Excuse me, where is the mobile phone number of 12?

Problem description:

5757 * * * 9 162. Send me a message at this number. I thought it was my friend, but she kept sending it. The content sent doesn't feel like those SMS platforms. I wonder if I am bound by my answer.

Analysis:

These are all short message platforms. If yes, what services have you customized? If you charge by the month or by the article, please call 10086 for manual consultation to cancel the related service, otherwise you will be charged all the time.
