Short code messaging
I am trying to send a message to short code 64600, from my iPhone XR, and it always immediately shows "Message Not Delivered." I have enabled SMS messages in my settings. Can you help me to get this to work?
Thanks - Mike

Good morning @MichaelHoke,
Allow us to lend a helping hand. Is this happening with any other contacts? When did this issue begin? Have you made sure that your device is updated to the latest software? Thank you.
Makaela, AT&T Community Specialist.
