eSIM Travel Tips for Prague

Get Online Before Leaving Václav Havel Airport
Install your HelloRoam eSIM at home before flying to Prague. When you land at PRG, your data connects on T-Mobile or O2 immediately. You can open Google Maps, Bolt, or the DPP Prague transit app in the arrivals hall. The Bus 119 from the airport to Nadrazi Veleslavin Metro has 4G throughout the route.
Book Prague Castle and Charles Bridge Sunrise Early
Prague Castle grounds are free to enter but the interior palaces and St. Vitus Cathedral require tickets. Book online before you go.

Network Coverage in Prague

Prague has 5G coverage in the city center and expanding 4G LTE across all city districts (katastrální území).

Old Town Square (Staroměstské náměstí), the Astronomical Clock, and the Charles Bridge have dense 5G and 4G from multiple operators. Wenceslas Square (Václavské náměstí), the main commercial boulevard, has excellent 5G.

Václav Havel Airport Prague (PRG) has 4G in both Terminal 1 and Terminal 2 buildings. 5G at the airport terminals is limited as of early 2026 but fast 4G is reliable. The Airport Express bus to Nádraží Veleslavín metro station has 4G on the surface route. The Prague Metro (lines A, B, C) has 4G at all underground stations. Prague is one of the few European metros with full tunnel coverage between stations on all three lines, enabled by the metro's distributed antenna investment.

Best Time to Visit Prague

Prague is a year-round destination, but April through June and September through October stand out. Spring brings mild temperatures (12C to 20C), the city emerging from winter, and Prague Spring International Music Festival in May. The Old Town Square Easter Market in April is one of central Europe's most colorful. Summer (June to August) is the peak tourist period. Temperatures reach 24C to 28C. The Charles Bridge and Old Town Square are genuinely crowded with walking tours and photography groups. Morning visits before 9am and evening walks after 8pm offer calmer experiences at the main sights. October has golden light, comfortable temperatures around 10C to 15C, and fewer tourists than summer peak. The Czech beer harvest in October and Burčák (young wine) events add a local seasonal dimension. December's Christmas markets at Old Town Square and Wenceslas Square are among the most celebrated in Central Europe, and January is cold (-2C to 3C) but historically the cheapest month to visit.
