4 out of 5 stars
Japan

“I tested Ubigi (5G) and TravelKon (Docomo IIJ) (LTE only).
Both have Japan IP address.
But TravelKon is faster ping (45ms) instead of Ubigi (120ms) even on 5G.
TravelKon (Docomo IIJ) is recommended. ”

Milk

5 out of 5 stars
Japan

“Was very happy with service. 5G phone connected at 5G. One of the few options in Japan that will do that. Most roaming services won't and a lot of other prepaid providers won't.”

cavok

5 out of 5 stars
Japan

“Service was 4G rather than 5G but speeds were perfectly fine, even for real-time navigation. The few low numbers recorded in speed tests were almost all at Narita Airport.

10 GB each turned out to be plenty for 9 days in Tokyo. We did connect our phones to the hotel's WiFi but probably didn't need to.”

AC

5 out of 5 stars
Japan

“Works great! Good coverage (docomo network it seems), Japanese IP, and good ping times to Europe. Used with an iPhone XS on LTE. Attached Speedtest is from a train”

Tommy

5 out of 5 stars
France

“It was great value for money for my trip to Japan. Very simple app.
I only regret one thing: not having known about it sooner!”

Milie

1 out of 5 stars
Japan

“Very poor experience. My data would be spotty at best, even with full bars. Certain websites would not load, sometimes Facebook and Instagram would not load. My email would only sometimes work. WhatsApp would seldomly send.

Not recommended.”

Traveler

“Good & solid experience! Balance, refill & plans via the website! Good 4G data speeds in japan (15-20mbps)!”

Ubigi for Japan FAQ

Does Ubigi offer unlimited data eSIM for Japan?

Ubigi does not provide an unlimited data eSIM for Japan. Their current Japan offerings are fixed‑data bundles, the largest of which is 200 GB for 360 days, delivered on a 5G network.

The other available options include a 100 GB bundle for 360 days and a 60 GB per‑month plan with a 30‑day validity that reduces speed after the free data amount is reached. While a fixed data plan guarantees a set amount of data, it may be more cost‑effective for most travelers unless they require very high usage levels.

Does Ubigi offer Japan eSIM with phone number and SMS?

Ubigi does not provide a Japan eSIM plan that includes a phone number or SMS functionality. Only data‑only eSIMs are sold for Japan, so travelers cannot receive inbound or outbound voice calls or text messages directly from the network. If calls or messaging are needed, users can rely on internet‑based VoIP applications such as WhatsApp, Telegram or iMessage over the data connection; however, availability of these services can be limited in some areas, so travelers should verify that the apps they intend to use are accessible in Japan before purchasing.

How many data plans does Ubigi offer for Japan?

Ubigi offers 14 single‑country data plans and 44 multi‑country plans that include Japan. The plans range in price from about $2.00 to $360.00 and provide data caps between 500 MB and 200 GB, with validity periods from 1 to 365 days. Most of the plans are fixed‑data‑cap options, while a single daily‑data‑cap plan is also available.
