Internet plans on board are very expensive and coverage can be spotty. Look into eSIM packages like the one from Red Bull MOBILE and avoid expensive charges.

Let’s talk about roaming charges on your ship. Cruise ships offer internet packages, some starting at $20/day and on some cruise lines you must purchase the package for the full length of your cruise. If you want a one-time 24-hour internet pass, it will be even more expensive. There are different plan options, such as video calls and social media only, or full packages to include streaming movies and music. Each cruise ship company has their own plans and packages, check ahead of time to compare options. 

Great news! The eSIM from Red Bull MOBILE is available on cruise ships and ferries with the Telenor Maritime package. Please note, this package will only work on cruise ships and ferries. To purchase a land package please select the destination where you travel to.

Purchase an eSIM from Red Bull MOBILE Data and never worry about running out of data on your cruise again! 

So, how does it work to get data on your cruise ship and avoid roaming charges?

It works with an eSIM from Red Bull MOBILE for land packages and Telenor Maritime for cruise ships and ferries.

All you have to do is download the app, register, search for – or scroll down to your destination or the Telenor Maritime option, and purchase your package. Please note, the Telenor Maritime package will work on cruise ships and ferries only! To purchase a land package please select the destination where you travel to.
