Is there any computer software that can send short messages to mobile phones for free? It should be sent to Unicom number and mobile phone number, or it can be Unicom mobile.

If you look for a short message company, our company will cooperate with it. It's called Haiyan information technology. Anyway, your message for Haiyan should be found. I often send text messages. Although it is not free, it is almost free. A few cents, all mobile Unicom telecom users can send it, unlike Fetion, which can only send mobile messages ~

Code words are not easy ~ ~ ~ find some ~
