When Ruby first saw the goons she tried to call but she couldn't. I was quite surprised that Ruby's scroll (which is presumably hooked into Remnant's miltiary communications network as she's a trainee Huntress) couldn't get any service. I skirt around that by presuming that the White Fang base had a comms jammer of some kind.
