The Short Answer
Saily is the closest general alternative — same capped-data model, competitive pricing, backed by Nord Security. Nomad is the budget-first pick for well-covered, single-country trips. Ubigi is the one to use if you're headed to Japan specifically — its NTT Docomo routing beats every other provider we've looked at for network quality there — and its 10 GB plans were the cheapest of the four in most countries we track. None of them dethrones Airalo as the best all-around default, but each one wins in a specific situation.
Why Look Beyond Airalo
I recommend Airalo to most people who ask me — 200+ countries, the most polished app in the category, and pricing that's hard to beat on average. But "best on average" doesn't mean "best for your exact trip." Here's when it's worth checking an alternative before you buy.
Airalo isn't always cheapest for your specific destination
Airalo aggregates local carriers, and per-GB pricing shifts country by country and by plan size. At 10 GB and up, Nomad undercut Airalo in about two-thirds of the countries we track, and Ubigi's 10 GB plan was the cheapest of the four providers here in 55 of the 61 countries we could compare — $5 or more below Airalo's in more than half of them.
You want a stronger network partner for one destination
Airalo's coverage is broad but the underlying carrier varies by country. If you're headed to Japan specifically, a provider with a direct relationship to the country's top network can mean better signal in subways and rural areas.
You hit slow support during peak season
Airalo's support can stretch to a few hours during summer and holiday travel spikes. If that's happened to you, it's worth knowing what the alternatives look like on responsiveness.
You want a second data-only backup on a multi-leg trip
Some travelers run two eSIMs on longer trips — one as a primary, one as a backup if a network has a bad day in a specific city. Comparing providers up front makes that easier.
Saily — Closest Match on Price and Model
Saily is Nord Security's eSIM product — the same company behind NordVPN and NordPass. That pedigree matters more than it might sound: this isn't a startup figuring out mobile infrastructure for the first time, it's a company that already runs secure consumer apps at scale.
Functionally, it's the closest thing to Airalo on this list — capped data plans across 150+ countries, activated via QR code, managed in a clean app. 1 GB plans start at $3.99in most countries we track (as low as $1.99 in Austria and the Czech Republic). Saily's price edge is at that entry level: its 1 GB plan undercut Airalo's in 39 of 61 countries and lasts 7 days rather than 3. From 5 GB up, Airalo was cheaper in nearly every country we track, so compare both before buying a bigger plan. Top-ups are supported, so running low mid-trip doesn't mean reinstalling anything.
The trade-off is coverage and maturity. 150+ countries is still strong, but it's 50 fewer than Airalo, and the gaps tend to be in less-traveled regions — Central Asia, parts of Africa, smaller Pacific islands. For mainstream destinations (Western Europe, Southeast Asia, Japan, the Americas), you won't notice a difference.

Nomad — Budget-First, No Frills
Nomad doesn't try to impress you with extra features — no built-in VPN, nothing beyond a simple data plan that works. For travelers who just want to get online without paying for anything else, that simplicity is the whole appeal.
Coverage sits at 100+ countries, behind both Airalo and Saily, but the destinations it does cover — Southeast Asia, Japan, Western Europe, the Americas — are priced well, especially for bigger plans. On single-country trips, Nomad beat Airalo at 10 GB in 39 of 61 countries we track and at 20 GB in 44 of 58 — in Japan, for example, 10 GB is $16 on Nomad versus $17 on Airalo, and 20 GB is $23 versus $24.
The catch is support: email only, with response times from a few hours up to a day. There's no live chat. If your setup goes smoothly — which it usually does — you'll never notice. If something goes wrong at an inconvenient hour, you're waiting for an email back.

Ubigi — Best Network Quality, Especially in Japan
Ubigi is owned by NTT — Japan's largest telecom company, and one of the largest in the world. That ownership isn't just a corporate footnote: in Japan, Ubigi routes through NTT Docomo, the country's best network, which means noticeably stronger signal in subway stations, rural areas, and mountainous regions where marketplace-model providers on secondary networks can struggle.
Coverage is broad — 190+ countries, nearly matching Airalo — and pricing is sharper than its reputation. In Japan, 1 GB starts at $3.50 (3 days) and 10 GB is $14 for 7 days or $16.50 for 30 days, versus $16 on Nomad, $17 on Airalo, and $17.99 on Saily. Across the countries we track, Ubigi's 10 GB plan was the cheapest of these four providers in 55 of the 61 countries we could compare. Ubigi also offers recurring subscription plans for frequent travelers visiting the same region repeatedly.
The trade-off is polish. Ubigi's app and purchase flow feel more utilitarian than Airalo's or Saily's, and support is email/portal-based rather than live chat. If network quality in a specific destination matters more to you than app design, that trade-off is an easy one to make.

How to Choose
Stick with Airalo if you're…
- Visiting a less common destination other providers don't cover
- A frequent traveler who wants every trip's eSIM in one app
- Not sure yet, and want the safest default choice
Check an alternative if you're…
- Buying a small 1 GB plan — Saily usually undercuts Airalo and lasts longer
- Buying 10 GB or more — check Ubigi (usually cheapest at 10 GB) and Nomad (usually cheapest at 20 GB)
- Headed to Japan and want the strongest network — go with Ubigi
- Budget-first on a single well-covered route — try Nomad
- Choosing based on the company behind the product — Saily's Nord Security backing stands out
The Verdict
I still reach for Airalo first on most trips — the country breadth and app quality make it the safest default. But "default" isn't the same as "always right," and running a quick comparison before you buy costs nothing. Saily is worth checking for small plans. Nomad is worth checking on a budget, single-country trip, especially at 20 GB. And Ubigi is worth checking any time you're buying around 10 GB — and every time Japan is on the itinerary, where the NTT Docomo routing is a real, noticeable difference in network quality that no marketplace-model provider can match.
