Plan data sourced 02 Jun 2026. Plans come from GigSky and reputable aggregators (esimdb, esims.io); per-brand performance scores stay pending until independently verified.
What GigSky is
GigSky Inc. is a travel eSIM provider based in Palo Alto, California, founded in 2010 by Ravi Rishy-Maharaj. It is one of the longer-established names in the category, predating most of the travel eSIM brands Simscanner tracks. GigSky sells prepaid data across 200+ countries and destinations in three shapes , local single-country plans, regional bundles, and global plans , alongside less common cruise, ferry, and inflight options. Travellers buy and manage plans through the GigSky app (iOS and Android) or website, and the eSIM arrives in-app or by email with a QR code. Plans do not auto-renew; you choose when to top up or buy again.
What follows is a record, not a recommendation. Simscanner neither sells eSIMs nor crowns a winner; it documents GigSky against the same categories used for every brand. The corporate basics here come straight from GigSky's pages, while the plan figures throughout are sourced from GigSky and reputable aggregators (esimdb, esims.io), each carrying a 02 Jun 2026 retrieved date. Speed, reliability, and review scores stay pending: they cannot be cleanly attributed per country, and an estimate is never substituted for a sourced number.
Countries tracked
GigSky appears on 71 Simscanner-published country pages, each linking to that destination's full comparison. The figure counts only Simscanner pages, not GigSky's own catalogue, which the brand states reaches 200+ countries and destinations.
Where GigSky plans are sourced
SecondaryTracked destinations span every populated region. Examples with sourced GigSky plans include the United States (1GB/7d $4.49), the United Kingdom (1GB/7d $5.99), Japan (1GB/7d $6.99), Mexico on Telcel (1GB/7d $6.99), and Switzerland with an unlimited/30d plan at $91.99 (2.5 GB/day high-speed). Prices are USD as listed by the source on 02 Jun 2026.

Regions tracked
Simscanner tracks eight canonical regions. Sourced GigSky plans appear in seven of them , Europe, Asia (including the Middle East), North America, South America, Oceania, Africa, and global "World" plans. The Caribbean reads as pending, as no GigSky plan is sourced on a Caribbean country page yet.
Coverage
How clearly a brand publishes the country list for each plan , and how Simscanner checks it.
For coverage, the question Simscanner asks is simple: does GigSky tell you, on the plan page itself, exactly which countries a plan works in before you buy? GigSky does , it runs dedicated per-country pages plus named regional and global plan lists, so a destination can be checked rather than assumed. Simscanner records that list from the source and re-checks it on a schedule, instead of echoing a headline "200+ destinations" figure as if it were verified per plan.
GigSky states coverage of 200+ countries and destinations, sold as local, regional, global, and travel-specific (cruise, ferry, inflight) plans. Simscanner counts 71 of those destinations on its own published country pages, where each GigSky plan is sourced individually rather than inferred from the brand's headline figure. For how breadth is weighed across brands, see which eSIM has the best coverage.
Country list published per plan
GigSky publishes per-country plan pages and regional/global plan lists on its own site.
PublishedRe-verification cadence
Coverage is re-checked at least every 90 days once verified.
PendingLocal network transparency
Which local carrier a brand connects to in each country shapes real-world speed and reliability. Simscanner maps this country by country from sourced data , never from assumption.
Network mapping pending
PendingLocal-network mappings for GigSky are confirmed on each country page, not asserted at the brand level. Simscanner publishes which network a brand uses in a country only when that mapping is sourced and verified for that specific country.
Unlimited and fair use policy
Whether a brand markets "unlimited" plans, and whether it publishes a fair use policy (FUP) threshold, is one of Simscanner's tracked categories. Thresholds are only ever shown as a sourced quote , never estimated.
GigSky , unlimited & FUP
FUP sourcedGigSky does market unlimited plans, and they carry a published fair use policy. On the unlimited country plans Simscanner sourced, a daily high-speed allowance applies, after which speed is throttled for the rest of that day before resetting. The threshold most commonly seen across tracked plans (for example Croatia, Iceland, Kazakhstan, and Switzerland) is 2.5 GB/day; GigSky markets allowances up to 3.5 GB/day on some of its plans. The figure varies by plan, so always confirm it on the specific plan page before relying on it.
As sourced from GigSky's unlimited data page (retrieved 02 Jun 2026): unlimited plans provide high-speed data up to a daily allowance, after which data is throttled for the remainder of that day.

Hotspot tethering
Hotspot (tethering) support varies by brand and sometimes by plan. Simscanner states a brand's policy only from its own published wording, with the date retrieved.
Some travellers depend on tethering , sharing the eSIM connection with a laptop, tablet, or a travel companion's phone. Because policies differ and occasionally change by plan, Simscanner does not infer hotspot support; it records the brand's stated allowance verbatim, with a retrieved date, once verified.
GigSky states that hotspot data sharing is permitted to any device on its unlimited plans, so tethering a laptop or a companion's phone is allowed rather than blocked. Hotspot use draws from the same daily high-speed allowance, so heavy tethering can reach the FUP threshold sooner. For how this category is weighed, see hotspot with a travel eSIM.
Hotspot allowed?
Yes , GigSky permits hotspot data sharing to any device on unlimited plans.

SourcedDevice compatibility & activation
The general requirements that apply to any travel eSIM. Brand- or model-specific details are only listed once sourced.
Like all eSIMs, a GigSky plan needs a device that is both eSIM-capable and carrier-unlocked. After purchase, GigSky delivers the eSIM through its app or by email with a QR code, so a plan is typically installed before departure and switched on after arrival. These are the activation mechanics GigSky publishes, not claims about specific phone models.
Simscanner does not publish a supported-device list it has not sourced. A confirmed model-by-model compatibility summary for GigSky will appear here once verified against the brand's own documentation.

PendingSpeed & reliability signals
Performance depends on the local network a brand rides on in each country, so Simscanner reports it country by country from public performance data , not as a single brand-wide figure.
Speed data pending
PendingBecause a brand's real-world speed reflects the local carrier it connects to, Simscanner does not publish a global speed score for GigSky. Sourced speed and reliability signals appear on the relevant country pages once verified for that destination.
Reviews & user sentiment
A summary of signal, not an editorial verdict. Simscanner never invents ratings and never republishes a number without a primary source.
Independent review signals for GigSky are pending. Simscanner does not republish App Store, Play Store, or third-party ratings without a primary source. When sourced, each rating is shown with its review count and the date it was fetched , never as a Simscanner score, and never emitted as rating schema.
What is sourced, and what is pending
An honest ledger of each tracked field. Plan, coverage, FUP, hotspot, and KYC fields are now sourced (marked below); per-brand speed, reliability, and review scores stay pending. GigSky is not penalised for a pending field , it simply isn't ranked on it until that field is independently sourced.
Compared with peers
GigSky is most usefully compared with other global travel eSIMs , Airalo, Holafly, and Nomad , across the categories Simscanner tracks. Each verified head-to-head publishes once GigSky and the peer both reach the data gate. Until then, the comparison reads pending.
