When visiting Harrison's Cave in Barbados, NorthESIM provides reliable signal at the visitor center and immediate surrounding areas. However, as you venture deeper into the cave's underground passages during the tram tour, expect a gradual loss of signal. The natural geological formations can impede cellular transmission. Our service aims for optimal connectivity, but some unique environments pose challenges.
