Great eSIM for use in the US. Installation was quick and trouble-free, and the connection worked immediately upon arrival. The speed was good for navigation, social media, and daily use. Truly a top choice for this price!

Excellent and very convenient service! Everything works well, connection is easy, and it works flawlessly. It's much cheaper than buying a SIM card locally. I definitely recommend it!

After installation at the airport, it can be used upon arrival in the United States. Very convenient.

This was my first time using an eSIM, and it was surprisingly easy. I received a QR code via email immediately after purchase, and I was able to quickly set it up at home before departure. I was honestly impressed that I had 5G connectivity the moment I arrived at the airport. While the signal was weak in some parts of the New York subway, it worked almost flawlessly above ground. The day pass system was also helpful, allowing me to save money by only activating it on days when I wanted to focus on sightseeing. I also stopped in Vancouver, Canada for a few days, and the fact that I didn't need to switch SIMs and could continue using it was a major advantage.

I used this eSIM in the U.S. for over 10 days with absolutely no issues. It was definitely worth it — the internet speed was very fast almost everywhere, except when I was underground, like in the subway.

Works well except for some rural areas we traveled to, but that was expected
