[eSIM] Japan eSIM 30 Days Data Only SIM | 50GB High-Speed 4G LTE + Unlimited Data at Reduced Speed | No Roaming Needed for Faster, Safer Access | Hotspot tethering Supported | Docomo | Made in Japan

It works really well for $20, and 10 GB is super generous; that should last all month for Google Maps, email/texts/Snapchat and any menus or destinations you need to research on the go.It is decently fast most of the time, and you'll have coverage in most tourist areas. I even used it in Hokkaido and on the lower parts of Mt. Fuji!The only downside is I occasionally had periods of "No Service" in areas of coverage that would resolve after restarting the phone or cycling on/off airplane mode.All the people who say it did not work likely had the following issues that can be avoided by reading about your phone and this plan:1) Your phone is not unlocked2) Your phone does not support the 4G LTE bands that are listed in the specifications on this Amazon listing3) You did not correctly enter the access point name (APN settings) that are included on the install paper with the SIMAn alternative if you can't/don't want to read any tech specs is to just shop around for an eSim, again, IF your phone supports eSim!

We spent hours trying to follow their sketchy instructions, got one or two minutes of weak connectivity only. Android phone.

I really recommend this if your phone needs a SIM card to use in Japan. Easy to install. “DOCOMO”, the provider for this SIM card is one of the best providers you can trust in Japan. I used it for 17days in Osaka,Tokyo,and Hokkaido and never had problems.I’ll definitely buy it again whenever I go to Japan!

As soon as i landed, the sim connected to M-AIR Tokyo data service. But my iPhone showed no cellular connection the whole time. Disappointing. I had printed out directions to my Airbnb in Tokyo, if I hadn’t done that I’d have been in trouble.Then I realized that I had to set the new data service as the primary cellular data source. Once I did that I was all set.

I traveled to Japan recently for two weeks and 10 gb was enough for me. The connection was perfectly fine. Of course, whenever I had a chance to connect to free Wi-Fi, I did just to save my data. when I left Japan, I still had 3gb left. Highly recommend to whom has problem connecting to the E sim.

Ordered this for my 2 week trip to Japan in June 2024. I visited Osaka, Kobe, Kyoto Odawara, Tokyo and it worked in all cities and even on the Shinkansen bullet between when the internet was slow on the train. I used an older unlocked android phone and it was plug and play (only works when in Japan but no activation needed). Only 4g but rate must be good since it was way better than the free 256kps at 5G I was getting from my own TMobile plan. Good enough for my 5yo to watch YouTube kids on and definitely good enough for Google translate camera (essential). I only used 5gb over 2 weeks but I made sure not to waste gb when in the hotels. Free wifi is available at several places but often requires registration. Also price beat wife's $12/day international plan on att. Worked a charm!

I bought this for my three week stay in japan this past may and it ended up not working with my phone. I had an iphone 13 btw. i’m not sure if i did something wrong but it didn’t work and i never was able to use it.

I have used it with an iPhone 12 while traveling in major cities in Japan. Only during first arrival at the airport the connection was slow, presumably because everyone was busy using their phone. Other than that the signal strength was generally strong and the speed decent for web surfing, navigation, etc. The reason I gave it only a 2-star rating is because the personal hot spot did not work. In the Amazon description it says the card will support “tethering” to other devices. This sounds like false advertising to me thus the low rating. Fortunately we also have a pocket WiFi; otherwise, our access to WiFi would have been severely restricted for a family of four.

Worked well overall in big cities in Honshu and Hokkaido. Not the fastest at times but suitable for travel usage. In between cities on shinkansen, or in rural areas, it may lose registration with the network even though it showed up on the list, possibly due to my phone didn't support the frequencies in those areas. Once getting in town, usually I could manually or automatically re-register with the "M-Air" network. Sometimes it required setting the phone to flight mode and back, and it'll register. Overall happy with this SIM.

Estupendo producto, muy valioso para los viajeros a Japón

Didn't work first time for iPhone, but swapped to my old Android phone and use its via personal hot spot. No issues whatsoever.My companion had no issue getting it to work with iPhone, it was my fault, i need to read the instruction.Anyway, no issue with it whatsoever in my recent trip to Tokyo and Osaka.

日本に一時帰国した際に利用しました。 帰国前に実家に届くようにし、 帰国後すぐ使いました。セットの仕方も簡単で、 何も問題なく使えました。SIMカードを入れる部分を開けるための金具も一緒に入っていたので助かりました。

For google maps, tiktok, insta ect it worked fine. It wasn’t the fastest speeds on earth but for what you pay and what you gets it’s great a lot cheaper than what I say in Japan ! It did display no bars on my phone tho but it still worked so I ain’t complaining. Heads up it’s LTE no 4g hence why it’s a little slower
