I used O2 and was very pleased with the service at the shop and using it around Prague for a week.
O2's offer is 299 kc for 1.5 gb of 4G data. Coverage in Prague was great and it rarely switched to 3G. Maybe that happened twice in a week. It worked as well and although I forgot to check Speedtest, I never felt I was holding the phone long to pull up Google Maps. Only annoyance was that the prompts and messages they send you are in Czech and you can't change it to English.
TMo's offer is 300 kc for 500 mb of 4G data.
Vodafone was 400 kc for 1.5 mb of 4G data.
The exchange rate is about 25 kc per USD. No identification data was required to purchase the SIM.
Google Maps includes transit information for public transportation in Prague which was an added bonus. Loved being able to tram or subway all around the city. And we used Uber a few times, too! Not as many Ubers around in Prague so far but hoping it will continue to increase as they were much more affordable compared to the taxis.
Everything AmynM said (including about the Trams and Uber) is the same as I found it.
On my last visit at Easter I visited Prague and Pilsen.
My work phone had my UK Vodafone SIM in it with roaming activated and my personal phone had an O2 CZ SIM that I bought off eBay in advance.
On both cases, coverage and speed was great regardless of where I was.
What I have found however is that for eurpoean countries, try visiting the country website of Vodafone or T-Mobile before you get there. Often they detect you from being from outside the country and take you to a tourist page with full details of PAYG deals you can buy on arrival.
It's good to see that the carriers are now realising that people visiting a country will buy local SIMs so are trying to make it easy
For example, here is the Vodafone CZ PAYG page, all in english and nice and clear
