Cultural Tip
Public phones are far less common in many big cities today, but they still exist in train stations, bus terminals, and small towns across Spain and Latin America. In Spain you’ll often find them inside *kioscos* (newsstands) that also sell cigarettes and snacks. They usually require coins (often €0.50 or $0.25) and may have a short‑time limit per call. When traveling, it’s handy to keep a few small change pieces just in case you need to use one.
