Japan 5 GB / 30 days eSIM

Buy a data-only Japan eSIM from SecretESIM. 5G, hotspot, and a visible fair-use policy on unlimited plans. Every paid plan includes Emergency 500 MB on the same eSIM so you never get stranded without internet.

SecretESIM is your secret to staying connected in Japan — data-only eSIM, no phone number, SMS, or voice. You keep your home SIM for calls and use the travel line for internet. 2 live plans are published for this destination right now, starting from €8.99. 5G is available on listed plans. Hotspot / tethering is allowed where the card says HOTSPOT.

Validity starts on first use in Japan unless the card says it starts at install. That matters if you install on Wi-Fi at home a week before the flight: fixed-GB plans typically do not burn days until you land. Unlimited day-pass style plans are the exception — we print that on the card.

There is no unlimited SKU on this destination in the live catalog today. Fixed GB plans show €/GB so you can compare.

Operators we currently list: NTT Docomo, SoftBank, KDDI. When two plans offer the same GB and days, the store highlights the better price and shows the other option as “same GB, +X”. Emergency 500 MB sits on the same eSIM if the main bucket hits zero — WhatsApp, maps, rides, and the SecretESIM app.

Buy before you fly, install on Wi-Fi, then enable data roaming on the SecretESIM line after landing. Guest checkout is email + pay — no account required. Invoice PDF is in My eSIMs. Refunds apply if the profile was never installed, within 14 days.

Top-up keeps the same ICCID when the provider allows it — no second QR. Trip planner compares N local packs vs one regional vs one global if Japan is one stop among several. Compatible phones: iPhone XS and newer, Pixel 3+, Galaxy S20+, and other eSIM handsets in our device list. Carrier-locked phones may refuse a travel eSIM.
