CCB sends SMS to handle the authenticity of large credit cards.

I find it hard to believe. Stealing your personal information or something is still dangerous.

CCB's credit card application channels are generally CCB Credit Card official website, or CCB outlets, or mobile banking. I suggest you apply through official channels. The family is a big bank, and the quota is uniformly audited by a special department. Don't trust any big card. I feel unreliable when I listen to it.
