Worked fine during our layover in Amsterdam. Now in Greece where the signal is also good. For the price, definitely worth it.

I recently traveled to the UK and was super satisfied with this 5G eSIM! 👏 5G speeds are fast, surfing the Internet, navigating, and finding restaurants is completely zero pressure. Watching videos and live streaming is super smooth, no lag at all📱✨ The best thing is that it is ready to use, scan the QR Code in a few minutes to get it done, no need to change the physical card, get off the plane immediately have the Internet, super convenient! The overall experience was very good, good value for money, sincerely recommended for a trip to the UK!

An excellent card, very convenient that you don't have to go anywhere to get a physical SIM card. Easy to install, economical to use, and the price is a steal.

To put it mildly, it was fantastic. First of all, the price was low, and I was able to travel around Italy without stress by choosing a plan with 1GB of data per day. Setup was also very easy, and the excellent support that Trip.com offers meant I could buy with peace of mind knowing there was someone I could rely on immediately if any problems arose. I would definitely use it again the next time I go to Europe.
