During the ferry journey to Culebra or Vieques, CoreESIM users can generally expect stable 4G/LTE connectivity for a significant portion of the trip. Given the ferry's proximity to the coast for much of the 60-90 minute duration, network towers maintain line of sight. While there might be brief periods of signal degradation or loss in the deepest parts of the channel, overall connectivity for browsing and communication remains largely uninterrupted.
