eSIM for Prague

Yes. Your Czechia eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are O2, Vodafone. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Yes, where it has been deployed. 5G runs on O2, Vodafone in Czechia, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

These are Viasimo's sizing recommendations, not measurements of your trip. Maps, messaging and the occasional lookup run to roughly 1GB a week. Streaming, video calls or tethering a laptop push that to 3-5GB a week, and uploading photos and video moves past it faster still. The data calculator on this site works it out from how you actually use your phone. Sizing one tier up costs less than topping up part-way through a trip.

Usually, though it depends on your own carrier. A roaming day-pass is charged for each day it is active whether you use the data or not, while a prepaid bundle is one up-front purchase for a fixed amount of data. The gap widens on longer trips. Check your carrier's published rate for Prague before you fly rather than taking our word for it.

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.

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