Stored prices may have changed. Google Fi is excluded from the value ranking because it is a full phone plan rather than a travel data plan.
What if it was just $5.00 a GB, everywhere?
We are considering a BetterSIM eSIM at one flat rate worldwide. No tiers, no bundles, no per-country price shopping, no volume discounts you never reach. The same $5.00 in Cruise Ship as in Fiji or Kenya.
Straight answer: this would not be the cheapest option. The plans listed on this page are often less per GB, especially in Europe and Asia. It would be the simplest. Savings against Google Fi depend on usage, Bill Protection and speed needs.
Local Network Insights
Cruise-focused eSIM plans partner with maritime networks such as WMS and Telenor Maritime for at-sea coverage, while docking brings you onto carriers like Digicel, AT&T, or Vodafone depending on the port. Preloading an eSIM means you stay connected without scrambling for short-lived shipboard Wi-Fi passes.
Connectivity Overview
Staying connected on a cruise ship is fundamentally different from land-based travel. Almost all major cruise lines now use Starlink for their onboard internet, which has dramatically improved at-sea speeds compared to the older satellite systems. That said, bandwidth is still shared among thousands of passengers, so expect speeds closer to basic 4G rather than the fiber-like performance Starlink delivers on land.
eSIM providers like GigSky offer dedicated maritime plans that connect through the ship's cellular-at-sea infrastructure. GigSky is particularly strong here because its MVNO partnerships with maritime networks like Wireless Maritime Services give it direct access to the ship's Starlink-backed cellular system. Cruise line Wi-Fi packages typically run $10-20 per day for basic access, so comparing that against an eSIM maritime plan is worth doing before you board.
Every time your ship docks at a port, your eSIM switches to the local land-based network where speeds are fast and costs are normal. Smart cruisers use port days for data-heavy tasks like uploading photos, video calling family, and downloading content for the next sea day. Planning your connectivity around the itinerary is the key to staying connected without overspending.
Practical Data Tips
- Download movies, podcasts, playlists, and reading material before boarding - even with Starlink, shared bandwidth can be slow during peak hours
- Use port days strategically for uploading photos, video calls, and downloading content for the next sea day
- Compare the ship's Wi-Fi package cost against a GigSky maritime eSIM plan - one may be significantly cheaper
- Disable automatic app updates, cloud photo sync, and background data to avoid burning through expensive at-sea data
- Many ports have free Wi-Fi near the cruise terminal - use it for quick uploads and messages before reboarding
At a Glance
Average Data Cost
~$22/GB
Network Quality
At sea: Starlink-backed, usable for messaging and browsing but shared among all passengers. At port: standard land-based 4G/5G speeds via local carriers.
eSIM Availability
Maritime connectivity now primarily runs through Starlink satellite infrastructure. eSIM connectivity at sea requires plans that specifically include maritime coverage. Standard land-based eSIM plans do not work at sea.

Before you fly: a 6-step checklist
- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the Cruise Ship eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Choose your travel data line.
On iPhone, select your travel eSIM in Settings > Cellular > Cellular Data. Follow your provider's roaming and activation instructions. Choosing a data line does not by itself prevent charges on your home line.
- 4
Decide whether to keep your home line on.
You do not need to disable iMessage simply because you use a travel eSIM. Apple’s travel eSIM guidance says iMessage and FaceTime can continue using your home line while traveling. If you keep both lines active for home-number calls or SMS, your carrier may charge roaming fees. Check your carrier’s terms before leaving your home line on.
- 5
Download offline maps for Cruise Ship.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.

How we built this page
Country plan prices come from stored supplier snapshots. The catalog contains different data amounts and validity periods. Provider ordering uses the unweighted average $/GB of fixed plans, or the PAYG rate; unlimited plans are excluded from that average. Check a plan’s data, validity and total price against your trip before buying.
