What should I do if I am insulted by advertising messages?

Don't put that information in it. Usually it's a lie or a phone bill scam. You should ignore it and delete it. When you call China, it will either stop or the number doesn't exist, because it was sent by the software or the server. If a friend is looking for you, China won't ring and hang up ~ The message will say his name. Look at the text message carefully. Are there any advertisements and promotions when you are comfortable?
