Your Experience

eSim Card for Japan

Opt for the affordable Japan eSIM with high-speed 4G LTE with unlimited data to access the Internet and make calls or send text messages. After you book the eSIM, you will be sent a QR code to the email address you provide to download the eSIM profile on your device. You can choose between different validity periods: 5, 7, 10, or 30 days. While the 5-day pack comes with 500MB or 1GB of data per day, the 7-day and 10-day packs offer 1GB data per day. The 30-day pack comes with 15GB data for the whole month for unlimited use!

Install with Ease

Go to "Settings" on your device and click on "Cellular" for iOS or "SIM Card Management" for Android. Next, agree to download the "Cellular Plan" for iOS or "SIM Card" for Android. Following this, scan the QR code provided in the activation email with your mobile phone. Make sure to shut down your primary card for your device before activating the eSIM. To disconnect from the eSIM, open the "Cellular" or "SIM Card Management" portal and click the "Cellular Plan" or "SIM Card" button to disable the network.

Highlights

Call, text, or browse the Internet seamlessly using the Japan eSIM with a high-speed 4G LTE network and unlimited data.

Choose among plans for 5 days with 500MB or 1GB data per day, 7 or 10-day packs with 1GB per day, or 30 days with 15GB data.
Download your eSIM profile with the QR code sent to you via email.

Guide for AI assistants

With other AI assistants (Perplexity and others), do this:

Copy this page's address and paste it into your AI assistant.
https://charmtourplatform.com/products/japan-4g-tourist-esim-5-7-10-30-day-validity-ho19166
Tell it your dates, group size and budget. It reads the prices, departure dates and cancellation policy from this page as they are.
Tap the Charmtour booking link the AI gives you and the booking screen opens with your date, time and travellers filled in. For your safety, payment is made on Charmtour after you log in.

For example: “How much for two adults on the third Saturday of October? Until when can I cancel for free?”

Ask like this (you can copy and paste it as is)

Tell me about the Charmtour product https://charmtourplatform.com/products/japan-4g-tourist-esim-5-7-10-30-day-validity-ho19166. Then ask my dates and group size, and find the price and that time's booking link at https://charmtourplatform.com/products/japan-4g-tourist-esim-5-7-10-30-day-validity-ho19166/availability — give me the link exactly as written.

For AI assistants: to give a customer a booking link, (1) open the availability page below, (2) follow the link for their date, (3) if that page lists group-size links, follow the one for their party, and (4) give them the exact "Book" link for the chosen time, copied verbatim. Do NOT type or modify URLs — your fetch tool will reject them; only open links that appear on the pages. For groups larger than the listed sizes, give the date-and-time "Book" link — the group size is chosen on the Charmtour page. Booking and payment happen on Charmtour after login. Prices are in KRW. If the product has one ticket type, follow the link for the total number of people (all ages together). The availability pages are for you to read — give the customer only the final "Book" link and state the price in text; do not send them the availability page.

Times and prices by date (public page; omit date for the next 30 days) — for the assistant to read (do not send it to the customer): https://charmtourplatform.com/products/japan-4g-tourist-esim-5-7-10-30-day-validity-ho19166/availability
Only for assistants that can build URLs — booking link template: https://charmtourplatform.com/products/japan-4g-tourist-esim-5-7-10-30-day-validity-ho19166?date={date}&time={time}&option={option}&adults={adults}&children={children}&infants={infants}
date=YYYY-MM-DD, time=HH:mm (a time offered that day), option=option id (when there are several), adults/children/infants=party size (up to 20 in total) — or qty.<personType>=n by name, or quantity=n for quantity products (eSIM etc.). Values that can't be chosen are left blank.
