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.

For real!! This is a really cool eSIM card. I went to Belarus alone for a week, applied for it overnight, arrived in Minsk the next morning, connected via Wi-Fi at a coffee shop, and from then on, the internet was incredible. Every step of getting internet was very simple. I'll definitely use it again 🤲🏻✨

I used it in Montenegro and Serbia, and it connected quickly everywhere (though only after rebooting my phone). I got 1 GB per day, which is always enough for me! We went to the mountains in Montenegro, and even there we had no connection issues.

Unexpectedly, the network sometimes even worked in the Mediterranean, when we were out at sea for a day outside of ports. Onshore in Turkey, Italy, and Greece, there were no issues. The setup was simple, everything worked right away. 10/10.
