Short answer: 4S eSIM is designed for mobile networks on land. Cruise coverage depends on whether your phone can connect to a supported terrestrial network near port or shore.
Important
- Ship satellite or maritime networks may not be included.
- Coverage at sea is not guaranteed.
- Check the destination or regional coverage before purchasing.
