Messages won't send or get delivered from one contact

Greetings darrinmjohnson,

If you are having an issue with receiving texts on your iPhone, I would suggest that you troubleshoot using the steps in this article - If you can't send or receive messages on your iPhone, iPad, or iPod touch.

In particular -

If your messages aren't sending, or you aren't getting messages

Check your contact information:

1. Make sure that you're using the right phone number or email address for the contact.
2. Go to Settings > Messages > Blocked and make sure that the contact isn't on your block list.

and

Restart your device and check for updates

1. Restart your device.
2. Check for a carrier settings update.
3. Check for an iOS software update.

Thanks for using Apple Support Communities.

Be well.
