GigSky keeps coming up whenever we test eSIMs for cruise travel, and there’s a simple reason why: it’s one of the only providers that actually builds plans for life at sea. That’s the part worth knowing before you buy anything.
This review covers how GigSky’s coverage, speed and pricing actually stack up, then gets into the part most people click through for: our exclusive code, CHAMPAGNEMILE, for 15% off, plus a free data trial that doesn’t need a credit card.

Is GigSky Worth It? The Short Answer
If you want the verdict before the detail: GigSky is genuinely worth it if you’re cruising, doing a multi-country Europe trip, or you just want a network that doesn’t drop out in the middle of nowhere. It’s not the cheapest option if you’re only heading to somewhere like Thailand or Vietnam, where resellers like Airalo undercut it by a wide margin. We’ll unpack why below, but that’s the short version if you’re in a hurry.

GigSky eSIM Coverage: Countries, Cruise Lines and Network Quality
GigSky’s land coverage runs across 200+ countries and territories, with its World Plan bundling 163 of them under one eSIM. That’s broad, but the number that actually sets GigSky apart is 280+, which is how many cruise ships it has dedicated plans for, spanning Caribbean, Mediterranean, Alaska and Asia routes. No other major eSIM brand has built a product specifically for cruising, which is why GigSky turns up in almost every cruise forum thread about staying connected at sea.
Part of why the network holds up is that GigSky isn’t reselling someone else’s connectivity. It’s a full Mobile Virtual Network Operator with its own agreements across more than 400 carriers, so when you land somewhere, your eSIM connects to whichever local network is actually performing best rather than a single fixed partner. In everyday use that means maps, messaging and video calls tend to work the way you’d expect, even in regions where budget resellers can be patchy. Hotspot and tethering are included on every plan, which matters if you’re sharing data across a couple of devices while travelling.
The one number worth knowing before you buy an unlimited plan: speeds throttle after 2.5GB of high-speed data in a single day. You’ll still have data, it just won’t be fast enough for heavy streaming until the cap resets the next day.
How to Use a GigSky Promo Code
Applying your GigSky discount takes about a minute. Here’s how:
- Download the GigSky app (iOS or Android) or visit gigsky.com – either works for purchasing plans.
- Create a free account – new users automatically receive a free data trial (100MB globally, 500MB in Europe) added to their account with no credit card needed.
- Select your plan – choose from single-country, regional, global (163 countries), or cruise/inflight plans based on your itinerary.
- Add to cart and proceed to checkout – look for the “Promo Code” or “Discount Code” field.
- Enter CHAMPAGNEMILE – paste the code exactly as shown, click Apply, and confirm the 15% discount appears in your total before completing payment.
- Install your eSIM – after purchase you’ll receive a QR code by email. Scan it via Settings → Mobile Data / Cellular → Add eSIM. Installation takes under two minutes.
- Activate on arrival – enable the GigSky plan in your SIM settings, turn off your primary SIM’s data roaming, and you’re connected. The GigSky app shows remaining data and connection status in real time.
How Much Can You Save with GigSky?
Here’s how the 15% TCM exclusive code and GigSky One subscription translate into real savings across popular plan types:
| Plan | Standard Price (USD) | After 15% Code | After GigSky One (25% off) |
|---|---|---|---|
| 1GB / 7 days (single country) | $8.99 | $7.64 | $6.74 |
| 3GB / 15 days (single country) | $24.99 | $21.24 | $18.74 |
| Europe Regional (unlimited) | ~$35–45 | ~$29.75–$38.25 | ~$26.25–$33.75 |
| World Plan 5GB / 30 days (163 countries) | $84.99 | $72.24 | $63.74 |
| Cruise + Land bundle | $139.99 | $118.99 | $104.99 |
Prices are indicative and may vary. Always confirm at checkout. USD pricing – AUD equivalent will vary with exchange rates.
If you take three or more international trips a year, run the numbers on GigSky One. The 25% ongoing discount tends to beat the one-off code fairly quickly.
Best Ways to Save with Gigsky
Use the TCM exclusive code CHAMPAGNEMILE for 15% off. This applies to all plan types – single-country, regional, global, and cruise bundles – with a minimum $4 spend. It’s the quickest discount available without a subscription commitment.
Start with the free trial before you buy. Every new account gets up to 500MB free (Europe) or 100MB free (everywhere else) with no credit card required. This isn’t just a marketing gimmick – it’s a genuine way to confirm your phone is eSIM-compatible and that GigSky’s network works well in your destination before you spend any money.
Consider GigSky One if you travel frequently. The subscription gives 25% off most plans including cruise plans and shares across one eSIM in 120+ countries. For three or more international trips per year it likely pays for itself.
Choose cruise + land bundles over buying separately. If your itinerary includes both cruise days and shore time, GigSky’s combined cruise and land plans are consistently better value than buying two separate plans – and GigSky is the only major provider offering this.
Activate the Europe free trial for longer stays. The 500MB European trial is meaningful for a day or two of light use. Combine it with hotel and restaurant Wi-Fi and you may not need a paid plan at all for short European city breaks.
Use the referral program for repeat savings. Once you’re a GigSky customer, referring others earns up to 25% off your next purchase – stackable as a long-term savings strategy for regular travellers.

What is GigSky?
GigSky is a California-based travel eSIM provider founded in 2010, making it one of the oldest and most established players in the market. Unlike most eSIM services that resell connectivity from third-party networks, GigSky operates as a full Mobile Virtual Network Operator (MVNO), meaning it manages its own agreements directly with over 400 carriers worldwide. In practical terms, this means faster troubleshooting when connectivity issues arise, and more control over network routing for stable speeds in remote areas.
Coverage spans 200+ countries and territories for land-based travel, with the full World Plan reaching 163 countries under a single eSIM. Plans come in four categories: single-country, regional, global (World Plan), and crucially cruise and inflight. GigSky is the only major eSIM provider with dedicated plans for cruise ships, covering 280+ vessels across Caribbean, Mediterranean, Alaska, and Asia itineraries. They also offer inflight connectivity on select airlines, making them the go-to choice for travellers whose trips include significant time at sea or in the air.
Plan sizes range from 512MB for short weekend trips to unlimited data for extended stays. Unlimited plans operate with a 2.5GB daily high-speed cap – once exceeded, speeds throttle before resetting – which is worth knowing if you plan to stream heavily. Hotspot and tethering are included on all plans.
GigSky holds a 4.3/5 rating on Trustpilot from 3,100+ reviews, with customers consistently praising coverage reliability and the convenience of cruise connectivity. The main criticism in reviews is pricing – GigSky sits in the mid-to-upper range of the eSIM market, particularly for popular destinations in Asia where budget competitors undercut significantly.
A free trial of up to 500MB is available to all new users with no credit card required – an unusually low-risk entry point that speaks to confidence in the product.
Is GigSky Worth It in 2026?
For cruise travellers: yes, unequivocally. GigSky is the only major eSIM provider with dedicated cruise ship plans covering 280+ vessels. If you’ve ever paid $15 per hour for patchy satellite Wi-Fi at sea, GigSky’s combined cruise and land bundles represent genuinely good value and there’s no direct competitor.
For land-only travel: it depends on your destination. GigSky’s reliability as a full MVNO is a real advantage in remote or less-covered regions where reseller eSIMs can be hit and miss. For major tourist destinations in Europe and North America, the network quality is strong and the coverage breadth is excellent. However, in popular Asian destinations like Thailand and Japan, GigSky’s per-GB pricing is noticeably higher than budget alternatives like Airalo or Nomad, sometimes 3–4 times the price for equivalent data. The 15% TCM code helps, but doesn’t close that gap entirely.
For inflight and frequent flyers: GigSky One (the subscription tier) is worth calculating for anyone doing 3+ international trips annually – 25% off ongoing, including cruise plans.
Verdict: GigSky is the best, and really the only choice for cruise itineraries. For land travel in Europe and North America it competes well. For Asia and budget-conscious trips, compare against Airalo or Nomad before committing. Always start with the free trial.
GigSky Pros and Cons
Our take: if your trip involves a cruise, GigSky is close to the only sensible choice, so the decision makes itself. For straightforward land travel in Europe or North America it holds up well against the bigger names. If you’re mainly headed to Southeast Asia and counting every dollar per gigabyte, it’s worth cross-checking against Airalo or Nomad first, since GigSky’s reliability comes at a price premium there.
How GigSky Promo Codes Work and Why Yours Might Not Apply
GigSky codes are entered at checkout in the “Promo Code” field. If CHAMPAGNEMILE or another code isn’t working, here’s what to check:
- Minimum spend not met. The TCM exclusive requires a minimum $4 USD order. Plans below this threshold won’t qualify.
- One use per account. The CHAMPAGNEMILE code is limited to one use per GigSky account. If you’ve used it previously, it won’t apply again on the same account.
- Plan exclusions. The 15% TCM code excludes Inflight plans and North Sea plans. All other plan types -single-country, regional, global, and cruise are eligible.
- Code entered incorrectly. GigSky codes are case-sensitive. Copy and paste rather than typing manually, and check for any leading or trailing spaces.
- Expired code. Promotional codes from other sites may have expired.
- App vs website mismatch. Some codes apply only to purchases made on the GigSky website rather than in-app. If a code isn’t working in the app, try completing the purchase via gigsky.com in a browser.
GigSky’s support team is available 24/7 via the app or website. Note that based on Trustpilot reviews, response times for complex issues can run 12–24 hours, so if you’re troubleshooting before a trip, contact support with some lead time.

Use code CHAMPAGNEMILE for 15% off all GigSky eSIMs, plus a free trial up to 500MB with no credit card required.
Final Thoughts: Best GigSky Deals Right Now
The CHAMPAGNEMILE code for 15% off is the easiest saving available – apply it at checkout on any land-based plan and it works immediately. But the bigger picture with GigSky is the free trial: before spending anything, download the app and claim your 100MB or 500MB free trial to confirm your phone is compatible and the network performs in your destination. If you’re travelling on a cruise, GigSky is essentially the only eSIM worth considering – no other major provider covers 280+ vessels with dedicated plans. And for frequent flyers, GigSky One’s 25% subscription discount is worth running the maths on before your next trip.

Does GigSky work on cruise ships?
Yes. GigSky is the only major eSIM provider with dedicated cruise ship plans. Coverage includes 280+ vessels across Caribbean, Mediterranean, Alaska, and Asia cruise routes. Plans are available as cruise-only or as combined cruise + land bundles for itineraries that include shore excursions.
Can I use GigSky on flights?
Yes, on select airlines. GigSky offers inflight connectivity plans for participating carriers. Note that Inflight plans are excluded from the CHAMPAGNEMILE promo code discount.
Does GigSky include calls and SMS?
No. GigSky is a data-only service. Your home carrier SIM remains active in a dual-SIM setup for calls and SMS. Data-based calling via WhatsApp, FaceTime, and similar apps works normally over the GigSky data connection.
How do I get the GigSky free trial?
Download the GigSky app (iOS or Android), create a free account, and the free data trial is added automatically – no credit card required. New users receive 500MB free in 42 European countries, or 100MB free in 125+ other destinations. The trial is valid for 7 days from activation.
Does GigSky’s unlimited plan really have no data limit?
GigSky’s unlimited plans include a 2.5GB daily high-speed cap. After you use 2.5GB in a single day, speeds throttle noticeably until the following day – enough for messaging and maps, but not for streaming or video calls. The data allowance itself is unlimited; only the speed is affected after the daily cap.
Is GigSky compatible with my phone?
GigSky works on most eSIM-compatible devices released after 2018: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer. Your phone must not be carrier-locked. The free trial is a risk-free way to confirm compatibility before buying a paid plan.
What is GigSky One?
GigSky One is GigSky’s subscription tier, providing a recurring monthly data allowance usable in 120+ countries under a single eSIM. Subscribers receive 25% off most plans including cruise plans. It’s designed for frequent travellers who make multiple international trips per year.
Can I top up my GigSky eSIM mid-trip?
Yes. Additional data plans can be purchased and applied to your existing GigSky eSIM through the app without reinstalling. This makes mid-trip top-ups seamless, particularly useful on cruise itineraries where you may want to add data for specific port days.
Is GigSky better than Airalo?
It depends what you’re doing. For cruises, GigSky wins easily since Airalo doesn’t offer dedicated ship plans. For land-only trips to budget-friendly regions like Southeast Asia, Airalo is usually cheaper per gigabyte. For Europe and North America the two are fairly close, so it comes down to whether you need cruise coverage at all.
Is GigSky legit and safe to use?
Yes. GigSky has been operating since 2010 and runs as a full Mobile Virtual Network Operator with agreements across 400+ carriers, rather than reselling someone else’s SIMs. It holds a 4.3 out of 5 rating on Trustpilot from over 3,100 reviews.
