I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.

This was my first time using an eSIM to access the internet while overseas. Previously, I found purchasing and replacing physical SIM cards a hassle, but eSIMs eliminate that hassle entirely, making them incredibly convenient. 🍋 The entire process, from application to setup, was completed online, and I was able to start using it simply by scanning a QR code. The instructions were easy to understand, and even though it was my first time using an eSIM, I was able to set it up without any trouble. 📣 The data speed was very stable in urban areas, and I was able to use social media, map apps, and watch videos without any issues. Although there were some slight drops in speed in some locations, I felt it was sufficient for everyday use. 🪾 The fee was also relatively reasonable, significantly lower than international roaming. For this price and data quality, I think it's great value for money. 🍓 The fact that no physical SIM is required and that it can be set up before departure was particularly appealing. However, I was a little concerned about the limited compatible models and weak signal in some areas. 😔 Overall, I was very satisfied with the service. This eSIM is highly recommended for those who want to easily use the internet while traveling or staying abroad for a short period of time.

I had problems with my auto roaming when I was travelling in China. Contacted my service provider multiple times and couldn't resolve my issues. In the end, my cousin recommended me to use this and the experience was great. I will be recommending this to my friends too!

It can be used without any problems. It's convenient because once you complete the setup once, it switches automatically for both transit in Shanghai and Thailand. The activation process is a little long, so you might feel anxious until it's finished, but it's easy; all you have to do is scan the QR code and proceed. Once you change the settings, you can also use TikTok and other apps!
