Hi, pls try out my SMS broadcast freeware program. Popular download on Cnet.Download, can handle 50 messages at a time. Supports unicode/flash/blinking messages.

Have previously tried with Card Phone, but couldn't get the serial connection to work. Someone with the phone can try and if it works, please drop a message. Will appreciate, thanks! Meanwhile, it should work with Nokia 5110/6110 with data suite, 71XX and 62XX with data cable, and 82XX with infrared, at least some people managed to get it work with them!
