Saily eSIM Review 2026: How It Compares to Airalo and Yesim

The eSIM market has matured rapidly. Three years ago, travellers who wanted local data abroad had two realistic options: buy a local SIM at the airport (involving a SIM swap and potentially losing access to their regular number) or pay expensive carrier roaming rates. Today, a prepaid eSIM installed at home in three minutes is the standard approach — and the question is which provider to use.

Saily, developed by Nord Security (the company behind NordVPN), entered this market in 2023. In 2026, it has established itself as a credible third option alongside Airalo and Yesim. This review covers what Saily actually offers, where it performs well, where it falls short, and how to decide between the three.

What Saily is

Saily is a prepaid eSIM service that provides mobile data in 150+ countries. The mechanics are identical to any eSIM provider:

1. Purchase a plan on saily.com or in the Saily app
2. Receive a QR code by email
3. Scan the QR code in your phone's SIM settings
4. The eSIM profile installs in 30–60 seconds
5. At your destination: activate the eSIM profile and enable Data Roaming

Your primary SIM (physical) remains active throughout — you retain your regular phone number for calls and SMS while the eSIM handles data.

What makes Saily different from most eSIM providers: the built-in VPN layer, inherited from NordVPN's technology, which encrypts your connection automatically on unsecured public Wi-Fi networks. For travellers who regularly use hotel Wi-Fi, airport networks, or café hotspots, this is a meaningful differentiator — it adds a layer of security without requiring a separate VPN app or subscription.

Saily pricing: real numbers for 2026

Prices vary by destination and plan size. A representative selection:

Europe (single country plans)

Non-EU destinations

Europe regional plan

Saily's Europe plan covers 39+ countries simultaneously:

• 1 GB / 30 days: ~$5
• 3 GB / 30 days: ~$10
• 5 GB / 30 days: ~$15
• 10 GB / 30 days: ~$25

For multi-country European trips, the regional plan eliminates the need to buy separately per country — one plan activates across all 39 countries on the list.

Saily vs Airalo vs Yesim: the full comparison

Where Airalo wins

Maximum variety: Airalo sources plans from hundreds of local providers worldwide, producing the widest selection of options per country. If you want to compare five different Turkey plans at different price points and data quantities, Airalo offers that. Saily typically offers 3–4 options per destination.

Coverage depth: 200+ countries means Airalo covers destinations that Saily (150+) does not. For unusual destinations (Pacific Islands, Central Africa, Central Asia), Airalo is almost always the better option.

Established track record: Airalo launched in 2019 and has processed millions of eSIM purchases. The installation flow is extremely well-tested and the support team handles edge cases efficiently.

Where Saily wins

VPN inclusion: for travellers who regularly use public Wi-Fi (hotels, cafés, airports), the basic VPN layer adds meaningful security at no extra cost. If you would otherwise pay for a VPN subscription separately (~€5/month), Saily's VPN makes its effective price lower.

Brand trustworthiness for new eSIM users: Nord Security's reputation carries significant weight for first-time eSIM buyers who are uncertain about which provider to trust. The NordVPN brand recognition reduces hesitation.

Simplicity: fewer options per destination can be an advantage for travellers who find Airalo's extensive selection overwhelming. Saily presents 3–4 clearly labelled options and the decision is straightforward.

Price for common European destinations: for France, Germany, Italy, and Spain specifically, Saily often matches or slightly undercuts Airalo's pricing. The difference is small ($1–2) but real.

Where Yesim wins

Unlimited data plans: Yesim is the only major eSIM provider offering genuinely unlimited data plans in most countries. For remote workers, video call-heavy travellers, or anyone who streams content frequently, Yesim's unlimited plan (~$30/week) removes data anxiety entirely. Neither Saily nor Airalo offers this.

Strong regional plans: Yesim's multi-country regional plans are competitively priced and cover the most common European and Asian combinations.

The VPN feature: what it actually does

Saily's built-in VPN is worth understanding clearly, because "VPN included" can mean very different things.

What the Saily VPN does:

• Encrypts your data connection when using any network (including the eSIM itself)
• Protects against packet sniffing on public Wi-Fi (someone on the same network intercepting your data)
• Hides your browsing from the local network administrator
• Basic protection for banking apps, passwords, and sensitive communications on untrusted networks

What the Saily VPN does NOT do:

• It is not the full NordVPN client — it lacks threat protection (blocking malicious sites), dedicated IP addresses, obfuscated servers, or split tunnelling
• It does not unblock streaming services (Netflix, Hulu, BBC iPlayer) as a full VPN might
• It does not bypass country-level internet restrictions (like Turkey's social media restrictions or China's Great Firewall)

For most travel use cases: the Saily VPN is sufficient. If you're using hotel Wi-Fi to check your bank account or access work email, the encryption provided is meaningful protection. If you specifically need to unblock streaming services or bypass government internet restrictions, you need a full VPN product (NordVPN, ExpressVPN, etc.) in addition to or instead of Saily.

How to buy and install Saily

Step 1: Check eSIM compatibility

Your phone must support eSIM:

• iPhone: XS or newer (2018+). Dial *#06# — if EID appears, eSIM is supported
• Samsung Galaxy: S20 series and newer
• Google Pixel: 3 and newer
• Other Android: check Settings → Connections → SIM card manager for "Add eSIM" option

Step 2: Purchase your plan

Go to saily.com or download the Saily app. Select your destination, choose your plan size, and pay by card. You receive a QR code by email within seconds.

Step 3: Install at home (critical)

Install before departure — not at the airport, not after landing. Stable Wi-Fi at home is the correct environment.

iPhone:

1. Settings → Mobile Data → Add eSIM
2. Tap "Use QR Code"
3. Scan the QR from the email
4. Label it (e.g. "Saily Travel")
5. Keep it as secondary / inactive until needed

Android (Samsung):

1. Settings → Connections → SIM card manager → Add eSIM
2. Scan QR code
3. Confirm installation
4. Keep inactive until arrival

Step 4: Activate at your destination

When you land:

1. Go to SIM settings
2. Select the Saily eSIM profile
3. Set it as your data SIM
4. Enable Data Roaming on the Saily profile
5. Internet starts within 30–60 seconds

Step 5: Keep your primary SIM active

Your physical SIM stays active for calls, SMS, and bank verification codes. Set Data to Saily, Calls and SMS to your primary SIM. Both work simultaneously. Full installation guide: how to install an eSIM step by step.

The Turkey exception: buy before you land

If your trip includes Turkey — and this applies to Saily, Airalo, and Yesim equally — you must purchase and install your eSIM before arriving.

Since 2025, Turkish authorities have blocked access to major international eSIM provider websites from within Turkey. If you try to buy after landing in Istanbul or Antalya, the saily.com, airalo.com, and yesim.app websites simply do not load on Turkish mobile networks or local Wi-Fi.

The eSIM profile installed at home activates normally once you land — the block only affects the purchase/installation process, not the service itself.

When to choose which provider

Choose Saily if:

• You want a trusted brand (NordVPN ecosystem) for your first eSIM purchase
• You regularly use public Wi-Fi and want the built-in VPN protection
• Your destination is in Saily's 150+ country coverage
• You're travelling to common European destinations where Saily's pricing is competitive

Choose Airalo if:

• You want the maximum variety of plans per country
• You're travelling to an unusual or lesser-visited destination (Airalo's 200+ country coverage is broader)
• You want to compare multiple options from different local providers before deciding
• You've used Airalo before and have a positive track record

Choose Yesim if:

• You need unlimited data (remote work, frequent video calls, streaming)
• You're taking a multi-week or multi-continent trip where data usage is unpredictable
• You want the widest possible geographic coverage

The universal rule for all three: compare prices for your specific destination before buying. The difference is usually small ($1–3 for a standard 5 GB week's plan), but on a 5-country trip it adds up. Spend 5 minutes comparing all three on their websites before purchasing.

eSIM vs roaming: when does an eSIM actually make sense?

Within the EU (for EU residents): free roaming applies — your Romanian, German, or French mobile plan works across all 27 EU member states at no extra charge. An eSIM is usually not needed. Exception: if your plan has a small monthly data allowance and you'll be roaming for more than 2 weeks.

Outside the EU (UK, Turkey, USA, Asia, etc.): an eSIM is almost always significantly cheaper than carrier roaming. A UK eSIM for a week costs $10–15. UK carrier roaming from most European providers costs €3–7 per day. For a 7-day trip to London: eSIM $10–15 vs roaming €21–49. The eSIM wins.
