Definitely. Telstra in Australia recently made all their (15000) payphones free and the CEO specifically called out bushfires and cyclones (hurricanes) as events that have brought the mobile network down:
About 11m calls were made across Telstra pay phones in the past year, including 230,000 calls to critical services such as triple zero and Lifeline.
The Telstra chief executive, Andrew Penn, said pay phones were a vital lifeline, particularly for the homeless and people escaping an unsafe situation.
“I have been moved seeing firsthand queues of people waiting in line to use a payphone to tell their family and friends they’re safe after a bushfire, a cyclone or some other natural disaster has taken the mobile network down,” he said.[1]
I believe the existence/number of payphones is mandated by the federal government.
