Czech Republic eSIM travel guide

Czech Republic's main mobile networks are O2, T-Mobile and Vodafone. Travel eSIMs connect through one or more of them, so coverage is usually good in cities and tourist areas and weaker in remote regions. If your SIM card is from an EU or EEA country, you can usually roam here at no extra cost under EU roaming rules.

Fixed data plans are the cheapest choice for maps, messaging and browsing. If you use more than about 1.5 GB a day, compare the unlimited passes above.
