Make your data work for your trip
Daily GB · Data per day
Illustrative example
Example: Daily 1GB for 5 days gives you 1GB of high-speed data each day. Tomorrow brings a new 1GB allowance. You cannot use all 5GB on day one. Reset time and speed after the daily allowance depend on your plan.
Total GB · Data for the whole trip
Illustrative example
Example: Total 5GB for 5 days gives you 5GB for all 5 days combined, not 5GB each day. Use 2GB today and 3GB remains for the rest of the plan. It does not reset tomorrow. Treat the plan as offline once the high-speed data is used.
Unlimited does not mean unlimited full speed. Check the speed cap and hotspot conditions for the selected plan.
Delivery & setup
Your eSIM QR code is sent to the email entered at checkout. Check device compatibility before ordering; install with a stable internet connection and do not delete it when troubleshooting.
Please activate & use within 90 days of purchase (eSIM). Once activated, the plan lasts for the number of days you selected.
Follow the selected plan's setup instructions above. Roaming services require Data Roaming ON; local-plan exceptions are shown with your selection.
Actual signal and speed vary by location, device and network conditions.
Full product specifications
🌐 Japan Travel eSIM
Reliable high-speed data across Japan, auto-connecting to the country's top networks.
🌐 Connects to Japan's top local networks — Docomo, Rakuten Mobile, KDDI — auto-selecting the strongest signal wherever you are.
📊 Plan Types
🚀 Daily — a fresh batch of high-speed data every day. It renews daily whether or not you used up the previous day's data, so you're never left without data mid-trip. (Exact renewal time varies by plan.)
📦 Total GB — one fixed data pool you can use anytime, no daily limit. Once it runs out the connection stops until you top up, so choose the size that fits your needs.
♾️ Unlimited — never run out; speed managed under fair use. For heavy users & long stays.
💡 How much data? 1GB/day = maps, chat, social, email (light). 2–3GB/day = video calls, photos, some streaming (medium). 5GB/day or Unlimited = heavy streaming, video, work.
🔋 Check your remaining data anytime at the Happy Travel SIM website — Total GB plans can be topped up there too.
📩 How to get it: leave your email in “Message to Seller” at checkout — your eSIM QR is sent instantly. Scan & go.
⚠️ Please note
• Unlimited plans do NOT support hotspot / tethering (fair-use policy).
• Please activate & use within 90 days of purchase (eSIM).
• eSIM: installs on ONE device, ONE time; the QR can't be reused once installed or deleted.
• Not sure your phone supports eSIM? Dial *#06# — if an EID number appears (not the IMEI), your phone supports eSIM.
