If you’ve ever landed in a new country and spent your first twenty minutes hunting for airport WiFi just to order a ride, you already know why eSIMs have taken over from physical SIM cards for most travelers. No more finding a kiosk, no more digging out a SIM ejector tool, no more losing your home SIM in a hotel room somewhere. You scan a QR code before you board, and by the time you land, you’ve got data. The catch is that “eSIM” isn’t one product — pricing, coverage, and data allowances vary a lot between providers, and picking the wrong one means either overpaying for data you don’t use or running out mid-trip.
I’ve compared five of the providers travelers mention most often, from the biggest local-plan catalog to the one offering genuinely unlimited data. The short version: Airalo is the one I point most people toward first because of its sheer country coverage and easy setup, and Holafly is the better pick if you specifically want unlimited data without watching a usage counter.
Who This Comparison Is Not For
If you’re traveling to a country where your existing carrier already offers a reasonably priced international roaming add-on, it’s worth comparing that against an eSIM before assuming a third-party provider is cheaper — for short trips to a single nearby country, your existing carrier sometimes wins. If your phone doesn’t support eSIM (this rules out most phones older than about 2020), none of these will work for you, and you’ll need a physical SIM instead. And if you need a permanent local phone number for banking or two-factor authentication in a specific country, a local carrier SIM is usually a better fit than a travel eSIM, which is built for data first.
This comparison is for travelers, digital nomads, and anyone who wants reliable mobile data the moment they land without hunting for a local SIM shop.
How I Compared Them
1. Coverage and region variety. A good travel eSIM needs to cover where you’re actually going, not just the most popular tourist destinations. I looked at how many countries each provider supports and whether local, regional, and global plan options exist.
2. Real cost per GB. Headline prices can be misleading when data allowances differ. I looked at what you’d actually pay per gigabyte across a range of plan sizes, not just the cheapest entry-level option.
3. Setup experience and reliability. An eSIM is only useful if it actually activates without a fight. I looked at how straightforward installation is, how clear the instructions are, and how each provider handles support when something goes wrong.
Quick Comparison Table
| Coverage | Entry Price | Data Style | Best Known For | |
|---|---|---|---|---|
| Airalo | 200+ countries | ~$4.50 (local, 1GB) | Fixed data packages | Largest local eSIM catalog |
| Holafly | 160+ countries | $19.50 (5 days, unlimited) | Unlimited data | Flat-rate unlimited data |
| Saily | 200+ countries | $1.79 (1GB, 7 days) | Fixed + subscription (Ultra) | Budget pricing, NordVPN heritage |
| Nomad eSIM | 200+ destinations | ~$3.50 | Fixed packages + bulk bundles | Lowest cost per GB |
| USIMS | 120+ countries | $9 (10GB, global) | Fixed data packages | Simple top-ups, budget global plans |
Airalo — Best Overall for Most Travelers
Airalo is usually the first name that comes up in eSIM conversations, and in my experience that’s earned by sheer breadth: local eSIMs for well over 200 countries, plus regional and global options if you’re covering multiple destinations on one trip. The app itself is genuinely easy to use — browsing, buying, and installing an eSIM takes a few minutes, and the interface clearly shows how much data you have left, which some competitors bury in a menu.
| Coverage | 200+ countries (local/regional/global plans) |
| Entry price | ~$4.50 (1GB local plan) |
| Data style | Fixed data packages |
| Setup | QR code, app-based, typically ready in minutes |
| Best known for | Largest local eSIM catalog |
- The largest catalog of local, single-country eSIMs of any provider on this list
- App is polished and easy to navigate, even for first-time eSIM users
- Regional and global plans available for multi-country trips
- Frequent promotions and a referral credit system
- Fixed data allowances mean you need to estimate usage in advance, unlike unlimited options
- Global plans cost more per GB than buying local eSIMs individually
- Customer support is primarily chat-based, with no phone line
Holafly — Best for Unlimited Data
Where most eSIM providers sell you a fixed number of gigabytes, Holafly’s core plans are unlimited — you pay a flat rate for 5, 10, or 30 days and don’t think about data again until the plan expires. I’ve found this genuinely reduces trip-planning friction, since you’re not trying to estimate how many GB a week of maps, messaging, and social media will actually use. Pricing is also flat across all 160+ destinations, so a plan to Japan costs the same as a plan to Turkey.
| Coverage | 160+ destinations |
| Entry price | $19.50 (5 days, unlimited) |
| Data style | Unlimited (flat rate) |
| Pricing structure | Same price across all destinations |
| Best known for | Flat-rate unlimited data |
- Unlimited data on core plans, with no need to estimate usage in advance
- Flat pricing regardless of destination makes budgeting simple
- Monthly subscription option (Holafly Plans) available for frequent travelers
- “Always On” low-data fallback keeps you connected even when a plan isn’t active
- More expensive than fixed-data competitors if you only need a small amount of data
- Fewer total destinations covered (160+) than Airalo or Saily (200+)
- “Unlimited” plans are typically subject to fair-use throttling after very high usage
Saily — Best Budget Option with a Privacy Pedigree
Saily is built by Nord Security, the company behind NordVPN, and that heritage shows up in the app’s polish and in a customer base that already trusts the brand for privacy tools. What stood out to me during research is the entry pricing — plans start under $2 for smaller data amounts in many popular destinations, which undercuts most competitors for short trips. For travelers who want more structure, Saily Ultra offers monthly subscription tiers instead of per-trip purchases.
| Coverage | 200+ countries and territories |
| Entry price | $1.79 (1GB, 7 days) |
| Data style | Fixed packages + Saily Ultra subscription |
| Backed by | Nord Security (NordVPN’s parent company) |
| Best known for | Budget pricing, NordVPN heritage |
- Some of the lowest entry-level prices on this list for short trips
- Backed by Nord Security, with the same app quality and support infrastructure as NordVPN
- Saily Ultra subscription tiers suit frequent travelers who don’t want to rebuy per trip
- 200+ countries and territories covered
- Newer to the market than Airalo or Holafly, so fewer long-term user reviews
- Ultra subscription tiers add complexity if you only travel occasionally
- Some remote destinations carry a significant price premium over popular routes
Nomad eSIM — Best for Cost Per GB
Nomad’s pitch is straightforward: the lowest realistic cost per gigabyte across most destinations, especially once you factor in the Value Bundles introduced in 2026 that let you buy data in bulk at a discount. For a heavy data user — someone tethering a laptop or streaming regularly while traveling — that per-GB math adds up fast compared to providers optimized around convenience rather than price.
| Coverage | 200+ destinations, 4G/5G in 170+ countries |
| Entry price | ~$3.50 |
| Data style | Fixed packages + bulk Value Bundles |
| Free trial | 1GB, 3-day trial |
| Best known for | Lowest cost per GB |
- Consistently among the cheapest cost-per-GB across popular destinations
- Value Bundles offer up to 50% off regular pricing for bulk data purchases
- Free 1GB, 3-day trial lets you test the network before committing
- Covers 200+ destinations with automatic 4G/5G network switching
- The app and plan-browsing experience is less polished than Airalo’s
- Best pricing requires buying in bulk, which doesn’t suit short or one-off trips
- Brand recognition is lower, so less community troubleshooting content exists online
USIMS — Best for Simple, No-Frills Global Plans
USIMS keeps things simple: buy a plan, get data, top up when it runs out. Its global plans are genuinely inexpensive for the data included, and the ability to keep your home SIM active for calls and texts while running USIMS purely for data is a detail some competitors don’t handle as cleanly. That said, research turned up more mixed feedback here than for the other four providers — some users report smooth activation, others report installation problems and slow support responses.
| Coverage | 120+ countries (some sources cite 200+) |
| Entry price | $9 (10GB, global plan) |
| Data style | Fixed data packages, easy top-ups |
| Dual SIM | Keeps home SIM active for calls/texts |
| Best known for | Simple top-ups, budget global plans |
- Inexpensive global plans, especially for travelers who mainly need data, not calls
- Keeps your home SIM active for calls/texts alongside USIMS data, useful for 2FA
- No contracts — top up or buy a new eSIM whenever you need more data
- Simple app with straightforward plan selection
- Customer support has been criticized as difficult to reach when problems come up
- Some users report activation issues that weren’t clearly resolved
- Coverage claims vary by source (120+ to 200+ countries), so it’s worth double-checking your specific destination before buying
Which One Should You Actually Pick? (By Use Case)
If you’re traveling to multiple countries and want the simplest setup: Airalo’s local and regional plan catalog covers the most ground with the least guesswork.
If you don’t want to think about data limits at all: Holafly’s unlimited plans and flat pricing remove the need to estimate usage before you go.
If budget is the deciding factor and you already trust Nord Security’s other products: Saily’s entry pricing and Ultra subscription options are hard to beat.
If you’re a long-term traveler or heavy data user tracking cost per GB: Nomad’s Value Bundles offer the best realistic price at volume.
If you mainly need cheap global data and want to keep your home number active: USIMS covers that specific need, provided you’re comfortable with its more mixed support reputation.
Do I need to unlock my phone to use an eSIM?
Your phone needs to support eSIM technology (most phones from 2020 onward do), and it generally needs to be carrier-unlocked. Check both before buying a plan.
Can I use multiple eSIMs at once?
Most modern phones support multiple eSIM profiles, though usually only one or two can be active for data at the same time. Check your specific phone model’s limit.
What happens if I run out of data mid-trip?
With fixed-data providers like Airalo, Saily, Nomad, and USIMS, you can typically top up or buy a new plan directly in the app. With Holafly’s unlimited plans, this isn’t a concern unless you hit fair-use throttling limits.
Is eSIM data as fast as a local SIM card?
In most cases, yes — eSIM providers typically partner with major local carriers, so you get comparable 4G/5G speeds. Coverage can vary in rural or remote areas regardless of provider.
Bottom Line
For most travelers who want broad coverage and an easy setup, Airalo remains the safest first choice. If unlimited data without watching a counter matters more to you than price, Holafly is worth the premium. Whichever you choose, check current pricing and coverage for your specific destination before buying, since plans and rates change frequently across all five providers.
