I am not able to receive texts from only one number?

[AC Question]

I am able to send texts to my daughter's phone (have been doing so for 6 months) but cannot receive her return texts.

She in turn can receive my texts but cant text back. This started happening yesterday.

Neither of us have problems with anyone else.

To start with the simplest thing, has her number been blocked on your phone? See this link.
