Will my EastESIM work on a cruise ship at sea in Asia?

EastESIM relies on land-based cellular networks, so it will generally not work when your cruise ship is in the open ocean, far from any coast. At sea, your phone would typically connect to expensive satellite-based ship Wi-Fi or cellular services. However, your EastESIM will become fully active and provide high-speed data as soon as your ship docks at any port in Asia, such as Singapore, Phuket, or Halong Bay. This allows you to explore each destination with local connectivity without relying on expensive ship services.
