10658686 is this the official mobile number? Same as 10086? Is some of the information he provided credible?

This information is credible. It is the number that China Mobile sends information such as business packages to customers. But it's basically useless It's just an official mandatory advertising number. I blacklisted him. Some scammers send SMS numbers similar to this. I suggest that if you really want to handle the business mentioned in it, you'd better first confirm whether there is that business in the labor service office of 10086.
