Have you ever purchased a SIM when you travel abroad?

If you are a frequent traveler, you have probably already bought one before so you wouldn't have to rent a pocket Wi-Fi and carry it around in your bag all the time.

But it's not always easy to use them, right?

You have to open the card insertion slot of your phone with an ejection pin, remove the existing SIM, insert the new one in the right direction, and then reinsert it.

You must also keep the removed SIM in a safe place so you won't lose it or damage it upon your return from your trip.

The “eSIM” saves you from all of these hassles.

eSIM stands for embedded SIM.

By simply rewriting the information on the SIM that is pre-embedded in your device, the SIM card does not need to be inserted or removed.

The SIM information can be added by scanning a QR code or manually inputting it into the phone.

This makes it quick and easy to sign up for an eSIM service, and allows you to use two lines on one device.

In this article, let's look at the four simple steps of using an eSIM.

(1) How to use an eSIM

(2) Devices compatible with eSIM

(3) What to keep in mind with eSIM

(4) Where to purchase eSIM

(3) What to keep in mind with eSIM

Make sure your phone is an eSIM compatible model.

Not many devices are compatible with eSIM, so make sure that your smartphone is an eSIM compatible model before applying.

You can only use the eSIM with the device that scanned the QR code.

Once the QR code is scanned, it can only be used with that device. If you wish to use your existing eSIM on a new device, you must complete a separate online procedure to do so. (A fee may be charged for reissuing a profile.)

Note that there may be an eSIM reissue fee when changing devices, so if you change devices frequently, pay attention to this fee.

Only a few carriers offer eSIM-enabled plans.

Not many carriers currently offer eSIM in Japan, so when buying an eSIM in Japan, check where it is available.
