Saily vs Yesim (2026): Which Travel eSIM Is Actually Better?

Saily is the better all-round choice for most travellers thanks to sharper per-GB pricing on larger plans, a more polished app and notably faster support, while Yesim wins for light users who want a tiny cheap starter plan, pay-as-you-go flexibility and virtual phone numbers.

Saily and Yesim chase the same traveller — someone who wants mobile data abroad without paying carrier roaming — but they arrived from opposite directions. Saily is the travel connectivity arm of Nord Security, the company behind NordVPN, and the product is packaged accordingly: an ad blocker, web protection and a "virtual location" tool sit alongside the data plans. Yesim is a Swiss operator that has been in the eSIM business longer than most of the current crop, and its lineup reads like a small telco's: pay-as-you-go balances, top-ups, virtual phone numbers, unlimited tiers stretching from one day to ninety.

We compared them on the things that actually decide a trip: what you pay per gigabyte, whether the network you land on is any good, what happens when something breaks at 11pm in an unfamiliar airport, and how much friction sits between tapping "buy" and having a working connection.

Saily Overview

Reasons to choose Saily:

• Entry plans from approximately USD 1.99 for 1GB/7 days on select countries — genuinely useful for a short trip.
• Better value on larger single-country allowances; pay-as-you-go sits around ~USD 4/GB.
• Multi-carrier in many markets (averaging roughly ~1.5 carriers per country), so a weak network is not always a dead end.
• Polished apps — iOS rated around ~4.7 and Android around ~4.6 — with fast, guided installation.
• Support via in-app chat and email, 24/7, with typical replies under approximately 2 hours.
• Trustpilot sits near ~4.7 across roughly ~25,000 reviews, an unusually large sample for this category.
• Extras that occasionally earn their keep: ad blocker, web protection, virtual location across ~115+ locations, an optional US phone number, and a premium "Saily Ultra" tier bundling unlimited data with airport lounge passes and NordVPN.

Reasons to avoid Saily:

• Every plan expires. Unused data disappears when the validity window closes.
• The security extras duplicate what you already have if you run a VPN — you are paying for a bundle you may not use.
• Unlimited tiers are expensive, from approximately USD 89 for 30 days in some regions.
• Fewer exotic billing options: no true balance-style wallet, no virtual numbers beyond the US add-on.

Saily's real advantage is boring competence. Coverage is marketed at 200+ destinations, and while some sources count closer to ~150 countries with practical, buyable plans, the countries most travellers actually visit are well served. Plan durations of 10, 15, 20, 25 and 30 days across many regions mean you can size a plan to a trip instead of rounding up to the nearest month. 5G is available where the underlying networks support it, and hotspot works normally, drawing from the same allowance.

Where Saily gets criticised fairly is the framing. Nord Security sells security, so Saily is sold partly as a security product. If you already pay for a VPN, the ad blocker and virtual location are pleasant but not decisive, and they do not make a gigabyte cheaper.

Yesim Overview

Reasons to choose Yesim:

• The cheapest way in of the two: from approximately USD 0.54–0.60 for 500MB/3 days on select regional plans, with Europe regional starting around there.
• A genuine pay-as-you-go international plan covering ~170+ countries, with top-ups from a minimum of around ~USD 10.
• Unlimited plans available from 1 to 90 days across various regions, subject to fair-use policies — the 1-day and short-burst options are useful.
• Virtual phone numbers in Canada, Israel, the Netherlands and the US for SMS and account registrations.
• An included VPN, which is a real perk if you are on iPhone.
• Swiss-based operation, and fixed plans spanning roughly ~USD 8.40 to ~USD 130.80 depending on data and validity — a wide ladder.

Reasons to avoid Yesim:

• A conspicuous gap in the lineup: no 1GB or 2GB plans, so light users jump from 500MB straight to much larger bundles.
• The bundled VPN is iOS-only. Android users simply do not get it.
• Support is inconsistent. Marketing points at roughly ~6-minute average replies; in practice waits run from a few minutes to over an hour.
• Coverage quality varies more than the destination count suggests, because some partner networks are still 3G-only.
• Trustpilot sits around ~4.3, on a much smaller review pool than Saily — less signal, and a lower score.

Yesim's pitch is flexibility. If you have ever bought a 5GB plan to use 900MB, the pay-as-you-go model is attractive: you hold a balance, top it up when you need it, and the coverage footprint follows you across borders without buying a new plan for each country. Coverage is marketed at 200+ destinations, with roughly ~147 countries on fixed global plans and ~170+ on the pay-as-you-go international plan.

The catch is consistency. Yesim's destination list is impressive on paper, but a plan is only as good as the partner network it lands on, and a 3G-only partner in a secondary market turns a "5G-ready" eSIM into something you would not want to rely on for video calls.

Coverage

Both providers advertise 200+ destinations, and both numbers deserve an asterisk. Saily's practical catalogue is closer to ~150 countries once you filter for destinations with plans you can actually buy at a sensible price. Yesim splits its footprint: roughly ~147 countries on fixed global plans, and ~170+ on the pay-as-you-go international plan, which is the broader of its two products.

The more useful question is not how many flags are on the map but what happens when you arrive. Saily's multi-carrier approach in many countries — averaging around ~1.5 carriers per country — matters because a single-carrier eSIM in a country where that carrier has patchy rural coverage is a bad trip. Yesim's weak point is the tail of its network list: where partners are 3G-only, throughput and latency fall off a cliff, and no marketing claim about 5G readiness changes that.

For mainstream itineraries — Western Europe, the US and Canada, Japan, Thailand, Mexico, Brazil — both work, and the differences are marginal. For secondary destinations, Central Asia, parts of Africa, smaller Pacific islands, check the specific country page before you buy, on either provider. Neither company's headline number tells you whether the network in the one city you care about is good.

Pricing and value

This is where the comparison stops being symmetrical. Yesim is unbeatable on the smallest possible purchase: from approximately USD 0.54–0.60 for 500MB over 3 days on select regional plans is closer to an impulse buy than a phone plan. If you want maps, messaging and a boarding pass for a weekend, that is very hard to argue with.

Saily wins on the middle and upper end. For larger single-country allowances it generally offers better value per gigabyte, and pay-as-you-go at around ~USD 4/GB is competitive. Its entry point — from approximately USD 1.99 for 1GB/7 days on select countries — also fills exactly the gap Yesim leaves open, because Yesim offers no 1GB or 2GB plans at all. A traveller who needs 1.5GB has to buy 500MB and top up awkwardly, or overshoot into a much bigger bundle.

On regional plans the picture is genuinely mixed, and anyone telling you otherwise is selling something. Yesim tends to be slightly cheaper for Europe and North America. Saily leads in Asia-Pacific. Yesim's fixed plans span roughly ~USD 8.40 to ~USD 130.80 depending on data and validity, so there are cheap and expensive corners of both catalogues.

The honest summary: price the specific trip, in both apps, before you commit. A two-week Europe trip and a two-week Vietnam trip can produce opposite winners.

Unlimited data

Both offer unlimited plans, and both come with fair-use policies — which is the part worth reading. Saily's unlimited pricing starts from approximately USD 89 for 30 days in some regions, and the premium "Saily Ultra" tier bundles unlimited data with airport lounge passes and NordVPN. It is expensive, and for most travellers a 10GB or 20GB plan is better value than paying for a ceiling you will not touch.

Yesim is more flexible here: unlimited plans run from 1 to 90 days across various regions. A one-day unlimited plan is a genuinely good product for a long layover or a single heavy working day. The 90-day option is unusual and useful for a long stay.

The caveat for both: "unlimited" in the travel eSIM market means unlimited subject to fair use, which in practice can mean throttling after a threshold or restrictions on sustained tethering. If you plan to work off the hotspot all day, every day, read the fair-use terms on the specific plan rather than trusting the word on the buy button.

Support and user experience

This is Saily's clearest win. Support runs 24/7 via in-app chat and email, with typical responses under approximately 2 hours, and the apps are rated around ~4.7 on iOS and ~4.6 on Android. Installation is guided, the usage meter is legible, and buying a top-up takes seconds. That combination is why its Trustpilot score sits near ~4.7 across roughly ~25,000 reviews — a big enough sample that the number means something.

Yesim's support is its weakest link. It offers live chat, email and a FAQ, and its marketing cites average replies around ~6 minutes, but real-world experience is inconsistent: sometimes a few minutes, sometimes over an hour. When your connection is the thing that is broken, an hour is a long time. Trustpilot around ~4.3 on a much smaller pool is consistent with that. The app works, but the iOS-only VPN is a sign of uneven product investment — an Android user is buying a slightly different, slightly thinner product for the same money.

Which should you choose?

• Backpacker / budget traveller — Yesim. The ~USD 0.54–0.60 starter plan and the pay-as-you-go balance suit unpredictable, multi-country routes where you cannot forecast usage.
• Business traveller — Saily. Fast support, reliable multi-carrier connections and clean expensing matter more than saving a couple of dollars, and a stuck eSIM before a client meeting is the expensive scenario.
• Family — Saily, marginally. Larger allowances price better per gigabyte, hotspot works predictably for sharing with kids' tablets, and guided installation across several phones is less painful.
• Digital nomad — depends on the region. Saily for Asia-Pacific bases and if you want the bundled security stack; Yesim for long European stays, where its regional pricing and 90-day unlimited options are strong. If your bigger frustration is data expiring between trips, a provider like HOLASIM — non-expiring data and multilingual human support — is worth a look alongside these two.

FAQ

Is Saily cheaper than Yesim?

It depends on the size of the plan. Yesim is cheaper at the very bottom, from approximately USD 0.54–0.60 for 500MB/3 days. Saily generally offers better value per gigabyte on larger single-country plans and has an entry plan from approximately USD 1.99 for 1GB/7 days. On regional plans it is mixed: Yesim tends to be slightly cheaper for Europe and North America, Saily leads in Asia-Pacific.

Is Yesim's unlimited data really unlimited?

It is unlimited subject to fair-use policies, like almost every unlimited travel eSIM. Plans are available from 1 to 90 days across various regions. Heavy sustained tethering is the usual trigger for throttling, so check the terms on the specific plan if you intend to work off the hotspot daily.

Do Saily and Yesim eSIMs expire?

Yes. Saily's plans all have a validity window — commonly 10, 15, 20, 25 or 30 days — and unused data is lost when it closes. Yesim's fixed plans also expire, but its pay-as-you-go balance is topped up as needed, with a minimum top-up around ~USD 10, which behaves more like credit than a countdown.

Which one is better for hotspot and tethering?

Saily, slightly. Tethering is supported and draws from the plan allowance, and connections are more consistently fast thanks to multi-carrier access in many countries. Yesim supports hotspot on most plans, but where a partner network is 3G-only, sharing that connection with a laptop is unpleasant.

Can I get a phone number with Saily or Yesim?

Both, in limited form. Saily offers an optional US phone number. Yesim offers virtual numbers in Canada, Israel, the Netherlands and the US, which is the stronger option if you need an SMS-capable number to register accounts or receive verification codes abroad.

Is Saily's built-in security worth paying for?

Only if you do not already have a VPN. The ad blocker, web protection and virtual location across ~115+ locations are competently done, but they are bundled value, not a discount on data. If you already run NordVPN or an equivalent, judge Saily purely on price, coverage and support.

Saily is the safer default. It costs a little more at the very bottom of the market, but the per-gigabyte pricing on real-world plan sizes is better, the app is more polished, multi-carrier access makes the connection more predictable, and support answers in under approximately 2 hours instead of sometimes over an hour. Yesim is the more interesting product for a specific kind of traveller: someone who wants to spend under a dollar to get online for a weekend, hold a top-up balance across many countries, grab a one-day unlimited plan, or pick up a virtual number for SMS. Choose Yesim for flexibility and the lowest possible entry cost; choose Saily when the connection needs to just work and someone needs to answer quickly when it does not.
