The Stena Line crossing from Hoek van Holland to Harwich takes about seven hours.  Somewhere in the middle of the North Sea, roughly two hours out, every normal travel eSIM I have ever carried goes dark. Ship wifi wanted €19 for the crossing. 

My GigSky ferry plan was already running, because I had installed it the night before in a hotel in Rotterdam. That is the part most people get wrong.

Short version

Use ESIMADVICE15 at GigSky checkout for 15% off any plan — land, cruise, ferry or offshore. It works for new and existing customers and there is no minimum spend. It applies to single-country plans and regional bundles alike.

But before you pay for anything: check whether your Visa card already gives you GigSky data for free. Since April 2026, eligible Visa cardholders get 3 to 7 days of unlimited data in participating countries at no cost, plus 20–30% off everything else.

Some US card issuers give 3–5GB every month. Most people who buy a GigSky plan never check, and a lot of them are paying for data they already own.

Check the card first. Use the code on whatever the card doesn’t cover.

GigSky Visa benefits: check your card first

This is the part nobody writes about, and it is worth more than any coupon.

On 1 April 2026 Visa and GigSky launched Visa Destinations — a benefit attached to eligible Visa cards that gives complimentary unlimited data in participating countries.

What your Visa card gets you

Card tier	Complimentary unlimited data	Discount on other GigSky plans
Visa Infinite (consumer or commercial, incl. Canadian Infinite Privilege)	7 days unlimited	30% off
All other eligible Visa cards — Signature, Platinum, Gold, Classic, debit, prepaid	3 days unlimited	20% off

The discount applies automatically at checkout once your card is verified. No code needed, and GigSky states it does not expire while you remain an eligible cardholder.

Which countries participate?

GigSky’s own pages are not consistent on this. The FAQ on the Visa Destinations page still says four countries. Their benefits page and issuer pages say six. The terms page phrases it differently again.

The list you should work from:

Visa says more destinations are being added.

One thing to be clear about: the expanded North America coverage ran as a World Cup promotion from 1 April to 31 July 2026. That window has now closed. Check the current list in the app before you count on Canada or Mexico.

Card issuer programmes — this is where the real value sits

Beyond the Visa Destinations benefit, individual issuers run their own GigSky programmes. Several are considerably more generous.

Issuer / card	What you get
U.S. Bank Altitude Connect Visa Signature	5GB every month across 175+ countries, plus 20% off all plans including cruise
UBS Visa Infinite	5GB / 30-day complimentary plan, plus 30% off including cruise
Navy Federal Visa Signature Flagship Rewards	3GB / 15 days in 175+ countries, plus 20% off including cruise
CAIXA Visa Infinite (Brazil)	Two 3GB / 15-day plans, plus 30% off including cruise
CAIXA Visa Platinum (Brazil)	Two 1GB / 15-day plans, plus 30% off including cruise
Chime Visa Signature	1GB split across up to four separate plans, 15-day validity, plus 20% off
Visa USA — Infinite	3GB / 15-day global plan once per calendar year, plus 7 days unlimited at Visa Destinations, plus 30% off
Visa USA — Signature	1GB / 15-day global plan once per year, plus 3 days unlimited, plus 20% off
Visa Canada — Infinite Privilege	1GB / 15-day plan twice per year, plus 30% off
Visa Canada — Platinum / Classic / Gold / debit	10% off only
Visa LATAM / Caribbean / Brazil — Infinite Private & Privilege	3GB / 15-day plan, 7 days unlimited, a 365-day Travel Essentials plan, plus 30% off
Visa Argentina — Signature	3GB / 15-day, 7 days unlimited, plus 30% off
Visa Japan — Infinite and Signature	3GB or 1GB / 15-day, up to 7 days unlimited, plus 30% off

If you hold a U.S. Bank Altitude Connect card and travel monthly, that is 60GB of international data a year you are entitled to and probably not claiming.

How to check your eligibility

If your Visa card lives in Apple Pay or Google Pay, you need to add the card directly inside the GigSky app — the digital wallet alone will not verify it.

The catch on the Visa benefit

Every benefit has limits, and these ones are worth knowing before you plan a trip around them.

How to apply the GigSky promo code

If your Visa card doesn’t cover your destination, or you need more data than the free allowance, the GigSky promo code is the next lever. ESIMADVICE15 goes in the same field wherever you buy.

In the GigSky app:

On gigsky.com

If the code doesn’t apply

What happened	Why	What to do
Nothing changes on the total	Lower-case entry or a trailing space	Retype in capitals
Code applies but the discount looks smaller	Your Visa benefit discount is already active and is larger	Keep the Visa one — 20% or 30% beats 15%
Code rejected	Another promotion already on the cart	One discount per order. Remove the other
You’re on a complimentary Visa plan	Free plans have nothing to discount	Nothing to fix. It’s already free

Don’t assume a total that didn’t move will correct itself at payment. It won’t. Fix it before you confirm.

What GigSky actually sells?

GigSky sells prepaid mobile data abroad in 200+ countries and regions — no contract, no international roaming bill — and it offers more plan types than almost anyone else in this category. That breadth is the reason to use it.

Plan type	What it covers	Starting price
Country	Single destination, 200+ available	From $3.99
Regional	North America, Europe, Caribbean, Middle East, APAC, Africa, LATAM	Varies
Global / World	Multi-continent coverage	Varies
Cruise + Land	290+ ships plus the countries you dock in	From $18.99
At Sea Only	Ship coverage without land	From $19.99
Ferry	Brittany Ferries, Color Line, DFDS, Stena Line	From $7.99
Inflight	New; in-flight connectivity	From $13.99
Offshore	North Sea, Gulf of Mexico and similar	From $9.99
GigSky One	Global monthly subscription	$33.99/month

Plans are data-only — no voice, no SMS. GigSky does not run a conventional top-up system: when a plan runs out you buy another, and the code applies again. There is a free trial: a 100MB plan with no credit card required, and a 500MB free plan currently listed. Try that before you spend anything.

Cruise plans: where GigSky has no real competitor

Almost nobody else sells a proper cruise eSIM. GigSky covers 290+ ships across Royal Caribbean, Carnival, Disney, Celebrity, MSC, Norwegian, Princess and P&O.

There are two shapes. Cruise + Land covers the ship and the countries you dock in — Americas and Caribbean spans 48 countries, Europe 44, Asia Pacific 25, Middle East 9, and the World plan reaches 128. At Sea Only covers the ship alone.

Plans run from 512MB to 20GB, over 1 to 120 days, priced from about $18.99 up to $254.99 for the largest tiers.

Cruise option	Typical cost
Cruise line’s own wifi package	$12–$20 per day
A 7-day cruise on ship wifi	$200–$300
GigSky Cruise + Land, entry tier	From $18.99 — $16.14 with ESIMADVICE15
GigSky Cruise, larger tiers	Up to $254.99 — $216.74 with the code

Two honest limitations before you buy. Cruise speeds run around 700 Kbps to 4 Mbps — fine for messaging, maps and email, not for video calls. And there is no connectivity within 12 nautical miles of shore, which is exactly when you are pulling into port and want it most. Buy a land plan for the port days, or a Cruise + Land bundle that covers both.

Ferry plans: the one almost nobody knows exists

GigSky sells ferry data from $7.99, covering Brittany Ferries, Color Line, DFDS and Stena Line. It works on deck offshore, while docked in port, and hands over to normal land coverage when you disembark.

Install it before you board. It activates automatically once you are on the ship. If you have ever crossed the Channel, the Baltic or the North Sea and watched your phone lose signal an hour out while the onboard wifi asked for €19, this is the fix. With ESIMADVICE15 the entry plan is $6.79.

US ferry routes are listed as temporarily unavailable at the moment.

GigSky One: the subscription option

If you are abroad more than you are home, the per-trip model stops making sense.

GigSky One plan	Monthly price	With ESIMADVICE15
25GB	$33.99	$28.89
50GB	$53.99	$45.89
75GB	$73.99	$62.89

Covers 120+ countries, billed monthly, quarterly or annually, cancel anytime. Past your allowance it keeps working at up to 1 Mbps rather than cutting off.

Worth it if you travel more than roughly ten days a month. Skip it if you take two trips a year — buy country plans and use the code.

GigSky Business and enterprise plans

GigSky’s enterprise arm is a genuinely different product, not a rebadged consumer plan. It runs multi-IMSI across 800+ operators in 200 countries with dynamic carrier switching and automatic failover, plus data-centre redundancy in North America and Europe.

The controls sit on the SIM rather than the device — whitelisting, blacklisting, VPN tunnels, routing rules. There is a management portal with REST APIs, and automated eSIM deployment through Jamf, InTune and SOTI. Pricing is by quote, with a published self-serve per-GB list for teams that want it without a sales call.

It is aimed at aerospace, defence, financial services, healthcare, hospitality, petroleum and retail — organisations where a phone dropping off the network is a real problem. If you are buying for a team rather than yourself, that is the door to knock on.

What the discount is actually worth

Plan	List	With ESIMADVICE15	You save
Country plan, entry tier	$3.99	$3.39	$0.60
Ferry plan, entry tier	$7.99	$6.79	$1.20
Offshore plan, entry tier	$9.99	$8.49	$1.50
Inflight plan, entry tier	$13.99	$11.89	$2.10
Cruise + Land, entry tier	$18.99	$16.14	$2.85
GigSky One 25GB / month	$33.99	$28.89	$5.10
GigSky One 50GB / month	$53.99	$45.89	$8.10
Cruise, premium tier	$254.99	$216.74	$38.25

The pattern is the same as every percentage discount: near-meaningless on a $4 plan, properly useful on cruise and subscription plans. On a family cruise booking two premium plans, the code covers dinner.

Against the alternative

Option	Cost
AT&T international pay-per-use	$2.05 per MB — around $2,100 per GB
AT&T / Verizon international day pass	$12 per day
Cruise line wifi	$12–$20 per day
Industry average, traditional roaming	$8.57 per GB
Industry average, travel eSIM	$5.50 per GB
GigSky country plan, entry tier with code	$3.39

Roughly 90% of mobile users never turn roaming on abroad at all. They switch data off and hunt for wifi. That is the real competition here — not other eSIMs.
