eSIMzio’s Japan plans connect to SoftBank and KDDI with 5G where available — the app shows the real network you’re on.
Google Maps, Japan Transit, DeepL and Suica top-ups all need data. Budget more than you think — the 10 GB / 30 days plan is the sweet spot for a two-week trip.
Your eSIM arrives the second you pay. Add it at home over Wi-Fi and it activates only when it first connects in Japan.
One plan can hotspot a second phone or laptop — often cheaper than buying two small plans.
Pick a Japan plan and pay securely with Stripe — right here in your browser or in the app with Apple Pay / Google Pay. Your eSIM is delivered the instant payment succeeds.
One tap on most phones, or scan the QR. Do it at home — the plan only starts when it first connects abroad.
Switch the eSIM on for data when you arrive and watch your live usage in the app.
Japan data plans start at £1.50 for 500 MB / 7 days, up to 10 GB and unlimited options. The price you see in the app is exactly what you pay — no roaming charges on top.
eSIMzio’s Japan plans connect to SoftBank & KDDI with 5G where available. The app shows the real operator and coverage before you buy — we never invent coverage claims.

Yes, and we show it up front: unlimited Japan plans reduce to 1 Mbps after 3 GB of use per day, then restore at full speed the next day. You’ll see this on the plan card in the app before paying.
Yes. The travel eSIM runs alongside your usual SIM, which stays active for calls, texts and WhatsApp — only your data routes through the eSIM.
