Payphones were once a common sight on street corners, but now they've become a rare commodity. These days, you might hear them called different names, depending on where you are in the world. In Australia, they're known as a public phone or a Telstra phone, while in the UK they're called a public telephone or a red telephone box. In Canada, they're sometimes referred to as a phone booth or a coin phone, while in New Zealand, it's known as a public call phone. The term "pay phone" has become somewhat outdated due to the rise of mobile phones and the widespread availability of inexpensive phone plans.
