UnionPay freezes short messages.

It's fake. You can call the customer service of the relevant bank. Most cases are false. The bank won't tell you anything about your account number by text message.

Bank card account freezing is generally not reminded. SMS reminders are mostly aimed at the increase or decrease of your account balance, that is to say, saving money, withdrawing money or transferring in or out. Freezing requires courts and procuratorates to go to outlets, and the balance will not increase or decrease.
