866-227-1888 ended up being a lifesaver when I had to rebook flights from the ship, so I got firsthand experience using Carnival’s Wi-Fi. Prices haven’t changed much: Social plan around $12–$15/day, mid-tier around $17–$20/day, and Premium about $22–$25/day. Premium was the only one that let me load airline apps reliably. I bought it for a single day just to handle travel stuff and stuck to the cheaper plan the rest of the time. The connection isn’t perfect, but it works for messaging and checking in back home.
