"We were pleased that carriers had pre-positioned equipment and were in the process deploying cells on wheels (COWs) and cells on light trucks (COLTs) in order to get wireless service up and running in many locations", Pai said in a statement.
"I know we have a lot of people that I have heard are injured", Governor Rick Scott, who plans to visit impacted areas later in the day, told CNN. The video shows collapsed roofing and walls, scattered debris and mangled building materials.
The hurricane damaged hospitals and nursing homes in the Panama City area, and officials worked to evacuate hundreds of patients.
Many residents with destroyed or damaged homes counted themselves lucky to have survived.
Michael killed at least six people - including a man who died when a tree toppled onto his house in Florida and a girl who died when debris fell into a home in Georgia, officials and local media said.
There have been six confirmed storm-related deaths so far - four in Florida's Gadsden County, one in Georgia, and one in North Carolina.
"Our biggest thing is the downed lines and the downed trees", said Apalachicola Mayor Van Johnson. Roofs had been peeled off and carried away. Aluminium siding was shredded to ribbons. Homes were split open by fallen trees. "We thought the windows were going to break at any time", Beu said.

In Panama City, buildings were crushed, tall pine trees were sent flying and a steeple was knocked off a church.
"The ragged but still raging remains of Hurricane Michael have now come to North Carolina", Cooper said.
"For North Carolina, Michael isn't as bad as Florence, but it adds unwelcome insult to injury, so we must be on alert", Gov. Roy Cooper said.
Steve Sweet, who lived in Gretna, Florida, was killed by a falling tree.
Michael also disrupted energy operations in the U.S. Gulf of Mexico as it approached land, cutting crude oil production by more than 40 percent and natural gas output by almost one-third as offshore platforms were evacuated. But it moved fast and intensified quickly, and emergency authorities lamented that many people ignored the warnings.
Michael, the third-most powerful hurricane ever to hit the USA mainland, weakened overnight to a tropical storm and pushed north-east, bringing drenching rains to Georgia and the Carolinas, which are still recovering from Hurricane Florence last month.
The storm's maximum sustained winds have decreased to 50 miles per hour and it was moving to the northeast at 21 miles per hour.
