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.

Two countries, two completely different adventures, and one small travel essential—my eSIM! 🇮🇸🇮🇹 From exploring Iceland’s dramatic landscapes to figuring out transport in Italy, having mobile data made travelling feel easier and more independent. It’s easy to think about sharing beautiful photos, but the real value is in the practical moments: finding your accommodation, checking directions, or looking up an airport bus when you’re tired after a flight. No hunting for Wi-Fi whenever you need information. My favourite travel memories were Iceland’s ice caves and black sand beaches, but having the internet in my pocket helped with everything between those unforgettable moments. 📱✈️

Great price and zero hassle. I scanned the QR code, and it connected instantly upon arrival. The daily data allowance was perfect for navigating, messaging, and using social media without any drop in signal. Will definitely buy again for my next trip
