I recently started using eSIM, and it's so convenient! There's no need to swap SIM cards while traveling; I was able to activate it in just a few minutes using the app. In London, in particular, I was able to use the internet as soon as I arrived at the airport, so map and transportation apps worked immediately, which was reassuring. The connection speed is stable, and there are no problems with video or social media. There's no need to worry about losing it like with a physical SIM, and changing plans is easy, so it's convenient. The initial setup was a little confusing, but once you follow the steps, it's easy. I highly recommend it for international travel or short stays.

Coming to Japan alone is comfortable. No need to worry about communication. The signal is good, no cuts. Plus, you can watch many series. Calling the hotel, the signal is good. It's very good. Normally, I use roaming, so the internet runs out very quickly.

The connection speed is fast, no need to take out the card, just scan the QR code, it is very easy to operate, and the price is very cheap! I will definitely buy it again next time and will recommend it to my friends!

As advertised, easy set up, auto switching between providers. Good signal most of the time. Did not need to use Customer support. Will use again.

I used it on a trip to Spain, Italy (Vatican City), and France. It occasionally dropped to LTE, but the signal quality was generally good. It was very convenient.
