Key Takeaways

• AT&T deactivated 577,000 prepaid lines in Q1 2026.
• Telcel disconnected 483,000 lines, totaling over 1 million combined.
• Regulation requires registration of all mobile numbers by June 2026.
• Operators expect further disconnections as deadline approaches.

Pulse Analysis

Mexico’s telecom regulator, the Comisión Reguladora de Telecomunicaciones (CRT), rolled out a mandatory registration rule in early 2026 to curb the use of anonymous prepaid phones for fraud and illicit activities. The policy obliges carriers to verify each subscriber’s identity and deactivate any line that cannot be linked to a real person. With a hard deadline set for June 2026, operators have been scrambling to cleanse their databases, leading to a wave of disconnections that reflects the law’s aggressive enforcement stance.

The immediate fallout is evident in the numbers: AT&T’s 577,000 deactivations and Telcel’s 483,000 represent a sizable chunk of the prepaid market, which traditionally accounts for roughly 60% of Mexico’s mobile subscriptions. For carriers, each disconnected line translates to lost short‑term revenue and increased churn risk, especially as many users may migrate to competitors or shift to post‑paid plans that already meet registration requirements. To mitigate revenue loss, both firms are investing in rapid re‑verification campaigns, offering incentives for users to update their credentials, and bolstering customer‑service channels to handle the surge in inquiries.

Beyond the immediate financial impact, the registration drive is reshaping the broader ecosystem. Identity‑verification providers and fintech firms stand to gain as carriers outsource compliance solutions, creating a new revenue stream in a market that has long relied on low‑cost, anonymous access. Analysts also predict a gradual erosion of the prepaid dominance, nudging the industry toward a more regulated, data‑rich environment that could attract higher‑margin services such as mobile banking and IoT connectivity. As the June deadline approaches, the pace of disconnections will likely accelerate, making compliance a critical competitive differentiator for Mexico’s telecom players.
