Hi. I have info about operator for LJ TextMessages. It is New Telephone Company(NTC), Vladivostok, Russia. Main pages: www.vntc.ru, www.ntconline.ru, script for send SMS: http://www.ntconline.ru/sms/send.php method = post, additional info for send: prefix (7 digit lenght, 10 variations) and number (4 digit lenght, text input). I suppose that the limit is about 160 letters(or 70 when using cyrillic). Main form for text is located on www.ntconline.ru on the left side.
