Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

Effortless to setup, was purchased later as the work phone needed active Internet later during our trip in Japan.Covered our locations of Tokyo, Yokohama, Saitama well and worked across these towns in Japan seamlessly. We had an alternate 4G docomo eSim in another phone but we didnt feel like any phone an issue.Very happy with the eSIM and would recommend it.

It works perfectly. If your phone supports eSIM, it's the easiest and cheapest way. Highly recommended.

I had no problems using this eSim in Nagoya, Okazaki and Matsumoto. It was a breeze, and I never lost access to the internet, which was super important as we were navigating the roads while driving, and really depended on Google Maps to get to all our destinations through the rural areas as well.

Great! Both the price and the data allowance are good. You can use the internet for extended periods without having to turn it off or worry about running out of data. The overall signal is good, except for some areas with poor reception. The internet speed is average, neither super slow nor super fast, but it works well without any lag. All apps open smoothly. This might be because the local internet signal isn't supposed to be super strong as it would interfere with the overall network, so it prioritizes consistent usability over high speeds. Overall, it's good.
