SMS messaging is a feature of GSM-based cellular telephone services. SMS-enabled controllers can use SMS messaging to send and receive data to and from a cell phone. Both fixed text and variable data can be communicated. This feature can be used to transmit data and for remote diagnostics.
SMS messaging is featured in several sample applications; these may be found by selecting Sample U90 Projects from the Help Menu.
In order to use this feature, you must connect an SMS-enabled controller to a GSM modem, which is sometimes called a cellular IP modem. Other modems do not support connection to a cellular network.
SMS messaging is subject to all of the limitations of normal cellular network use, as for example network availability.
Note that SMS messages are limited to the English character set.
