Is the Internet Connected? Saily Reviews and Feedback
We will present both positive and negative reviews of the Saily eSIM.
Positive Reviews
Here are four positive reviews for the Saily eSIM.
Reliable Support and Cancellation Process - Used Without Issues
★★★★☆
Used it on Android. Installed it for use in Spain and Turkey.
Followed the Japanese tutorial and set it up smoothly.
I thought it would work once I turned on mobile data, roaming, and SIM, but it didn’t. The cause was the APN settings.
Saily provides chat support through help, and even though I was a beginner, I was able to connect. Once it was connected, I had no issues using it.
I was also able to cancel a wrong purchase for a Turkish plan without any problems. The quick response and ability to communicate in Japanese was great.
If it wasn’t for the APN setup hassle, it would have been 5 stars.

Connected Seamlessly in the UK
★★★★★
It worked in the UK.
It wasn’t the cheapest, but since it’s provided by NordVPN, I prioritized reliability.
When I arrived at Heathrow Airport, I was nervous because I couldn’t connect right away, but after waiting a bit, I managed to connect successfully.
The mobile signal in the UK is very inconsistent, and I think I would have been offline during the flight.
If you complete the setup properly, it should work without any issues.

No Issues Using It for the First Time
★★★★★
Used it in Malaysia!
It was my first time using eSIM, and I was nervous, but LTE worked without issues.
I used Google Maps, search engines, and Pokémon GO, and 1GB was enough for the first two to three days!
(This was also because I stayed in places with Wi-Fi.)
(Source: App Store)
Worked Easily and Conveniently in Indonesia
Negative Reviews
Here are three negative reviews for the Saily eSIM.
Didn’t Work at All in South Korea
★☆☆☆☆
Didn’t work at all in South Korea. The support was poor, and I couldn’t do anything for three days.
(Source: Google Play)
Used It in Thailand, but Slow Internet Speed
★☆☆☆☆
Used it in Thailand, but it was too slow.
My wife was using another eSIM, which worked fine, but I had a frustrating trip with Saily. Very disappointing.
(Source: App Store)
Purchased Smoothly but Internet Was Slow
★☆☆☆☆
It was slow in Japan.
The purchase and installation were smooth, but it took 20-30 seconds to open an image, making it unusable. Since I had used more than 1% of the data, a refund wasn’t possible. I do not recommend it.
(Source: App Store)
Summary of Reviews and Feedback
Many positive reviews mentioned that the connection worked well even at the destination, while there were also some reviews mentioning that the connection speed was slow.
Most eSIM services, including those offered by many companies, operate through data roaming.
Data roaming involves connecting to the network of the country you're visiting by first routing through another country's telecommunications provider. This process can sometimes cause delays in communication.
When delays increase, they can affect internet speeds, making it harder to maintain a stable connection. This issue is not exclusive to Saily.
Saily offers 24/7 Japanese language support, which is great for receiving assistance without worrying about time zone differences!
While there have been complaints about slow responses, this can sometimes happen due to chat support, which might cause delays.
However, there were also reviews mentioning that issues were resolved quickly, and that the support team is helpful when dealing with problems abroad.

Saily's advantages include:
Advantages of Saily
- Get Internet Access Without SIM Swaps, Contracts, or Registrations
- Easy eSIM Setup with the Dedicated App
- Supports Over 200 Countries! No Need to Search for Wi-Fi Spots Locally
- The Operating Company is a Major Enterprise, Offering High Reliability and Security
Let’s dive into each of these features in more detail.
Get Internet Access Without SIM Swaps, Contracts, or Registrations
eSIM is different from traditional SIM cards in that there is no need to swap SIM cards, so you can get internet connectivity at your travel destination with just smartphone settings.
Also, unlike contracts with domestic mobile carriers, there is no need to register for a new account as long as you have a Google or Apple account.
With pocket Wi-Fi, although rentals are common, you have to go through the rental and return process, and you need to carry it with you at all times, which adds to your luggage.
The advantage of eSIM is that it eliminates these hassles, and the simplicity of Saily’s service is one of the key reasons to use it.
Easy eSIM Setup with the Dedicated App
When it comes to eSIMs for travel to Japan, installing a new eSIM for each trip is often required, which can feel a bit tedious.
However, with Saily, once you install the eSIM on your smartphone, all you need to do for each future trip to Japan is purchase the required data plan for your destination, making it much easier for subsequent uses.
You can easily check your remaining data and remaining days from the app. Plus, if you face any issues such as inability to access the internet in Japan, you can contact the support center directly within the app, making it highly convenient. This is particularly recommended for first-time users.
Supports Over 200 Countries! No Need to Search for Wi-Fi Spots Locally
Saily offers data plans for over 200 countries and regions.
Even if your destination is a lesser-known country, you should be able to find a plan for the country you're visiting.
Since you can use your regular smartphone to access the internet in Japan, there’s no need to hunt for Wi-Fi hotspots in Japan.
Additionally, while the data and usage day plans vary by country and region, there are options ranging from 1GB plans for light users to up to 100GB for heavy users.
Saily stands out, especially for its affordable prices on small data plans, making it an excellent choice for those who don't use much data frequently.
The Operating Company is a Major Enterprise, Offering High Reliability and Security
One of the most notable features of Saily is that it is operated by a major enterprise renowned worldwide for its security.
The Nord VPN service, which is essential for internet security, is the development source, providing high reliability and ensuring a safe and secure service experience.
When traveling to unfamiliar destinations, it's important to avoid any issues, and choosing an eSIM service from a trusted company is essential for peace of mind.
The pricing is not expensive, and the service is available at an affordable price, making it especially recommended for those who are using eSIM for the first time or prefer to purchase from a highly reliable company.
Disadvantages of Saily eSIM Based on Reviews
The disadvantages of Saily are as follows:
Disadvantages of Saily
- You cannot use the service unless you have a smartphone compatible with eSIM
- The data-only plan does not include voice calls
- In some areas, the internet speed may decrease
We will explain each of these points in detail.
You Can’t Use the Service Without a Smartphone Compatible with eSIM
Since Saily is an eSIM service, the device you want to use must be compatible with eSIM.
While most of the latest models support eSIM, older devices may not be compatible.
Therefore, before purchasing the service, make sure to check if your device supports eSIM!
No Voice Call Service with the Data-Only Plan
Saily only offers data-only plans, meaning there is currently no plan available with a phone number or SMS service for use in Japan.
eSIM plans with phone numbers available for use in Japan are already rare, but if you need to make calls or send/receive SMS in Japan, it’s recommended to use it alongside your regular mobile carrier’s SIM card.
Since your regular SIM card is typically not removed from your smartphone, you can use it as a dual-line system.
If you don't mind not receiving SMS, you can still use voice services via apps in Japan, as long as you have an internet connection, so feel free to take advantage of it!
Communication Speeds May Decrease in Certain Areas
As mentioned in reviews, communication speeds may slow down depending on the area or time of day.
Like most eSIM services, Saily operates on "data roaming" communication.
Data roaming connects to the local network via another country's telecom provider. This can cause delays, impacting internet speeds.
When using eSIM, it’s important to be prepared for possible connectivity issues.
If slow speeds are a concern, consider using eSIMs from different telecom providers than your travel companions or selecting an eSIM that allows you to use multiple networks!
