Earthquake alert system fails on some cell phones during the September 19th drill: this is what users are reporting

On September 19, Mexico conducted its Second National Drill to commemorate the historic earthquakes of 1985 and 2017. The exercise, which took place at 12:00 p.m. Central Time, involved the activation of seismic alerts across public loudspeakers and mobile devices to practice emergency response protocols nationwide.

While the drill reached millions of participants, reports emerged from users indicating that the seismic alert failed to trigger on some mobile devices. The exercise remains a key component of national disaster prevention efforts intended to prepare the population for potential seismic activity.
