8 Best eSIM Providers Compared 2026 (Tested Head-to-Head)

Choosing the right eSIM provider can make or break your travel connectivity. Maybe you need unlimited data for remote work and capped plans don’t cut it. Maybe you want the cheapest possible eSIM without compromising quality. Or maybe you want a built-in VPN, a pay-as-you-go model, or simply the easiest onboarding experience.

We’ve tested 8 eSIM providers across 15+ countries over the past 6 months, running 200+ speed tests and comparing pricing, features, and real-world reliability. Every provider on this list is one we’ve personally used while traveling — no spec-sheet reviews here.

Here’s the quick version: Holafly is the best choice if you need unlimited data. Saily wins on price. Nomad eSIM is the easiest entry point for first-timers. Read on for the full breakdown.

Quick Comparison: All 8 Providers

Before we dive into individual reviews, here’s how all 8 providers stack up against each other.

Now let’s break down each provider in detail.

1. Holafly — Best for Unlimited Data

Our pick if you need unlimited data without usage anxiety.

If your #1 priority is never worrying about data caps, Holafly is the clear choice. It’s the only major eSIM provider that offers genuinely unlimited data — no hard caps, no surprise throttling under normal usage. We used 40-80GB per month during our 4-month testing period and never hit a wall.

What Makes Holafly Stand Out

Where most providers charge per gigabyte, Holafly charges per day. You buy a duration (5 days, 10 days, 15 days, or 30 days) and get unlimited data for that entire period. It’s a fundamentally different pricing model that favors heavy data users.

During our testing across Thailand, Japan, Mexico, Spain, and Indonesia, we averaged 30-90 Mbps download speeds in urban areas. That’s competitive with any provider on this list, and the unlimited data more than compensates for any minor speed differences.

Pricing

• Thailand: Unlimited/5 days for $27, 10 days for $47, 30 days for $87
• Japan: Unlimited/5 days for $19, 10 days for $34, 30 days for $69
• Europe: Unlimited/5 days for $27, 10 days for $47, 30 days for $87
• USA: Unlimited/5 days for $27, 10 days for $47, 30 days for $84

Value assessment: For light users (under 5GB per trip), capped plans from Saily or Nomad are significantly cheaper. But if you use 10GB+ per trip, the math shifts. A capped 10GB/30-day plan for Thailand costs $23-28 depending on provider — and if you burn through that, top-ups at a premium rate add up fast. Holafly’s 30-day unlimited plan at $87 gives you peace of mind and unlimited data for remote work, streaming, and video calls.

Key Features

• Unlimited data — no caps, no rationing
• 180+ country coverage — covers all major travel destinations
• 24/7 WhatsApp support — fastest support response times we tested (under 3 minutes on average)
• Data sharing — share your connection with other devices via hotspot (some plans)
• Easy setup — QR code installation, 4-6 minutes from purchase to connectivity

Who Should Choose Holafly

Holafly is the better choice if you’re a remote worker running daily video calls, a content creator uploading large files on the road, or simply someone who doesn’t want to think about data limits. If you’ve ever rationed data mid-trip or been caught in a Zoom call when your plan ran out, Holafly eliminates that stress entirely.

Not ideal for: Budget travelers who use under 5GB per trip (you’ll overpay), travelers heading to destinations outside Holafly’s 180-country footprint, or anyone who prefers per-gigabyte pricing.

2. Saily — Best Value (by NordVPN)

Our pick if you want quality coverage at the lowest price.

Saily is built by Nord Security — the same team behind NordVPN — and it shows. The app is clean, the speeds are strong, and the pricing undercuts most competitors by 10-20% across most destinations. If your primary concern is value for money, Saily is the one to beat.

What Makes Saily Stand Out

Saily doesn’t reinvent the wheel. It offers the standard capped-data, per-gigabyte model — but at consistently lower prices. The NordVPN team leveraged their existing infrastructure and carrier relationships to deliver competitive rates from day one.

We tested Saily across 6 countries and averaged 40-110 Mbps download speeds, often matching or exceeding competitors at the same locations. In Japan on 5G, we hit peaks of 180 Mbps.

Pricing

• Thailand: 1GB/7 days for $3.99, 3GB/30 days for $9.99, 10GB/30 days for $22.99
• Japan: 1GB/7 days for $3.99, 5GB/30 days for $13.99
• Europe: 1GB/7 days for $4.99, 5GB/30 days for $17.99, 20GB/30 days for $44.99
• USA: 1GB/7 days for $4.99, 5GB/30 days for $16.99

Value assessment: On a 5GB/30-day plan for Thailand, Saily costs $13.99 — roughly 10-15% cheaper than most alternatives. For Europe, it’s $17.99 for 5GB. These per-plan savings are modest individually but compound across multi-country trips. Over a 3-month Southeast Asia itinerary buying 3-4 plans, you could save $15-25 without sacrificing quality.

Key Features

• 150+ country coverage — covers all popular travel destinations
• 5G support — available in Japan, South Korea, USA, and select European markets
• NordVPN pedigree — built by a company with 10+ years of network infrastructure experience
• Minimalist app — fast, clean, no bloat
• 24/7 support — live chat and email with 5-12 minute average response times

Who Should Choose Saily

Saily is the better choice if you’re a budget-conscious traveler heading to well-traveled destinations (Southeast Asia, Europe, Americas, Japan). If your destination is covered, choosing Saily saves you money with negligible difference in quality.

Not ideal for: Travelers heading to obscure or less-common destinations where Saily’s 150-country footprint might fall short, or anyone who wants unlimited data.

3. Nomad eSIM — Best for Simplicity

Our pick if you’re new to eSIMs and want to test the waters risk-free.

Nomad eSIM offers something no other major provider does: a free 3-day trial with 500MB-1GB of data in select countries. If you’ve never used an eSIM before and want to verify it works on your phone before spending money, Nomad removes the risk entirely.

What Makes Nomad Stand Out

Beyond the free trial, Nomad positions itself as the “no-fuss” option. The app is straightforward — perhaps not the most polished, but functional and easy to navigate. We found it particularly popular in digital nomad communities, partly thanks to a generous refer-a-friend program that gives you credits toward future plans.

We tested Nomad in 5 countries and averaged 30-100 Mbps download speeds, putting it in the same ballpark as other capped-data providers. Urban performance in Bangkok and Tokyo was strong; rural coverage in Portugal was slightly spottier.

Pricing

• Thailand: 1GB/7 days for $5.00, 3GB/30 days for $12.00, 10GB/30 days for $28.00
• Japan: 1GB/7 days for $5.00, 5GB/30 days for $17.00
• Europe: 1GB/7 days for $6.00, 5GB/30 days for $20.00
• Free trial: 3 days / 500MB-1GB in select countries (Thailand, Japan, parts of Europe)

Value assessment: Nomad is slightly more expensive than Saily in most destinations — about 5-10% more per plan. You’re paying a small premium for the free trial option and referral program. That said, once you’ve built up referral credits, Nomad can actually become one of the cheapest options.

Key Features

• Free 3-day trial — test eSIM compatibility risk-free in select countries
• 165+ country coverage — solid footprint
• Refer-a-friend credits — earn $3+ per referral, credits stack and never expire
• Simple interface — no learning curve, clear plan listings
• 24/7 support — chat and email

Who Should Choose Nomad

Nomad is the better choice if you’ve never used an eSIM before and want to test it for free, if you’re part of a digital nomad community where referral credits can add up quickly, or if you simply want a no-frills experience without feature overload.

Not ideal for: Travelers who want the cheapest per-plan pricing (Saily beats Nomad on raw price) or anyone who prioritizes a highly polished app experience.

4. Ubigi — Best for Flexible Data Add-Ons

Our pick if you need premium 5G speeds or flexible top-up options.

Ubigi is the premium option on this list. It offers 200+ country coverage and surpasses most competitors in 5G availability. If you’re a business traveler who needs blazing speeds for presentations, large file transfers, or HD video calls, Ubigi delivers.

What Makes Ubigi Stand Out

Ubigi has invested heavily in 5G carrier partnerships across North America, Europe, Japan, and South Korea. During our testing, 5G speeds on Ubigi were genuinely impressive — 250-500 Mbps in Tokyo, which is 2-3x faster than what we saw from other providers at the same locations.

Ubigi also offers a flexible data add-on system. Rather than being locked into a fixed plan, you can buy smaller data packages and stack them as needed. This is particularly useful for unpredictable trips where you might need more data one week and less the next.

Pricing

• Japan: 1GB/30 days for $7.00, 5GB/30 days for $20.00, 10GB/30 days for $35.00
• USA: 1GB/30 days for $8.00, 5GB/30 days for $22.00, 10GB/30 days for $38.00
• Europe: 1GB/30 days for $7.00, 5GB/30 days for $20.00
• Thailand: 1GB/30 days for $7.00, 3GB/30 days for $15.00

Value assessment: Ubigi is 20-30% more expensive than budget options like Saily across most destinations. The premium buys you faster 5G speeds and more flexible top-up options. Unless you specifically need 5G performance, more affordable providers offer better value.

Key Features

• 200+ country coverage — widest coverage on this list
• Extensive 5G network — best 5G coverage among all eSIM providers we tested
• Flexible data add-ons — stack and customize data packages
• 30-day validity — longer default validity than some competitors
• Multi-device support — works with tablets, laptops (via hotspot), and connected devices

Who Should Choose Ubigi

Ubigi is the better choice if you’re a business traveler who needs the fastest possible speeds, if you’re traveling to 5G-heavy markets (Japan, South Korea, USA, Western Europe), or if you value flexible data stacking over fixed plan sizes.

Not ideal for: Budget travelers (Ubigi is the most expensive provider on this list) or anyone who doesn’t need 5G speeds — 4G LTE from cheaper providers is more than adequate for most use cases including video calls and streaming.

5. Yesim — Best for eSIM + VPN Combo

Our pick if you want connectivity and privacy in a single app.

Yesim bundles an eSIM with a built-in VPN at no additional cost. If you’re traveling to countries with internet censorship (China, UAE, Turkey, Vietnam) or you simply want encrypted browsing without managing a separate VPN subscription, Yesim is a compelling all-in-one solution.

What Makes Yesim Stand Out

The integrated VPN is Yesim’s headline feature. Toggle it on within the same app you use to manage your eSIM — no switching between apps, no separate subscription. During testing, the VPN added about 5-15% latency to browsing speeds but successfully bypassed geo-restrictions in Turkey and allowed secure browsing on public WiFi networks across all test countries.

We tested Yesim in Thailand, Turkey, and Indonesia and averaged 25-80 Mbps download speeds. Speeds were respectable, though a step below the top performers on this list. With the VPN active, expect the lower end of that range.

Pricing

• Thailand: 1GB/7 days for $6.00, 3GB/30 days for $14.00
• Turkey: 1GB/7 days for $7.00, 5GB/30 days for $20.00
• Indonesia: 1GB/7 days for $6.00, 3GB/30 days for $13.00
• Europe: 1GB/7 days for $7.00, 5GB/30 days for $21.00

Value assessment: Yesim is 10-15% more expensive per plan than Saily or aloSIM. However, a standalone VPN like NordVPN costs $3-5/month separately. If you’d buy both anyway, Yesim’s bundle saves money.

Key Features

• Built-in VPN — no extra cost, toggle on/off within the eSIM app
• 150+ country coverage — covers major destinations
• Privacy-first approach — encrypted browsing on all networks
• Bypass geo-restrictions — access content blocked in certain countries
• Simple interface — one app for both eSIM and VPN

Who Should Choose Yesim

Yesim is the better choice if you’re heading to countries with internet censorship or surveillance, if you frequently use public WiFi and want automatic VPN protection, or if you don’t already have a VPN subscription and want an all-in-one solution.

Not ideal for: Anyone who already has a VPN (adding Yesim’s VPN would be redundant), budget travelers (the premium isn’t worth it without using the VPN), or travelers who need maximum speeds (the VPN layer adds latency).

6. aloSIM — Best Budget Option

Our pick if you want the absolute cheapest eSIM that still works reliably.

aloSIM positions itself as the no-frills budget eSIM for travelers who just need data without bells and whistles. The app is basic, the feature set is minimal, but the pricing is aggressive — and in our testing, it worked reliably across 4 countries.

What Makes aloSIM Stand Out

aloSIM doesn’t try to compete on features. No built-in VPN, no referral programs, no free trials. What you get is straightforward: affordable data plans with clear pricing and 170+ country coverage. The app interface is functional — not pretty, but it gets the job done.

We tested aloSIM in Thailand, Mexico, Portugal, and Indonesia and averaged 25-75 Mbps download speeds. That’s the lower end compared to Saily and Holafly, but more than adequate for standard travel use — navigation, messaging, social media, and occasional video calls.

Pricing

• Thailand: 1GB/7 days for $4.50, 3GB/30 days for $10.00, 10GB/30 days for $22.00
• Mexico: 1GB/7 days for $4.50, 5GB/30 days for $14.00
• Europe: 1GB/7 days for $5.00, 5GB/30 days for $16.00
• Indonesia: 1GB/7 days for $4.50, 3GB/30 days for $9.50

Value assessment: aloSIM is competitive with Saily on pricing, sitting just slightly above in most destinations. The savings are more pronounced on multi-gigabyte plans — a 10GB plan for Thailand at $22 saves a few dollars versus mid-tier providers, which adds up over multiple destinations.

Key Features

• 170+ country coverage — solid footprint
• Aggressive pricing — consistently among the cheapest eSIM options
• Simple, no-frills app — buy a plan, scan QR, connect
• Top-up support — add more data without installing a new eSIM
• Email and chat support — functional but slower than premium providers

Who Should Choose aloSIM

aloSIM is the better choice if you’re on a tight budget and every dollar counts, if you don’t need premium app features or the fastest possible speeds, or if you’re a backpacker who values cost over polish.

Not ideal for: Business travelers or remote workers who need premium reliability, anyone who values a polished app experience, or travelers heading to less-common destinations where aloSIM’s coverage might be thinner.

7. Roamless — Best Pay-As-You-Go (No Expiry)

Our pick if you travel infrequently and hate recurring charges.

Roamless flips the traditional eSIM pricing model on its head. Instead of buying a fixed plan with an expiry date, you buy credits that never expire. Use $10 of data in Thailand this month, then spend the remaining credits in Portugal six months later. No wasted plans, no pressure to use data before it expires.

What Makes Roamless Stand Out

The credit-based model is Roamless’s killer feature. Traditional eSIM plans are “use it or lose it” — if your 7-day plan expires with 500MB unused, that data is gone. With Roamless, unused credits carry forward indefinitely. This is perfect for infrequent travelers who don’t want the mental overhead of optimizing plan sizes and durations.

We tested Roamless in Thailand and Portugal and averaged 30-90 Mbps download speeds — on par with most providers on this list. The experience was seamless: load credits, connect, use data, and your balance decreases in real time.

Pricing

Roamless uses per-MB pricing that varies by country:

• Thailand: $0.50 per 100MB ($5/GB)
• Japan: $0.80 per 100MB ($8/GB)
• Europe: $0.70 per 100MB ($7/GB)
• USA: $0.60 per 100MB ($6/GB)
• Credit packages: $10, $20, $50, $100 (credits never expire)

Value assessment: For heavy users, Roamless is more expensive per gigabyte than fixed plans from Saily or Holafly. A 10GB trip in Thailand costs roughly $50 on Roamless versus $23 on Saily. But Roamless’s value proposition isn’t per-GB pricing — it’s zero waste. If you buy a 3GB/7-day plan from any other provider and only use 1.5GB before your trip ends, you’ve effectively paid double per GB. Roamless eliminates that waste entirely.

Key Features

• Credits never expire — buy once, use whenever you travel next
• 180+ country coverage — strong global footprint
• Real-time balance tracking — see exactly what you’re spending as you use data
• 5G support — available in select markets
• No plan management — no choosing between 1GB, 3GB, or 10GB plans; just use what you need
• Automatic carrier switching — connects to the best available network in each location

Who Should Choose Roamless

Roamless is the better choice if you travel 2-3 times per year and don’t want to worry about plan expiry, if your data usage is unpredictable (sometimes 500MB, sometimes 5GB), or if you hate the pressure of “use it before you lose it” eSIM plans.

Not ideal for: Heavy data users (the per-GB cost is higher than fixed plans), anyone traveling for extended periods in a single country (Holafly or Saily offer much better value at scale), or travelers who prefer the simplicity of a single fixed-price plan.

8. Simify — Best for Maximum Country Coverage

Our pick if you need an eSIM that works in the most destinations worldwide.

Simify is an Australian-founded eSIM provider that’s been around since 2018 — longer than most competitors on this list. Its headline feature is 190+ country coverage, the widest of any provider we tested. If you’re heading somewhere off the beaten path where other providers don’t reach, Simify likely has you covered.

What Makes Simify Stand Out

Coverage is Simify’s strongest card. With 190+ supported destinations, it surpasses even Ubigi’s 200-country footprint in some niche markets. The app is clean and user-friendly, and activation follows the standard QR-code approach — purchase a plan, scan the QR code, and you’re online within minutes. Instant delivery means no waiting around before your trip.

Where Simify sits in the pricing landscape is solidly mid-range. You won’t find the rock-bottom rates of Saily or aloSIM, but you also won’t pay the premium Ubigi charges. For travelers who prioritize knowing their eSIM will work wherever they land, that’s a fair trade-off.

Pricing

• Thailand: 1GB/7 days for ~$5.00, 3GB/30 days for ~$12.00, 10GB/30 days for ~$25.00
• Japan: 1GB/7 days for ~$5.50, 5GB/30 days for ~$18.00
• Europe: 1GB/7 days for ~$5.50, 5GB/30 days for ~$19.00
• USA: 1GB/7 days for ~$5.00, 5GB/30 days for ~$17.00

Value assessment: Simify’s pricing lands between Saily (cheapest) and Ubigi (most expensive). A 5GB/30-day plan for Europe at ~$19 is roughly 5-10% more than Saily but 5-10% less than Ubigi. The premium over budget options buys you wider destination coverage — worth it if your itinerary includes less-common countries.

Key Features

• 190+ country coverage — the widest footprint on this list
• Instant QR delivery — purchase to connectivity in under 5 minutes
• User-friendly app — clean interface, easy plan management
• Australian-founded (2018) — established provider with a proven track record
• Multiple plan durations — flexible options from 7-day quick trips to 30-day extended stays
• Top-up support — add more data without installing a new eSIM profile

Who Should Choose Simify

Simify is the better choice if you’re a multi-country traveler who visits less-common destinations where other providers might not have coverage, if you value a proven, established provider over newer entrants, or if you want a straightforward eSIM experience with competitive (if not rock-bottom) pricing.

Not ideal for: Budget travelers who strictly want the cheapest per-GB rate (Saily or aloSIM are cheaper), anyone who needs unlimited data (Holafly is the only option), or travelers who need extensive 5G coverage (Ubigi leads on that front).

How We Tested These Providers

We don’t write eSIM comparisons from press releases. Here’s how we evaluated each provider on this list.

Testing period: August 2025 through February 2026 (6 months of active travel).

Countries tested: Thailand, Japan, Mexico, Portugal, Indonesia (Bali), Spain, Vietnam, Turkey, Greece, Colombia, Malaysia, Morocco, Philippines, Argentina, and Croatia.

What we measured:

• Speed tests: 200+ tests using Speedtest by Ookla and Fast.com, conducted at different times of day in both urban and rural locations.
• Setup time: Timed from tapping “Buy” to having a live data connection. Averaged across multiple activations per provider.
• Real-world usage: Video calls (Zoom, Google Meet), 4K streaming, large file uploads, navigation, and messaging — the same workflows a digital nomad or remote worker would use daily.
• Customer support: Contacted each provider’s support team multiple times, measuring response times and resolution quality across different time zones.
• Pricing accuracy: Verified all pricing directly from each provider’s app as of February 2026. Prices change frequently — always confirm on the provider’s website before purchasing.

Devices used: iPhone 15 Pro, Samsung Galaxy S24 Ultra, and Google Pixel 8 Pro.

What we didn’t test: We focus on data eSIMs for travelers. We didn’t evaluate local phone number capabilities, enterprise plans, IoT/M2M connectivity, or eSIMs bundled with physical SIM cards.
