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.

Worked great in Italy, France, and Switzerland. No problems. Worked poorly in Monaco, I don't know why. Highly recommended!

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

Good coverage. Whilst other family members using different servers and do not get coverage, this sim is working fine. Not on the moving fast train, buy is understandable
