Why Your Cell Phone Goes Silent in a Long Blackout

Your phone can be fully charged and still show two small words: No Service. In a long blackout, your phone doesn't go quiet because of its own battery. It goes quiet because everything it depends on runs out first. In the 2019 California shutoffs, 874 cell towers went offline in a single day. What you'll learn: - Why many home phones stop working the moment the power goes out - How cold drains your phone, and simple ways to make the charge last - Why calls fail when everyone dials at once, and why a text often gets through - What keeps a cell tower running in an outage, and why nobody can promise how long - A simple family plan for when nobody can reach anybody - Why a radio still works when everything else goes silent, and the 30-second check that makes sure yours does Safety note: Never run a car, generator or any fuel-burning engine inside a garage, even with the door open. Charge your phone from the car only with the car parked outside. Keep a carbon monoxide alarm with a working battery. If you rely on medical equipment that needs power, make a plan with your doctor and your power company ahead of time.
