SMS, otherwise known as text messaging, mobile messaging, or alphanumeric paging, is a digital cellular network feature. It lets you send short text and numeric messages to and from digital cell phones, cell phones and e-mail addresses, as well as cell phones and public SMS messaging gateways on the Internet.
SMS is convenient and cost effective for a number of reasons. When you compare it with the cost of airtime for voice calls or wireless Web access, SMS is a real bargain. Messages can be received while making voice calls, and there are no busy signals to contend with. Plus, if you should you find yourself in a situation where talking on a cell phone is inappropriate, SMS is silent and discreet. Messages generated by SMS are immediately delivered directly to your phone. There is no need to call an access number, as is the case with voice-mail. Also, most carriers offer SMS alerts (information packets, such as stock quotes, sports scores, and news) that can be delivered to your phone at regularly scheduled intervals. |
