What is the free electronic insurance policy of Guangzhou Sino-American MetLife?

I got it, too It's the telecom attendant, saying that I installed broadband to insure me. I will receive a short message and download it, but I didn't receive such a short message. Today, I called again to say that my insurance policy came into effect, and I also promoted another insurance policy, with a deposit of 275 yuan/month for 5 years and a guarantee of 15 years. I don't want it. I think it's mainly for promotion. !
