How to Use Cruise Ship Wi-Fi to Stay Connected at Sea
Imagine coming home from a relaxing cruise and opening your cell phone bill only to discover that you owe hundreds of dollars more than usual.
For many cruisers, that is a very real concern.
The good news is that you have several ways to stay connected while cruising. In this guide, I’m sharing how I personally use cruise ship Wi-Fi to text, email, make phone calls and video call while I’m at sea, along with some other options you may want to investigate.

First: Understand the Difference Between Ship Wi-Fi and Cellular at Sea
There are two very different ways your phone can connect while you’re cruising.
Ship Wi-Fi connects your phone, tablet or computer to the internet through the cruise ship’s Wi-Fi network.
Cellular at Sea is different. The ship has its own cellular network, which allows compatible phones to connect to cellular service while the ship is at sea. That cellular usage is handled through your wireless carrier and is billed according to your carrier’s applicable roaming terms or cruise plan.
That’s why I make a very deliberate choice about how I connect when I’m cruising.
My goal: use the ship’s Wi-Fi instead of accidentally using cellular service at sea.
My Number-One Cruise Phone Rule: Airplane Mode
When I board a cruise, one of the first things I do is put my cellular devices into Airplane Mode.
Then, if I have purchased a Wi-Fi package, I turn Wi-Fi back on and connect to the ship’s Wi-Fi network.
Why?
Because if your phone is allowed to connect to the ship’s cellular network, your usage can be billed by your wireless carrier under its cruise or roaming terms. Cellular at Sea explains that the ship’s onboard cellular network connects to the carrier through satellite, with the usage ultimately billed through your home carrier.
Putting your phone in Airplane Mode is my preferred way of avoiding accidental cellular-at-sea usage when I intend to use Wi-Fi instead.
And don’t forget about other cellular-enabled devices. If you have a cellular Apple Watch, cellular iPad or another device with its own cellular connection, check those devices as well.
My routine is simple:
Airplane Mode ON → Wi-Fi ON → connect to the ship’s Wi-Fi.
What Can You Do Without Purchasing a Wi-Fi Package?
Cruise lines structure their connectivity differently, so I don’t want to tell you that every cruise line offers exactly the same packages.
However, many cruise lines allow guests to connect to the ship’s network to use the cruise line’s app without purchasing a full internet package.
The exact features vary by cruise line and sailing.
Your cruise line’s app may allow you to:
- View your daily schedule
- Check dining and entertainment information
- Make reservations
- View your onboard account
- Access your cruise information
- Communicate with other guests through an onboard messaging feature on some lines
Some cruise lines charge for certain onboard communication features, while others include them.
Check the specific cruise line and ship you’re sailing before you assume a particular feature is free.
Cruise Wi-Fi: Think of It as Different Levels of Connectivity
I’m going to simplify cruise internet into three general levels because cruise lines use different names, packages and pricing structures.
The package available to you can vary by cruise line, ship and sailing.
Level 1: No Full Internet Package
This is the option for someone who primarily needs the cruise line’s app and onboard information.
You won’t necessarily have general internet access just because you can connect to the ship’s Wi-Fi network.
If your goal is to communicate with people back home, you’ll generally need an internet package or another form of connectivity.
Level 2: Basic Internet Connectivity
The next level is a basic internet package.
Depending on the cruise line and package, this can allow you to do things such as:
- Check email
- Browse websites
- Send internet-based messages
- Use messaging apps
- Use social media
- Stay connected with family and friends
This is the level I often use when I don’t need to do anything particularly demanding.
For example, when I’m cruising, I have used:
iMessage to communicate with other iPhone users.
Facebook Messenger to communicate with people who use Facebook.
Instagram messaging with family members who use Instagram.
And there are other messaging services, such as WhatsApp, that can work over an internet connection.
The important thing to understand is that these are internet-based communications, not cellular-at-sea calls or texts.
What About iMessage?
You may hear people talk about using iMessage on a cruise without purchasing an internet package.
I wouldn’t count on that.
Cruise line connectivity policies can change, and what works on one ship or sailing may not work on another.
If staying connected is important to you, I recommend planning around the connectivity option that your cruise line currently says is supported rather than relying on an internet “hack.”
Level 3: Higher-Speed or Premium Wi-Fi
If you want to do more demanding things online, a higher-level Wi-Fi package may be available.
Depending on the cruise line and package, this may support things such as:
- Video calls
- Streaming
- YouTube
- Netflix
- Social media video
- Larger uploads
- More intensive web use
For me, this is the type of package I choose when I need to do more than simply check email and send messages.
I work while I travel, so being able to communicate with clients and vendors can be important.
I’ve also used cruise Wi-Fi for video calls with family.
But there’s an important caveat:
A higher Wi-Fi package doesn’t guarantee perfect connectivity.
Your connection can still vary based on the ship, location, satellite connectivity, weather and other factors.
Cruise lines have increasingly adopted Starlink technology for onboard internet, which has improved connectivity on many ships, but cruise Wi-Fi is still not identical to the internet connection you have at home.
How I Make Phone Calls Using Cruise Ship Wi-Fi
This is probably the part of my setup that gets the most questions.
Sometimes I need to make an actual phone call—not a Facebook Messenger call or video call.
That’s where Wi-Fi Calling comes into play.
Wi-Fi Calling allows a compatible phone and cellular plan to place calls over a Wi-Fi connection rather than using the ship’s cellular network.
That distinction is important.
Wi-Fi Calling ≠ Cellular at Sea.
When I’m using Wi-Fi Calling through the ship’s Wi-Fi, I’m not intentionally connecting to the ship’s cellular network to make the call.
Set Up Wi-Fi Calling Before Your Cruise
If you want to use Wi-Fi Calling while traveling, I recommend setting it up and testing it before you leave home.
Your carrier’s requirements can vary, so don’t wait until you’re in the middle of the ocean to figure out whether your particular plan supports it.
In my case, I use Verizon.
I enabled Wi-Fi Calling while I was still home and then contacted Verizon to confirm that the setup and charges for my particular plan were what I expected.
That’s what I recommend doing with your own carrier.
Don’t assume that because my Verizon plan works a certain way, your plan will work exactly the same way.
My Setup While I’m at Sea
When I’m using ship Wi-Fi, my basic routine is:
1. Put my phone in Airplane Mode.
2. Turn Wi-Fi back on.
3. Connect to the ship’s Wi-Fi.
4. Use internet-based messaging and apps over Wi-Fi.
5. Use Wi-Fi Calling when I need to make a regular phone call and my carrier/plan supports it.
This allows me to stay connected without intentionally using the ship’s cellular network.
Are Wi-Fi Calls Free?
This is where I want to be very careful because your carrier and your particular plan matter.
For my own Verizon plan, I confirmed with Verizon how Wi-Fi Calling works for calls to U.S. numbers.
Verizon’s current information states that its Wi-Fi Calling service can be used over a Wi-Fi connection, while calls to numbers outside the U.S. can be subject to international calling charges depending on the applicable plan.
So don’t simply assume that a Wi-Fi call is free because it is using Wi-Fi.
Check with your carrier before you cruise.
In particular, ask:
- Does my plan support Wi-Fi Calling?
- Are calls to U.S. numbers included?
- What happens if I call an international number?
- Can I receive calls over Wi-Fi?
- Are there any restrictions while I’m outside the U.S.?
- Does my carrier have a cruise-specific cellular plan?
That five-minute conversation could save you from an unpleasant surprise later.
What About Cruise Cellular Plans?
Using the ship’s Wi-Fi isn’t your only option.
Wireless carriers offer cruise-specific cellular options, and the offerings can change.
For example, Verizon currently offers Cruise Daily Pass for $20 per line per 24-hour session on participating cruise lines. Verizon says the plan includes unlimited talk to the U.S. and unlimited text, plus 0.5 GB of high-speed data before data continues at 3G speeds for the remainder of the session.
AT&T also currently offers cruise connectivity through its International Day Pass at $20 per day per device, with the available data and speeds subject to its terms and participating coverage.
These options may make sense for some travelers.
They aren’t what I personally choose for my typical cruise use, because I prefer using the ship’s Wi-Fi for the type of internet activity I need to do.
But that’s a personal choice.
Before choosing a cruise cellular plan, compare the current price, high-speed data allowance, coverage, participating ships and what happens after you use your high-speed data.
Another Option: Cruise eSIMs
Another option you may come across is a travel eSIM that includes cruise coverage.
An eSIM is essentially a digital SIM that can provide another cellular data connection without requiring a physical SIM card.
But there’s an important distinction:
Not every travel eSIM works at sea.
Some are designed only for land-based cellular networks.
If you’re considering an eSIM for a cruise, make sure the plan specifically includes cruise or maritime coverage.
You’ll also need a compatible device, and the phone may need to be unlocked.
For example, Cellular at Sea currently offers Cruise+ eSIM service for compatible unlocked, eSIM-capable devices, with coverage designed to work at sea and on land.
I haven’t personally used these services, so I’m not recommending one over another.
I’m simply pointing out that they’re another option worth researching.
Which Cruise Connectivity Option Is Right for You?
There isn’t one answer for every cruiser.
Think about what you actually need to do.
If you only need the cruise app:
You may not need a full internet package.
If you mainly want to send messages and check email:
A basic Wi-Fi package may be enough.
If you want to stream, make video calls or upload content:
A higher-level Wi-Fi package may make more sense.
If you need your regular phone number active at sea:
A cellular-at-sea option from your carrier may be worth investigating.
If you want prepaid data and have a compatible unlocked phone:
A cruise eSIM could be another option.
And remember that you can sometimes combine these approaches depending on your needs.
My Cruise Connectivity Strategy
For me, the decision is pretty simple.
I need to be able to:
- Check email
- Communicate with clients and vendors
- Contact family
- Check on things at home
- Make an occasional phone call
- Video call when necessary
- Use social media
- Upload content when I need to
So I generally prefer having a cruise Wi-Fi package that gives me the connectivity I need.
And when I’m intentionally using Wi-Fi rather than cellular service at sea, my routine is:
Airplane Mode ON.
Wi-Fi ON.
Connect to the ship’s Wi-Fi.
Use internet-based communication and Wi-Fi Calling when appropriate.
It’s the system that has worked well for me.

Before Your Next Cruise, Do These Five Things
Before you sail, I recommend taking a few minutes to prepare.
1. Check your cruise line’s Wi-Fi packages
Don’t assume that the package you had on your last cruise is the same package you’ll have on your next one.
2. Check your wireless carrier
Ask specifically about cruise cellular service, roaming and Wi-Fi Calling.
3. Set up Wi-Fi Calling at home
If you plan to use it, test it before you leave.
4. Check your cellular-enabled devices
Don’t forget about cellular Apple Watches, iPads or other connected devices.
5. Decide what you actually need
Do you need to stream movies?
Make video calls?
Work remotely?
Or do you simply want to send a few messages home?
Knowing your usage before you sail can help you avoid paying for more connectivity than you actually need.
The Bottom Line
Staying connected on a cruise doesn’t have to mean automatically using Cellular at Sea.
For me, cruise ship Wi-Fi is the primary way I stay connected while I’m at sea, and Wi-Fi Calling gives me another way to make regular phone calls when my carrier and plan support it.
But your setup may be different.
Cruise Wi-Fi packages, cellular plans, pricing, coverage and technology change frequently. Before you sail, check the current information for your specific cruise line, ship, itinerary, wireless carrier and phone plan.
A few minutes of preparation before boarding can help you enjoy your cruise without wondering what kind of cell phone bill you’ll find when you get home.
