No, but here’s a possible explanation:
One of the women is attacked y an animal, or falls off a cliff, and is either dead or unconscious. The other woman’s phone battery dies. She tries to use her dead/unconscious friend’s phone to call for help. Unfortunately, she doesn’t know her friend’s pin (do you know any of your friend’s phone PIN codes?). Eventually, exposure or another animal took the second woman out.
either that or Julio wanted to watch a novella on Youtube
