What software can I use to send short messages to my mobile phone for free?

The Fetion service launched by China Mobile Company can send short messages to friends for free, but only friends are required (this is to prevent others from malicious harassment), and the other party also needs to open Fetion! Fetion services in many provinces are free. Open your mobile phone, download a Fetion mobile phone software, or install Fetion on your computer to send it! In fact, it is unrealistic to send short messages for free, and Fetion also has a daily limit of 300! Even if there are other SMS software, there is a monthly fee for registration, because mobile companies are not fools and will not exploit loopholes in business and management!
