The Decision, Honestly
Ask three questions. How many sea days (days with no shoreside alternative? Do you need to be reachable, or just want to post later? And what does your own carrier actually cover: check separately whether your plan covers service in the ports you'll visit and whether it offers a maritime or cruise-specific option) an ordinary international day pass may NOT cover the ship's cellular-at-sea network, and a phone left roaming at sea can generate painful charges. Keep cellular data and roaming off at sea unless your carrier confirms coverage.
Wifi ashore can reduce the need for a ship package, though it's worth avoiding sensitive logins on unsecured public networks. Onboard, the cruise line's app on most major lines currently lets guests message each other over the ship's network without buying internet: the answer to "how do we find each other on the ship" for most groups: though a few lines charge a small fee, and package device limits vary. Ship-by-ship internet quality varies enough that it's worth asking us about your specific ship; we hear back from clients on which vessels' internet actually holds up.
Buying pre-cruise is usually cheaper than buying onboard.
Accurate as of September 2026; cruise-line policies change, and your line's own documents govern. When in doubt, ask your line, or ask us, which is free and comes with opinions.
