SMS Text Pager - GSM

Global System for Mobile communications (GSM) was originally developed as the European communication standard for digital mobile and cellular service. Currently, GSM is used in more than 160 countries and is widely considered one of the world's main digital wireless standards.

GSM uses narrowband Time Division Multiple Access (TDMA), allowing you to make eight simultaneous calls on the same radio frequency. It is used on the 900 MHz and 1800 MHz frequencies in Europe, Asia, and Australia, and the MHz 1900 frequency in North America and Latin America. It is widely used to take advantage of GSM and SMS mobile communications.

GSM can send a maximum of 5,049 characters per message. It uses direct port access to communicate with a model, and allows you to pause the dialing sequence to select an outside phone line, and supports ipMonitor alert tokens. Additionally, GSM supports full control over your modem settings, including COM port, baud rate, data bits, parity, init string, and dial string, as well as forcing the modem to behave as a low-speed modem.
