Seek anonymous short message software or website, who has it?

On Android phones, it is recommended to use Secret.

Mi You software supports anonymous message sending and long message content. The recipient does not display the sender's mobile phone number, and the message received by the recipient shows that the sender is from Mi You, so it is impossible to reply.

I guess your friend didn't want you to know who sent it and sent you an anonymous message.

I'm also using this secret.
