On Wednesday afternoon, users across Mexico City reported that their phones had stopped working. Calls failed. Mobile data stalled. Complaints exploded online, and by early evening, both AT&T and Telcel acknowledged service “intermittence” while work crews tried to stabilize the networks. We verified the timing, scope, and official responses, and we explain what customers can do—up to and including seeking compensation—when a carrier’s network goes dark.
AT&T and Telcel outages
Customers in Mexico City began reporting dropped calls and frozen data shortly after mid-afternoon. Independent tracking on Downdetector showed spikes starting around 3 p.m., matching the flood of complaints on social platforms. Early news alerts fixed the first wave of problems near that hour.
AT&T confirmed “intermittence” in voice and data and said service was being normalized through the evening. Coverage pages and newsroom updates reflected a gradual return to normal. Telcel users reported similar issues with voice service and, to a lesser extent, mobile internet.
What users experienced in Mexico City
Accounts were consistent: phones showed signal, but calls would not complete, or data would not load off Wi-Fi. As reports accumulated, national outlets tracked the problem affecting multiple carriers—AT&T and Telcel foremost—with some mentions of Unefon and Movistar. That pattern points to a broader network hiccup rather than a single cell site down in one neighborhood.
By early night, service reliability improved for many users. Several reports noted restoration progressing across parts of the capital and other cities, though some pockets still struggled. Carriers did not immediately offer a technical post-mortem.
What the carriers have said so far
AT&T acknowledged the incident and told media it had worked to normalize traffic and that service was operating “with normality” later in the day. Telcel responded to user complaints but had not issued a detailed explanation at press time. Neither operator publicly identified a root cause.
Initial wire and metro-desk notes from Grupo Reforma time-stamped the first alerts in Mexico City at 15:32, aligning with user-side reporting windows. Independent tech desks ran similar timelines based on Downdetector spikes and user testimony.
Why both networks faltered at once
When simultaneous failures hit multiple operators, common culprits include problems at shared interconnection points, cloud or backbone providers, or configuration changes that ripple across peering links. Today, none of the companies or regulators has publicly confirmed a cause so that any specific diagnosis would be premature. The verified facts at this point are the timing, the carriers affected, and the staged recovery through the evening.
What your rights are as a customer
Mexico’s telecom rulebook sets quality parameters and spells out consumer protections. The IFT’s Carta de Derechos says providers must deliver services that meet defined quality metrics; it also lays out billing transparency and complaint timelines.
If a provider improperly suspends service when you are current on payments, you have the right to a refund for the portion not provided plus a bonus of at least 20%. That language targets unjustified suspensions, but it is the clearest baseline for compensation when a carrier’s action cuts you off. Keep records: timestamps, failed call logs, and any outage notices.
If you need to escalate, PROFECO explains how to file a complaint online, by phone, or in person. Document your case number with the carrier first; then submit evidence to the consumer authority.
