BreezeSim on a cruise — the honest answer
Short answer
BreezeSim sells data-only travel eSIMs for more than 190 countries. It also runs the eSIM shops behind several big brands, including SWISS, Wizz Air and du. You install it by scanning a QR code, and the clock only starts when you first use it. Tethering is free on every plan. It runs on land networks, so it covers your port days and nothing in between.

Overview
BreezeSim sells prepaid data plans on breezesim.com. It also licences the same system to other companies. That is why a search for the SWISS eSIM, the Wizz Air eSIM or the du eSIM leads you back to a Breeze-run shop. Coverage reaches more than 190 countries. That includes North America, Europe, Asia, the Middle East, Africa and the Caribbean. You can buy single-country, regional or global plans.
Plans come in three shapes. There are fixed bundles with set data and set days. There are day plans that give you 1GB every 24 hours. And there are Premium Unlimited tiers, which pair unlimited data with a high-speed cap. Your days only start counting when you first use the plan. So you can buy and install it well before you travel without wasting a single day.
Coverage on a cruise
A BreezeSim eSIM uses local carrier partners in each country. In the US that means Verizon Wireless and AT&T Mobility. You get 4G LTE, or 5G where it exists. It is the same coverage a normal roaming SIM would use. On a cruise, that means it wakes up as you come into port and goes quiet as you head back out. Land masts reach about 12 nautical miles, and no further. BreezeSim has no maritime layer in any plan, so a full day at sea sits outside everything it sells.
Plans and pricing
Plans start at $3.99. On the US page you will find 10GB over 30 days for $13.99, down from $19.00. Canada is $14.99 for 10GB over 30 days. Europe Lite is $12.99 for the same amount (checked September 2026). Global plans start at $10.99. Premium Unlimited runs from 30GB of high-speed data over 5 days up to 90GB over 15 days. Once you pass the cap, data keeps flowing at a slower speed.
Your validity starts on first use, not at checkout. Buy a plan weeks before a cruise and it will not tick down until your phone connects. Need more data mid-trip? You add it in the Breeze dashboard rather than buying a second eSIM. And if you never touch a plan at all, BreezeSim refunds it in full, back to your original card within three working days.

Setup and activation
You buy on the website and install by scanning a QR code. BreezeSim says the eSIM goes live in under 60 seconds once it finds a covered network. Set it up at home on your own wi-fi, not when you land. Because the clock does not start until first use, installing early costs you nothing.
On a cruise that timing works in your favour. Install before you board and leave the profile sitting there quietly. Your 30 days then begin at the first port, not on the day you paid.
Strengths and limits
- Your days start on first use, so early setup costs nothing.
- Tethering is free on every plan.
- Full refund if you have not used any data.
- Runs the eSIM shops for airlines like SWISS and Wizz Air.
- There is no app, so everything happens in a browser.
- No calls or texts, so keep your normal SIM switched on.
- No BreezeSim plan covers a full day at sea.
- 5G depends on the local network, so it varies by country.
Cruise and ferry plans
The plans database on this site holds cruise, ferry and maritime products only. BreezeSim publishes none, so there is no plan table on this page. Its regional data plans remain the relevant purchase for port days.
Verdict
BreezeSim suits a cruise passenger who likes to get things sorted early. You can install it weeks ahead without losing days, tethering is free, and the no-data-used refund is written down rather than implied. The gaps are clear enough. There is no app, and no calls or texts. It also goes quiet the moment you leave the coast, so you will still want a maritime eSIM or the ship wi-fi for your sea days.
What to pair this with for sea days
For the hours between ports you need one of the three maritime providers:
Frequently asked questions
01Does BreezeSim work on a cruise ship?+
Partly. It handles the half of a cruise that happens on land, which on a port-heavy itinerary is most of the waking hours — but the sea days need a plan BreezeSim does not sell.
02When does the BreezeSim clock actually start?+
It starts the first time your eSIM connects to a network in the country you are visiting, not when you pay. So you can buy and install weeks before a cruise. Your days only begin once you reach a covered port.
03Can I get a refund on a plan I never used?+
Yes. If you have used no data at all, BreezeSim refunds the full amount to your original card within three working days. That is a clearer promise, in writing, than most eSIM shops offer.
04Are BreezeSim eSIMs sold under other names?+
Yes. Breeze runs white-label shops for airline and telecom partners. The SWISS eSIM, the Wizz Air eSIM and the du eSIM all sit on the same platform underneath.
05Do I have to buy a new plan to top up?+
No. You add more data to a live plan in the Breeze dashboard, and it takes seconds. There is no need to buy and install a second eSIM in the middle of a trip.
