How do you get a mobile phone number in the Czech Republic in 2026?

Buy a prepaid starter SIM or eSIM from O2, T-Mobile, or Vodafone at Václav Havel Airport kiosks, operator shops, Alza or Datart, or supermarket and Relay counters. Virtual operators such as Kaktus can be cheaper once you know what you need. Prepaid generally does not require rodné číslo or a Czech bank account, though a clerk may still glance at your passport.

Activate with an outbound call or the operator app, then top up. Online top-ups often prefer EEA-issued cards; cash top-up terminals and shop counters cover everyone else. Keep the packaging and ICCID until the number works for SMS codes used in bank onboarding.

Postpaid plans usually want identity checks and a Czech account for direct debit. Wait until residence documents and banking are stable: Paperwork after moving and Get rodné číslo. Ask the operator whether you can keep the same number when you migrate from prepaid.

Coverage is strong in Prague and Brno; rural valleys can thin. If you split time between cities, any of the big three is fine for urban life: Living in Prague and Living in Brno. Finish Foreign Police or MOI reporting with a working phone so appointment SMS can reach you: Register address.
