International travel has become easier than ever, but staying connected abroad can still be surprisingly complicated. Traditional international roaming plans can be expensive, buying a local SIM card often takes time, and relying entirely on public Wi-Fi can be inconvenient and, in some situations, less secure.
This is where travel eSIM services have become increasingly popular. Instead of searching for a SIM card shop after landing at the airport, travelers can purchase a digital data plan before their trip and connect to a mobile network using an eSIM-compatible device.
One of the services making this process easier is Saily. Created by Nord Security, the company behind NordVPN, Saily offers prepaid eSIM data plans across more than 200 countries and regions. The service is designed for travelers who want a straightforward way to access mobile data without dealing with physical SIM cards or potentially expensive roaming charges.
But is Saily actually worth using? How easy is it to set up, what features does it offer, and who is it best suited for?
In this detailed Saily eSIM review, we’ll take a closer look at how the service works, its main features, setup process, advantages, possible limitations, and whether it could be the right choice for your next international trip.
What Is Saily?
Saily is a prepaid travel eSIM service that allows travelers to purchase mobile data for destinations around the world. Instead of inserting a physical SIM card into your phone, you download and install a digital SIM profile directly onto a compatible device.
The basic idea is simple. Before traveling, you choose your destination, select a data plan, install the eSIM, and prepare your phone for travel. Once you arrive at your destination and the plan activates, you can use mobile data without having to search for a local SIM card provider.
According to Saily, its service currently provides data plans in more than 200 destinations. The company also offers country-specific, regional, and other travel-oriented options depending on the destination and available plans.
Saily is particularly interesting because it combines travel connectivity with additional digital security features. Depending on the plan and available features, users can access tools such as ad blocking, web protection, and virtual location functionality within the app.
For travelers, this means Saily is trying to offer more than simply an internet connection. It aims to provide a convenient mobile connectivity experience that can be managed from one application.
What Is an eSIM and How Does It Work?
Before deciding whether Saily is worth buying, it helps to understand what an eSIM actually is.
An eSIM, or embedded SIM, is a digital SIM built into a compatible device. It performs many of the same functions as a traditional physical SIM card, but there is no small plastic card to insert or remove. Instead, the cellular plan is downloaded and activated digitally.
For international travelers, this can be extremely useful. You may be able to keep your regular SIM active for your primary number while using a separate travel eSIM for mobile data. The exact setup depends on your phone and the way you configure your cellular settings.
The main advantage is convenience. Imagine arriving in another country after a long flight. Instead of standing in a queue at an airport kiosk, comparing local SIM cards, or trying to understand unfamiliar registration requirements, you can potentially have your travel connectivity prepared before you leave home.
Of course, your device needs to support eSIM technology, and travelers should always check compatibility before purchasing a plan.
Saily explains that its eSIM can be installed through its app, with the service guiding users through the setup process. Once the eSIM and plan are properly configured, the plan can activate when you reach your destination or according to the activation terms of the purchased plan.
How Does Saily Work?
The Saily experience is designed to be relatively straightforward. You generally begin by selecting the country or region you plan to visit and choosing an available data plan that matches your trip.
After purchasing a plan, you download the Saily application and follow the setup instructions to install the eSIM on your compatible device. You may also need to adjust your phone’s mobile data and roaming settings according to the instructions provided for your plan.
Saily’s official guidance describes the process in three broad stages: choosing a plan, setting up the eSIM and enabling the required data settings, and then using the connection when the plan activates at the destination.
This is one of the biggest reasons eSIMs have become attractive for travelers. The preparation can happen before departure, which means you do not necessarily have to solve your connectivity problem after landing.
For example, if you are traveling from India to Europe, you can prepare your eSIM before boarding your flight. When you arrive, you can focus on finding your hotel, ordering transportation, checking maps, or contacting people online rather than immediately looking for a local SIM provider.
That convenience can be especially valuable for first-time international travelers.
Saily eSIM Coverage: Where Can You Use It?
Coverage is one of the most important factors when choosing any travel eSIM. A cheap plan is not useful if the service does not support your destination.
Saily offers plans for more than 200 countries and regions, covering a wide range of popular travel destinations around the world. Travelers can check available destinations and plans directly through Saily before purchasing.
This wide availability can be particularly useful for people who travel frequently or visit multiple countries. Instead of becoming familiar with a completely different local SIM provider in every country, travelers can manage their travel connectivity through one service.
However, it is important to remember that coverage availability and specific plan options can differ by destination. Network performance can also vary depending on the local mobile network, your location, device, and other conditions.
Therefore, before purchasing any eSIM plan, it is always a good idea to check the specific destination on Saily’s website or app and review the plan details carefully.
Setting Up Saily: Is It Easy for Beginners?
For many people, the biggest concern about eSIM technology is setup. Physical SIM cards are familiar—you simply insert one into your phone. A digital SIM can sound more complicated, especially for someone using an eSIM for the first time.
Fortunately, modern eSIM services are designed to make the process accessible to regular smartphone users.
With Saily, the process is managed primarily through the app. The general workflow involves purchasing a plan, installing the eSIM, and following the instructions shown on your device. Saily provides setup guidance for both iPhone and Android users.
Before installing an eSIM, make sure your device is unlocked and compatible with eSIM technology. You should also have an internet connection available during the initial installation because the digital SIM profile needs to be downloaded to your device.
Once the eSIM is installed, it is important to follow the instructions regarding mobile data selection and data roaming. Many travel eSIMs require roaming to be enabled for the travel eSIM in order to connect to their partner network.
This may sound confusing at first, but the setup process is generally much easier when you complete it calmly before your trip rather than trying to do it immediately after arriving in another country.
My recommendation for travelers is simple: install and configure your eSIM before leaving home, but follow the activation instructions for your specific plan carefully.
Why Use Saily Instead of International Roaming?
International roaming from your existing mobile carrier can be convenient because you do not need to install another SIM. However, convenience can sometimes come with higher costs or restrictions depending on your carrier and destination.
A prepaid travel eSIM gives you another option. Instead of using your home carrier’s roaming plan, you purchase a specific amount of travel data for your destination.
One advantage is predictability. With a prepaid plan, you generally know what you are paying for before the trip. This can make budgeting easier and reduce concerns about unexpected roaming charges.
Saily specifically positions its prepaid plans as an alternative to traditional roaming costs, allowing travelers to purchase data in advance and manage their plans through the app.
For a short vacation, the savings and convenience can make an eSIM a practical choice. For a longer trip, however, it is worth comparing the available Saily plan with local SIM card prices and your expected data usage.
There is no single solution that is cheapest for every traveler. Someone spending three days in another country may have very different connectivity needs from someone living abroad for six months.
Saily Data Plans: Choosing the Right Option
Choosing the right amount of data is one of the most important parts of buying a travel eSIM.
Your data needs depend heavily on how you use your phone. If you mainly use Google Maps, WhatsApp, email, ride-sharing apps, and occasional social media, you may not need an extremely large amount of data. On the other hand, uploading videos, streaming movies, joining video meetings, and using your phone as a hotspot can consume significantly more data.
Saily offers different data options, with availability varying depending on the destination and type of plan. Its website describes options ranging from smaller plans to larger or unlimited offerings in certain cases.
For most travelers, it makes sense to think about your actual usage rather than automatically buying the biggest plan.
A traveler on a relaxing holiday might spend most of the day exploring and only need data for maps and messaging. A digital nomad, on the other hand, might need significantly more data for work, video calls, file uploads, and hotspot usage.
If you are unsure, start by estimating how much mobile data you typically use at home. Then consider whether your travel behavior will increase or decrease that usage.
Remember that mobile data is often used more heavily during travel because navigation, translation, booking apps, and online research become essential throughout the day.
Saily’s Built-In Security Features
One area where Saily attempts to stand apart from many basic travel eSIM providers is digital security.
Travelers frequently connect to unfamiliar networks and public Wi-Fi while abroad. Although mobile data can offer an alternative to relying on public Wi-Fi, online privacy and security are still important.
Saily offers security-related features within its service, including an ad blocker, web protection, and virtual location functionality. The availability and exact behavior of these features should be checked within the app and for the applicable plan.
The ad blocker is designed to reduce certain intrusive advertisements through DNS-based filtering. This can potentially improve the browsing experience and may help reduce unnecessary data usage caused by advertising content.
Web protection is intended to help block access to known malicious websites and reduce tracking at the domain level. However, it is important to understand that no security feature can protect against every online threat. Saily itself notes limitations associated with DNS-based protection, including threats that do not rely on DNS resolution.
The virtual location feature provides another layer of privacy-oriented functionality by allowing users to choose from available virtual locations.
For travelers who care about online privacy, having these tools integrated into a travel connectivity service can be an attractive bonus.
Can You Keep Your Regular SIM While Using Saily?
One of the best things about eSIM technology is that many compatible smartphones support multiple cellular profiles.
This can allow travelers to keep their primary SIM or phone number while using an eSIM such as Saily for mobile data. Your exact options will depend on your device, carrier, and phone settings.
For example, you might keep your regular SIM available for receiving important messages while setting Saily as your primary source of mobile data during your trip.
However, you should be careful with your settings. If you leave mobile data roaming enabled on your home SIM, your regular carrier could potentially charge roaming fees depending on your plan.
Before traveling, check which SIM is selected for mobile data and review your carrier’s roaming settings.
This is a practical reason why travelers should spend a few minutes understanding their phone’s cellular settings before departure.
Does Saily Offer a Phone Number?
This is an area where travelers should pay close attention to the specific service and plan they are purchasing.
Saily’s current official information describes an optional add-on involving a US-based phone number and call and SMS functionality alongside compatible services, while some older help materials describe standard Saily eSIM plans as data-only. Product features can evolve, so travelers should always check the latest plan details in the Saily app or official website before purchasing.
For many travelers, data-only service is not a major problem. Apps such as WhatsApp, FaceTime, Telegram, and other internet-based communication platforms can be used through mobile data or Wi-Fi.
But if you specifically need traditional voice calls or SMS while traveling, do not assume every eSIM plan includes them. Always confirm the exact features of your chosen plan.
What Is Saily Ultra?
For frequent travelers, Saily also offers a premium option called Saily Ultra.
According to Saily, the Ultra plan combines international connectivity with additional travel and digital security benefits. The official Ultra page describes coverage in 121+ destinations, a monthly allowance of high-speed data followed by unlimited data at reduced speeds, along with features such as premium security tools and selected travel benefits.
This type of plan is likely more relevant for people who travel frequently, move between countries, or want a subscription-style service rather than repeatedly purchasing individual data packages.
For an occasional traveler taking a short holiday, a standard prepaid plan may be a more sensible option. For a frequent business traveler or someone constantly moving between international destinations, a premium plan may offer additional convenience.
As with any subscription, it is important to review the current price, renewal terms, included destinations, and cancellation policy before signing up.
What Are the Main Advantages of Saily?
The biggest advantage of Saily is convenience.
You can prepare your connectivity before traveling rather than searching for a local SIM after arriving. For many travelers, that alone is enough to make an eSIM worthwhile.
Saily also offers broad destination coverage, with plans available in more than 200 countries and regions. This makes it a flexible option for international travel and multi-country trips.
Another major benefit is the ability to manage your travel data digitally. There is no tiny plastic SIM card to lose, no need to open your phone’s SIM tray, and no need to physically replace your existing SIM.
The security-focused features are another notable advantage. The availability of tools such as ad blocking and web protection gives Saily a feature set that goes beyond basic mobile connectivity.
Finally, Saily provides 24/7 customer support according to its official support information. That can be particularly valuable when you are in another country and need help with connectivity outside normal business hours.
Are There Any Disadvantages?
No travel eSIM service is perfect for every situation, and Saily is no exception.
The first limitation is device compatibility. If your smartphone does not support eSIM technology, you will not be able to use an eSIM service.
The second consideration is that mobile network quality depends on local coverage. An eSIM provider can make purchasing and managing data easier, but actual signal strength can still vary based on the country, city, building, and local network conditions.
Pricing is another factor. An eSIM can be convenient, but convenience does not always mean it will be the cheapest possible option. In some destinations, a local physical SIM may offer more data for the price. Travelers staying for an extended period should compare available options.
Finally, users should carefully check the details of individual plans. Data limits, validity periods, supported countries, speed conditions, and other terms may vary.
The best approach is to choose the plan based on your specific trip rather than assuming that one plan is perfect for everyone.
Who Should Use Saily?
Saily can be a particularly good option for tourists who want to get connected quickly after arriving in another country.
It may also work well for business travelers who depend on reliable access to email, maps, messaging, and online services while moving between destinations.
Digital professionals who travel internationally may appreciate the ability to manage data plans through an app and avoid constantly buying physical SIM cards.
First-time international travelers can also benefit from the simplicity of preparing their mobile data before departure. Having internet access soon after landing can make a major difference when you need directions, transportation, hotel information, translation tools, or access to important travel documents.
On the other hand, someone planning to live in a country for a very long period may want to compare Saily with long-term local mobile contracts or local prepaid options.
Tips for Getting the Best Experience With Saily
The most important tip is to check phone compatibility before buying a plan. Don’t wait until the day before your flight to discover that your device is carrier-locked or does not support eSIM.
Install the Saily app and complete as much of the setup process as possible before traveling. This gives you time to resolve any issues while you still have access to your normal connection.
Keep your confirmation details and account information accessible. If possible, make sure you know how to contact support before you leave.
You should also monitor your data usage, especially if you have purchased a limited plan. Streaming high-definition video and uploading large files can use data much faster than expected.
Finally, always review the specific instructions for your destination and plan. International connectivity involves different networks and settings, and the details matter.
Is Saily Legitimate?
Yes. Saily is an established eSIM service associated with Nord Security, the company behind NordVPN. Saily’s official help center describes it as a prepaid eSIM service for international mobile data, and the company provides support resources and information about its services online.
As with any online service, however, travelers should purchase plans only through official channels and carefully review plan details before paying.
You can explore destinations and current options directly through the official Saily website.
Final Verdict: Is Saily Worth It for International Travel?
For many international travelers, Saily is worth considering.
Its biggest strengths are convenience, wide destination coverage, digital eSIM setup, and additional security-oriented features. The ability to arrange your mobile connectivity before leaving home can make international travel significantly less stressful.
Instead of arriving in a new country and immediately worrying about finding a SIM card, you can focus on your journey. Open your maps, book a ride, contact friends or family online, and access important travel information with a prepared mobile data connection.
Saily may be especially useful for short-term travelers, frequent flyers, business travelers, and people visiting multiple destinations. The service’s coverage across more than 200 countries and regions gives it flexibility for a wide variety of trips.
However, the best plan for you will always depend on your destination, budget, device compatibility, and data requirements. If price is your only priority, comparing local SIM options may still be worthwhile. But if you value convenience, easy setup, and the ability to manage your travel connectivity digitally, Saily offers a compelling option.
Our recommendation
Before your next international trip, check whether your phone supports eSIM technology, review the available plans for your destination, and estimate how much data you realistically need. If Saily offers a plan that matches your travel requirements, setting it up before departure could save you time and help you stay connected from the moment your journey begins.
Traveling should be about exploring new places—not searching for a SIM card after landing. With an eSIM service like Saily, staying connected can become one less thing to worry about.
