I don't see the "schedule" button anywhere on the phone like the instructions say. Is it not available on the Turbo?
What version of Messages + do you have? V. 5.6.6 has the scheduling ability - - compose a message, then long press the Send arrow for scheduling options. The specific phone shouldn't matter, it's the updated version of Messages+ that you need.
I have 5.6.6 (the most recent from earlier this week). I tried that.
Doesn't work

Note these instructions that indicate you must be subscribed to Integrated Messaging:
SCHEDULED MESSAGES
I missed that and now I have my answer. Thank you very much!
