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 used it well for the affordable price. On the last day, when I was traveling to the airport by car, the data didn't work, so I thought the e-SIM had already expired... but it seemed to work well at the airport, so it must have just stopped working in a specific area. Other than that, I used it well. Since the Wi-Fi at my accommodation and workplace was good, I only used 2GB out of the 7-day 10GB plan. I used it a lot at the airport haha.

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.

I use an eSIM when traveling around Europe, and it's very convenient 📱✈️ The internet works without having to buy a local SIM card or search for Wi-Fi. You can use Google Maps, Instagram, and the translator app, and always stay connected. It's a godsend for traveling around Europe 🤍
