General Information

The Czech Republic has 3 network operators:

  • O2 (owned by PPF, sold by Spanish Telefonica in 2013)
  • T-Mobile (owned by German Deutsche Telekom)
  • Vodafone (British-owned)

2G/GSM covers all of the country on 900 and 1800 MHz like in the rest of Europe. 3G/UMTS is on 2100 MHz in most of the areas. LTE:

  • 800/1800 MHz (O2) - available for prepaid.
  • 800/1800 MHz (T-Mobile) - not yet available for prepaid
  • 900 MHz (Vodafone) - available on some prepaid tariffs

O2 generally has the best coverage and speed nationwide, followed by T-Mobile and Vodafone as smallest network.


SIM cards are available in the stores of the network operators with photo ID or in many supermarkets. Recharge vouchers can be bought at many kiosks, post offices and petrol stations.
