for I have understood that the internet has module is used is the v200-19-rs4-x ^ 3
but for communication for gsm module not to use or purchase equipment that I work with this OPLC,, it is clear that I need to work in this region of Colombia where manipulating 3GSM sim card ...
no more waiting for me thankfully dismissal prompt and satisfactory response
