SMS has several advantages. It is more discreet than a telephonic conversation, making it the ideal form for communicating when you don't want to be disturbed. SMS is less time-consuming in comparison to make a phone call or send an e-mail. Unlike email and instant messenger, SMS doesn't require you to be at your computer. SMS is a store-and-forward service, meaning that when you send a text message, the message does not go directly to the client's cell phone. The advantage of this method is that the client's cell phone doesn't have to be active or in range for you to send a message. The message is stored in the SMSC (for days if necessary) until the client turns his cell phone on or moves into range, at which point the message is delivered. SMS is considered to be a spam free mode of communication as compared to email. [color=#000099][/color]
