A weather alert woke our whole house, but one phone stayed silent

A severe-weather alert sounded on three phones in our house just after midnight. My partner's phone made no sound. It was charged, connected, and sitting on the nightstand.

The alert passed without damage in our area, but the silence bothered us more than the noise. We had assumed every phone would behave the same because they use the same carrier and were in the same room.

When we looked the next morning, the phones did not have identical settings. One had a sleep focus enabled. Another had government-alert categories arranged differently. My partner's phone had recently been replaced and restored from a backup, so we did not know which settings had transferred. We also could not tell whether the alert had been received silently, suppressed, or never delivered.

This is not a feature I want to test by waiting for the next dangerous night. We can compare the official alert settings on each device, check notification history where available, install or verify a trusted local weather source, and make a household plan that does not depend on one handset. A weather radio or another independent channel may be appropriate for our situation.

I do not want to promise that any phone setting guarantees delivery. Networks, location, device state, and the type of alert can matter. I do want to remove preventable differences and understand which quiet modes can override which notifications on our actual devices.

How would you audit a household's emergency-alert setup without creating false confidence? What redundant channel is practical for a family that already has several phones but just learned that “several” is not the same as “reliable”?
