A chatline phone is a type of telephone service that allows users to call in and speak with other individuals who are also using the same service. The main purpose of these calls is usually to engage in conversation, flirt or find companionship. Chatlines typically operate on a pay-per-call basis, where users have to dial an access number and then enter their credit card information to connect with others. Once connected, callers can listen to voice greetings from other members of the service and then engage in live chat or phone sex if desired. Chatline phones are popular among people who want to maintain their privacy while still being able to meet new people or have casual conversations.
