This is a great question for cruise lovers! Your SouthESIM will work perfectly when your ship docks at a port and you're on land, connecting to local networks like Claro in Cartagena or DTAC in Phuket. However, while your ship is sailing on the open sea, your eSIM won't function, as this requires a satellite connection which is different from terrestrial mobile networks. So, enjoy connectivity on shore, but plan for offline time or ship Wi-Fi when cruising between destinations.
