goText (Java apllication for your phone to send messages onver GPRS) has just received support to send messages to Czech Vodafone network. It is using public SMS gateway, the only drawback is that you have to detect captcha used on this page. But it still is cheaper than sending regullar SMS :-).
To use this service, add following URL to your goText services:
