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.
For frequent travellers, GigSky One (the annual subscription tier) delivers 25% off most plans ongoing -more than the promo code alone. If you travel three or more times a year, the maths heavily favour the subscription.
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.
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.
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.
