This messaging service is very simple and built into the phone.The phone service provider (Verizon, Sprint, ATT etc.) delivers the message for the user through the cellular network as opposed to the Internet. It is entirely possible, and highly likely, that users will utilize both the phone carrier’s network to send SMS messages, while also using a messaging app to communicate over the phone's Internet (data) connection.
Other examples are “AIM Chat” and “Google Hangout.” There are, however, many other chat room web sites that focus on chatting exclusively and are not tied with major search engine web sites.These communications appear instantaneously on the recipient's computer once the sender presses “enter” or selects “send.” It is important to make a distinction between the various types of messaging platforms and possibilities. Messaging programs can be found for both computers and smartphones.Computers require a small program to be downloaded and installed whereas a smartphone user can easily install an app from the manufacturer’s app store.There are several available with some of the more popular ones being Whats App, Facebook Messenger, QQ Mobile, We Chat, Viber, and even Skype.The old days it was Yahoo Messenger, Windows Live Messenger, and AIM (America Online IM).
