Welcome to The Dealer Download, powered by RS&I.
AT&T spent more than a decade building a major wireless business in Mexico. Through acquisitions, network investments and years of competition, the company established an operation serving nearly 25 million subscribers.
Now AT&T has agreed to sell that business.
The October 13, 2026, announcement outlines a transaction with Grupo Televisa and Fintech Holdings valued at $2 billion in cash, plus additional contractual and contingent benefits.
That raises an interesting question: Why would a telecommunications company sell a business with such a large customer base?
The answer involves more than subscriber counts. It reflects the economics of competing in a challenging market and AT&T's broader decision to focus investment on expanding fiber and wireless connectivity in the United States.
What You’ll Learn in This Episode
Why AT&T Entered Mexico in the First Place
AT&T entered the Mexican wireless market in 2014 through its acquisition of Iusacell, followed by its purchase of Nextel Mexico in 2015.
Those acquisitions gave the company an established customer base and infrastructure it could use to build a larger wireless operation.
The strategy offered an opportunity to expand beyond the United States and compete in another major North American telecommunications market.
Building a Large Subscriber Base Takes Investment
AT&T invested billions of dollars into its Mexican operations over the following decade.
Expanding network coverage, improving service, acquiring customers and competing with established providers all required significant resources.
The company succeeded in building a wireless operation serving nearly 25 million subscribers.
But subscriber growth and financial performance aren't necessarily the same thing.
Why Nearly 25 Million Subscribers Weren't Enough
A large customer base can generate substantial revenue, but profitability depends on operating expenses, pricing, capital investment and competitive conditions.
AT&T Mexico faced a challenging market with strong established competitors, including Telcel.
Building and maintaining a modern wireless network requires ongoing investment, even when customer growth is strong.
Those economics help explain why a company might decide that a large operation no longer represents the best use of its capital.
What the $2 Billion Sale Includes
AT&T's agreement with Grupo Televisa and Fintech Holdings calls for $2 billion in cash, along with additional contractual and contingent benefits.
The transaction represents a major change in AT&T's international operations and gives the buyers an established wireless business with a significant subscriber base.
As announced, the transaction remains subject to applicable closing conditions, including regulatory approvals.
Until those requirements are satisfied and the transaction closes, AT&T Mexico remains part of AT&T.
AT&T Is Refocusing on the United States
The Mexico sale fits into a broader strategy centered on domestic fiber and wireless connectivity.
AT&T has outlined plans to reach more than 60 million fiber locations by the end of 2030.
That expansion involves acquisitions, construction partnerships, major supply agreements and new infrastructure financing arrangements.
Rather than continuing to invest in every market where it operates, AT&T is concentrating resources on the opportunities it believes best support its long-term strategy.
Fiber Is Becoming Central to AT&T's Growth Strategy
AT&T's fiber expansion isn't limited to building new infrastructure within its traditional wireline territory.
The company completed its acquisition of substantially all of Lumen's Mass Markets fiber business and announced a new fiber joint venture involving Gigapower, Forged Fiber 37, Global Infrastructure Partners and CPP Investments.
These moves support expansion into additional markets and demonstrate how AT&T is using multiple approaches to grow its fiber footprint.
For dealers, that means the geography of AT&T Fiber opportunities may continue changing.
Why Fiber and Wireless Convergence Matters
AT&T's strategy increasingly emphasizes the relationship between home internet and wireless connectivity.
A customer who can obtain both services from the same provider may see advantages in convenience, account management and available service combinations.
For AT&T, offering fiber and wireless together can create opportunities to deepen customer relationships and improve retention.
The combination also gives sales organizations more ways to address a customer's overall connectivity needs.
What the Buyers Could Do With AT&T Mexico
Grupo Televisa and Fintech Holdings are acquiring an established wireless operation rather than building a network and customer base from the beginning.
That creates opportunities to explore operating efficiencies, distribution strategies and potential service combinations.
However, the buyers will still face challenges involving competition, network investment and profitability.
The transaction's longer-term impact on the Mexican wireless market will depend on regulatory approval, closing and the strategies implemented afterward.
What This Means for Authorized Dealers
For Authorized Dealers, AT&T's shift toward U.S. fiber and wireless expansion creates several practical considerations.
As the company's network grows, previously unserviceable locations may become eligible for fiber service.
Dealers can revisit past customer inquiries, verify current availability and identify opportunities to serve customers looking for wireless, home internet or both.
The key is to stay informed about changes in the service footprint rather than relying on outdated assumptions about where AT&T Fiber is available.
