In which moment of the game does Phantom Liberty start?

The new storyline will unlock after you finish the Transmission quest where you encounter Maman Brigitte from Voodoo Boys. Songbird will reach out to you!

If you have already finished the quest or the game — Songbird will contact you shortly after you turn the game on. And if you haven’t played Cyberpunk 2077 at all and want to dive straight into the expansion — you will be able to do that from the main menu!
