In response to your concrete question, if you want to say text me - send me a notice - drop me a message or something alike, you can say:
But there are the expressions inform me - notify me - let me know as well. Then you could say:
It's not totally clear what the exact context is in your question, but I hope it helps.
As commenters noted, "Nachricht" means "message" and "Text" means "text", so you would be able to use the two words interchangeably where you only expect a message to be entered (since you can only enter messages that consist of text.) It's the same in English though.
