Ship-specific guides to what works at sea, what works in each port, and what it costs. Every price links to its source and carries the date we checked it. We compile published information and don't claim to have tested every plan.

How we research

• We check each port's country, because that decides which eSIM works.
• We keep ship Wi-Fi and maritime cellular (carrier cruise passes, cruise eSIMs) apart. They're different services with different bills.
• Every price links to its source and shows the date we checked it. Free options (airplane mode, plans you already have) are always included.
