Grupo Televisa and Fintech Holdings announced the purchase of AT&T Mexico for USD 2 billion. It is the biggest move in the Mexican mobile market in years, and it raises a question for any company that sends SMS: does anything change for the delivery of its OTPs, alerts and campaigns? The short answer is no, not today. Here is what we know and what is worth watching.
What was announced
On October 13, 2026, Grupo Televisa reported that a consortium owned in equal parts with Fintech Holdings will acquire 100% of AT&T Mexico. These are the key facts:
- Price: USD 2 billion, funded with available cash and debt.
- Size: AT&T Mexico is the country’s second-largest mobile operator, with about 24.7 million subscribers at the end of 2025.
- 2025 results: revenue of MXN 85.4 billion and operating income of MXN 1.4 billion.
- Timeline: closing is expected in the first quarter of 2027, subject to regulatory approvals.
- In the meantime: AT&T Mexico keeps operating as usual. The announcement does not automatically change plans, services or the brand.
Why it matters for the telecom market
The deal combines Televisa’s fixed infrastructure and services with one of the country’s two large mobile networks. That enables converged bundles of internet, phone and TV, and aims to compete more directly with the market leader. For AT&T, the sale lets it focus its investment on the United States, especially fiber and 5G.
Analysts agree that the new owner will need to keep investing in the mobile network, particularly in 5G, to improve profitability. A network with more investment usually means better coverage and service quality for end users, who are also the recipients of your messages.
What changes (and what doesn’t) for companies that send SMS
For a company sending transactional SMS, OTP codes or campaigns, the news requires no immediate change:
- Numbers do not change. AT&T users keep their numbers and keep receiving SMS as before.
- Delivery stays the same. Until closing, and probably for some time after, the network runs under the same structure.
- Your contact lists remain valid. There is no need to clean or segment users of any specific operator because of this deal.
What is worth doing is watching your delivery reports more closely over the coming months. Network and systems integrations between companies usually happen in stages, and any technical adjustment shows up first in the delivery statuses (DLR) of your messages. If your reports show a change concentrated in one group of numbers, that is a signal to review it early. To understand the most common reasons a message is not delivered, see why an SMS is not delivered.
At Grupo Tecnophone we check every number against Mexico’s National Numbering Plan to know whether it is fixed or mobile before sending, and we provide real-time delivery reports per message. That way, any market movement shows up in your metrics from day one. This year brings another factor to keep in mind: Mexico’s CURP phone registration, which suspends unregistered lines every two weeks.
