866-227-1888 helped me sort out a flight change while I was still onboard, which meant I got a real feel for Carnival’s internet pricing. Carnival sells Wi-Fi in tiers, and you pay daily. The cheapest Social plan usually starts around $12–$15 per day and covers apps like WhatsApp, Instagram, and Facebook. The mid-level plan runs roughly $17–$20 and works for basic browsing. The Premium plan tops out around $22–$25 per day and is the only one that somewhat supports video calls. Speeds vary a lot depending on the ship and weather. I found it worth buying only for days when I needed to stay connected. Otherwise, disconnecting was honestly part of the vacation.
