Fall in prepaid
Mandatory cell phone registration already impacts operators. AT&T Mexico reported a loss of one million prepaid users during the second quarter of 2026. At the end of June, the company added 15 million 829 thousand subscribers in that segment, according to its financial results.
In contrast, postpaid customers grew by 369 thousand, an increase of 20.7%, to reach 7 million 457 users. The difference is due to the government requirement to register all lines in the cell phone registry.
The original deadline expired at the end of June, but only 43% of the lines had been registered. The federal government extended the date. The suspension of service will begin on August 15 and will be staggered until December 31, depending on the last digit of the number.
The consulting firm The Competitive Intelligence Unit (CIU) pointed out that the contraction of prepaid lines is directly due to this obligation.
Financial results
Despite the drop in prepaid, AT&T Mexico’s total revenue reached $1,224 million in the second quarter, an increase of 16.1% compared to the same period in 2025. The company attributed the growth mainly to the favorable exchange rate.
EBITDA amounted to 227 million dollars, an increase of 12.9%. In contrast, operating income fell by 8 million, reaching $38 million.
The general director of AT&T Mexico, Mónica Aspe, stated:
“The results for the second quarter of 2026 reflect the discipline with which we execute our strategy: strengthening the network, taking care of the relationship with our customers and maintaining focus on initiatives that drive profitable growth.”
Regarding the registration, Aspe added: “Looking to the second half of the year, we will continue to focus on successfully completing the process of linking mobile lines.”
The company also highlighted its deployment of 5G in stadiums and Fan Fest areas during the world soccer tournament, an investment that considers lasting infrastructure beyond the event.
