expansion of Slim's telecommunications interests beyond a single national fixed-line carrier. Carso Global Telecom was part of a broader effort to organize and consolidate telecommunications assets controlled by Slim's business group. Its importance lay less in a standalone retail identity than in its role as a corporate ownership and investment platform. Through its subsidiaries, it participated in the development and management of communications networks and services in Mexico and other markets connected to the group's Latin American activities. In 2010, América Móvil acquired Carso Global Telecom in a transaction reported at approximately $17.6 billion. The purchase formed part of a larger plan, reported at roughly $21 billion, to consolidate Slim's telecommunications holdings in Latin America under América Móvil. The transaction effectively ended Carso Global Telecom as an independent corporate entity and placed its telecommunications assets within América Móvil's organizational structure. Jaime Chico Pardo served as chief executive officer and president of the board during the company's final period. Following the acquisition, Carso Global Telecom ceased to operate as an independent holding company, although many of the businesses and assets associated with its portfolio continued within the acquiring group's telecommunications operations.
History
Carso Global Telecom emerged in 1996 when telecommunications assets were separated from Carlos Slim Helú's Grupo Carso conglomerate. The spin-off created a dedicated holding company for telecommunications interests at a time when Slim's business group was organizing and expanding its communications portfolio. Carso Global Telecom was not principally positioned as a consumer brand with a single product line. Instead, it owned or controlled a collection of operating companies that delivered telecommunications and related services. Its most prominent assets included Telmex and Telnor. Telmex provided fixed-line telephone, broadband, data, and related communications services in Mexico, while Telnor served customers in the country's northern regions. The holding company's portfolio also included Multimedia Corporativo, Global Telecom, Empresas y Controles, Technology and Internet, The Telvista Company, MTN, and Carso Telecom B.V. Together, these businesses represented a diversified collection of network, technology, international, and customer-service activities associated with Slim's telecommunications strategy. The company served as part of a wider corporate architecture linking Mexican telecommunications infrastructure with investments elsewhere in Latin America and related international markets. Its significance therefore came from the assets and subsidiaries under its control rather than from a distinct retail identity. The structure also allowed telecommunications businesses to be grouped separately from other Grupo Carso interests. In 2010, América Móvil bought Carso Global Telecom for approximately $17.6 billion. The acquisition was presented as part of a larger transaction and consolidation program valued at about $21 billion, designed to bring Slim's telecommunications holdings under América Móvil. This reorganization reflected América Móvil's role as the principal telecommunications vehicle for the group and increased the concentration of related assets within one operator. The acquisition brought Carso Global Telecom's independent corporate history to an end. Its subsidiaries and telecommunications assets were absorbed into or managed through the acquiring group's structure, while the Carso Global Telecom name ceased to represent an independent holding company. Jaime Chico Pardo was identified as the company's chief executive officer and chairman of its board during its final period.
