Use both, each where it works: ship Wi-Fi covers you at sea, and a travel eSIM covers you in port and on land across multiple countries. Maya’s one global eSIM, with unlimited data across 165+ countries, priced flat by trip length from USD 9.99, is the one to install once and keep. The USD 9.99 start is a land plan, and coverage on the ship itself is the Global + Cruise plan, a separate purchase. The trap on a cruise is paying for a connection that stops at the gangway. Pick by where you’ll be, not by which sounds cheaper.
Where does cruise Wi-Fi work, and where does an eSIM take over?
Ship Wi-Fi is for the deck, and an eSIM is for everything past the gangway. Maya’s Global + Cruise plan also puts the same eSIM on 20+ cruise lines with unlimited data at sea, so the one you install for the ports can ride along on the ship.
The word to watch is “plan.” Cruise coverage is the Global + Cruise plan, bought on its own. A regular Global plan covers your ports and your days on land, and it does not cover the ship.
Here’s the trip in three stretches:
- At sea: ship Wi-Fi, or Maya’s Global + Cruise plan on 20+ cruise lines.
- In port: the eSIM, in each country you dock in.
- On land before and after: the same eSIM, no swapping.
Maya Mobile is a travel eSIM giving unlimited data in 165+ countries and 20+ cruise lines through a single eSIM permanently installed on the phone. You don’t juggle a ship login, a local SIM and a café password. You keep one eSIM and pick the plan for the stretch you’re on.
What does a cruise Wi-Fi package cost compared with a trip eSIM?
A Maya trip plan is flat by length, not by country. Land plans run USD 9.99 for 3 days, USD 19.99 for 7 days, USD 27.99 for 14 days and USD 49.99 for 30 days. Cruise coverage is priced on its own: the Global + Cruise plan is USD 49.99 for 3 days, USD 109.99 for 7 days and USD 299.99 for 30 days, as published.
Keep those two price lists apart. A Global plan price is never the price of cruise coverage. If you only need data in port and on land, the land plan covers you. If you want the eSIM working on the ship too, that’s the Global + Cruise line.
Every plan includes a daily high-speed data allowance, the Daily Quota, at up to 4G LTE or 5G where local networks offer it. It resets every 24 hours, and data continues at standard speed once it’s used. Maya’s Unlimited eSIM plans, including add-ons like Global Cruise Connectivity, are built for individual travelers using data on the move.
Displayed prices include applicable taxes unless checkout states otherwise. Add-ons are bought separately and have their own availability and conditions.
What happens to your phone data in each port of call?
Your data keeps working in every port, because one Maya eSIM covers 165+ countries at the same price. You installed it before you left, so a new country is not a new purchase. Same eSIM, same price, every country.
Maya eSIMs work in the Caribbean, Spain, Italy, Asia and Puerto Rico, plus 165+ destinations worldwide. One plan covers multi-country travel, so adding a country keeps the same plan and eSIM, and extending a trip needs another plan on the same eSIM. Maya connects you to the best available local network.
That is the part ship Wi-Fi can’t touch. A ship’s connection stays with the ship, and a Mediterranean loop touches several countries in a week. Gary H. gave Maya Mobile five stars on Trustpilot on January 29, 2026: “This esim was just perfect for my needs, worked as expected and was fantastic on every Island we visited except one, which wasn’t on the list anyway.”
A port day is when you want maps, a taxi app and a photo upload to a family chat. Land, switch on, go.
Can you use Wi-Fi calling and messaging at sea with an eSIM installed?
Yes for apps, no for a phone number. A Maya plan is data only, so calling and text messaging aren’t included. You can still browse the web, get directions and use other apps over data.
The plan doesn’t provide a phone number for calls or SMS, and it isn’t meant to be enabled for iMessage. Sending iMessages directly through the eSIM line will fail. Your home SIM keeps your number, and Maya runs alongside it with no SIM removal.
Roaming charges are the bill people fear most. Your home carrier adds no roaming charges for data while the Maya eSIM carries it and Data Roaming is off on your home line. That holds when the eSIM is installed and configured correctly.
Calling and texting with your regular number over Wi-Fi Calling works only if your carrier supports it, and some carriers charge international SMS fees even then. Ask your carrier before you sail.
What should you set up before you board a cruise?
Install the eSIM once, before you travel, on Wi-Fi. The steps are short and done once.
Apple’s published steps for iPhone, from Apple’s Set up eSIM on iPhone support page (2026), start from a new iPhone setup:
- Turn on and set up your iPhone.
- When the Set Up Cellular screen appears, tap Use QR code.
- Follow the onscreen instructions.
To activate your eSIM after setting up your iPhone, get a QR code from your carrier, then:
- Open the Camera app and scan your QR code. When the Cellular Plan Detected notification appears, tap it.
- If you’re using iOS 17.4 or later and get a QR code in a default email app or browser, tap and hold the QR code. Then tap Add eSIM.
- Tap Continue at the bottom of the screen.
- Tap Add Cellular Plan.
Apple lists an iPhone XS, XS Max, XR or later and a carrier that supports eSIM as requirements. The phone must also be on Wi-Fi or a hotspot.
On arrival, turn the Maya eSIM on and choose it for Cellular Data, which starts the plan clock; the connection then comes up within a couple of minutes. If there’s no data, check that the Maya eSIM is switched on and selected for Cellular Data. Keep the eSIM installed afterward, so it’s ready for your next trip.
What do cruisers say went wrong with other travel eSIMs?
The common failure is buying a plan for a cruise that was never built for one. A one-star Trustpilot review of GigSky from October 5, 2026 reads: “Absolute worst esim service that I have ever used. Wasted money purchasing 30gb for 30 days while at sea on Royal Caribbean’s Liberty of the Sea. Purchased 1 day internet from RCCL to write this review. I moved around the ship with no improvement in service. I contacted Customer Service and the email indicated they will give me a refund to my credit card. It may take 5 to 10 days according to email”
Read what that traveler paid for. He bought a data pack and expected it to work on the ship. Maya’s line is plain: at sea, you need the Global + Cruise plan, bought as such. It’s a different purchase from the land plan, and we say so before you pay.
Which travel eSIM suits a cruise itinerary?
For a multi-country cruise, the one that stays installed and covers the ship, the ports and the days either side. Maya covers 20+ cruise lines with the Global + Cruise plan, and the same eSIM works in 165+ countries on land. Install once, and for each trip you only buy a plan.

How Maya Mobile covers the ship, the port and the beach with one eSIM
You came here to find out which connection works where, and Maya’s answer is one eSIM installed once. Maya Mobile is a travel eSIM giving unlimited data in 165+ countries and 20+ cruise lines through a single eSIM that stays on your phone permanently. For each trip you buy a plan, with no reinstalling.
At sea, that plan is Global + Cruise. In port and on land, it’s the flat-priced plan for your trip length. Either way, the same eSIM is already on your phone, and it works alongside your home SIM.
Kristie K. gave Maya Mobile five stars on Trustpilot on May 30, 2026: “Maya Sim was easy to purchase and set up. Their step by step instructions made it easy. I have used Maya sim multiple times now and will definitely use them again!”
Frequently Asked Questions
Does the eSIM renew on its own after my trip?
No. Maya plans are one-time purchases, and you aren’t charged automatically after a plan ends unless you turn on Auto Top-Up. Auto Top-Up is opt-in and off by default.
What if I need more data than my plan covers?
Buy another plan from the Maya app if you need more days. Maya plans are one-time purchases, so nothing is charged automatically when a plan ends unless you turn on Auto Top-Up.
Does one eSIM work across every port on a multi-country cruise?
Yes, with the right plan. Maya Mobile gives unlimited data in 165+ countries and 20+ cruise lines through a single eSIM, and cruise coverage means the Global + Cruise plan as a separate purchase. Service in a specific country isn’t guaranteed and can vary for reasons outside Maya’s control, and no speed is guaranteed. At sea, speeds can differ from land, and cruise connectivity runs on satellite and maritime networks, so it depends on the vessel and route.
Maya gives one eSIM that stays on your phone for the ship, the ports and the days on land.
