Do I get 5G in Czechia?

Yes, where it has been built out. O2, TMobile, Vodafone run 5G in Czechia and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas.

How do I install my eSIM?

After checkout we email you a QR code. On your phone, open Settings, then Cellular or Mobile data, tap Add eSIM, and scan the code. Installation takes under a minute.

When does my Czechia eSIM activate?

Your plan activates automatically when you arrive and connect to a local network, so your validity period only starts once you land.

Can I keep my regular number?

Yes. The eSIM is data-only and runs alongside your physical SIM, so you keep your home number for calls and texts while using Viasimo for data.

Can I top up or extend my plan?

Yes. You can buy more data or extend your plan at any time from your account before it expires.

Does it support hotspot and tethering?

Tethering is supported on most devices, so you can share your connection with a laptop or other devices.

About this eSIM

A Czech Republic eSIM keeps you connected throughout the country, from the moment you arrive without roaming fees. Whether you're exploring Prague's historic old town square or wandering Brno's vibrant city center, you'll be online within seconds with one-tap activation and access to trusted local networks.

Coverage is strongest in Prague and across the bigger Bohemian and Moravian towns like Brno, Plzen and Ostrava, plus the main D1 motorway corridor. Signal can thin out in the forested Sumava and Krkonose mountains, in deep river valleys, and on backcountry hiking trails. Activate the eSIM once you land so you have data straight off the plane, and keep your home SIM active for calls and texts. Download offline maps of the old town before you go: Prague's twisty streets are easy to lose in.
