Does anyone know much about T-Mobile CZ? It seems like a good option, but
their web site is only in Czech, unlike O2 and Vodafone, which I guess puts off many temporary visitors.
Their
Twist SIM card seems like a good deal, particularly as it says "
Dobíjíte si, jen když potřebujete" (recharging only when needed), it's only CZK 200 (unlike O2) and you get free data with a new SIM card and top-ups.
