KDDI (au) Japan eSIM | Unlimited 5G High-Speed ​​Internet | The World's Best Internet Experience

Speed is good, just maybe installation time a bit problem to me, saying activation fail but when reached japan no problem, so better check availability and make sure got data orwifi at your own country to finish install first

Can’t believe I got this for free as a gift from KKday. I purchased a day tour to Shirakawa-go and was gifted with a mysterious gift, which turned out to be a 7-day eSIM that offers 21GB of data in total. Since the purchase was last minute, luckily I got to use it before it expires (they only allow usage within 10 days I think). The signal is constantly strong and since its network is a Japanese one, there’s no problem such as blocked access to certain apps. If your tour isn’t sold out too fast, just purchase it at the last minute like I did and you might have the chance to make full use of this eSIM!

5G connectivity was flawless throughout Nagoya city, and even in Takayama and Shin-Hotaka districts, the signal remained stable, providing a truly excellent experience.

It truly deserves its reputation as the best network; it's incredibly stable, has excellent signal strength, and fast speeds!

I was originally using another company's eSIM, but it seemed like there was no signal when there were many people around. Sending messages and photos was slower than on a plane. I couldn't stand it anymore and switched to KKDay. It works smoothly in Tokyo. It gets slightly slower during sports games or events when there are many people, but otherwise it's very smooth. It's great, and the native card is the best! ✨

The signal is generally good in most areas where it should be, except for some areas where the signal is inherently weak.

Thank you so much for getting this esim trial! It's really great to use!

Four days of wireless internet access and 5G usage yielded mostly positive reception issues. I would definitely repurchase. The initial connection method using QR code scanning was also very convenient.

This is a great, fast internet card; I highly recommend it to everyone.

I set it up in Taiwan first, and then activated it directly in Japan with no network lag. It's fantastic!
