@lispud: Regarding the blue dot next to your contacts, this indicates that that they are able to send and receive messages in Chat mode. This may be what's interfering with your ability to send texts to certain contacts, therefore please head to the Messages app > Tap the 3 dots in the top right > Settings > Chat Settings > Select Default Messaging Type > Automatic > Resend Undelivered Chats > Send by SMS/MMS instead.
Messages that exceed 150 characters, or contain images, will convert to MMS format which requires Mobile Data to be active in order to send and receive them. With this in mind, please try enabling Mobile Data to see if this helps.

@lispud: Again, this may be related to the Chat Settings. Does he have a blue dot next to his name in your Contacts? Try temporarily disabling chat via Messages > 3 dots > Settings > Chat Settings > Advanced Calling and Messaging > Off, then send another text to your son to see if the issue persists.
