FUTURE TEXT MESSAGE
HI,
WHY THERE IS NO FUTURE SENT TEXT MESSAGE IN THE IPHONE?
WHICH MEAN THAT YOU CHOOSE A SPECIFIC DATE AND TIME TO SEND THE MESSAGE AND THEN IT CAN BE SENT AUTOMATICALLY FROM THE IPHONE.
This is a user-to-user technical support forum so we don't know for certain why things are the way they are. If you do an internet search (e.g., google) for "schedule text messages iPhone" you will find one or more 3rd party apps that do that. If you want to suggest that Apple make this a standard feature you can make a suggestion at https://www.apple.com/feedback/
