Doesn't work! Waste of money! I was only able to see if it works after arriving in Japan in March '25, but I never got connected when automatic carrier selection is on. I chatted with the BNESIM support and was told to select KDDI manually. After that I was able to get connected, for no more than 2 mins each time in a series of unsuccessful attempts. I then chatted with the support again. This time they said this case will be escalated to the advanced team and I'd be hearing from them within 24 hrs. Yes, you're right! The never responded to me afterwards! Sadly speaking, this is the second time I run into the same situation with them. I bought another esim in 10 mins from EIOTCLUB and I got continuous, stable connection ever since. So which one is the scam?

Driffle eSIM

broused in Japan

Installation was easy, price was okay. Coverage and speed were good.

However, the website said it would connect to all networks (docomo, KDDI, SoftBank, Rakuten) but only KDDI worked for me.

The usage display only updated every 5 days (not ideal). Top-up was not possible.

Overall an okay experience.

Nesa

Bokuused in Japan

As a proper Naija person wey no like wahala, I carry Nesa Mobile enter Japan and I must say e work like magic! From Tokyo to Osaka, network dey steady. No need to dey look for WiFi or disturb anybody for hotspot.

Activation na breeze I just scan small QR code, and boom, my phone don dey browse like say I never comot Naija.

Sometimes the speed go slow small, especially for some areas or inside train, but other times e dey fast well enough to browse, chat, even use map when I waka lost (no shame, e happen).

One thing I gatz salute dem for na customer support. When I get small issue, I message them and dem respond quick quick. No long story. Thanks Omar!

Infuriatingly slow even though eSIMDB customer service said low latency would feel snappier than 5G options. Couldn’t even use Google Translate image translation, and Google Maps takes significantly longer to load any given place’s details. Wouldn’t recommend or use again.

Break Out Point is Japan.
You will connect to IIJ (ISP)
You cannot use hotspot

I used their unlimited 3-day plan and could use more than 20GB of data, so it seems to be indeed unlimited. However, the speed was capped at 10 Mbps the whole time.
Traffic was routed through Hong Kong, so the latency was not great but not too bad.
The issue with a Hong Kong IP is that I couldn't access some services like ChatGPT.

WG JAPAN eSIM

Nicoused in Japan

Very good experience. I had a consistent connection during all my stay. The speed was good, and the latency was low thanks to the internet breakouts being in Japan.
The hotspot is working after setting up the APN as documented in their guide.
The price is pretty good given the good speed and low latency.

The price is a bit high but the network worked perfectly and the speeds were good. Also the app they have works very well.

The price is good and the speed is fine but in my case I suffered from several outages of even a few hours without service which can be a very negative factor.
