eSIM vs Local SIM in Prague

Prague is an EU city, so EU SIM holders roam for free. For visitors from outside the EU, here is how connectivity options compare.

Recommended

Typical cost

—

Details

Buy before you leave home. Activate at home with a QR code. 5G active on landing at PRG Airport. Fixed pricing in USD. If you day-trip to Vienna or Berlin, check if a multi-country EU plan suits your itinerary better.

Czech local SIM (T-Mobile/O2/Vodafone)

Typical cost

—

Details

Czech prepaid SIMs are sold at PRG Airport, Alza shops, and telecom stores in the city. Prices start at CZK 199 to 499. No passport registration is required for Czech prepaid. Good value for longer stays but requires in-person setup on arrival.

Carrier roaming

Typical cost

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.
