Why You Absolutely Need to Turn Off Cellular Data Roaming on a Cruise

As a travel advisor, I’ve seen countless travelers come home from a dream cruise—only to be hit with a nightmare phone bill. If you’re planning your next cruise vacation, do yourself a huge favor: turn off cellular data roaming the moment you step onboard.

Let me explain why this simple step is so important and how it can save you from unexpected (and expensive) charges.

What Is Cellular Data Roaming on a Cruise?

When you’re cruising, especially in international waters, your phone may try to connect to marine satellite networks instead of standard cell towers. These networks aren’t part of your regular mobile plan and can trigger outrageous roaming charges. We’re talking $10 to $25 per megabyte in some cases—yes, megabyte.

Real Talk: I’ve Seen the Bills

I’ve had clients show me post-cruise mobile bills that were hundreds (and sometimes thousands) of dollars higher than expected. All because they didn’t know that their phone was quietly updating apps, checking email, or syncing photos using expensive satellite data while they were relaxing poolside.

Avoid Cruise Roaming Charges: Here’s What I Do

As soon as I board any cruise ship, I do these three things:

1. Turn off cellular data roaming. This is usually found in the “Cellular” or “Mobile Data” section of your phone’s settings.

2. Put my phone on airplane mode. This disables all cellular connections immediately.

3. Enable Wi-Fi (if I plan to use the ship’s Wi-Fi plan).

By keeping my phone in airplane mode with Wi-Fi enabled, I can still stay connected for messaging, emails, or checking in back home—without risking those hefty roaming charges.

What If I Forget to Turn It Off?

Even just a few minutes of background data use while connected to the ship’s satellite signal can lead to charges. Things like app updates, GPS location services, and push notifications can rack up fees quickly without you even opening your phone.

This is why I always recommend getting ahead of it by adjusting your phone settings before you set sail.

Bonus Tip: Download What You Need Before You Sail

I also recommend downloading maps, e-books, entertainment, or translation apps ahead of time—when you’re still on land with Wi-Fi or cell service. It helps you avoid relying on slow or expensive connections at sea.

Final Thoughts: Don’t Let Your Phone Sink Your Budget

Cruising is about relaxing and enjoying the moment—not stressing over tech settings or surprise bills. Whether you’re heading to the Caribbean, Alaska, Europe, or beyond, take a moment to turn off cellular data roaming before your ship departs. Your wallet will thank you.
