The SIM900 is an ultra-compact and reliable quad-band GSM/GPRS module in an SMT package. Built around a powerful single-chip processor with an ARM926EJ-S core, it delivers voice, SMS, data, and fax capabilities in a tiny 24 × 24 × 3 mm form factor weighing just 3.4 g.

Operating across the 850/900/1800/1900 MHz bands, the SIM900 is ideal for M2M applications where space and power efficiency are critical. It supports embedded TCP/UDP, FTP/HTTP, MMS, and multiplexing protocols, and is controlled via standard AT commands.
