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 got 5GB, it's more than enough. I spent almost the entire day video chatting, sending photos and videos, and it handled everything perfectly. But for some reason, it wouldn't work at times. Sometimes I'd reconnect, but that didn't always help. Maybe the connection itself isn't that great in Venice. I haven't tried it in other cities yet. Even on the train, I had good reception.

The Esim card is easy to connect and works perfectly in several countries. I've purchased and renewed it several times, and the connection has never failed. Support responds quickly to questions. 10/10!

I used this eSIM in Serbia, Montenegro, and Bosnia. The reception was excellent everywhere, the connection was good. I had no problems. I recommend it.

Reviews: Orange World 4G/LTE eSIM | Calls + SMS | 31 Days Total 50MB–20GB | Calendar-Day Billing | QR code

We bought an eSIM for a three-week trip to the Seychelles. It worked 100%, never let us down. It also worked perfectly on the islands of La Digue and Praslin. It was easy to install, turned on upon arrival, and started working right away. Very convenient and great value. Physical SIM cards are very expensive in Mahe. I used it all day, checking Instagram, posting stories, and we didn't use up all the data in three weeks. We only used Wi-Fi in the evenings. So, I recommend it to everyone! Very easy, fast, convenient, and super affordable!

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.
