What is the purpose of sending 5230-CN to 1069236603336?

It is to verify whether you are yourself and carry out future operations.

The short messages at the beginning of 1069 are some non-operating short message services, which mainly serve some third-party platforms and provide short message platform services for other enterprises, and only charge merchants, but the specific security depends on the content of short messages and everyone's situation.

I suggest that when you receive the short message from 1069, you should make a judgment according to your actual situation.
