I used to buy it on websites, but this time I bought it through Trip and it turned out to be very profitable. The internet worked in Turkey, France, and Greece, I’m very happy.

I took the eSIM on a trip and was very pleased. Internet was available almost immediately after activation, the connection is good, and everything works as expected. Maps, messaging, and navigation worked flawlessly. Everything is great and convenient, especially when you're traveling to a new country.

I went to Portugal for a month and chose this eSIM. The 50g plan was more than enough, and I even had almost half left. I used it as usual—maps, social media, and instant messaging. The signal and connection are always 10 out of 10, even in the mountains.

Had this sim in my trip in Italy and Greece. It worked in the places where even Italian operators didn't had a signal. In the opened sea I was the only person who had a line. Highly recommended

There were three of us traveling, and I took three SIM cards. It was convenient, and everything worked flawlessly in all the cities we visited. Customer support responded quickly and resolved the issue.

In Europe, eSIM with a mobile number and call functionality is the cheapest option. You can connect immediately at Budapest airport, but in hotels in Budapest, Zagreb, and Ljubljana, the internet speed is either very slow or impossible to connect at all. Outdoors and in the suburbs, there are generally no problems. I haven't used the call functionality, so I'm not sure. If the hotel offers free Wi-Fi, it's a cost-effective choice.
