A landline is a traditional telephone that connects calls through physical wires. These wires run from your home to a central office, allowing you to make and receive calls. Unlike mobile phones, which use radio signals, landlines provide a stable connection, making them reliable for clear conversations. Many people still use landlines for their homes, especially for emergency services like 911 in the United States. While mobile phones have become more popular, landlines can be beneficial for families, as they often come with features like call waiting and voicemail, ensuring you never miss an important call.
