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 used an eSIM while traveling for work. I needed to be constantly connected, using messaging apps and accessing the internet. Everything worked out perfectly; the connection was good, and I encountered no major issues. It's great that you can set everything up in advance and go about your business without any hassle.

Excellent eSIM. I used it in the Netherlands, Belgium, and Turkey. The internet worked well. There was one outage, but support immediately provided a backup while they fixed the issue. I recommend it.

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.
