How does our Japan eSIM work?

An eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.

How much travel data do I need with my Japan eSIM?

When you’re in Japan, it’s handy to have reliable mobile data so you can always stay connected, without needing to worry about finding Wi-Fi. Prepaid eSIM data is perfect for maps, driving directions, and more.

Not sure how much data you’ll need? There’s no pressure! You can always start with a basic 1 GB data package and add more if it’s needed.

We also have a travel data calculator to help you estimate how much data you’ll need for your trip.

Will I pay roaming charges with a prepaid SIM card for Japan?

You won’t pay a penny in roaming charges!

Install your Japan eSIM while you have a strong internet connection (either at home, or while already travelling), and then activate your prepaid Japan data package when you’re ready to use it.

To avoid roaming charges on your primary SIM, please make sure you’ve turned off Data Roaming on your primary SIM to prevent your home carrier from adding roaming charges to your next bill.

FAQs about using a Japan eSIM

Check my device

Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM.

Free Wi-Fi is great when it’s available, safe, and working well, but some destinations make it just about impossible to get a good connection. That’s why it’s nice to have data as a backup to stay connected.

We’re proud to provide aloSIM customers with fast eSIM data connections that allow them to talk, text, surf, and stream comfortably. You’ll likely experience a 4G (sometimes 5G) or LTE equivalent network in most locations, depending on what’s available in the area.

Installation guides

We have detailed eSIM installation instructions for all compatible devices, so whether you’re looking to add eSIM data to an iPhone or iPad, Google Pixel, Samsung Galaxy, or something else, we’ll be able to walk you through the eSIM set-up process easily.

How to avoid roaming charges

It can be confusing to know the best roaming settings for your phone while you travel internationally, so we’ve created an easy walk-through guide to show you exactly how your phone’s roaming settings should look.
