This statement doesn't t make sense. I assume you mean the contact is not having any problems with her iPad.

Can she iMessage with other iOS users?

Have you seen this?

If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support

Was she part of a group message at one point? There is a section in the support article that talks about what to do in that situation.
