Bi-Directional (2-way) SMS



A messaging system for sending and receiving text messages that allow commercial users to reply to text messages. For instance, typically bulk SMS is sent out to users, and the user is expected to click a link, call a number, or interact with the information some way. However, nothing prevents the user from replying to the SMS, and most systems do not allow continuous communication or a ‘conversation’ to take place.
