Do cell phones work in tornado and storm shelters?
In most cases, cell phones will work. We advise you to check out your cell signal prior to an emergency. If your cell phone doesn’t have a signal, you may want to invest in our Guard Alert system which is an option that provides electricity, phone, TV, a ventilating fan and two emergency siren capabilities. The fan and siren are backed up with a 12 volt battery with a trickle charger that keeps the battery fully charged at all times. Typical functional battery time is 22 hours for the siren and fan after power is lost.
