It's best to call or text on the first date.

Hehe, I am a girl, too. I think it's better to send messages. Of course, be polite. Remember to send it on time every day. If the other party doesn't have a bad impression on you for a long time, it must have a deep impression. If you don't send it, girls will have a strange feeling and gradually like you. After a long time, you will naturally send messages early and become phone porridge, because you will not embarrass each other or yourself, and everyone can send letters to each other.
