Impressed by new eSIM

I don’t usually write reviews but was quite impressed by how good this eSIM was in Japan. I have used Airalo many times before but faced intermittent connectivity issues which is why I wanted to try something different. I had a much smoother experience with ZenSim. If you’re reading this, I’d recommend this eSIM :)
