Yesim vs GigSky: Which Travel eSIM Is Better?
Yesim and GigSky are both travel eSIM providers that give your phone mobile data abroad without a physical SIM card. They overlap a lot — destination, regional, and global data plans managed in an app — but differ in maturity, plan flexibility, refund terms, and specialty coverage. The better choice depends on your destinations, trip length, data needs, hotspot use, and budget, and eSIM plan details change often. We compare providers using public plan information — not hands-on testing.

Best for flexible, app-first plans

App-first with destination, regional, and global plans plus a pay-as-you-go option, and a clearer 30-day refund for unused plans.

GigSky
A long-standing provider (since 2010) with broad coverage and unusual cruise, ferry, and in-flight options, plus a free trial.
What is Yesim?
Yesim is a travel eSIM provider that works like a connectivity aggregator, reselling data across partner networks worldwide on a single eSIM you can reuse across trips. It markets coverage across 200+ destinations (a figure to treat as approximate) and organizes plans into local, regional, and global tiers.
Most Yesim plans are fixed-data packages, with some unlimited options on popular destinations and a flexible pay-as-you-go option. It's app-first, with a promoted one-click installation. If you're also weighing two of the most popular eSIM brands, see our Saily vs Airalo comparison.
What is GigSky?
GigSky is an established travel eSIM provider that operates as a mobile network operator (MVNO) rather than a simple reseller. Founded in 2010 and based in California, it offers data-only plans — single-country, regional, and global — plus specialty connectivity for cruises, ferries, offshore, and in-flight, and a recurring GigSky One subscription.
Its plans are mostly fixed-data, with some unlimited options on select destinations, and the eSIM is reusable across trips. GigSky's standout is breadth and niche coverage; its trade-off is a stricter refund policy (more below). For another marketplace-style matchup, see our Airalo vs Holafly comparison.
Pricing style: which one is better value?
There is no universal "cheaper" winner. Both Yesim and GigSky can run higher than budget-focused eSIMs, and the better value depends on your destination, the data amount, and any current promotions. GigSky offers a free trial so you can test coverage before paying, while Yesim's pay-as-you-go option can suit unpredictable usage.
Compare like-for-like — the same destination, a similar data amount, and a validity period that covers your trip — and check the current price on each provider's site rather than assuming one is always cheaper.
Data options and trip length
Both providers sell mostly fixed-data packages, with some unlimited options on select destinations that are typically subject to fair-use or daily high-speed limits. The key is matching the data amount and validity period to your trip.
Estimate your daily usage — maps and messaging use little, while streaming, video calls, and hotspot use add up quickly — then choose a plan with some headroom. For longer trips, confirm the validity period covers your full stay. Varies by destination and plan — check current details before purchase.
Coverage and destination availability
Both providers market broad worldwide coverage — each advertises 200+ destinations (treat the exact numbers as approximate) — but the only figure that matters is whether your specific destination is supported with a plan that fits. GigSky additionally markets unusual coverage for cruises, ferries, and in-flight, which can matter for sea or air travel.
Always confirm your exact country or region on the provider's site. If you're focused on a single country, a destination guide can help — see our best eSIM for Spain comparison as an example.
Regional and global plans
Both Yesim and GigSky offer regional and global plans alongside single-country options. Yesim provides multiple regional packages plus several global tiers and a pay-as-you-go option, while GigSky offers regional plans, world plans, and the recurring GigSky One subscription for travelers who are abroad often.
For a trip that crosses several countries, a regional plan is usually more convenient and cost-effective than buying separate single-country plans — just confirm that every country on your itinerary is included. Varies by destination and plan — check current details before purchase.
Hotspot and tethering
Both providers generally allow hotspot and tethering on their eSIM plans, with shared data counting against your allowance. Yesim states that tethering is enabled by default on most plans, but notes that real-world availability depends on the local network operator. GigSky allows tethering on its eSIM plans, though it can depend on the plan, device, and network.
If sharing your connection with a laptop or other devices matters to you, verify the current tethering rule for the exact plan before purchasing — this is one of the most plan-specific details for any eSIM. Varies by destination and plan — check current details before purchase.
Refund policy and purchase protection
Refund terms are a meaningful difference here. Yesim's published policy offers refunds for unused plans and top-ups within 30 days of purchase; used or expired plans are not refundable, and small refunds (10 EUR or less) are issued as non-refundable "Ycoins" store credit.
GigSky's consumer terms are more restrictive: once sold, the SIM and any top-up generally cannot be returned and unused usage is not refunded, regardless of activation, with only a narrow exception for a minimally used subscription plan affected by a service issue. With either provider, read the current refund policy before buying and avoid activating a plan until you're sure you can use it.
Setup and app experience
Setup is straightforward for both on a modern, eSIM-compatible, carrier-unlocked phone. Yesim is app-first with a promoted one-click installation (QR-code and manual options are available on some devices). GigSky is also app-based; you install via the app or a QR code, and the plan typically activates when the eSIM first connects at your destination.
GigSky's free trial lets you test coverage before paying. Whichever you choose, install while you still have a reliable internet connection and confirm your device supports eSIM beforehand. Public reviews are generally positive for both, with occasional notes about connectivity in certain regions and support response times — which is why confirming current terms matters.
Which is better for short trips?
For a short, light trip, a small fixed-data plan from either provider is usually the most economical because you only pay for the data you expect to use. Estimate your usage — mostly maps and messaging points toward a small package — and compare the current price for your destination.
Both make short-trip purchases easy, so the deciding factor is often simply which has the better-priced small plan for your country.
Which is better for longer trips?
For longer trips, the deciding factors are validity and total data. GigSky's world plans and GigSky One subscription can suit extended or frequent travel, while Yesim's larger plans, global tiers, and pay-as-you-go option offer flexibility.
Either can work — confirm the validity period covers your entire stay, and for multi-country trips compare a regional plan against separate single-country plans. Varies by destination and plan — check current details before purchase.
Which is better for budget travelers?
For budget travelers, there's no single cheaper provider — both can run higher than budget-focused rivals, and the lowest cost depends on your destination and data needs. GigSky's free trial can help you confirm coverage works before you commit, which avoids wasted spend.
Compare the same destination and a similar data amount on each provider, and factor in validity so you don't pay for days or data you won't use. Pricing and availability may change by destination.
Which is better for first-time eSIM users?
Both are app-based and beginner-friendly. Yesim promotes a one-click installation and a 30-day refund for unused plans, which can be reassuring for a first purchase. GigSky offers a free trial so you can test coverage before paying — also helpful if it's your first eSIM.
For any first-time user, the most important steps are the same: confirm your phone is eSIM-compatible and carrier-unlocked, install before you travel, and keep your existing connection until the eSIM is working.

Both generally allow hotspot and tethering on their eSIM plans, with shared data counting against your allowance. Yesim states tethering is enabled by default on most plans but that availability depends on the local network operator; GigSky allows it on eSIM plans, though it can depend on the plan, device, and network. Verify the current rule for your specific plan before relying on it.

Both Yesim and GigSky offer Europe regional plans that span many countries, so the better pick depends on coverage for the countries you are visiting and the current price. Confirm coverage for your itinerary and compare current European plans before buying.
