1001001860 is the official number of China Unicom?

The thing is: I don't care because I basically don't read text messages now. Today, I received a phone call from a local uncle asking me to reply to a short message of satisfaction survey, with special emphasis on "10". I also asked two questions specially, and the answers were all right, which proved that it was not a recording. I thought about it. If it was a short message fraud, I should have received the verification code. This short message was sent to me the day before. If it was a scam, the system verification would have expired long ago, so I believed it. Nothing happened, reply if you want, and ignore if you are worried.
