Does HotelESIM function on a cruise ship while we are sailing at sea?

It's important to note that HotelESIM, like most standard mobile eSIMs, relies on land-based cellular towers for connectivity. Therefore, while your cruise ship is in the open ocean, far from shore, your eSIM will not provide service. However, HotelESIM will activate and work perfectly as soon as your ship approaches and docks at a port, such as in Nassau or Freeport. It’s an excellent way to stay connected when exploring ports of call without relying on expensive shipboard Wi-Fi packages.
