A public telephone is a phone that is available for use by the general public, typically found in places like streets, airports, and train stations. These phones allow individuals to make calls without needing a personal phone. Users usually pay for calls using coins, prepaid cards, or credit cards. Public telephones were once common, but their usage has declined with the rise of mobile phones. They are still important in areas with limited mobile coverage or for people who do not own a mobile phone. Many public telephones are equipped with features for accessibility, ensuring that everyone can use them.
