General questions about eSIMs

・What is an eSIM?

An eSIM is an industry standard digital SIM. By using an eSIM, users can access Japan’s mobile network without a physical SIM card.
The main difference from physical SIM cards is that users can complete the transaction entirely online, as opposed to needing to purchase & receive physical cards.
At RakuRaku JAPAN eSIM, there are a wide array of purchasing options with great deals, so don’t miss out.

Please note that the RakuRaku JAPAN eSIM plan is network-only and no call services are available.

After purchasing an eSIM, you can activate it by using the passcode sent to your email address.

Have the best time in Japan by using our eSIM data services!



・Can I use both a physical SIM card and an eSIM at the same time?

This depends on the device you use. If your device supports dual SIMs, then yes, you can use both at the same time. If your device does not support dual SIMs, then you can only use one SIM card at a time.



・What kind of device supports eSIMs?

All SIM-free devices that support eSIMs.

※If your device is not SIM-free, you cannot use an eSIM.

For unlocking your device’s SIM, you will have to contact your device’s provider or manufacturer. RakuRaku eSIM JAPAN will not be able to support inquiries about SIM locking, so be sure to note this before making a purchase.



・What is a SIM-free device?

A SIM-free device is a device that has no restrictions for SIMs.

Your device’s SIM may be locked or restricted, depending on the country of purchase, network operator, or store of purchase. Please check if your device is SIM-free before purchasing an eSIM.



・How can I check if my device is SIM-free or not?

Low-volume eSIMs are also available for connection testing. If you are not sure whether your device is compatible with eSIM, please consider using the trial plan (500MB/2 days).


For iPhone users:

Go to Settings > General > About > Carrier Lock

If it says “No SIM restrictions”, then your device is SIM-free.

If it says “SIM locked”, then your device is SIM locked, and you will have to unlock this prior to using an eSIM.


For Android users:

(Procedures may vary depending on the maker of your phone)

Go to Settings > Device Information > SIM Card Status > SIM Lock

If it says “No SIM restrictions” or “SIM allowed”, then your device is SIM-free.


If you need further assistance, please contact your place of purchase or the maker of your device.



・Can I call somebody, or send SMSs?

・Can I make calls or send SMS with eSIM?

No, our plans are network-only, therefore you cannot call or send SMSs.

You can, however, call somebody through network applications like Facetime.



・Is tethering possible?

RakuRaku JAPAN eSIM basically supports tethering, but some smartphone models may not support it.



・When does my data plan start?

・Will we receive an eSIM package?

An eSIM is a digital SIM card, so it does not include any physical packaging. Once you place your order, you will receive an email with a serial code for eSIM activation.



・When should I place my order?

You can place an order for an eSIM anytime, but we suggest purchasing before arriving in Japan. When you finish your purchase, you will soon receive an email including the activation code.

You can use this code to install your eSIM as soon as you arrive in Japan. However, note that the installation date will become the starting date of your data plan, so make sure you don’t install the eSIM before coming to Japan.



・Can I data charge my eSIM? / Can I purchase additional data packages?

You cannot data charge the eSIM, however, if you used up your data, you can purchase another eSIM from RakuRaku JAPAN eSIM to access the internet again.



・Can I repurchase an eSIM?

Yes, there are no limits to repurchasing.


・Can I cancel my order?

Unfortunately, cancellations or returns are not possible after purchase, due to the nature of the product.


・If I bought the eSIM beforehand, will it activate later automatically?

No, the eSIM will not activate automatically. Customers have to activate their eSIMs by using the activation code sent via email.



・My device does not support eSIMs. Can I get a refund?

Unfortunately, we cannot accept refunds since retrieving or reselling eSIMs are impossible once installed.

Low-volume eSIMs are also available for connection testing. If you are not sure whether your device is compatible with eSIM, please consider using the trial plan (500MB/2 days).
