Yes, your CoreESIM will provide immediate connectivity upon docking in Greenlandic ports. Unlike expensive and often slow satellite Wi-Fi on cruise ships, a CoreESIM leverages local terrestrial networks. As your ship enters harbors like Ilulissat, Nuuk, or Qaqortoq, your device will seamlessly connect to the local 4G network, providing reliable data for communication and navigation during your shore excursion.
