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.

The only thing I'd note is that for very long-term use, you might want to consider other options, but for my frequent, but not always long, trips, this is the perfect solution. I'm very happy!

Before every trip, I had to go through the hassle of buying a local SIM card, searching for retailers, and wasting time on paperwork. Now, it's much simpler: I buy an eSIM in advance, install it, and I have a connection at the airport or upon arrival. This saves me a ton of time and stress, which is incredibly important for me as someone who's constantly on the go. For sailors who disembark in different countries, it's a lifesaver.

Whenever I ran into an issue, the response was quick and helpful. However, the service wasn’t always easy to use, as the connection was sometimes unreliable.
