GigSky eSIM review

3.7

The short answer. GigSky sells prepaid travel eSIM plans in 191 countries, and its cheapest rate today is $0.53 per GB. Its median rate of $4.80 per GB is about 70% above the $2.83 median across every plan we track. You are paying above the middle of the market for a typical plan here, so open the country page for your destination before you buy: it ranks every seller we track on the same maths.

Have we checked these prices?

89% of GigSky's plans on this site were checked against GigSky's own shop on 16 October 2026, one country page at a time. We confirm the product is on sale and that the price is the one they charge, and we take their price over ours whenever the two disagree.

A feed is not a shop. Feeds can list products that are not on sale, describe them differently, or carry a stale price, so a price nobody has checked again is only a number we copied.

GigSky did not pay for this review or this rating. The rating is computed from live catalogue data and cannot be bought. If you buy through a link on this page we may earn a commission, and the price you pay stays exactly the same.

About GigSky

Who is GigSky?

GigSky is one of the oldest names in travel data. Founded in 2010 in Palo Alto and still founder led, it was Apple's launch data partner for the Apple SIM on iPad back in 2015 and supported eSIM iPhones from the very start. Unlike most travel eSIM shops it manages its own eSIM core rather than purely reselling.

Its speciality is reach: around 200 countries and regions through 400 network partners, plus coverage where almost nobody else works, including more than 200 cruise ships and inflight WiFi on 20+ airlines. Visa cardholders get free data perks through the GigSky app.

The trade off is price and policy. GigSky usually sits above the budget crowd in our price per GB tables, cruise plans are notably expensive, and the refund policy is the strictest we track: plans are non refundable even if never activated.

Is there a GigSky discount code?

Not one we can vouch for right now. We only publish a GigSky promo code after testing it at GigSky's own checkout, and most codes on coupon sites are expired or never worked. If a working discount code appears it will be listed here, and it will never change where GigSky ranks in our tables.

GigSky eSIM FAQ

What people ask before they buy a GigSky eSIM, answered from live data

Is GigSky legit?

GigSky is a real seller with 945 live plans in our catalogue covering 191 countries, and every one of those prices is checked again at each catalogue refresh. 89% of those plans were checked against GigSky's own shop on 16 October 2026, so the prices here are the ones a buyer sees. Trustpilot shows 4.3 out of 5 from 6,083 reviews, collected independently of us. Our own rating of 3.7 out of 5 is computed from prices and coverage and cannot be bought.

How much does a GigSky eSIM cost?

GigSky plans run from $2.99 to $212.49. Ranked by real price per GB the best rate is 50 GB for 180 Days at $26.39, which is $0.53 per GB. Across the whole catalogue the median is $4.80 per GB against a market median of $2.83, so a typical GigSky plan is dearer than the market.

Does GigSky have a discount code?

Not one we can vouch for. We only publish GigSky promo codes that we have tested at its checkout, and there is no working code right now. Most codes on coupon sites are expired, so check the total on the payment page before you count on a discount.

Which countries does GigSky cover?

191 countries in our catalogue. The cheapest GigSky destinations by price per GB right now are Thailand ($0.53), Austria ($0.56), Belgium ($0.63). Every country in the table on this page links to its full comparison, where GigSky is ranked against every other provider we track.

Can I use a GigSky eSIM as a hotspot?

Hotspot and tethering supported.

Does GigSky sell unlimited data plans?

2 of its 945 plans are sold as unlimited. In practice they are fair use plans: full speed up to a daily allowance, then slower. That is why they carry no price per GB in our tables.

How do I install a GigSky eSIM?

App based install, QR by email also available. Plans bought and managed in the GigSky app. Buy the plan online, scan the QR code on wifi before you fly, and leave the new line switched off until you land. Then turn on data roaming for the GigSky line and give it a minute to attach to a network. If the code will not install, our guide to eSIM QR code errors covers every message a phone can show.
