Compare 4 top-rated eSIM providers as alternatives to Saily. Find better pricing, features, and coverage.
Saily covers 195 countries and earns solid reviews, but with only 816 plans to choose from, travelers often find better pricing or more flexible options elsewhere. We've compared four strong alternatives in 2025—Airalo, UBIGI, Roamless, and simOptions—that bring sharper rates, higher ratings, or both to the table. Roamless stands out for budget-conscious users, while simOptions leads the pack in customer satisfaction.
Saily sits comfortably in the middle of the eSIM market with 816 plans across 195 countries and a respectable 4.0 TrustPilot rating. It's not the cheapest option available, nor does it lead in customer satisfaction scores. But that middle ground makes sense for travelers who want solid worldwide coverage without paying premium prices—especially when visiting multiple destinations on a single trip. The sheer number of plans means you'll likely find something suitable whether you're heading to Tokyo, Reykjavik, or Buenos Aires.
Roamless takes the crown as the cheapest alternative, which matters when you're watching your travel budget closely. The price difference becomes meaningful over longer trips or if you're burning through data while navigating unfamiliar cities. What you might sacrifice for those savings typically comes down to plan variety and network partnerships—fewer options can mean less flexibility to fine-tune your data package to match your exact travel dates. Saily's 816 plans versus whatever Roamless offers gives you more room to avoid overpaying for unused data or running out mid-trip.
Coverage becomes critical when your itinerary spans multiple countries. Saily's 195-country footprint handles most travel scenarios, from popular European capitals to less-traveled Southeast Asian destinations. The daily rate of $0.53 sits at a reasonable point for casual data use—checking maps, staying in touch, posting the occasional photo. Compare that to the $2.33 per GB average, and you'll want to calculate whether unlimited daily plans or pay-per-gigabyte options work better for your usage patterns.
simOptions earns the highest customer rating among these providers, which usually signals something's working well beyond just competitive pricing. Top ratings in the eSIM space typically reflect smooth app experiences, reliable connections that don't drop when you need directions most, and responsive support when activation hiccups occur. That customer satisfaction premium matters more than spreadsheet comparisons suggest—there's real value in an eSIM that connects immediately after landing instead of leaving you troubleshooting in an airport terminal.
Budget-conscious backpackers bouncing between hostels will gravitate toward Roamless despite potential limitations. Business travelers who need guaranteed connectivity across multiple countries get better value from Saily's extensive plan catalog and solid track record. Those willing to pay slightly more for proven reliability and superior customer service should examine simOptions closely, particularly for trips where connectivity failures would cause serious problems.
Airalo stands out as a seasoned alternative to Saily, particularly for travelers who value plan flexibility. With 1,260 plans compared to Saily's 816, Airalo gives you significantly more options to match your specific trip length and data needs. Both services share identical TrustPilot ratings of 4.0 and cost the same $0.53 per day on average, so the choice comes down to breadth of choice rather than price or reputation. The one area where Saily pulls ahead is geographic reach—it covers 195 countries versus Airalo's 178, meaning travelers heading to more remote or emerging destinations might find Saily has coverage where Airalo doesn't.
For multi-country trips across Europe, Asia, or Latin America, Airalo's extensive plan variety becomes a real advantage. A traveler spending three weeks hopping between Thailand, Vietnam, and Cambodia can often find regional bundles tailored to Southeast Asia, rather than buying separate country plans or overpaying for a global package. The trade-off is that Saily's slightly broader footprint makes it the safer bet for less-traveled routes—think Pacific islands or parts of Central Africa—where Airalo's network partnerships don't extend. Both providers deliver reliable connectivity at the same daily cost, but Airalo rewards travelers who prefer customizing their coverage rather than relying on one-size-fits-all options.
Choose Airalo when plan selection matters more than absolute global coverage. Budget-conscious travelers visiting popular destinations will appreciate the ability to fine-tune data allowances without sacrificing quality or paying a premium.
UBIGI deserves attention as a Saily alternative because it covers 200 countries compared to Saily's 195, and offers 923 plans versus Saily's 816—giving travelers more flexibility to find exactly the right fit. The TrustPilot ratings are nearly identical (4.1 for UBIGI, 4.0 for Saily), which suggests comparable reliability in real-world use. UBIGI does cost $0.20 more per day on average, but that extra expense often buys access to a broader catalog of regional and multi-country plans that can simplify trip planning across several destinations. The sheer number of plan options means travelers can often find better value for specific regions, even if the headline average is slightly higher.
UBIGI shines for multi-country European trips and frequent travelers who need reliable service across a wide range of destinations without constantly switching providers. The combination of 200-country coverage and nearly a thousand plans means you're more likely to find a regional bundle that beats buying separate country-specific eSIMs—something particularly useful for backpackers or business travelers hitting four or five countries in a single journey. Saily may still appeal to travelers prioritizing the lowest possible daily rate or those who prefer a more streamlined, curated selection of plans, but UBIGI's variety reduces the friction of planning complex itineraries.
For travelers who value choice and comprehensive global reach, UBIGI makes sense despite the modest price premium. It's the stronger pick when visiting less common destinations or when you need the reassurance of knowing your provider has multiple plan tiers in each region. Saily remains competitive for single-country trips or short stays where simplicity and slightly lower cost matter most.
Roamless stands out with 4,367 available plans—more than five times Saily's 816 options—giving travelers significantly more flexibility to match data packages to their specific trip needs. Coverage is nearly identical at 194 countries versus Saily's 195, and pricing remains competitive between the two providers. The Trustpilot rating of 3.5 sits half a point below Saily's 4.0, suggesting a solid but not exceptional user experience. What travelers gain with Roamless is sheer variety: whether you need a tiny data package for a weekend city break or a month-long plan across multiple regions, the massive plan library means you're far more likely to find an exact-fit option rather than overpaying for unused gigabytes.
For travelers who hop between destinations frequently or need very specific data amounts, Roamless delivers real value through its extensive plan selection. Someone spending three weeks across Southeast Asia, for example, can often piece together country-specific or regional plans that cost less than a single global package. The trade-off comes in user confidence: Saily's slightly higher rating suggests fewer customer service headaches or connectivity issues, which matters when you're troubleshooting in an unfamiliar country. Roamless works best for travelers comfortable comparing multiple options and prioritizing cost savings over a marginally smoother experience.
Choose Roamless when you want maximum control over your eSIM purchase and don't mind spending a few extra minutes comparing plans. Stick with Saily when you'd rather pay a small premium for the peace of mind that comes with a higher user rating and simpler decision-making. The price difference between them is minimal, so the real question is whether you value plan variety or proven reliability more on your next trip.
simOptions stands out as a compelling alternative with 199 countries covered—4 more than Saily's 195—and a 4.3 TrustPilot rating that edges past Saily's 4.0. The daily cost averages $0.50, shaving a few cents off Saily's $0.53, while the cost per gigabyte remains in the same ballpark. More importantly, simOptions offers 1,111 plans compared to Saily's 816, giving travelers substantially more flexibility when hunting for a data package that matches their exact trip length and data needs. That variety matters when you're bouncing between a weekend city break and a month-long backpacking route.
The broader plan catalog really shines for anyone making repeat trips to different regions or needing unusual data increments. A traveler heading to Southeast Asia for three weeks, then Europe a month later, can find region-specific options without settling for a one-size-fits-all global plan that wastes unused data. Saily still has the edge in brand recognition and a slightly more streamlined app experience, so first-time eSIM users who value simplicity over choice might prefer its narrower, curated selection. But for budget-conscious travelers who don't mind spending five extra minutes comparing plans, simOptions delivers better coverage, a stronger user rating, and more ways to fine-tune costs without sacrificing reliability.
After comparing Saily with Airalo, UBIGI, Roamless, and simOptions, the landscape is clear: each provider serves distinct traveler needs, and most users will find a better match by shopping around. While Saily offers solid coverage, the four alternatives reviewed here deliver stronger value in specific areas that matter most to different types of travelers.
Your best choice depends on what you prioritize:
For most travelers in 2025, sticking with Saily means leaving money on the table or settling for fewer user protections. Spending ten minutes comparing plans from these four alternatives typically saves 20–40% per trip while improving your odds of a smooth connection abroad.
