Maxxina: a few years ago there were a lot of websites where you could send sms for free ... about a year ago i wanted to find such a site again ... but couldnt find any which was totally free .. often you had to purchase another service and would then get the sms for free

but i think i found one site which offered 10 free sms per week for free, where you could sign up for free ... i forgot which site though (it was a dutch site) .. i will have a look if i can find it

i wrote myself a program which could send sms .. it encoded the message to the sms format (plus a few control characters) .. made a modem connection to an sms server .. send the message .. receive the answer from the server .. and break the connection

it used a dutch sms server .. but i guess it would work in czech as well when you know the phone number of an sms server there

last time when i tried my program it didnt work though .. but that might have been because i tried to make it work via an isdn modem line
(the traffic controllers we make still use the same sms server and it still works)

my program is written in visual basic 6 .. if you want i can send it to you via email
