Overview
- Users across Mexico reported interruptions to Telcel mobile data, voice, the Mi Telcel app and online recargas on Monday, August 17, 2026.
- Monitoring site Downdetector recorded several spikes that topped 400–500 user reports during the morning and midday, though those counts are not an official measure of total impact.
- Telcel acknowledged problems on its official X account and showed a maintenance message on the Mi Telcel portal but has not given a technical cause or a firm restoration time.
- The disruption coincided with the CRT deadline for mandatory line registration and some users lost service because their lines were suspended, yet many customers with active, registered lines also reported problems.
- Customers are affected when they cannot check bills, make payments or buy airtime, and the episode could raise demand for clearer CRT guidance and faster fixes from Telcel as suspended users can still complete registration to restore service.
