Yes, you can generally count on a stable 4G signal for most of your ferry journey to Culebra or Vieques. While the ride can be around 60-90 minutes, the ferry typically stays within reasonable proximity to the coast, maintaining connectivity. You should be able to browse, check updates, or even stream light content. There might be brief moments where the signal dips in the middle of deeper channels, but overall, you'll remain connected to plan your island exploration or share updates from the sea.
