Seamless Japan Connectivity: Buy & Activate Your eSIM at the Airport or Anywhere for Instant Internet

For your first trip to Japan, everything you see will likely be new and exciting. However, you probably have concerns like the language barrier or navigating an unfamiliar environment. Specifically, worries about whether your smartphone will work in Japan and if communication charges will be high might be significant. Until now, common ways to stay connected in Japan included renting Pocket WiFi, purchasing a physical SIM card, or using international roaming. Pocket WiFi requires advance booking, can involve lengthy procedures at the airport, and adds the hassle of returning it, plus extra luggage. Physical SIM cards can be bought at airports, electronics stores, and convenience stores, but prices are often inflated at locations frequented by many tourists. International roaming tends to be very expensive.

eSIM is here to solve all those problems at once! For travelers with eSIM-compatible smartphones, using an eSIM is by far the best recommendation. When you buy from a local Japanese provider, the prices are more affordable, and you connect directly to Japan's reliable network, ensuring stable communication.

Ready to Use Upon Arrival! Why eSIM is Perfect for Your Trip to Japan

Many travelers arrive at Narita, Haneda, and Kansai Airports.
The shops selling SIM cards and renting Pocket WiFi are often very crowded. While there are SIM card vending machines, if you're short on time due to transfers or train schedules and can't buy a SIM card or rent Pocket WiFi, an eSIM allows you to easily purchase and start communicating.

Instant Purchase and Setup at the Airport

You can buy an eSIM at airport sales counters. After purchase, all you need to do is scan a QR code, so no complicated setup is required. As soon as you clear immigration, you can connect to the internet, post on social media, or look up directions with map apps, using your smartphone stress-free. Even if you're not at a Japanese airport, you can purchase an eSIM online, making it possible to buy and start communicating with an eSIM anytime, anywhere.

No Carrying, No Worries About Loss

Unlike Pocket WiFi, you won't have extra luggage or need to worry about charging. Since it's built into your smartphone, there's no risk of losing it, allowing you to enjoy sightseeing smartly.

Dual SIM Allows You to Keep Your Existing Number

Many eSIM-compatible smartphones feature "Dual SIM" functionality. This allows you to use your Japanese eSIM for data communication while keeping your home country's phone number.

From Airport Purchase to Setup! Connect in Simple Steps

eSIM sales counters are available in the arrival lobbies of major Japanese airports (such as Narita International Airport, Haneda Airport, Kansai International Airport, and Chubu Centrair International Airport).

The purchase and setup process is easy.

1. Head to the eSIM Sales Counter: Look for the eSIM sales location in the arrival lobby.
2. Present Your Passport and Select a Plan: Choose a plan that suits your desired data volume and validity period.
3. Payment: Credit card payment is accepted.
4. Scan the QR Code: Simply scan the provided QR code from your smartphone's settings screen to complete the setup!
5. Instant Internet Connection! You are now connected for communication in Japan.

Data-Only Means No Identity Verification Required!

Most eSIMs sold in Japan are plans specifically for data communication. Unfortunately, SIM cards and eSIMs that allow calls are not sold to travelers. Under Japanese law, data-only eSIMs and SIM cards generally do not require tedious identity verification procedures (such as presenting identification). You can start using them smoothly at airport counters with just a few simple pieces of information.

Even More Convenient! Online eSIM Supports Your Trip

The greatest appeal of eSIM is its ease and flexibility. While purchasing at the airport is convenient, online purchasing offers even more choices and convenience.

Purchase Anytime, Anywhere! No Worries If You Miss It at the Airport

If you forget to buy a SIM card at the airport upon arrival, or can't find the Pocket WiFi counter, don't worry. You can purchase an eSIM online anytime, from anywhere. Major Japanese airports offer free Wi-Fi services in arrival lobbies and other areas, so as long as you have a Wi-Fi environment, you can immediately purchase and set up an eSIM from your smartphone. This is a true lifesaver for travelers, as it can meet sudden communication needs at hotels, cafes, or even on trains.

Prepare Before You Arrive in Japan! Purchase Before Departure for Peace of Mind

If you're thinking, "I want to use the internet as soon as I arrive in Japan, but I don't want to rush around once I'm there," eSIM is perfect for you. You can purchase and set up an eSIM online using your home or airport Wi-Fi before you even depart for Japan. This means you'll be connected to the internet the moment you step off the plane. You can notify family and friends of your arrival, look up train transfers, and start your trip smoothly.

Use It Smartly and Comfortably! eSIM Tips You Should Know

Is Your Smartphone eSIM Compatible? Check If It's SIM-Unlocked!

To use an eSIM, your smartphone must be eSIM compatible. Most iPhone XS models and later, and many Android phones from Pixel 3 onwards, are compatible, but it's a good idea to check your smartphone's settings or the manufacturer's official website just to be sure. Smartphones purchased through a mobile carrier may be SIM-locked. If your phone is SIM-locked, you won't be able to use a Japanese eSIM, so before coming to Japan, contact your carrier to unlock your SIM or prepare a SIM-free smartphone.

Troubleshooting Tips

If you're having trouble setting up your eSIM or can't get data to work, try toggling your smartphone's airplane mode on/off or restarting it. If that doesn't solve the issue, contact the eSIM provider's support. Many companies offer English support.

How to Check if Your Smartphone Supports eSIM

There are several ways to verify if your smartphone can use eSIMs sold in Japan. You can check through EID or by accessing the settings on both iPhone and Android devices.

Checking EID via Your Phone (Simple Method)

EID (eSIM ID) is a unique identifier for devices that support eSIM. By checking the EID, you can confirm if eSIM is available for use.

Using the Phone App

Open the phone app on your device.
Enter *#06# and dial.
The EID will be displayed. This method works on both iPhone and Android smartphones. By following these steps, you can easily determine if your smartphone supports eSIMs available in Japan.

EID

A screen with info will appear. If your phone is eSIM-compatible, you'll see an EID number in the list.
It's not obvious on some phones, but the list is scrollable, so if you can't see EID, make sure you scroll all the way down. The EID number might also show as 'EID 2'.

Checking EID in Settings

For iPhone

Open the Settings App: Tap the "Settings" icon on your home screen.
Select General: Tap "General," then choose "About."
Check for Digital SIM: Look for an item labeled "Digital SIM" or "eSIM." If it’s displayed, your device supports eSIM.

For Android

Open the Settings App: Access the settings app on your smartphone.
Select Network & Internet: Tap "Network & Internet."
Check for Add SIM Options: Tap the "+" next to SIM and check if options like "Add eSIM" or "Add Plan" are displayed. If so, your device is eSIM-compatible.

What If the EID (eSIM ID) Does Not Appear?

If the EID does not appear, your device may not support eSIM. This is especially common in older models or certain Android devices. In such cases, refer to the device's user manual or the manufacturer's official website for confirmation.

Be aware that companies selling eSIMs may not provide accurate information about device compatibility if you do not have detailed model information. Therefore, it’s best to contact the company or manufacturer where you purchased your smartphone.
