Saily eSIM Avis 2026: Is Saily eSIM reliable?

The Saily eSIM is a digital SIM card for travelers, offered by Nord Security, the company best known for its NordVPN service. An eSIM (embedded SIM) replaces a physical SIM card: it's directly integrated into your device and lets you access the Internet without having to change cards for each country you visit, simply by installing a profile in the dedicated application.

With Saily, you can purchase and activate prepaid data packages for over 200 destinations from the app or website, then easily manage them on your compatible smartphone. This avoids high roaming charges and the search for a local SIM card as soon as you land.

Saily eSIM is based on technology eSIM, i.e. a digital SIM integrated directly into your device, enabling you to connect to the Internet without inserting a physical SIM card. It works just like a conventional SIM card: it identifies your device to a mobile network and gives you access to 4G/5G data according to the plan you choose.

Once activated, the Saily eSIM automatically connects you to the local mobile network so you can surf the web, use your applications and stay online during your stay, without having to change your physical SIM card.

To use a eSIM Saily, it's not enough to have the application: your device must also support eSIM technology and be unlocked for any operator (i.e. not blocked by a mobile operator). Without this compatibility, Saily eSIM cannot be installed or activated.

Compatible device types

The majority of modern smartphones from the major brandsare eSIM-compatible: the iPhone from the iPhone XS (including the 11, 12, 13, 14, 15 and 16 series) all support eSIM, as do many recent Android models from Samsung, Google, Xiaomi, Huawei, Motorola, etc., equipped with eSIM technology.

Important: some devices sold in certain regions (e.g. mainland China)may not support eSIM, even if they are the correct model, so check with the specific model.

How do you check if your phone supports eSIM?

here's a instant verification tool to help you:

Here are three concrete benefits of using an eSIM when traveling, benefits you'll also get with an eSIM like the one offered by Saily:

1) Easier than with a physical SIM card

ESIM is entirely digital: it is installed via a downloaded profile or QR code, without the need to insert a plastic SIM card. This allows you to activate your plan directly from your devicewithout any hardware manipulation.

2) Fast activation and connection abroad

An eSIM allows you to purchase and activate your package, before or as soon as you arrive at your destination, making your journey smoother. You don't have to look for a local store for a SIM card, nor suffer the high roaming charges of your usual operator.

3) Flexibility of use on a single device

ESIM technology often allows you to manage several profiles or packages on a single smartphone (main line + travel data line, for example). Depending on the model, you may even have several eSIMs active in parallel.

Although Saily eSIM offers a practical solution for staying connected while traveling, several limitations and weak points recur in user feedback or comparative analyses:

1) ❌ No unlimited package or long data periods

Unlike some of our competitors' plans, which offer really unlimited plans or plans that are valid for a very long time, Saily plans are often limited in terms of data quantity or duration, which can be restrictive for extended stays or intensive use.

2) ❌ Connection quality varies by zone

According to some user reviews and tests, connection quality can vary from country to country or zone to zone (rural areas, less efficient local networks), which isn't always ideal if you're counting on a constant connection everywhere.

3) ❌ Customer service not always easily accessible

Some reviews mention a difficulty reaching a live advisoror getting quick assistance outside of the in-app help. This can be frustrating if you encounter a problem while traveling.

4) ❌ Price structure sometimes considered average

On forums and user feedback, the price is sometimes considered "average" compared to other eSIM, with discounts or promo codes necessary to make the package truly competitive.

Prices for Saily eSIMs vary depending on the destination, the amount of data and the validity periodof the plan you choose. Here's an overview of the main plan categories available to give you a clear idea of the prices charged:

Single country packages

These packages allow you to use data in a specific country, ideal for short stays or vacations.

✅ Advantage: simple and generally very affordable for a single country.

❌ Disadvantage: limited data or more expensive if you need a lot of data.

Global packages (multi-country)

Global plans cover several countries around the world, ideal if you're traveling to different destinations.

✅ Advantage: a single plan for several countries without having to change eSIMs.

❌ Disadvantage: higher initial price, especially for large amounts of data or long durations.

Regional packages

Depending on the offers available, Saily sometimes offers plans for specific regions (Asia, Europe, etc.), often at intermediate rates between country and global options. For example, some plans for Asia and Oceania start at around $4.99 for 1 GB.

✅ Advantage: good compromise if you stay within a limited geographical area.

❌ Disadvantage: less coverage than a global package.
