A landline is well-known to everyone as a traditional phone system that uses physical wires or cables to transmit voice calls and data over a telecommunications network. The phones are typically connected to a wall jack or phone socket in the building. A landline can provide a stable and reliable connection with few dropped calls or connection issues. It works even in areas where mobile phone service is limited or unavailable. Some landline phone plans may offer additional features such as call waiting, voicemail, and caller ID.
