Is dealing as an agent for Mobinil considered a sin, knowing the owner's stances against the hijab and his ownership of a satellite pornography channel?

What the questioner mentioned about the actions and statements of the person in question is a great abomination and a grave danger if it combines corrupt perception and behavior, or belief and action. Nevertheless, it does not prevent the questioner from being an agent for the aforementioned company in mobile phone lines, because mobile phone services are permissible according to Islamic law. This is supported by the fact that the Messenger of Allah, peace and blessings be upon him, used to deal with Jews in permissible matters. The important thing is that the agency contract be for a permissible benefit.
