AT&T Mexico Sale, Henox Subsea Cable Plan, and Colt Hollow-Core Fiber Trial

AT&T agreed to sell AT&T Mexico to Grupo Televisa and Fintech Holdings for $2 billion in cash; the business had about 24.7 million subscribers at the end of 2025 and generated roughly $4.65 billion in 2025 revenue, with the deal expected to close in early 2027 pending approvals. Henox IT and Data Centers proposed the Henox Crest coastal submarine cable linking Gujarat, Mangaluru, Kochi, Chennai and Visakhapatnam, combining subsea fiber, terrestrial networks, edge data centers and compute for AI and cloud services. Colt Technology Services, Network Planning Solutions and Relativity Networks completed a live hollow-core fiber deployment in central London that the companies say cuts latency by 30 percent.

AT&T's Mexican wireless unit, described as the country's second-largest mobile network, had about 24.7 million users at the close of 2025 and produced around $4.65 billion in 2025 revenue. Televisa and Fintech Holdings would share ownership, pairing mobile service with Televisa's fixed-broadband business. The sale, valued at $2 billion cash before adjustments and other contractual terms, is slated to finish in Q1 2027 if Mexican regulators approve. AT&T intends to direct future spending toward U.S. fiber, 5G and converged infrastructure.

Henox IT and Data Centers' proposed Henox Crest cable would link five Indian coastal locations: Gujarat, Mangaluru, Kochi, Chennai and Visakhapatnam. It would blend subsea and land-based fiber with edge data centers and compute capacity for AI and cloud traffic. Gujarat is envisioned as a western gateway to the UAE, Middle East, Europe and Africa; Visakhapatnam would connect with SubConnex toward Singapore, Malaysia and the U.S. West Coast. APTelecom is technical and commercial partner. Details like cost, length, capacity and launch dates remain unannounced.

Colt, Network Planning Solutions and Relativity Networks completed a live hollow-core fiber link between two Colt sites in central London. Relativity's ChronoCore was used; Network Planning Solutions handled installation, splicing, testing and validation. Hollow-core fiber carries light through air rather than glass, and the companies say it can cut latency by about 30 percent
