Have you ever purchased a SIM when you travel abroad?

When traveling abroad, many people opt to either buy a SIM card or rent a portable Wi-Fi device. However, using a SIM card can be a hassle. It involves the time-consuming task of inserting and setting up the SIM card in your smartphone, and there's always the risk of losing or damaging it.

To avoid these inconveniences, we recommend using an eSIM.

1. What is an eSIM?

eSIM stands for embedded SIM. It allows you to simply rewrite the information on the SIM card that's already installed in your device, eliminating the need to remove or insert any physical SIM cards.

You can activate it easily by scanning the SIM information from a QR code provided to you or manually entering the information into your phone. The eSIM is incredibly convenient because the time from application to activation is short. Plus, you can use two different lines on a single phone without having to remove your existing SIM card, offering a convenient and stress-free option for travelers.

2. Three Key Benefits

Below are three recommended points to consider when purchasing a GTN eSIM.

Point 1) Easy Online Application!

Once you order an eSIM, you'll receive all the necessary details in your registered email. After your order, setting up the eSIM is as simple as configuring a few settings on your smartphone, and it's ready to use. Unlike physical SIM cards, there's no need to wait for delivery or visit a store for purchase; everything from ordering to activation is completed online. This process significantly reduces the time and effort required to start using the service.

Point 2) Convenient Prepaid eSIM Without the Need for Replacement!

With no need to swap your physical SIM card, there's no risk of damage or loss. Plus, as a prepaid eSIM, it comes with no minimum contract period and no cancellation fees.

Point 3) Data Top-Up Available!

Should you use up all your data, topping up is easy. Simply contact us by phone or email within your usage period.
*Top-Up Fees (tax included): (1) 500MB for 550 yen (2) 1GB for 1,100 yen
