Frequently asked questions

How do I know if my phone works with a Japan eSIM?

Your phone must be carrier-unlocked and natively support eSIM technology. Most modern smartphones, such as iPhone XS or newer and recent Samsung Galaxy devices, are fully compatible. You can check your device settings or dial *#06# to verify if an EID number is displayed.

How much data do I need for a trip to Japan?

For daily navigation via Google Maps, translation tools, and light social media use, 1 GB to 2 GB per day is usually sufficient. If you plan to stream video or upload extensive travel content, consider an unlimited or higher-tier plan. Most travelers find a total of 10 GB to 20 GB ideal for a typical 10-to-14-day Japan itinerary.

When should I install and activate my Japan eSIM?

You should install the eSIM profile prior to departure using a stable Wi-Fi connection. Keep the eSIM line turned off until you land in Japan, then turn it on and enable Data Roaming to connect to local networks like NTT Docomo or SoftBank. The validity period generally begins only when the eSIM connects to a supported Japanese network.

Will WhatsApp, Instagram, and iMessage still work in Japan?
Yes

all your messaging and social media apps will continue to function normally without any re-configuration. WhatsApp and iMessage remain linked to your original phone number, allowing your contacts to reach you seamlessly. The eSIM simply provides the mobile data required to keep these applications connected.

Does the Japan eSIM come with a local phone number?

Most travel eSIMs for Japan are data-only plans and do not include a local (+81) phone number for standard voice calls or SMS. You can easily make voice or video calls using internet-based apps like WhatsApp, LINE, FaceTime, or Skype. Note that LINE is the most widely used messaging app for local services and businesses in Japan.

What should I do if my eSIM does not connect upon arrival in Japan?

First, verify that your eSIM line is toggled on and that Data Roaming is enabled in your cellular settings. If you still have no connection, restart your phone or toggle Airplane Mode on and off to force a network search. You can also connect to free Wi-Fi at major airports like Narita or Haneda to access customer support if needed.

How does an eSIM compare in price to standard international roaming?

A local travel eSIM is substantially cheaper than home carrier roaming, which often charges $10 to $15 per day for limited data. eSIM plans offer direct access to local Japanese network rates without hidden daily fees or unexpected overage charges. Buying an eSIM ahead of time allows you to lock in a fixed price for your entire trip.
