A phone call is a conversation between two or more people using a telephone. It allows individuals to communicate in real-time, sharing information, ideas, or feelings. Phone calls can be made using landline phones or mobile devices, and they can connect people across short or long distances. During a phone call, participants can hear each other's voices, which helps convey tone and emotion. Modern technology also allows for video calls, where users can see each other while talking. Phone calls are commonly used for personal conversations, business discussions, and customer service interactions.
