Good news! With your SouthESIM, you should have a reliable 4G signal for most of your ferry journey to beautiful Culebra or Vieques. The ferries generally hug the coastline, which helps maintain connectivity. While there might be a brief moment or two where the signal dips as you cross deeper channels, you'll largely be able to browse, check messages, or even stream some tunes during the 60-90 minute ride. It's a great way to stay connected and plan your island activities even before you arrive!
