Trouble sending text to one specific person

Thanks for posting in the Apple Support Communities eap1995,

The following page offers some information that may help: If you can't send or receive messages on your iPhone or iPad

We're not seeing quite enough from your screenshot. Providing a bit more information and context, might increase the chances that you'll get a helpful response from the community.

Have you been able to send and receive messages from this contact before? Does the issue occur with other contacts?

Does this seem to be occurring with messages that would send as iMessage only? Or does it also occur with SMS messages?

Does this contact use an Apple device, or are thy using another type of device?

We'll look forward to hearing back from you.
