There are three main operators in the Czech Republic: T-Mobile, O2 and Vodafone.

Some top tips from the staff

  • Czech is the official language of the Czech Republic. If you don’t know any Czech then you may want to download Google Translate onto your phone before traveling. However, the Czech Republic is very cosmopolitan and other languages are spoken too. English is taught in all schools and most people can speak it.
  • Locals call a SIM card a “karte” or a “SIM”.
  • Ask the retailer to set up your SIM card for you, they should know how to do it. If they can’t, follow the instructions we have highlighted above or go to the official operator website to get advice.
  • Remember, it’s always better to get things done early before the store get too busy. That way you are more likely to receive better assistance and avoid the crowds.

  • “If you arrive by plane, visit the Vodafone store at the airport or check the website. You can also visit the other providers in town, O2 and T-Mobile, which can be found in centers, for example, Vaclav Square or the Palladium Mall.”
  • “You can choose between three providers that operate in Czech Republic: O2, T-Mobile and Vodafone. The best thing to do is to visit the providers’ stores and check what they are currently offering.”

          Hi Mary,

          Thanks for your inquiry. You should be able to use your Verizon phone in Czech Republic if it’s a SIM-unlocked GSM phone. You can check your phone if it’s GSM or CDMA by looking up the phone’s model number. You can find this in the phone’s manual or your phone’s settings.
