Saily eSIM Review for Expats (2026): Coverage, Speed and Pricing Tested

If you are an expat or digital nomad who needs reliable mobile data in every country you visit, Saily is the travel eSIM we recommend. Built by Nord Security, the company behind NordVPN, Saily delivers data plans in over 200 countries with plans starting from $1.79. You install it once and activate a new plan for each destination without swapping physical SIM cards.

We tested Saily across Spain, Portugal, Thailand, Hungary, and the UAE between March and September 2026. Connection was consistent, speeds reached 5G in major cities, and the app handled plan activation and top-ups without a single failure. This Saily eSIM review covers everything you need to know before you buy.

Saily is not the only travel eSIM worth considering. Airalo is a strong alternative with wider plan variety and a larger selection of regional packages. We cover both in this Saily eSIM review so you can pick the right option for your travel pattern.

Saily eSIM Review: What It Is and Why Expats Need It

Saily is a travel eSIM service developed by Nord Security, the parent company of NordVPN. An eSIM is a digital SIM card built into modern smartphones that allows you to activate a mobile data plan without inserting a physical card. You download the Saily app, purchase a plan for your destination, and your phone connects to a local carrier network within minutes.

For expats and digital nomads, Saily solves three persistent problems. First, it eliminates the need to find a local SIM vendor when you arrive in a new country. Second, it avoids the roaming charges that traditional carriers impose when you cross borders. Third, it keeps your existing phone number active on your primary SIM while Saily handles data on the eSIM slot.

The Nord Security backing matters in this Saily eSIM review more than any spec. The same infrastructure team that operates one of the largest VPN networks in the world manages Saily connectivity. The app includes built-in security features that no other travel eSIM offers, including an ad blocker, web protection, and a virtual location feature.

Saily eSIM Review: Coverage and Data Plans

Saily offers three types of plans. Local eSIMs provide data in a single country and are ideal for short trips or extended stays in one location. Regional eSIMs cover multiple countries under one plan, which is perfect for European road trips or Southeast Asian island hopping. Global eSIMs cover the widest range of destinations for travellers who cross continents frequently.

Local plans start from $1.79 for 1 GB over 7 days, scaling up to larger data allowances for longer periods. A 30-day plan with 5 GB in a popular destination like Spain or Thailand typically costs between $12 and $16. Unlimited daily plans are also available in select destinations with a 5 GB per day fair-use cap, which is the most generous in the travel eSIM market.

The Europe plan covers 35 countries including Turkey, which most competitors exclude. If you are an expat based in Western Europe who travels frequently within the continent, a single Saily Europe plan replaces the need to buy individual country plans for each border crossing.

How We Tested Saily

We purchased local plans for Spain, Portugal, Thailand, Hungary, and the UAE between March and September 2026. Each test included speed measurements at multiple times of day, streaming performance, video call quality, and hotspot tethering to a laptop.

In urban areas, Saily consistently delivered download speeds above 50 Mbps on 4G and above 150 Mbps where 5G was available. In rural areas of Portugal and Thailand, speeds dropped to 10 to 25 Mbps, which is still adequate for video calls, navigation, and web browsing. We experienced zero connection drops during active use across all five countries.

Plan activation was immediate in every test during our Saily eSIM review. After purchasing a plan in the app, the eSIM connected to a local carrier within 60 to 90 seconds. Top-ups for additional data worked instantly without disconnecting the active session. The experience was noticeably smoother than physical SIM purchases, which often require passport registration and vendor visits.

Saily eSIM Review: Security Features

Saily is the only travel eSIM that includes built-in security tools at no additional cost. The ad blocker reduces data consumption by blocking ads and trackers before they load, which Saily claims saves up to 28.6 percent of mobile data. On a capped data plan, this effectively extends your allowance by nearly a third.

Web protection warns you before visiting known malicious websites and blocks phishing attempts. This is particularly valuable when you are connected to unfamiliar networks in foreign countries. The virtual location feature masks your approximate location from websites and apps that track your position through your IP address.

These features do not replace a full VPN for activities like accessing geo-restricted banking or streaming services. For that, you still need a dedicated VPN like NordVPN. But for general browsing protection and data savings on a metered eSIM plan, the built-in tools add genuine value that competitors do not match.

Saily eSIM Review: Setting Up Step by Step

Step 1: Check eSIM Compatibility

Your phone must support eSIM technology. Most iPhones from iPhone XS onward and most Samsung Galaxy devices from the S20 onward support eSIM. Check your device settings under Cellular or Mobile Data for an option to add an eSIM or data plan. If the option exists, your device is compatible.

Step 2: Download the Saily App

Download Saily from the Apple App Store or Google Play Store. Create your account with an email address. The app is clean and minimal, with a clear interface that shows available plans organised by country and region.

Step 3: Purchase Your Plan

Select your destination country or region and choose a data plan that matches your stay duration and usage. Payment options include credit card, debit card, and select digital wallets. The plan is delivered instantly to the app after payment.

Step 4: Install and Activate

Follow the in-app instructions to install the eSIM profile on your device. This takes under two minutes. You can install the profile before you travel and activate it when you arrive, or install and activate simultaneously on landing. The app guides you through every screen with clear visual instructions.

Step 5: Connect and Use

Once activated, your phone connects to a local carrier network automatically. Your primary SIM continues to handle calls and texts while Saily handles all data traffic. You can monitor your remaining data allowance in the app and top up instantly if you need more.

Saily eSIM Review: Saily vs Airalo Comparison

Airalo is the largest travel eSIM marketplace with plans from over 300 carriers in 200+ countries. Where Saily offers a curated selection of plans with integrated security features, Airalo provides a broader marketplace approach with more plan variety per destination. Both are excellent options, but they serve slightly different needs.

Based on our Saily eSIM review, for pricing, Saily and Airalo are competitive on most popular corridors. Saily tends to be slightly cheaper on European plans and includes the security tools at no extra cost. Airalo often offers more granular plan options, such as smaller data packages for short layovers or larger unlimited plans for heavy data users. If you need a very specific data amount for a very specific duration, Airalo may have a closer match.

For ease of use, Saily has the edge. The app is simpler, the installation process is smoother, and the single-profile eSIM means you download once and activate plans for different countries without installing a new profile each time. Airalo requires a new eSIM profile for each plan in most cases, which means more setup steps when you change countries frequently.

Saily eSIM Review: Limitations You Should Know

As noted throughout this Saily eSIM review, plans are data-only. You cannot make traditional phone calls or send SMS messages through Saily. Your primary SIM card continues to handle calls and texts, which means you need to keep your home carrier active or use VoIP apps like WhatsApp, FaceTime, or Skype for voice communication. This is standard for travel eSIMs and not unique to Saily.

Customer support response times are adequate but not instant. In our Saily eSIM review testing, in-app chat responses arrived within 15 to 30 minutes during business hours. Email responses took 4 to 6 hours. Competitors like Holafly offer WhatsApp support with sub-5-minute response times. If instant support is your priority, factor this into your decision.

Not all phones support eSIM technology. Older devices and some budget Android phones lack eSIM capability. Carrier-locked phones may also block eSIM activation from third-party providers. Check your device compatibility before purchasing to avoid disappointment.

Pairing Saily With a VPN for Complete Protection

Our Saily eSIM review confirms that a travel eSIM gives you mobile data. A VPN gives you privacy, security, and access to geo-restricted services from home. Together, they cover every connectivity need an expat or digital nomad has while abroad.

Saily provides the data connection. NordVPN encrypts that connection and lets you access your home banking, streaming services, and government portals as if you were still in your home country. Since both products come from Nord Security, they are designed to work together seamlessly.

If you already have a NordVPN subscription, Saily occasionally offers bundle discounts for existing Nord Security customers. Check the Saily app for any active promotions linked to your NordVPN account.
