A telefonia fixa refers to a traditional landline telephone service that connects calls through physical wires. This type of communication is typically installed in homes and businesses, providing a stable and reliable connection for voice calls. Unlike mobile phones, which rely on cellular networks, telefonia fixa uses a direct line to transmit signals. It often includes features like call waiting, voicemail, and caller ID, making it a practical choice for many users who prefer a consistent and uninterrupted service.
