According to the description of the problem, this may be a credit card issued by the previous owner of the mobile phone number. At present, after many mobile phone numbers are discarded, operators will automatically recycle them according to conditions and then release them. This has resulted in some people who have new mobile phone numbers receiving some text messages inexplicably. It is not ruled out that it is a fraud. It is recommended that you call the Minsheng Bank credit card customer service hotline to report the problem and ask how to solve it.
