My mobile phone automatically sends text messages to 10663789 every day. I don't know what's going on. What's the number of 10663789? What business is 10663789?

10663789 is Shanghai Zhangjiang animation technology co., ltd.

Enter 0000 SMS and send it to 10086. 1 to 2 minutes later, you will receive a list of services you are enjoying. Just reply to the number before service. If it has been cancelled, you will receive a message "Service cancelled, welcome to use it next time" within 1-2 minutes. (Reprinted Qingling Ifaro's answer)

It may be that you ordered the business yourself, or that your mobile phone has a software charge. Download a 360 mobile phone guard to have a look. If not, call customer service and manual service.
