SIMCom presents an ultra compact and reliable wireless module-SIM900. This is a complete Quad-band
GSM/GPRS module in a SMT type and designed with a very powerful single-chip processor integrating
ARM926EJ-S core, allowing you to benefit from small dimensions and cost-effective solutions.

Featuring an industry-standard interface, the SIM900 delivers GSM/GPRS 850/900/1800/1900MHz performance for voice,
SMS, Data, and Fax in a small form factor and with low power consumption. With a tiny configuration of 24mm x 24mm x
3 mm, SIM900 can fit almost all the space requirements in your M2M applications, especially for slim and compact
demands of design.
