SMS texting vs iMessage

[seansps]

I just noticed you updated your script to send a text already (I did it manually.)
In my testing locally I had to do something like the following to actually send a message with SMS:

tell application "Messages"
    send "A new Amazon Fresh delivery window is available!" to buddy phoneNumber of service "SMS"
end tell 

The other method seemed to only work for iMessage contacts and not SMS messaging.
