How to buy Korean things online in China? I can't get the verification code.

If I can't get the verification code when I buy Korean things online in China, is it expired?

If the mobile phone can't receive short messages of certain numbers, it is suggested that:

1. If it's an official SMS from an operator, a bank or a group purchase, please try to resend it, check the status of the sim card, and restart your phone later to receive it again.

2. If it is a verification code, it is recommended to change to another location and try to send and receive it again to rule out whether it is caused by network reasons.

3. Change other time periods to receive again.
