How to Call the Czech Republic from Australia: 3 Ways
Most people make calls to the Czech Republic in one of 3 ways.
- Calling card. You dial a local access number in Australia, so the card works from any landline or mobile phone. It needs no internet connection and no new SIM card. International rates to the Czech Republic start at 3.4c a minute.
- Your calling plan. Many calling plans charge a rate per minute for international dialling, and some block it. Check the rate to the Czech Republic before you call.
- Internet calling apps (VoIP). Calls are free when both people have the same app and a data plan or Wi-Fi. Call quality depends on the internet connection at both ends.
A calling card suits calls to landlines and to people with a weak internet connection.
Why a Call to the Czech Republic Does Not Work
- Adding a 0 after 420. The Czech Republic has no trunk prefix, so it is 0011 420 601 234 567.
- Dropping the 2 from a Prague number thinking it is an area prefix. It is part of the 9-digit number: 0011 420 212 345 678.
- Mixing up 420 (Czech Republic) and 421 (Slovakia). They shared code 42 until 1997.
- Assuming a 800 freephone number will work from Australia. It may not; ask for a normal landline or mobile number.
- Forgetting daylight saving. The Czech Republic is UTC+2 from the last Sunday of March to the last Sunday of October and UTC+1 the rest of the year.
- Your mobile plan may block international calls, or need extra credit for them. A phone card avoids this, because you dial an Australian access number first.
- On a phone card, the overseas number goes in after the access number and PIN, and ends with #.
