Czech Republic uses the Czech koruna

HelloRoam eSIM vs UK roaming charges in Czech Republic

A practical comparison of mobile data options for your Prague break.

Recommended

Typical cost

From $5.00 total

Details

Plans start at $3.20. Buy before your flight, install via QR code at home, and land in Prague already connected on Vodafone or O2. No daily EU roaming charges.

Czech SIM card

Typical cost

$8.00–$20.00 total

Details

Available in phone shops near Prague Airport and in the city but requires time and passport to purchase. Czech tourist SIMs can be good value but involve hassle on arrival.

UK carrier roaming (EE, Three, Vodafone UK, O2)

Typical cost

$10.00–$20.00/day

Details

Czech Republic is in the EU so UK networks charge daily roaming fees. A long weekend in Prague with daily EE or Vodafone UK charges adds to your bill. A HelloRoam eSIM avoids this.

Prices approximate as of April 2026. Actual savings vary.

Best time to visit Czech Republic from the UK

Prague is popular year-round with British visitors. Spring (April to May) is excellent with temperatures of 12°C to 20°C and flowering gardens. Summer (June to August) is warm at 22°C to 28°C with long evenings perfect for al fresco beer gardens in Prague. Autumn (September to October) is beautiful with fallen leaves and comfortable temperatures. Prague's Christmas market (late November to December) is one of Europe's finest and a major draw for British weekend breaks. Winter can be cold at 0°C to 5°C but the city is magical under light snowfall.
