When visiting the incredible Harrison's Cave in Barbados, you'll find SouthESIM provides a good signal at the visitor center and entrance areas, perfect for checking in or downloading information. However, as you delve deep underground on the tram tour, surrounded by the cave's natural formations, expect to lose connection. It's a great chance to unplug and fully immerse yourself in the geological wonder! You'll reconnect once you're back above ground.
