Hi everybody

Could you advise if sky italia prepaid card can be viewed
in Dreambox, I heard about Oscam + Cccam is doing the job.
We are seamans, and have internet only in ports 3G,
at sea we wont to use sky card, have also original receiver
from sky It, but this is pre programmed and not all chanels available.
missing TNT, STS int. ...
So decided to buy dreambox to have all the channels along with Sky, but don't know how to configure Oscam.
Any help is highly appreciated.
