You can send the contact information separately, and be sure to send it to 123 as 1-2-3, that is, add a symbol in the middle, so that the system will not recognize it as a number or something.
Like this dating platform, if they want you to contact each other, there may be some restrictions. For example, when you click on the other person's head or contact him, you send him some messages or voices, which may be restricted. Then you can send them paragraph by paragraph, or use voice to see if you can send them.
