I used it in Asia before; it was significantly cheaper than buying it locally. The main thing is to read the instructions and follow them.

Excellent eSIM! I used it while traveling through Serbia and Montenegro. The signal quality and connection speed were excellent even when changing countries. Setting up was also very easy. It was my first time using an eSIM, and frankly, I was worried about how it would work! Turns out I needn't have been. Just follow the instructions.

I’ve used several eSIM brands, but Orange stands out for reliability and speed. Installation was straightforward, and the connection never dropped, even on trains between cities. It gave me peace of mind knowing I was always connected. Worth every penny.
