If the SMS is a fixed phone number, it is a fraudulent SMS, and this phone number is not CCB's credit card customer service hotline. Never call back. After calling back, ask for the card number, security code, expiration date, transaction verification code, and finally the card is stolen.
In addition, in this case, it is suggested that you can report this short message to the 1232 1 bad short message reporting platform, or you can install security software in your mobile phone and upgrade it regularly, which can effectively intercept phishing websites and nip in the bud.
