Several options

Hi there,
Not sure if this answer is still useful to you, but it may be to others.
Plenty of hotels and other places (coffee shops, shopping malls) offer free wifi.If you really want a mobile internet for serious web browsing, check one of these options:
O2: 700CZK including USB stick (http://www.o2.cz/osobni/en/internet-on-the-road/178445-inte
rnet_kdyz_potreba.html)
Vodafone: 400CZK + USB stick (https://www.vodafone.cz/internet/internet-do-notebooku/ - in Czech only, sorry)
T-Mobile: 500CZK + 500CZK USB stick (https://www.t-mobile.cz/web/cz/osobni/internet/internet-na-
cesty/tarify-a-ceny - in Czech again)
Alternatively, you can connect via 3G using your phone and prepaid card from any of these operators.I assume the coverage would be similar for all - unless you go to a forest retreat or underground, you should be able to connect.
