Hi Szymon
We provide different build option of the Conduit Gateway,
some have an internal cellular modem capable of PPP for internet access
others do not have an internal cellular modem and only have an Ethernet
interface for access to the internet. If you provide the serial number off
the bottom of your unit, I can verify for you. Otherwise you can also tell
by the model number (on the bottom) and referencing the build options
listed on our website. http://www.multitech.com/brands/multiconnect-conduit
