SIM508/548 module is a Tri-Band/Quad-Band GSM/GPRS-enabled module
that is also equipped with AGPS technology. The compact design of
the SIM508/548 makes it easy to integrate GSM/GPRS & GPS as an
all-in-one solution. You will save significantly both time and cost
for the integration of additional hardware components.
The combination of both technologies can fit almost all the space
requirement in your applications, it allows valuable asset to be
tracked seamlessly at any location and anytime with signal
coverage. General features - Tri-Band GSM 900/1800/1900MHz, or Quad-Band GSM 850/900/1800/1900
