What people say about us...

ana87
I bought the eSIM for my trip to South Korea and honestly, 10/10. As soon as I got off the plane, I already had data—I didn’t have to do anything else. I got around Seoul using only Google Maps and it never failed me.
Carlos Mendez
I used it in Italy and Switzerland. It worked well most of the time, although it got a bit slow on the train—nothing serious. I’d still use it again because it’s more convenient than buying a physical SIM card.
Maru.Gonzalez
I’m not very tech-savvy, but it was quite easy to install. I followed the steps and that was it—I thought it would be more complicated. It worked perfectly for me in Paris for 12 days.
javier_t
I bought it for a business trip to the USA and honestly, super practical. I arrived, activated it, and was already connected. No crazy roaming charges or anything unusual.
Sofi L.
It worked well for me in Lisbon and Porto, but in a more rural area it took a bit longer to reconnect… still, it was very useful and I never ran out of data.
elmochilero_22
I used it in Thailand and Vietnam and honestly had zero issues. I uploaded photos every day and even made video calls. It’s great for backpackers.
Daniela paredes
The activation was simple, although I had to restart my phone once—I’m not sure why. After that, everything worked normally. Good speed for social media and maps.
Roberto Sánchez C.
This is the second time I’ve bought an eSIM for traveling (I used it in Germany before), and it has always worked well for me. I like that I don’t have to keep swapping physical SIM cards every time.
Lau_martins
The signal in Japan was quite stable, even in the subway. The only thing is that support took a while to respond to a query, but they did reply and resolved it.
AndresCallejero90
The best option if you don’t want to pay roaming. I bought it for Canada for 30 days and even had data left over—I was able to share internet with my girlfriend. Highly recommended, easy and quick to activate.
