Can I use my mobile data on a cruise ship?

Do cell phones work on cruise ships? It's a common question with varying answers. Guests are free to utilize their cellular data or connect to our onboard Wi-Fi on any ship. But, please be aware that cellular data used on the ship or in certain ports of call will result in charges from your cell phone provider.



You can technically use your mobile data on a cruise ship, but doing so without a specific plan is one of the most expensive travel mistakes you can make. When a ship is at sea, it connects to "Cellular at Sea" via a satellite link, which is not covered by standard international roaming plans. Rates can reach $10 to $15 per megabyte, potentially leading to a bill for thousands of dollars after just a few minutes of browsing. To stay connected safely, you should either purchase the ship's official Wi-Fi package (which uses Starlink on many modern lines in 2026 for better speed) or check if your carrier offers a specific "Cruise Plan." Even with a plan, data is often throttled. The best practice is to keep your phone in Airplane Mode with Wi-Fi enabled while at sea and only use your cellular data once you are docked at a port where your standard international roaming or a local eSIM applies.

Data use onboard a cruise ship is ridiculously expensive, especially because it tends to add up quickly. Always remember to put your phone in airplane mode or turn off data roaming before you head out to sea and don't want to be smacked with a hefty bill upon returning home. Even in port, the rates get pretty high.

But, please be aware that cellular data used on the ship or in certain ports of call will result in charges from your cell phone provider.

If you're not able to wait for ports of call (or don't have international data on your phone), it might be worthwhile to pay for a Wi-Fi package. Although prices have decreased over the years, it can still be pretty costly to purchase Wi-Fi for your cruise.

At sea, mainstream cruise lines usually do not include Wi-Fi in their cruise fares, but premium and luxury lines almost always do. Cruise lines that include free Wi-Fi for all passengers are luxury lines like Seabourn, Silversea and Regent Seven Seas Cruises, along with upscale cruise lines Oceania Cruises and Viking.

Better to keep cellular service off. Airplane mode will switch off your phone's transmitters for cell signal (calls and text messages) and data (browsing the web, using apps) ensuring you will not be privy to unwanted charges. But don't worry: Your smartphone won't be completely useless for the trip.

Internet on cruise ships is provided primarily by satellites, though some cruise ships have technology onboard that allows them to switch to land-based signal towers when sailing within a certain distance from land.

It's possible to send and receive text messages at sea on a cellular signal, as long as you have a signal through your ship's roaming network. (Just make sure you turn on data roaming in your settings.)

To avoid unwanted charges, your safest bet onboard your cruise ship is to switch to airplane mode, reactivate your wireless feature and log in to the ship's Wi-Fi network. (Note: Switching to airplane mode will turn off wireless until you manually reactivate it.)

Food and drinking are usually complimentary on the cruises. You are also allowed to bring your own snack on the cruise so that you can have what you love. A certain time is fixed for every meal - breakfast, lunch, and dinner. You can either have it with everybody in the dining room or bring it to your room.

For most people, the best piece of advice is to put your phone on airplane mode before your ship sets sail out of port. This prevents your cell from trying to stay connected, thereby eliminating roaming charges. Of course, this also stops you from making and receiving calls and text messages.
