What is an eSIM in Japan?
- ・eSIM?
- ・Differences Between eSIM and SIM Cards
What is an eSIM?
An eSIM is a service that allows you to download data to your smartphone and use local network services. It works by storing data within the smartphone itself, eliminating the need for a physical card and the hassle of swapping it.
This is a new technology that is gaining popularity worldwide. With an eSIM, you can manage internet connectivity through your smartphone alone, which helps keep your travel luggage compact
There is a wide range of data capacities and usage durations available, allowing you to choose a plan that perfectly fits your schedule. Additionally, with its affordable pricing, it is recommended for those who want to minimize communication costs during their stay.
Differences Between eSIM and SIM Cards
eSIM | SIMカード | |
---|---|---|
SIM card swapping | Not required | Required |
Activation time | As short as the same day | 3-5 days |
Compatible devices | Not available on some models | Works with most models |
Cancellation after application | Not possible | Possible |
Unlike SIM cards, eSIMs do not require physical card swapping, which reduces the risk of damage or loss during exchange.
Additionally, eSIMs can be activated as quickly as 5 minutes after application. If you run out of data, you can easily purchase more as long as you have an internet connection.
However, eSIMs are not supported on some devices. As a new technology, most smartphones released before 2018 are not compatible.
Advantages of Using eSIM for Traveling in Japan
- ・Can be purchased before your trip and used immediately upon arrival
- ・Generally cheaper than other communication methods
- ・Can be used in conjunction with your regular SIM card
- ・No risk of loss or damage
Can be purchased before your trip and used immediately upon arrival
eSIM can be purchased in advance via the web. You can download and set it up beforehand, so you can start using Japan’s mobile network immediately upon arrival at the airport.
With a SIM card, you need to find a shop at the airport or in town. Additionally, you won’t have internet access until you switch the card, which can be inconvenient.
With an eSIM, everything is completed online. You can start using it immediately after purchase, making it convenient if you need it at the last minute before departure or upon arrival.
Generally cheaper than other communication methods
Days and Data Capacity | Price | |
---|---|---|
Holafly (eSIM) |
10 days Unlimited data |
$36.90 |
Japan Wireless (Pocket WiFi) |
$69.0 |
eSIM is cheaper than other communication methods! When compared to pocket WiFi, the difference is about double.
Additionally, eSIMs are prepaid, so there are no additional charges. The pricing structure is straightforward, making it easier to budget your travel expenses.
If you want to keep communication costs as low as possible during your trip to Japan, opt for an eSIM!
Can be used alongside your regular SIM card
eSIM can be used alongside your regular SIM card. It allows you to switch networks without removing the card, which is very convenient.
After returning home, you can easily switch back to your original mobile network with a simple operation. This minimizes the time you are without internet.
No Worries About Loss or Damage
eSIM uses data downloaded to your device, so there is no risk of loss or damage.
Physical SIM cards are small and can be easily misplaced during exchange. If you lose the card while traveling, you will need to go through a reissue process.
Additionally, losing a rented pocket WiFi device can result in significant compensation fees. With an eSIM, you only need to manage your smartphone, making your travels lighter and more convenient.

For Android devices, even models released around the same time may not support eSIM depending on the manufacturer.

Cannot Be Used on Devices with SIM Locks
SIM cards cannot be used on devices with SIM locks.
A SIM lock is a restriction imposed by mobile carriers that prevents the use of SIM cards from other providers.
If your device is locked, contact your carrier to have the lock removed.
No Cancellation After Application
eSIMs cannot be canceled after application. They are issued immediately upon order, and since they are digital products, there is no physical item to return.
If you purchase the wrong plan, you will need to reorder. Be sure to carefully check the country, duration, and data capacity before applying.

4 Things to Watch Out for When Setting Up eSIM
- ①Check if SIM Lock is Removed
- ②Printing or Another Device Needed to Scan QR Code
- ③Do Not Delete eSIM Once Activated
- ④Registered eSIM Cannot Be Used on Other Devices
①Check if SIM Lock is Removed
Before setting up, make sure that SIM lock is removed. SIM lock is a feature that restricts the device from using SIM cards from carriers other than the one it was originally locked to.
If your device is SIM-locked, contact your carrier to have it removed.
②Printing or Another Device Needed to Scan QR Code
To use an eSIM, you’ll need to scan the QR code provided for the product using your smartphone’s camera. Make sure to print the code beforehand or display it on another device.
Additionally, many recent products now offer the option to manually enter the details. For iPhones running iOS 17.4 or later, you can also install the eSIM using a QR code image saved in your Photos app.
③Do Not Delete eSIM Once Activated
Do not delete an eSIM once it has been activated. Deleting it will invalidate the QR code.
If you encounter any issues during setup, contact the support center of the purchased eSIM instead of deleting the eSIM.
④Registered eSIM Cannot Be Used on Other Devices
A registered eSIM cannot be transferred to another device. If you accidentally download it to a different smartphone, you’ll need to purchase a new eSIM.
To avoid extra expenses, ensure you are setting up the eSIM on the correct device, especially if you own multiple smartphones.

Using Prepaid SIM Cards in Japan
Features of Prepaid SIM:
- ・Internet communication fees are low
- ・Usable with smartphones that do not support eSIM
- ・Requires purchasing a SIM card through online shopping or at the airport
- ・Configuration is necessary after inserting the SIM card
If you buy a prepaid SIM card, you can use Japan’s internet network simply by inserting it into your smartphone. The usage fees are low, and it’s a benefit that it can be used with smartphones that do not support eSIM.
You can purchase it not only from online stores but also at Japanese airports and electronics retailers. Recently, many airports have installed vending machines for SIM cards, making them available 24/7.
However, you need to swap and store the SIM card during your trip. Since the card is small, there is a high risk of damage or loss.
Using Rental WiFi
Features of Rental WiFi
- ・Can be shared with multiple people
- ・Pick up and return can be done at the airport
- ・Adds to the amount of luggage you need to carry during your trip
- ・Late fees apply if returned after the deadline
If you’re traveling with multiple people, rental WiFi is recommended! The cost is slightly higher, but it provides stable connectivity even when connecting multiple devices.
You can pick up and return the device at the airport. It’s easy to use—just enter the ID and password on your smartphone.
However, it does mean you’ll have more luggage to carry during your trip. Also, there are late fees if you return the device after the deadline, so be sure to check the dates and procedures in advance.
Using Free WiFi in Japan
Features of Free WiFi in Japan
- ・Provides free internet access
- ・Stops working when you move away from the WiFi spot
- ・Connection can be unstable or unexpectedly interrupted
- ・Risk of personal information being exposed to third parties
The advantage of free WiFi is that it provides internet access at no cost. In Japan, it is available in various places such as airports, restaurants, and hotels.
However, in areas outside major cities, there may be limited WiFi availability. Additionally, the connection can be unstable and prone to interruptions.
There are also security risks. Since many people use the same free WiFi network, there is a possibility that data could be stolen by malicious individuals.

Frequently Asked Questions About eSIMs in Japan
Can eSIM be used with any smartphone?
A.
eSIM requires a compatible smartphone or tablet. Additionally, it cannot be used with devices that have SIM locks.
There might be cases where your smartphone does not work if it is not compatible with Japanese frequency bands. Frequency bands refer to the classification of radio waves used for internet communication; if your device does not support these bands, it won’t be able to catch the signal.
Smartphones from global manufacturers like iPhone and Google Pixel generally have no issues. However, if you are using a domestically produced device, you should check the supported frequency bands in advance.
What should I do if I use up the data or reach the expiration date of my eSIM?
A.
How to handle running out of data or reaching the expiration date varies by eSIM provider. Most services will stop communication as soon as the data is used up, so you will need to purchase a new eSIM.
However, some products allow for continued usage at a reduced speed even after the data is exhausted, as long as it is within the validity period.
You can purchase a new eSIM quickly as long as you have an internet connection. If you need to buy one while you’re on-site, connect to free WiFi to place the order.
Are there unlimited data services available?
A.
If you want an eSIM with unlimited data, “Holafly” is recommended.
You can purchase it starting from 5.9 USD per day, with options available for up to 90 days. It’s suitable for those who use the internet frequently while traveling.
Can I make voice calls with a data-only eSIM?
A.
Even with a data-only eSIM, voice calls over the internet are possible using services like LINE and Skype.
However, since these calls use the internet connection, they consume data. For example, a 10-minute voice call on LINE uses about 3 MB of data.
Additionally, many reservations, such as those for restaurants, can be made online, so there are often few situations where you need a phone number.
