I just got a call, saying it was a telecom return visit, asking me if the card has been in operation for a long time and where.

Obviously, this is a fraudulent phone call. When you receive a call, you must pay attention to the content of the other party's inquiry, which involves money, account number, ID number, bank card number, personal privacy and so on. You must be vigilant. There are several ways to prevent fraudulent phone calls:

1. Tell your family not to trust phone calls and text messages from strangers. Maybe someone will cajole your relatives out of the house under the guise of your accident, or use your name to defraud property. When receiving suspicious phone calls and text messages, keep calm, don't panic, and discuss with family members, relatives and friends. Ask the staff of local police stations, bank outlets and telecom business outlets in person. 2. The number with the caller ID of "00 19" is an overseas call. 3. Criminals can set the calling number at will through software. Don't trust the caller ID number easily. The so-called "fixed telephone" provided by criminals is probably virtual phone who tied the criminals' mobile phones. No number display software supports callback. Even if the suspect calls with the number 1 10 or 10000, as long as you call back, you can't get through or transfer to the real unit. When you receive phone calls or text messages from relatives and friends, the phone number of the public security organ,1/kloc-0, 95598, etc. Ask for remittance, please be vigilant and verify in time to avoid property loss. The telephone of telecommunication and public security system is not the switchboard, so it is impossible to transfer calls between the two departments. Don't try to use unfamiliar banking services, such as ATM transfer or online banking. If necessary, you can consult the staff of bank outlets. 6. Don't reveal your bank card password. 7. No matter who the other person is, please be careful when asking about personal privacy. According to the law of our country, when investigating a case, the public security organs will not ask the people about their family savings accounts, passwords and other privacy by telephone. If you need to inquire about the case, you need to issue a work certificate and relevant legal documents and go to the relevant financial institutions to inquire. Public security police and tax bureau staff will not call to guide you how to transfer money and set passwords. It is also impossible for public security departments to provide so-called "safe accounts". 8. Don't believe the statement of car tax rebate. At present, there are only three kinds of car tax rebates in China. First, the purchased vehicle has quality problems and is returned to the sales manufacturer; Second, the purchased vehicles do not meet the relevant requirements and cannot be registered in the vehicle management department; Third, vehicles that are duty-free as stipulated by the state are required to return first. In this case, the owner needs to bring the relevant documents to the tax department for on-site handling, and it is impossible to operate remotely by telephone.
