How long does it take to receive the Japan eSIM?

Your Commbitz Japan eSIM QR code is delivered by email within seconds after purchase.

Which network does the Japan eSIM use?

Daily plans run on Softbank; multi-operator Bundle plans roam across DoCoMo, KDDI, and Softbank; Unlimited plans use KDDI. Coverage spans Tokyo, Kyoto, Osaka, Mt. Fuji, Hokkaido, and most popular destinations.

Is the Unlimited Japan eSIM really unlimited?

Yes — the KDDI Unlimited plans have no hard data cap. Speeds may be moderated only if your usage is well outside fair-use limits.

Can I keep my Indian SIM active?

Yes. Your Indian SIM can stay active for calls and SMS while the eSIM handles Japan mobile data.

When does the plan validity start?

Your validity starts when you install and activate the eSIM on your handset, not when you buy it.

Connected the moment we cleared Haneda immigration

Scanned the QR on the flight and Softbank was already showing four bars when we deplaned. Booked the Keikyu Line tickets from the platform — zero airport SIM-counter queue.

10 days across Tokyo, Kyoto, Osaka on the Unlimited plan

Took the 10-day Unlimited (KDDI) — no quota anxiety on a 4-city Shinkansen tour. Google Translate camera mode, Maps, video calls back home, nightly streaming. Worth every rupee at this price point.

Mt. Fuji and Hakone day trip stayed online

Worried about signal in the Five Lakes area but the multi-operator Bundle held up beautifully — DoCoMo picked up where Softbank didn't. Tea ceremony bookings, Hakone ropeway timings, all on tap.

Kyoto temple-hopping with translate on tap

Fushimi Inari, Kinkaku-ji, Arashiyama bamboo grove — Maps + Translate kept us moving through the day. Even in narrow Gion alleyways Softbank stayed at 4G. Setup on iPhone 15 took 90 seconds.

Osaka Dotonbori nights, Hokkaido snow trip both covered

Did Osaka first then flew to New Chitose for Niseko. The eSIM stayed connected through Sapporo, Otaru, and even up in the ski lifts. Indian Airtel kept ringing for OTPs throughout — perfect dual-SIM setup.
