Japan Prepaid Travel eSIM

Our eSIMs are data-only and do not include a phone number. For calls and texts, we recommend using VoIP apps like WhatsApp, Facebook Messenger, Skype, or Google Voice.

Japan only. Coverage is nationwide on the SoftBank network, including Tokyo, Osaka, Kyoto, Hokkaido and Okinawa.

Your eSIM connects to the SoftBank mobile network in Japan. It supports 5G where available and 4G LTE everywhere else.

Each plan has a set number of days, listed on the product page. eSIMs can't be extended or topped up, but you can buy a new plan anytime.

Not on this eSIM. Each plan has a fixed data allowance from 5GB to 50GB. When the allowance is used up, data stops for the rest of the plan, so choose a size with some headroom or buy a second plan.

Dial *#06#. If you see a 32-digit EID number, your device supports eSIM.
(Note: MEID is not the same as EID.)

At sea, signals are usually only available via satellite networks, which our eSIMs do not support. Near ports, your eSIM will reconnect to local networks.

This eSIM is designed primarily for smartphones. While some tablets support eSIM, we cannot guarantee compatibility on all non-phone devices.

Our support team is available daily via live chat and email at hello@globalstarlink.com.au. We're happy to assist you with any questions.

After purchase, you'll receive a QR code via email. Scan it in your phone's mobile settings to download and install the eSIM.

Yes – you can install it before you travel. However, if you enter any country listed in the plan's roaming coverage before your intended destination, the eSIM will automatically activate. We recommend installing shortly before departure if you're transiting through other covered countries.

This eSIM will activate automatically when you arrive at your destination. Just make sure mobile data is enabled and data roaming is turned on in your phone's settings.

Yes. Once active, your eSIM will connect to a supported local network included in your plan.
Make sure your phone's Mobile Data is set to the eSIM and Data Roaming is enabled.

If manual activation is required, step-by-step instructions will be included in your QR code email.

You can monitor your data usage in your phone settings:

iOS: Settings > Mobile > Current Period (or Current Period Roaming)
Android: Settings > Network & Internet > Data Usage

You can also check your remaining data and plan status through our Customer Portal.

No, our plans are prepaid and cannot be extended. Simply purchase another eSIM plan if you need more data.

Yes, hotspot and tethering are supported and will use your data allowance.

First, check your data usage to make sure you haven't run out, and confirm that you're in a country included in your eSIM plan. If everything looks fine, try toggling Airplane Mode on and off, restarting your device, or manually selecting a network in your phone's settings.

For step-by-step instructions, refer to our eSIM Troubleshooting Guide. If you're still having issues, reach out to our support team and we'll be happy to help.

These eSIMs are data-only, which means they don't support traditional phone calls or SMS. However, you can still stay connected by using apps like WhatsApp, FaceTime, Facebook Messenger, or Google Voice to make calls and send messages over data.

Yes – you can keep your own number while using this SIM Card. If your phone supports dual SIM, leave your home SIM in the device, but make sure Data Roaming is turned off for it. Then, set your travel eSIM as the primary for Mobile Data. This way, you can still receive calls and texts to your own number over Wi-Fi or regular mobile signal (depending on your provider) without incurring roaming charges.

Absolutely! You can use internet-based calling and messaging apps like WhatsApp, FaceTime, Facebook Messenger, or Google Voice. These apps work well over data and are a great alternative to traditional calling while travelling.

It depends on your trip. A travel eSIM is set up before you leave, so you land already connected — no queuing at an airport kiosk, no local ID or passport registration where that is required, and no risk of losing your home SIM while you swap cards. A local prepaid SIM can still work out cheaper on a long stay, and it gives you a local phone number.

This plan starts at $7.90 AUD and covers Japan.

Buy before you travel. Your QR code is emailed to you right after purchase, so you can install the eSIM while you are still on home Wi-Fi and have it ready to connect the moment you land. Installing after you arrive needs an internet connection you may not have yet — which is the situation the eSIM is meant to solve.

Installing early does not start your plan: the validity period begins when the eSIM first connects to a network at your destination.

For data, usually. Roaming with an Australian carrier is normally charged as a fee for every day you are away, so the cost grows with the length of your trip. This plan is a single upfront cost from $8.90 AUD that covers the whole plan period in Japan.
