I can't transfer money, but I can send messages.

What you want to ask is why you can't transfer money but send a message? The other party has set privacy rights, and the WeChat version is too low. According to the inquiry, Zhongguancun Online official website shows:

1. If the other party sets the privacy right, it will lead to the phenomenon that the transfer cannot be made, but the message can be sent. Just contact the other party to close the privacy right.

2. If the WeChat version is too low, it will make it impossible to transfer money, but you can send a message to update the WeChat version.
