Caribbean island connectivity depends on island size and development level. FLOW's coverage in Cayman Islands serves populated areas and tourist resorts. Beach areas typically have usable signal. Interior mountains and undeveloped coastline may not. A travel eSIM works anywhere FLOW's towers reach.
Cruise passengers visiting Cayman Islands on port days benefit from a travel eSIM. Shore excursion connectivity depends on your proximity to FLOW's towers. Urban port areas have strong signal. Remote beaches and nature excursions further from town may lose coverage. The eSIM activates on arrival and pauses when you return to the ship.
