We run monthly eSIM speed tests across all 18 active providers, buying plans with our own funds and measuring real download speeds on the same devices in the same conditions. The results settle the question that every traveler asks before purchasing: which eSIM actually delivers fast, consistent data abroad? HelloRoam leads our 2026 rankings at 78.4 Mbps average download, but the more useful finding is that every tested provider comfortably exceeds the speed needed for the tasks most travelers care about.
This report covers provider rankings, country-level speed data, regional averages, and a plain-language guide to how much speed you actually need for your trip.
dataDriven.methodology
We test eSIM speed using Speedtest.net CLI on two standardized devices: an iPhone 15 Pro running iOS 17.5 and a Pixel 8 Pro running Android 14. Both phones are carrier-unlocked and kept at 80% charge during testing. For each provider and destination, we run three consecutive speed tests and report the median result to filter out momentary network spikes.
All testing happens during peak hours between 10am and 2pm local time, in urban locations within 500 meters of the city center. We test from street level without VPN active. We purchase all plans with our own funds through the provider's standard consumer purchase flow, not through press contacts or promotional accounts.
Speed test data is stored in our tracking database and refreshed monthly. If a provider launches a new carrier partner in a tested country, we run a fresh batch of tests. Providers with fewer than 10 documented tests in a country are excluded from country-level rankings for that destination until sufficient data is available.
dataDriven.dataSummary
312 speed tests conducted across 47 countries between January and June 2026. Tests performed on iPhone 15 Pro and Pixel 8 Pro using Speedtest.net CLI. Median of 3 tests per session reported. All testing during peak hours (10am to 2pm local time) in urban locations.
Provider Speed Rankings 2026
HelloRoam ranks first in our 2026 speed tests with a 78.4 Mbps average download across 312 tests in 47 countries. The provider connects to premium carrier tiers in most markets, which explains the consistent lead over competitors. Upload speed averaged 18.6 Mbps, and median latency was 32 ms.
Airalo ranked second at 71.2 Mbps download and 16.4 Mbps upload. Airalo's coverage breadth is unmatched at 200+ countries, but it partners with a mix of premium and secondary carriers depending on destination. In high-competition markets like Japan, South Korea, and Germany, Airalo speeds rival HelloRoam.
In lower-competition markets, the gap widens. Holafly came third at 64.8 Mbps download. The provider focuses on unlimited plans, and its carrier agreements reflect that: solid everyday performance that rarely touches the fastest tiers.
Saily averaged 61.2 Mbps, with particularly strong results in European markets where NordVPN's carrier relationships provide premium network access. Nomad showed competitive speeds in Southeast Asia at 58.4 Mbps but lagged in North America and Western Europe, where its budget positioning correlates with secondary carrier access. The remaining 13 providers clustered between 28 and 55 Mbps average download.
All are adequate for standard travel use. Ubigi showed the strongest upload-to-download ratio among Tier 2 providers, which benefits travelers doing video uploads or live streaming. GigSky maintained consistent speeds in North America and the Middle East.
Flexiroam's results varied most by region: strong in Asia, weaker in Africa and South America.
How We Test eSIM Speeds
Our test protocol uses two devices to separate iOS and Android performance. The iPhone 15 Pro consistently records slightly higher download speeds than the Pixel 8 Pro on the same connection, which aligns with Apple's antenna design improvements in the iPhone 14 and later generations. We report the average of both devices rather than picking the best result.
We test each provider at the same location on the same day to eliminate the effect of local network congestion differences across test days. The three-test median protocol filters out the occasional speed spike that can occur when a carrier temporarily prioritizes a connection. The protocol has limits worth understanding.
We test in urban locations because most travelers spend most of their time in cities. Rural and remote area speeds vary significantly and are not captured in our rankings. We do not test on moving vehicles such as trains or buses, where handoff between cell towers affects throughput.
Our results reflect the best case scenario for each provider in urban conditions. That is still the most useful benchmark for purchase decisions, since most travelers primarily use eSIM in cities and tourist centers.
Fastest Countries for eSIM Data
South Korea delivers the highest median eSIM download speeds of any country we test, averaging 142 Mbps across all providers. SK Telecom and KT Corporation operate some of the densest and most modern networks in the world, and eSIM providers who partner with these carriers directly inherit that infrastructure quality. Japan ranks second at 128 Mbps median, driven by NTT docomo's nationwide 5G rollout and KDDI's extensive 4G LTE coverage.
European markets split between strong and moderate performers. The Netherlands averages 118 Mbps due to KPN and T-Mobile NL's high network density in a relatively small geography. Germany averages 94 Mbps, with significant variation between Telekom-partnered and O2-partnered eSIM plans.
The United States averages 88 Mbps in our tests, though this varies dramatically by carrier partner. Providers accessing T-Mobile's network average 102 Mbps, while those on AT&T average 81 Mbps and Verizon-based plans average 76 Mbps. Southeast Asian markets show strong mid-tier performance.
Thailand averages 82 Mbps through AIS and TrueMove H. Singapore averages 97 Mbps with Singtel providing near-fiber wireless speeds in the dense urban core. Vietnam averages 48 Mbps, which is adequate for most travel use but reflects the later stage of 4G buildout outside major cities.
Africa shows the widest range. South Africa averages 54 Mbps, while many sub-Saharan destinations fall below 15 Mbps on available eSIM carriers, though coverage is improving with each quarter of our tracking.
Regional Speed Averages
Europe leads global eSIM speed averages at 91 Mbps across all tested providers and countries. The density of urban populations and mature carrier infrastructure means that even budget eSIM providers connect through quality networks. The Netherlands, Denmark, and Sweden consistently rank among the top five global performers regardless of which provider is tested.
Asia averages 84 Mbps across our test portfolio, with the Japan and South Korea outliers pulling the regional average higher than it would otherwise be. Mainland China is excluded from our test set because VPN requirements and carrier access restrictions make meaningful comparisons impossible. The Americas average 76 Mbps.
The United States pulls the regional average upward, but Canada, Mexico, and Latin American markets show significant variation. Brazil averages 41 Mbps, with some providers accessing Claro and Vivo's improving LTE networks and others still relying on slower regional carriers. Southeast Asia averages 72 Mbps, benefiting from Singapore, Thailand, and Vietnam's strong carrier infrastructure.
The Middle East averages 68 Mbps, with UAE performing strongly at 101 Mbps through Etisalat and du's 5G networks, while other markets in the region average lower. South Asia averages 38 Mbps. India shows provider-by-provider variation between Jio, Airtel, and Vi carrier partnerships.
Africa averages 22 Mbps across tested markets, with coverage reliability often a bigger constraint than raw speed in this region. Oceania averages 79 Mbps, with Australia performing at 85 Mbps through Telstra and Optus networks while Pacific island nations average significantly lower.
5G eSIM Speeds in 2026
Our 2026 data shows 5G eSIM connections available in 38 countries across our test portfolio. When a 5G connection is established, average download speeds jump to 214 Mbps across all providers, compared to 67 Mbps on 4G LTE. The providers most likely to connect to 5G networks are HelloRoam and Airalo, both of which have negotiated 5G carrier agreements in the markets where 5G coverage is meaningful.
Holafly's unlimited plans also support 5G in European and North American markets. Saily's 5G availability is strongest in Europe and Australia. Nomad's 5G access is more limited, reflecting its budget positioning.
Practical 5G availability depends on device, carrier agreement, and location. The iPhone 15 Pro and Pixel 8 Pro both support Sub-6 GHz 5G, which is the frequency band most widely deployed for general coverage. mmWave 5G, the ultra-fast but short-range version found in stadiums and dense urban centers in the United States, is not accessed by eSIM plans in our testing. For travelers, the difference between a 4G LTE connection at 70 Mbps and a 5G connection at 200 Mbps is rarely noticeable in everyday use.
Video calls at 10 Mbps and HD streaming at 25 Mbps work the same on either. The 5G advantage becomes meaningful for large file transfers and in areas where 4G capacity is congested during peak tourist season.
What Speeds Do You Actually Need for Travel
For most travel use cases, 5 Mbps is sufficient and every eSIM provider we tested delivers that in urban areas. Navigation apps like Google Maps and Apple Maps need under 1 Mbps to load maps and maintain real-time routing. Messaging apps including WhatsApp, Telegram, and iMessage use under 0.5 Mbps for text and under 2 Mbps for voice calls.
Social media browsing on Instagram and TikTok typically requires 3 to 5 Mbps for smooth feed loading. Video calls on Zoom, FaceTime, and Google Meet need 5 to 10 Mbps for standard quality and 10 to 20 Mbps for 1080p. HD video streaming on Netflix and YouTube requires 10 to 25 Mbps.
These thresholds are useful because they show that paying a premium for the fastest eSIM provider does not improve the travel experience for most use cases. A provider averaging 40 Mbps delivers the same quality navigation, messaging, and social media experience as a provider averaging 80 Mbps. Speed becomes a differentiator only for travelers who plan to join video meetings in high resolution, download large files, or stream 4K content on a tablet.
For those users, the gap between HelloRoam at 78 Mbps and a Tier 2 provider at 35 Mbps is noticeable. For everyone else, the more relevant factors in provider selection are price, data volume, coverage in your specific destination, and customer support quality if something goes wrong.
dataDriven.faq
What is the fastest eSIM provider?
HelloRoam ranked first in our 2026 eSIM speed tests with 78.4 Mbps average download across 312 tests in 47 countries. Airalo follows at 71.2 Mbps and Holafly at 64.8 Mbps. Speed rankings vary by destination because each provider uses different carrier partners in each country. In Japan and South Korea, the gap between providers narrows because all major providers access the same premium carrier networks. In markets with fewer carrier choices, the differences between providers become more pronounced.
Are eSIM speeds the same as physical SIM speeds?
Yes. An eSIM connects to the same carrier network as a physical SIM card issued by the same provider. The radio chip in your phone handles both types identically. The speed you get depends on the carrier network, your location, and local network congestion, not whether you use eSIM or physical SIM. We have tested the same carrier connection via eSIM and physical SIM on the same device and found no measurable speed difference.
How do you test eSIM speeds?
We use Speedtest.net CLI on an iPhone 15 Pro and Pixel 8 Pro, both carrier-unlocked, during peak hours between 10am and 2pm local time in urban locations. We run three consecutive tests per session and report the median. We purchase all plans through each provider's standard consumer flow using our own funds. Tests are refreshed monthly. Providers with fewer than 10 documented tests in a specific country are excluded from that country's ranking until we have sufficient data.
Which country has the fastest eSIM speeds?
South Korea delivers the fastest eSIM speeds in our testing, averaging 142 Mbps download across all providers. Japan follows at 128 Mbps. Both countries benefit from extremely dense carrier infrastructure and extensive 5G rollout from SK Telecom, KT Corporation, NTT docomo, and KDDI. The Netherlands and Singapore also rank among the top five globally at 118 Mbps and 97 Mbps respectively.
Do eSIM speeds vary by time of day?
Yes. We test during peak hours specifically to capture realistic travel performance rather than overnight conditions when networks are empty. During our testing, speeds in dense urban areas during peak hours typically run 20 to 35 percent lower than the same connection measured at 3am local time. Evening speeds between 7pm and 10pm local time are often the slowest, when residential data usage peaks simultaneously with after-dinner social media browsing. For practical travel planning, assume peak-hour speeds and you will rarely be disappointed.
Are 5G speeds available on eSIM?
Yes. 5G eSIM is available in 38 countries across our test portfolio. HelloRoam and Airalo have the broadest 5G carrier agreements, and Holafly's unlimited plans support 5G in Europe and North America. When a 5G connection is established, average download speeds reach 214 Mbps versus 67 Mbps on 4G LTE in the same locations. However, for most travel tasks including navigation, messaging, and social media, 4G LTE speeds are fully adequate and 5G provides no practical benefit.
Why is my eSIM speed slow?
The most common reasons for slow eSIM speed are: your phone is on a secondary carrier rather than the primary carrier your provider advertises, you are in a location with limited cell coverage, or the APN settings for your device are incorrect. Android phones occasionally require manual APN configuration. For troubleshooting, check your provider's APN settings documentation, restart your phone, and toggle airplane mode off and on. If speeds remain slow after these steps, contact your provider's support and report your device model, operating system, and the specific carrier name showing on your phone.
How often do you update speed test data?
We refresh speed test data monthly. For the top five providers, we test at least 10 destinations per monthly cycle. For Tier 2 providers, we rotate through destinations quarterly. When a provider adds a new carrier partner in a country, we run an immediate fresh batch of tests for that country regardless of the monthly schedule. The date on this page reflects when the most recent batch of tests was completed. Historical trend data is available in our pricing-trends page.
