Many travelers assume their international eSIM will continue working throughout a cruise. In reality, once a ship sails away from shore, your phone may connect to the ship's satellite network instead of a land-based mobile network—potentially leading to unexpected roaming charges.
To address this, eSIM provider Saily has introduced dedicated cruise data plans that work on more than 200 cruise ships across several major cruise lines, including Royal Caribbean, Carnival, Norwegian Cruise Line, MSC Cruises, Disney Cruise Line, Virgin Voyages, P&O Cruises, and Cunard.
The plans are designed specifically for onboard connectivity and can be purchased before departure. Pricing starts at around $16.99 for a one-day plan, with larger data packages available for longer sailings.
Before your next cruise, it's also worth checking whether your cruise line offers Wi-Fi packages or if your mobile carrier includes maritime coverage. Comparing your options ahead of time could help you avoid unexpectedly high roaming charges while at sea.
