Why don't I get text alerts?

[iMore Question]

I am not getting text alerts when only one of my contacts texts me. I get alerts for games, facebook messages and every other contact, I just don't get alerts for one contact. Everything was fine a couple of days ago, and I have not changed anything to cause this to happen.

Check this contact card to make sure you have the contact turned on and a sound assigned to it.
