Why Jet eSIM Is the Best Japan eSIM
An eSIM for Japan means no SIM swap at the airport, no roaming bill shock, and no hunting for Wi-Fi between Shibuya and Kyoto. Build your plan above, pay once, and your activation code arrives by email — scan the QR code and you're online before you leave home.
Every Jet eSIM Japan plan is data-only with hotspot sharing included, so you keep your phone number active for calls and texts while your maps, WhatsApp, translation apps, and train timetables run on fast local data.
Japan eSIM Unlimited Data Plans
Heavy user? Our Japan eSIM unlimited data plans give you a fresh allocation of high-speed data every single day of your trip — then data keeps flowing, unlimited, at 500Kbps on LTE, so you're never cut off. Upload every ramen photo, navigate every backstreet, and video call home without watching a data meter.
Pick the duration that matches your trip in the plan builder above — 5, 10, or 15 days.
Fixed Data Plans for Lighter Users & Longer Stays
Checking maps and messages more than streaming? Fixed data plans from 1GB to 20GB give you a full 30 days from activation — ideal for longer stays, working holidays, or travelers who mostly ride hotel Wi-Fi and just want reliable data on the move.
Bonus: 23 More Countries on Our Asia & Oceania Extended Network
Here's what makes Jet eSIM different from a Japan-only SIM: your plan works across 24 countries in Asia & Oceania. Adding a stopover in Seoul, island-hopping in Thailand, or flying on to Sydney? One eSIM covers your whole adventure — no extra plans, no extra cost, no swapping anything.
