QUICK ANSWER
The best way to get internet on a cruise without buying the ship's WiFi package is an eSIM — a digital data plan that connects via the maritime cellular network on your ship, independently of the cruise line's own system. Two providers cover almost every major cruise line: GigSky (most lines, from $19.99) and Red Bull Mobile (Cunard, P&O and Telenor Maritime ships, from euro 15 for 1GB).Ship WiFi costs $20 - $40 per device per day. A GigSky 15-day cruise plan costs around $60 total — under $4 a day — and can be hotspotted to cover every device you bring. On our 14-night Cunard sailing we paid euro 20 total versus euro 370+ for the ship's package. Use code LUXURYCRUISING at GigSky for 10% off.
“$392 USD. For WiFi. On one device. For 14 nights. And that was the pre-purchase discounted price — ad hoc daily use would have been $40+ a day.”
That was the quote we faced before our 14-night Cunard voyage. I’ve been cruising for over 30 years — 700+ days at sea across Seabourn, Silversea, Oceania, Regent Seven Seas and others — and cruise ship internet pricing has always made me wince. So we did what any sensible person would do: ignored the package entirely and started researching alternatives.
What we found was an eSIM. We’ve now used this approach across multiple cruises on Cunard and other lines. It has consistently delivered, and it’s now the first thing we set up before every voyage. In this guide I’ll walk you through exactly how it works, which providers to use, what it costs, and what to realistically expect at sea.
How to Get Internet on a Cruise Without Buying the WiFi Package
The answer is an eSIM — a digital SIM card downloaded directly to your smartphone. No physical card, no queuing at a phone shop, no hunting for a local SIM at the cruise terminal.
Certain eSIM providers have agreements with the maritime cellular networks that operate on cruise ships. These are completely separate from the cruise line's own satellite WiFi system. Your phone connects to them directly and independently — and you pay the eSIM provider's rate, not the cruise line's. Your regular phone number, calls, and texts remain active on your existing SIM at all times. The eSIM simply adds a separate data connection alongside it.
The result: messaging, email, social media, WhatsApp calls, FaceTime audio, and port navigation — all for around $4 a day instead of $28-$40.

The Two eSIM Providers You Need to Know
Which provider you need depends entirely on which maritime cellular network your ship uses. There are two main networks and one main provider for each.
1. GigSky — for Cellular at Sea ships (most cruise lines)
GigSky is the provider we recommend for the majority of cruisers. It connects via the Cellular at Sea network — used by most major lines including Seabourn, Silversea, Oceania, Regent Seven Seas, Celebrity, Holland America, MSC, and most Royal Caribbean group ships.
- Covers 290+ cruise ships via the Cellular at Sea network
- Land data in 190+ countries on the same eSIM — separate plan
- Cruise + Land bundle — switches automatically when you step ashore
- Cruise plans from $19.99 — choose 512MB to 20GB
- Free trial: 100MB globally, up to 500MB in 42 European countries — no credit card required
- Highly rated on Trustpilot

2. Red Bull Mobile — for Telenor Maritime ships (including Cunard)
Red Bull Mobile Data is the one to use for Cunard and any ship on the Telenor Maritime network. Covers over 150 cruise ships and ferries worldwide. Pricing is refreshingly simple.
- Works on Cunard, P&O Cruises, Ambassador, Viking Ocean, and some Costa ships
- 250MB Maritime package — €5
- 1GB Maritime package — €15 (valid 30 days from activation)
- Separate land packages available for port destinations in-app
- App alerts you at 80% data usage — no bill shock
On our 14-night Cunard cruise I used the 1GB package (€15) and topped up once with 250MB (€5). Total ship data spend: €20. The equivalent Cunard WiFi package would have been €370+
Cruise Ship WiFi vs eSIM: What It Actually Costs
Let's put the numbers side by side — because this is where the argument for eSIMs becomes very difficult to ignore.
| Option | Typical Cost | Data | Works Ashore? | Multiple Devices? |
|---|---|---|---|---|
| Cruise Line Premium Wi-Fi (14 nights, 1 device) | ~$392 USD | Unlimited, shared ship network | No | No — per device |
| Cruise Line Daily Wi-Fi (ad hoc, 1 device) | $40 USD/day | Varies by line | No | No — per device |
| Cruise Line Essential Plan (14 nights, 1 device) | ~$280 USD | Basic speeds only | No | No — per device |
| GigSky Cruise eSIM — Cellular at Sea | from $18.99 USD Save 90%+ | 512MB to 20GB, your choice | Yes — with land plan | Yes — via hotspot |
| Red Bull Mobile Maritime — Telenor (Cunard) | from €15 EUR Save 95%+ | 1GB, valid 30 days | Yes — with land plan | Yes — via hotspot |

How Much Data Do You Actually Need?
This is the question every cruiser asks and almost nobody answers directly. Here is what we have found across multiple sailings:
Using eSIM Data When You Go Ashore
This is where the eSIM approach pulls well clear of anything the cruise line offers. The moment you step off the gangway, ship WiFi stops. Your home carrier's roaming — if not included in your tariff — can be expensive. An eSIM solves both problems simultaneously.GigSky's Cruise + Land plan is the slickest option: one plan covers you both at sea and in every port you visit, switching automatically when you step ashore — no manual changes, no fiddling with settings. Alternatively, GigSky country plans give you targeted data for each destination. On a recent Spain and Portugal sailing, I paid roughly $8 USD for a 3GB 15-day Spain plan and slightly less for Portugal. Both activated the moment we docked and worked flawlessly throughout each port day.
Always Enable Airplane Mode the Moment You Board
⚠️ This is not optional: The moment you step onto any cruise ship, enable airplane mode. If you leave mobile data on, your phone will automatically connect to the ship’s maritime cellular network and your home carrier will bill you at international roaming rates. These charges appear on your next phone bill — not your onboard account — and can be extremely expensive.
What we do on every sailing, without exception:
- Enable airplane mode the moment we board.
- Manually turn WiFi back on — to connect to ship WiFi if using a package, or to nothing if using an eSIM at sea.
- For eSIM users: enable the eSIM data plan in Settings. It activates automatically once the ship reaches international waters (12+ nautical miles from shore).
- Home carrier data roaming stays off for the entire voyage.
4 Things You Need Before You Use a Cruise eSIM
- An eSIM-compatible phone. Most smartphones from 2019 onwards support eSIM. For iPhone that means XR, XS, 11 and above. Android compatibility varies by manufacturer — check your specific model on the GigSky website before purchasing.
- An unlocked phone. Your device must be network-unlocked to use a third-party eSIM. iPhone: Settings → General → About → Network Provider Lock (look for “No SIM restrictions”). Android: Settings → Connections → Mobile Networks → Network Operators.
- Confirmed coverage for your ship. GigSky covers 190+ countries on land and 200+ cruise ships at sea. Verify your specific vessel at gigsky.com before purchasing.
- Know your ship’s maritime network. Most lines use Cellular at Sea → GigSky. Cunard, P&O, Ambassador, Viking Ocean, and some Costa ships use Telenor Maritime → Red Bull Mobile. If in doubt, check both providers’ ship lists — it’s on their websites.
eSIM Readiness Checklist — Before You Board
- Phone is eSIM-compatible (iPhone XR/XS/11+ or compatible Android)
- Phone is network-unlocked — confirmed in Settings
- Ship's maritime network identified (Cellular at Sea or Telenor Maritime)
- Correct eSIM provider chosen and plan purchased
- eSIM installed and tested at home before departure
- Offline maps downloaded (Google Maps or Apple Maps) for each port
- Netflix / Spotify content downloaded before sailing
- Code LUXURYCRUISING used at GigSky for 10% off
How to Set Up Your Cruise eSIM: Step by Step
Do all of this at home, before you travel. You need a WiFi connection to install an eSIM — do not leave it until you are at the port.
- Download the app. Get the GigSky app from the App Store or Google Play. For Cunard/Telenor ships, download the Red Bull Mobile Data app instead.
- Choose your plan. For GigSky: select a cruise plan for your sailing region (Americas & Caribbean, Europe, Asia Pacific, etc.), plus a land plan or Cruise + Land bundle for port days.
- Apply your discount. At GigSky checkout, enter code LUXURYCRUISING for 10% off.
- Install the eSIM. Follow the in-app instructions — either scan the QR code emailed to you or install directly through the app. You only do this once. Future plans are loaded through the same app without reinstalling.
- Test before you travel. GigSky’s free trial (100MB–500MB depending on your region, no credit card needed) is ideal for confirming everything works before you commit to a paid plan.
- At sea. Enable airplane mode when you board. Turn your eSIM data plan on in Settings. The maritime plan activates automatically once the ship is in international waters. That’s it.
Both GigSky and Red Bull Mobile send push notifications when you are approaching your data limit — you can top up before you run out.
What to Realistically Expect — The Honest Version
What works reliably: emails, WhatsApp and iMessage (text and voice), social media browsing with video autoplay off, Google Maps in ports, FaceTime audio, Messenger and WhatsApp voice calls. All of these worked consistently across our sailings on both Cunard (Red Bull Mobile) and Cellular at Sea lines (GigSky).
What doesn’t work well: video streaming at sea is not what this is designed for. Speeds are broadly comparable to a 4G connection — not fibre broadband — and attempting to stream will burn through your allowance quickly. Signal strength varies by deck: outdoor decks consistently outperform interior cabins on lower decks.
vs ship WiFi for streaming: Cruise lines with Starlink (Cunard SpaceEx, Royal Caribbean VOOM, Celebrity) will be faster for video streaming. The eSIM is not competing on that front. It competes on price — and on the fact that it keeps working when you step off the ship, which ship WiFi will never do.
The honest summary: we would rather pay €20 for reliable messaging, email and social media at sea than €370+ for overcrowded ship WiFi. That has been true on every sailing we have tried it.
Which Cruise Lines Work with GigSky?
GigSky works on 200+ cruise ships via the Cellular at Sea network. Verify your specific ship at gigsky.com before purchasing. As a general guide:
- Cellular at Sea → GigSky: Seabourn, Silversea, Oceania, Regent Seven Seas, MSC, Celebrity, Holland America, and many others across the Royal Caribbean group
- Telenor Maritime → Red Bull Mobile: Cunard, P&O Cruises, Ambassador, Viking Ocean, some Costa ships
- Lines with WiFi already included in the fare: Silversea, Regent Seven Seas, Seabourn, Celebrity (Always Included). An eSIM is still worth having for port days when ship WiFi doesn’t follow you ashore.
Using GigSky for Land Travel Too
One thing that often surprises people: GigSky is not just a cruise eSIM. The same eSIM covers land-based data in 190+ countries, making it genuinely useful for the journey to and from the ship, pre- or post-cruise hotels, and international travel generally.
GigSky country and regional plans are competitive with the best travel eSIM providers. A 3GB Europe plan covers every port on a typical Mediterranean itinerary. The Cruise + Land bundle goes further — one plan, automatic switchover between maritime and land networks, no manual intervention needed.
For frequent travellers, GigSky One is worth considering: a monthly subscription covering 120+ countries from around $27/month. It covers you at sea and ashore, and cancels at any time with no penalties.
Let Us Answer Your Questions
How do you get internet on a cruise without buying the WiFi package?
The best way is an eSIM — a digital data plan connecting via the maritime cellular network on your ship, independently of the cruise line's own WiFi. GigSky works on ships using the Cellular at Sea network (most cruise lines) from $18.99. Red Bull Mobile works on Telenor Maritime ships including Cunard, with 1GB for €15. Both can be hotspotted to cover all your devices. Use code LUXURYCRUISING at GigSky for 10% off.
How much can I save using an eSIM instead of cruise ship WiFi?
Significantly. Cruise lines charge $20–$40 USD per device per day. On a 14-night cruise a single-device package costs $280–$560 USD. A GigSky 15-day cruise eSIM plan costs around $60 total — under $4 per day — and can be hotspotted to cover multiple devices. We spent €20 on a 14-night Cunard sailing versus €370+ for the ship's WiFi package.
Which cruise lines work with GigSky?
GigSky works on ships using the Cellular at Sea network — most major lines including Seabourn, Silversea, Oceania, Regent Seven Seas, MSC, Celebrity, Holland America, and many in the Royal Caribbean group. Cunard, P&O, Ambassador, and Viking Ocean use Telenor Maritime instead — for those, use Red Bull Mobile. Always verify your specific ship on the GigSky or Red Bull Mobile website before purchasing.
Does the eSIM also work ashore in cruise ports?
Yes — this is one of the biggest advantages over ship WiFi, which stops working the moment you step off the gangway. GigSky country and regional plans activate automatically when you step ashore, giving you full 4G/5G speed for navigation, messaging and social media throughout the day in port. GigSky's Cruise + Land bundle covers both at sea and ashore on a single plan with automatic switchover.
How much data do I need for a cruise?
For emails, messaging, social media with video autoplay off, and occasional voice calls, most passengers use 1–3GB over a 7–14 night cruise. Add roughly 200–400MB per port day for navigation and browsing ashore. Do not plan to stream video on a cruise eSIM plan — download Netflix, Spotify and offline maps before you sail.
Can I use an eSIM to get internet for my laptop or tablet on a cruise?
Yes. Once your eSIM is active on your smartphone, enable Personal Hotspot and your laptop, tablet, Kindle, or partner's phone can all share the connection. Cruise lines charge per device for their WiFi packages — with an eSIM, one plan covers everyone travelling with you, which effectively doubles or triples the value.
Do I need to set up the eSIM before I board?
Yes — you need an internet connection to install an eSIM. Do it at home before you travel. Use GigSky's free trial (100MB–500MB depending on region, no credit card needed) to confirm everything works before purchasing a paid plan. The eSIM activates automatically once the ship reaches international waters.
Should I put my phone on airplane mode on a cruise?
Yes — always. Enable airplane mode the moment you board. If you leave mobile data on, your phone connects to the ship's maritime cellular network and your home carrier bills you at international roaming rates — these appear on your next phone bill, not your ship account, and can be very expensive. After enabling airplane mode, turn WiFi back on manually, or activate your eSIM data plan if you are using one.
Is It Worth It? Our Verdict After Multiple Sailings
We went into our first cruise eSIM experiment with genuine uncertainty. After doing it across multiple sailings on Cunard, Seabourn, and other lines, it is now non-negotiable — the first thing we set up before every voyage. The economics make it very hard to argue against. Whether you are spending €20 with Red Bull Mobile on a Cunard Telenor Maritime sailing or $30–$60 with GigSky on a Cellular at Sea ship, you are saving hundreds versus the cruise line's own packages. And you get something ship WiFi will never provide: internet that follows you off the ship and into every port on your itinerary.The honest trade-off: it is not a streaming solution. Download your content before you sail. But for everything else — emails, WhatsApp, social media, voice calls, port navigation, staying in touch with home — it is more than adequate, and the price difference is not close.
