“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. ”
“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.”
“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.”
“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”
“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!”
“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.”
“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 plan for Japan. The available options are fixed‑data plans, for example a 200GB plan for 360 days priced at $290 and another 200GB plan for 360 days at $390, as well as a 100GB plan for 360 days priced at $190 and $290. There is also a 60GB monthly plan for 30 days costing $45, which includes a reduced speed of 2000 kbps. Fixed data plans may be more cost‑effective for most travelers unless the user requires very high data consumption.
Does Ubigi offer Japan eSIM with phone number and SMS?
Ubigi does not provide any eSIM plans for Japan that include a phone number or SMS capability. All of Ubigi’s offerings for Japan are data‑only plans, so travelers will not receive an incoming or outgoing voice or text feature.
Because of this, users must rely on internet‑based applications such as WhatsApp, Telegram, or iMessage for calls and messaging. These VoIP services work over the data connection that the Ubigi eSIM provides, allowing communication without a traditional phone number.
How many data plans does Ubigi offer for Japan?
Ubigi offers a total of 15 single‑country plans and 44 multi‑country plans for Japan. The available plans span data caps from 500 MB up to 200 GB, with prices ranging roughly from $2 to $390, providing a wide range of options for travelers depending on their data needs.
