Why is the verification code information sent by online shopping yesterday missing today?

Please take good care of the verification code (within the validity period).

The validity period is generally indicated in the short message. The verification code is invalid after expiration.

If the information containing the verification code disappears, you should pay great attention.

First of all, think carefully about whether you deleted it yourself. Or see if it is blocked by the anti-harassment function of the mobile phone.

If not, then, be sure to kill your mobile phone and see if there is a Trojan horse or virus software.

Many of these types of malware can automatically receive, block and delete SMS messages. This will pose a great threat to our payment security.

I hope this answer can help you and be adopted.
