Compare 4 top-rated eSIM providers as alternatives to GigSky. Find better pricing, features, and coverage.
GigSky offers 1937 plans across 187 countries, but with a modest 3.5 rating on TrustPilot, many travelers are exploring other eSIM providers that deliver better value or higher customer satisfaction. In 2025, four standout alternatives—Airalo, Saily, UBIGI, and Roamless—are worth your attention, especially if you're hunting for budget-friendly options like Roamless or top-rated service from UBIGI. Each brings its own strengths to the table, so finding the right fit depends on where you're headed and what matters most for your trip.
GigSky's massive catalog of 1,937 plans across 187 countries makes it a solid choice for travelers who want extensive options, but that breadth comes at a cost. At $2.16 per GB on average, it sits in the middle of the pack—not outrageously expensive, but not the budget pick either. The service makes the most sense for frequent travelers visiting multiple regions who value having a single provider they can stick with, or for those heading to less common destinations where coverage matters more than rock-bottom pricing.
Price-conscious travelers should take a hard look at Roamless, which consistently undercuts GigSky on cost. While specific pricing varies by destination, Roamless positions itself as the budget leader among these five providers. The trade-off? You're working with a newer player that may have fewer plan options and a smaller track record than GigSky's nearly 2,000 configurations. For straightforward trips to popular destinations, though, Roamless delivers connectivity without the premium price tag.
The real advantage GigSky holds is plan variety. Those 1,937 plans mean you can find highly specific options for unusual itineraries or longer stays, whereas competitors typically offer more streamlined catalogs. Coverage across 187 countries also means GigSky works in places where some alternatives don't operate. Travelers bouncing between multiple countries—especially mixing popular and off-the-beaten-path destinations—benefit from this flexibility rather than juggling multiple eSIM providers mid-trip.
Customer satisfaction tells an interesting story: UBIGI earns the highest ratings among these alternatives, surpassing GigSky's 3.5 TrustPilot score. That higher rating likely reflects more consistent service quality, better app performance, or more responsive customer support—the unglamorous factors that matter most when you're troubleshooting connectivity issues in an unfamiliar country. GigSky's mid-range rating suggests it gets the job done but doesn't consistently wow users the way UBIGI apparently does.
For digital nomads and business travelers who need reliable connectivity without constant price shopping, UBIGI's superior ratings justify paying attention to their offerings. Short-term tourists focused purely on cost should start with Roamless and only move up if coverage gaps appear. GigSky fits best in the middle: travelers who want proven reliability across an unusually wide range of countries and don't mind paying $0.88 per day for that peace of mind.
Airalo stands out as a compelling alternative to GigSky primarily because of its pricing advantage and strong user satisfaction. At $0.35 cheaper per day on average, Airalo delivers meaningful savings for travelers on multi-week trips or those making several short journeys throughout the year. The platform also earns a 4.0 TrustPilot rating compared to GigSky's 3.5, suggesting more consistent user experiences with connectivity and customer support. While Airalo covers 9 fewer countries than GigSky's 187 destinations, its 178-country footprint still blankets nearly every major travel route, and the service compensates with 1,260 data plans that span budget-friendly options and regional bundles unavailable from many competitors.
Budget-conscious travelers and digital nomads typically find Airalo the better fit, especially when visiting popular destinations across Europe, Asia, or Latin America where the provider's coverage shines. A two-week European trip, for instance, could save $5–7 on connectivity costs alone without sacrificing reliability. GigSky retains an advantage for travelers heading to very remote or niche destinations within that 9-country gap, and its slightly larger plan catalog may offer more granular data increments for specific trip lengths. The higher user rating, though, suggests Airalo handles the basics—activation, network stability, top-ups—more smoothly in everyday scenarios.
For most travelers, Airalo makes sense when:
GigSky remains the safer pick for truly off-the-beaten-path itineraries or travelers who prefer a brand with marginally more destination options, even at a premium.
Saily presents a compelling case for travelers seeking better value without sacrificing coverage. At $0.35 cheaper per day than GigSky, the savings add up quickly on longer trips—a two-week journey could save nearly $5 just on daily rates alone. Beyond pricing, Saily covers 8 more countries than GigSky's 187, reaching 195 destinations worldwide, while maintaining a 4.0 TrustPilot rating compared to GigSky's 3.5. The combination of lower cost, broader reach, and stronger user satisfaction makes Saily particularly attractive for budget-conscious travelers who don't want to compromise on reliability.
Where Saily really shines is for multi-destination trips across diverse regions. Travelers hopping between Southeast Asia, Europe, and Latin America benefit from both the expanded country list and the cost savings, especially on extended journeys where daily rates matter more than per-GB pricing. GigSky does maintain an advantage with its 1,937 plans compared to Saily's 816, offering more granular options for travelers with very specific data needs or those visiting niche destinations where GigSky has established partnerships. Business travelers who need predictable coverage in specific corporate hubs might prefer GigSky's deeper plan catalog.
Budget-focused backpackers and digital nomads should seriously consider Saily, especially when traveling for weeks rather than days. The higher user rating suggests fewer connection headaches, while the daily savings can fund an extra meal or hostel night. GigSky remains the better choice for travelers who value having maximum plan flexibility or who frequent specific regions where its larger plan selection provides tailored options that Saily's more streamlined catalog doesn't match.
UBIGI stands out as a compelling alternative to GigSky, particularly for travelers who prioritize cost savings and geographic reach. At $0.73 per day on average, UBIGI undercuts GigSky by $0.15 daily—a difference that adds up quickly on multi-week trips. Beyond pricing, UBIGI covers 200 countries compared to GigSky's 187, giving travelers access to 13 additional destinations. The provider also earns a 4.1 TrustPilot rating, edging ahead of GigSky's 3.5, which suggests stronger customer satisfaction overall. With 923 plans available, UBIGI offers plenty of flexibility across different data needs and trip lengths, even if GigSky's catalog of 1,937 plans is more than twice as large.
The trade-off comes down to selection versus value. GigSky's significantly larger plan library means travelers heading to niche regions or looking for highly specialized packages might find exactly what they need more easily. UBIGI, however, excels for budget-conscious travelers making frequent trips across Europe, Asia, or Latin America, where its combination of broad coverage and lower daily rates delivers measurable savings without sacrificing reliability. A backpacker spending three weeks across Southeast Asia, for example, would save over $3 on UBIGI while still enjoying dependable connectivity in major cities and rural areas alike.
For most travelers, UBIGI makes sense when:
GigSky remains the better pick when you need a very specific plan type or prefer a provider with a longer track record in a particular region.
Roamless stands out as a compelling alternative with 4,367 plans spanning 194 countries—giving travelers access to 7 more countries than GigSky's 187-destination network. Both providers share the same 3.5 TrustPilot rating, but Roamless pulls ahead with its significantly larger plan selection, offering more than double the options available through GigSky's 1,937 plans. This translates to better flexibility when matching a plan to specific trip lengths and data needs, while maintaining similar pricing to what GigSky charges per gigabyte.
The larger plan inventory proves especially valuable for travelers who bounce between regions frequently or need precise data amounts. A two-week trip across Southeast Asia, for example, benefits from Roamless's ability to offer region-specific packages tailored to exact duration and usage patterns. GigSky still holds appeal for users who prioritize a streamlined selection process—fewer choices can mean faster decision-making—but the trade-off is less granular control over what you're paying for. Roamless's broader country coverage also matters for adventurous travelers heading to less common destinations where an extra seven countries of availability could be the difference between staying connected or scrambling for local SIM cards.
For travelers who want maximum destination flexibility and appreciate having dozens of plan configurations to choose from, Roamless delivers stronger value than GigSky. The combination of wider geographic reach and a more extensive plan catalog makes it particularly suited to frequent international travelers or anyone planning multi-country itineraries where coverage gaps aren't acceptable.
After comparing GigSky with Airalo, Saily, UBIGI, and Roamless in 2025, one thing is clear: most travelers will find better value and flexibility by switching. GigSky's higher pricing and smaller network coverage make it hard to justify when these four alternatives deliver more competitive plans, broader regional options, and stronger user feedback.
Here's how to match your priorities to the right provider:
GigSky still makes sense if you already have credits invested in their platform, but starting fresh means you can take advantage of better deals and more robust service elsewhere. For most people, switching to one of these four alternatives means saving money while gaining access to networks that travelers actually recommend.
