This was my first time using an eSIM. Among several vendors, I chose trifa because of its reliability as a Japanese company and 24-hour support. We used the 7-day plan for France. My husband was using an overseas SIM card, but my trifa was connected comfortably even in situations where the internet connection on his side was difficult. When I installed the eSIM before departure, I was panicked when I got a message like "it is not installed", but when I opened the support screen, I found out that such an event was happening and managed to solve it. The setup was easy, I didn't have to replace the SIM card and it was a breeze. The price is very reasonable and I am very happy with it! I will definitely use it for my next trip.
