As Hurricane Dorian approaches Florida, major wireless networks are announcing how they'll work to make sure customers can stay connected. One of them is even touting its drones as a way to keep communication flowing.

AT&T

The company says on its website it will waive overage charges on mobile services, giving unlimited talk, text and data for AT&T wireless and AT&T prepaid customers in affected areas in Florida from Sept. 2 to Sept. 8.

AT&T also says its fleet of repair teams have several assets at their disposal including dozens of mobile cell towers. It also says it has what it calls a Cell On Wings (COW) which is an acronym describing a drone. This video from AT&T explains how COWs work. They are tethered to a power source below and can serve as a mobile cell tower so customers and first responders can stay connected.
