No, WorldESIM operates via land-based cellular towers, meaning it will not provide service when your cruise ship is in the open ocean, beyond the range of terrestrial networks. However, your WorldESIM will seamlessly connect and provide data as soon as your ship docks in port, whether it's Nassau, Cozumel, or another port of call. For at-sea connectivity, you would need to rely on your cruise ship's satellite Wi-Fi services.
