Prepare for an Adventure in Japan! Whether it’s visiting ancient temples or indulging in delicious ramen, having a stable internet connection is absolutely essential. To meet the needs of modern travelers, eSIM has become a popular choice. Compared to traditional physical SIM cards, eSIM is compact and convenient, making it highly favored by tourists.

What is eSIM?

eSIM eliminates the hassle of switching SIM cards. It acts as a magical key for your phone, effortlessly unlocking a new realm of communication. While traditional SIM cards require physical swapping when changing carriers, eSIM serves as a convenient express lane for your device. Simply reconnect to the new carrier network, download the new eSIM in seconds, and you’re good to go—no physical cards needed!

This isn’t just technology for tech enthusiasts; eSIM is an invaluable companion for every travel enthusiast. Imagine arriving at a Japanese airport without worrying about finding a SIM card slot. With just a few settings, your phone can seamlessly connect to Japan’s network. Plus, you don’t need to remove your home country’s physical SIM card, allowing you to answer international work calls anytime. eSIM makes your travels more comfortable and liberating!

Why Recommend eSIM for Traveling to Japan

We’ve introduced eSIM services, now let’s delve into why eSIM is a top choice for playing, traveling, or suddenly returning home in Japan. Here are the three highlights we recommend:

Instant access to a usable SIM card for Japan! Once you decide to visit, it’s essential to prepare. But have you ever thought about simplifying this process? With eSIM, after purchasing online, you’ll instantly receive a QR code for a SIM card usable in Japan. Done! You can even handle sudden business trips with ease! Reduce the risk of losing SIM cards! Some people buy a SIM card at the airport and swap it with their usual one. But after the switch, they lose the SIM card and have to go to the telecom company for a replacement upon returning home. This happens frequently. eSIM only requires a SIM card swap in the settings, eliminating this risk.

Dual SIM capability for handling two numbers while abroad for travel or business, sometimes you need to use your usual number for emergency calls or texts. With eSIM, you can set up two SIM cards on one device, enabling you to have two numbers simultaneously. It’s convenient for business trips. When traveling to Japan, you can purchase an eSIM from online Japanese stores. Since most of them are domestic companies, it’s more convenient and faster to seek help when encountering setup or usage difficulties. For example, CDJapan Rental is one of them, offering eSIM with larger data allowances (such as 30GB and 50GB), all utilizing Japan’s oldest and best-covered Docomo network, and at more favorable prices.

How to Check if Your Phone Supports eSIM

Checking if your phone supports eSIM is straightforward. Just confirm if it has an EID. Having an EID means your phone supports eSIM, while the absence of one indicates otherwise.

For iOS devices, you can simply dial a number to confirm.

Open your phone’s dialer interface. Dial *#06#. When entering the final #, some messages will appear on the screen, showing “EID barcode (or text)” if your phone supports eSIM.

Alternatively, you can check the EID code from “Settings” > “General” > “About.” For Android devices, navigate to “Settings” > “About phone” (the text may vary), where you can see the 32-digit EID code.
