I’ve had multiple power outages this year and neither my iPhone 11 Pro Max or my wife’s iPhone X will work during the outage. My neighbors with AT&T all have useable cell phones during this time. The Verizon fix was to send me a signal booster that will also be off during a power outage. I have to drive to the next town for my phone to work. Anyone know a fix to have a working cell phone when I need it most?
