AppleScript code for adding Turkish international phone prefix to every phone item in Apple Contacts

convertToInternationalTurkishNumber.applescript

tell application "Contacts"
	repeat with i from 1 to (count every person)
		set phoneProperties to properties of phones of person i
		repeat with j from 1 to (count of phoneProperties)
			if value of item j of phoneProperties does not contain "+" then
				set oldPhone to value of item j of phoneProperties
				set value of item j of phones of person i to "+9" & oldPhone
			end if
		end repeat
	end repeat
	save
end tell

Keep in mind that this script will convert all non-prefixed numbers of your contacts to Turkish prefixed ones.
