About Jet eSIM
Jet eSIM exists to solve one problem: staying connected in Japan without airport SIM queues, pocket WiFi rentals, or roaming bill shock. We sell travel eSIMs built around Japan — with bonus coverage across 23 more countries in Asia & Oceania included in every plan, at no extra cost.
What we do
Every Jet eSIM plan is data-only with hotspot sharing included, so your phone number stays active for calls and texts while your maps, messaging apps, and train timetables run on fast local data. Choose the plan that fits how you travel:
- Unlimited data plans — a fresh allocation of high-speed data every day of your trip, for 5, 10, or 15 days. And you’re never cut off: after your daily high-speed allowance, data keeps flowing unlimited at 500Kbps.
- Fixed data plans — from 1GB to 20GB, all with a full 30 days of validity from activation. Ideal for longer stays, working holidays, or lighter users who mostly ride hotel Wi-Fi.
One eSIM covers your whole adventure. Adding a stopover in Seoul, island-hopping in Thailand, or flying on to Sydney? Your Jet eSIM works in 24 countries across Asia & Oceania — no extra plans, no swapping anything.
An official Maya partner
We’re an official partner of Maya, so every eSIM we sell runs on established local carrier networks. That means real 4G/5G speeds in Japan and reliable coverage across our extended Asia & Oceania network — not a reseller mystery box.
How it works
Buy your plan, and your activation QR code arrives by email within minutes. Scan it before you fly, and data switches on automatically when you land in Japan. No physical SIM, no airport kiosk, no paperwork. Jet eSIM works on all recent eSIM-compatible iPhone, Samsung Galaxy, and Google Pixel devices — check our how it works guide for the full walkthrough.
