Why are there so many harassing calls from the secondary card?

Maybe you use the secondary card to associate various "services", download more software and visit more websites. Or the agency that sells your secondary card also "takes care" of you. So there are many opportunities for your number to be "wholesale". Another possibility is that the user of the secondary card has a poor sense of responsibility, or the probability of minors is high. Generally speaking, the anti-fraud ability of secondary card users is worse than that of primary card users. Therefore, the price of the secondary card number will be better than that of the main card. There are more people who are good at selling and collecting. Since "invested", we must pursue economic benefits. So I've been harassing wholesale. Wholesale and harassment. No choice but to tell the secondary card users not to answer the phone calls of strangers. Don't forget to blacklist or mark it as fraud. If you punctuate more, the liar number will be abolished. You can only buy one more number and the telephone company can sell one more number. You help him promote sales.
