Check your home plan first if your SIM is from the EU or EEA
Under the EU's "roam like at home" rules, a SIM from any EU country, Iceland, Liechtenstein or Norway can use its domestic allowance in Czechia at no extra charge, subject to your operator's fair-use limit. If that's you, a travel eSIM may only make sense for extra data or if your allowance is small. Since 1 January 2026 the rules also cover Ukraine and Moldova.
Subterranean Prague Metro coverage
Prague's metro system features full 4G and 5G coverage throughout its underground lines and stations through a joint infrastructure rollout by T-Mobile, O2, and Vodafone, ensuring unbroken connectivity while commuting.
Bohemian Switzerland and mountainous borders
While highways and towns have reliable high-speed data, hiking trails in national parks along the German border (such as Bohemian Switzerland and Krkonoše) may transition across international border towers.
