Best eSIM for international travel: 2026 comparison
We priced a week in Germany and a week in Singapore at six travel eSIM providers on the same day. Coverage, unlimited plans, refund rules, and how to pick the best eSIM for international travel.
The best eSIM for international travel is the one that covers every country on your route, fits how much data you use, and costs the least for the days you're away. For one country, pick a country plan. For several, pick a regional or global plan.
That's the short answer, but it doesn't help much when every app on your screen promises "200+ destinations". So we priced the same two trips, a week in Germany and a week in Singapore, at six providers on the same day, straight from each provider's own website. Below you'll find the numbers, what each kind of plan is good for, and a quick way to choose the best eSIM for international travel for your own trip.
One thing to know first: 1001SMS sells travel eSIMs too. That's why we stuck to facts you can check yourself (prices, coverage and terms as listed on 31 October 2026) and compared every provider on the same points. We aren't affiliated with any other brand named here. Prices change often, so check the provider's page before you buy.
Key takeaways
- There's no single best eSIM for international travel. The right one depends on where you go, for how long, and how much data you use.
- Unlimited day passes suit heavy use on short trips. Fixed data suits light use and longer trips.
- Compare what your whole trip costs, not the "from" price on a home page.
- Most travel eSIMs are data only. Keep your own SIM on for calls and bank codes.
- Install the eSIM at home on Wi-Fi, before you fly. Even the best travel eSIM needs an internet connection to set up.
The best eSIM providers for international travel 2026: how we compared them
To find the best eSIM for international travel, we took five well-known travel eSIM brands, Airalo, Holafly, Nomad, Saily and Ubigi, and added our own. Then we checked all six on the same six points.
- Countries covered. Every stop on your route, including the airport where you change planes.
- Data and speed. How much data you get, and how fast it is after any daily limit.
- Days it lasts. A 7-day plan for a 10-day trip means buying twice.
- Price per day. What the whole trip costs, divided by its days.
- When it starts. At purchase, when you install it, or when you land.
- Refund rule. What happens if your plans change before you use it.
For each trip we priced two plans. The first is for light use (maps, messages, a few web pages): the cheapest plan with at least 1 GB that lasts at least 7 days. The second is for heavy use (video calls, social media, a laptop on hotspot): the 7-day unlimited plan. All prices are in US dollars, as each provider listed them on 31 October 2026.

Coverage, phone numbers and refunds
| Provider | Destinations | Global plan | Phone number | Refund for an unused eSIM |
|---|---|---|---|---|
| 1001SMS | 197 countries and territories, plus 34 regional plans | 117 or 127 countries, from $11.50 (1 GB, 7 days) | Data only | No, once delivered. A failed order, or a fault we confirm, goes back to your balance |
| Airalo | 200+ | 168 countries, from $8.50 (1 GB, 7 days) | Data only, except Discover+ (US number) | Within 14 days, if not activated |
| Holafly | 200+ | 142 countries, from $9.50 (unlimited, 1 day) | Data only, except the monthly Holafly Plans | Within 6 months, if not activated |
| Nomad | 200+ | 123 destinations, from $12 (1 GB, 7 days) | Data only, except some Thailand, UK and Maldives plans | Within 30 days, if not installed or activated. Unlimited plans aren't refundable |
| Saily | 200+ | 121 countries, from $8.99 (1 GB, 7 days) | Data only, with an optional US number add-on | Within 30 days, if not installed or activated |
| Ubigi | 200+ | World plan, about 200 destinations, from $7 (500 MB, 30 days) | Data only | Within 14 business days, if the QR code hasn't been scanned |
So which is the best eSIM for international travel on price alone? On these two trips, 1001SMS had the lowest price in every column: $1.43 and $11.91 for the week in Germany, $1.38 and $9.45 for the week in Singapore. The gap was widest on unlimited plans, where the other five charged $19 to $27.50 for a week.
Two things to weigh against price. First, the full-speed allowance differs: 1 GB a day with us, 2 GB a day at Nomad, 3 GB a day at Airalo, and 20 GB for the whole week at Ubigi. If you burn through several gigabytes a day, that matters. Second, the refund rules differ. The other five refund an eSIM you haven't used within their windows (Nomad leaves out its unlimited plans), while ours can't be refunded once it's delivered. If your dates might still move, that's worth knowing.
1001SMS
Plans for 197 countries and territories, 34 regions and two global plans, sold as fixed data or as unlimited day passes. In Germany and Singapore, a day pass gives you 1 GB a day at full speed and then keeps going at 1 Mbps. Longer passes cost less per day: the 7-day prices above already include a 10% discount. The QR code arrives as soon as you pay, the days start counting when the eSIM first connects, and a failed order goes straight back to your balance. The same balance pays for phone numbers, which comes up again below.
Airalo
Airalo lists 200+ locations. In Germany, its smallest plan that lasts a week was 3 GB for 7 days ($8.00), and its unlimited week ($24.00) runs at full speed for 3 GB a day, then at 1 Mbps. For most packages, the days start when the eSIM connects to a supported network. Rechargeable eSIMs can be topped up, and the global Discover plan covers 168 countries.
Holafly
Holafly sells unlimited data only, priced by the number of days, from 1 to 90. A week in Germany or Singapore was $27.50, and 30 days in Germany $76.50. Hotspot sharing is capped at 1 GB a day. The plan starts when the eSIM first connects, and you can ask for a refund up to six months after purchase if it hasn't been activated.
Nomad
Nomad lists 200+ destinations and sells both fixed data and unlimited plans. In Germany, 1 GB for 7 days was $4.50 and an unlimited week $23, with 2 GB a day at full speed, then 1 Mbps. In Singapore, unlimited plans came in 5 and 10 days rather than 7. Plans start with your first data use, and a few (Thailand, UK, Maldives) include calls and texts.
Saily
Saily lists 200+ destinations. A week with 1 GB was $4.49 in Germany and $3.99 in Singapore. The unlimited week was $23.99 and $26.99, with a daily high-speed allowance and then about 1 Mbps. The plan starts when you land, or 180 days after purchase, and a US phone number is available as an add-on.
Ubigi
Ubigi lists 200+ destinations. In Singapore, 1 GB for 7 days was $3 and an unlimited week $19. In Germany the smallest plan was 3 GB for 15 days at $4, and an unlimited week $22. Its unlimited plans give 20 GB at full speed in total, then 2 Mbps. Plans start when you arrive in a covered country, and you can top them up.
Fixed data or unlimited: which is the best eSIM for international travel for you?
There's no best eSIM for international travel in general, only the best one for how you use your phone. A fixed data plan gives you one allowance for the whole trip, say 1 GB for 7 days. Use it gently and it lasts. Stream a film and it's gone.
An unlimited day pass gives you a fresh allowance at full speed every day, and keeps you online after that, just slower. You never run out, so you never have to buy a second plan halfway through the trip.
Go for fixed data if you mostly use maps, messages and the odd web page, if you'll be on hotel Wi-Fi most evenings, or if the trip is long and slow.
Go for unlimited if you make video calls, post a lot of photos, share a hotspot with a laptop, or just don't want to watch a counter.
Whichever you pick, read the speed rule. Every "unlimited" plan has one, and it decides how the plan feels in the evening. 1 Mbps is fine for maps and messages, but video will be slow.
Country, regional or global plan?
A country plan is the cheapest way to cover one country, so for a single destination the best travel eSIM is almost always a country plan. A week in Berlin and Munich needs nothing more than an eSIM Germany plan.
A regional plan covers several countries with one eSIM, so you don't buy a new plan at every border. Read its country list, though. Regional plans with similar names include different countries, and the one you change planes in may be missing.
A global plan covers the most countries and is made for trips across continents. You pay for that reach. At 1001SMS, 1 GB for 7 days was $1.43 for Germany alone, $7.25 on the 41-country Europe plan and $11.50 on the 117-country global plan.
Stopovers count as well, and the best eSIM for international travel on a route like that is often two plans, not one. If you're spending two days in Singapore on the way to Australia, a short eSIM Singapore day pass covers the stopover, and a second eSIM covers the rest of the trip. Most phones can store several eSIMs and switch between them in settings.
How to find the cheapest travel eSIM for your trip
The cheapest travel eSIM is the one that fits your trip with the least left over, and it's rarely the one with the lowest headline price. A few habits get you there:
- Price the whole trip. Multiply a day pass by your days, or check that a fixed plan lasts long enough. Two short plans usually cost more than one that fits.
- Look past the "from" price. The headline figure is usually the smallest plan in the cheapest country.
- Buy for the use you really have. If you're on Wi-Fi every evening, a small fixed plan may be all you need.
- Check when the clock starts. All six providers here start counting when the eSIM first connects or when you land (at Airalo, for most packages), not when you buy. Installing early costs you nothing.
- Mind the refund rule if your trip might move. With 1001SMS, buy once your dates are set.
What a travel eSIM won't do
Even the best eSIM for international travel has limits. Most travel eSIMs, ours included, are data only: they give you the internet, not a phone number. That's fine for WhatsApp, maps and email, but your bank can't text a code to the eSIM.
The fix is simple. Keep your own SIM switched on as a second line for calls and texts, with its data roaming turned off, and codes from home keep reaching you without a roaming bill.
If you need a number in the country you're visiting, say to sign up for a local taxi or food delivery app, that's a separate product. On 1001SMS you can get a number for a single code or a virtual number you keep for weeks or months. They're real mobile numbers rather than VoIP, and that's what many apps check before they send a code (our guide to VoIP numbers explains why). If a single-code number gets no SMS, the money goes back to your balance automatically, and your eSIM and your numbers share that one balance.
The best eSIM app for travel, in five minutes
- Check your phone. It has to support eSIM and be unlocked. If your settings offer "Add eSIM" or "Add mobile plan", you're fine.
- List every country on your route, stopovers included.
- Decide: light use or heavy use. Fixed data for light, unlimited for heavy.
- Compare the price of the whole trip at two or three providers, using the tables above.
- Install at home on Wi-Fi, then switch the eSIM on as your data line when you land.
That's all it takes to pick the best eSIM for international travel. Whichever you choose, the best eSIM app for international travel is the one you've installed and checked before you leave. Setting up an eSIM needs an internet connection, so do it at home, not in the arrivals hall.
