A text before the truck

The truck was already pointed at the address when the text finally went out.

Not because dispatch forgot. Because confirms still waited on whoever had a free minute after the morning scramble.

One reply came back wrong day. Another never came. By ten the board was a patch job and the office was on the phone instead of booking tomorrow.

You do not need a personality on SMS. You need one path that sends a plain confirm and reads the reply before the route locks.

If the text still chases the truck, start with an Audit on one visit type and when it gets confirmed.
