I always get calls asking me to change my credit card machine (pos machine). Is it a telecom fraud?

It is because the mobile phone number currently used has purchased pos-related products before, so just ignore it.

I often get calls from POS machines to change POS machines. Basically, I use my mobile phone number to buy products such as POS machines or credit card machines. Later, when user information was leaked, I was always harassed by the sales organization. Such institutions generally use words such as "free gift", "low rate" and "fake one loses ten" to attract users to change POS machines.

This kind of phone call is not a fraud, but an excessive pyramid scheme, which has harassed everyone's life. So after receiving this kind of call, you can directly refuse to answer or hang up. Don't talk too much with customer service, or you will be listed as a "potential user" and continue to be harassed.
