What travelers say about Roamix
“Bought my plan while waiting for my bags in Denpasar. By the time I walked out of the airport, I was already calling my driver. 10/10 service.”
Essential for digital nomads
I've tried every eSIM provider and Roamix has the most stable connection. I worked from a cafe in Lisbon for a week using just their data. Highly recommend.
Game changer for travel
Super simple interface. I'm not tech-savvy but I had this set up in under 2 minutes. The 5G speeds in New York were incredible.
Outstanding support
Had a small issue with my setting and the support team replied in under 5 minutes. They actually know their stuff. Truly impressive.

Czech Republic eSIM FAQs
Quick answers before you go.
A Czech Republic eSIM is a digital SIM that gives your phone mobile data in Czech Republic, with no plastic card to swap. You buy it online, scan the QR code we email you, and your phone connects to a local network as soon as you arrive.
Scan the QR code from your email or your Roamix account in your phone's settings, ideally at home on Wi-Fi before you fly. When you land in Czech Republic, turn on data roaming for the Roamix line and you're online.
Yes. Your usual SIM stays in your phone, so calls, texts and WhatsApp keep your number. Roamix runs alongside it as a second line just for data in Czech Republic.
