Some providers have a limit on the length of the content. For example,
MSG91 has a 30 character limit and passing a longer value wil result
in an error:
DLT Template variable exceeded max length
As such, we're going to change the content back to how we had it before
1.5 when were were only sending the code by itself until we decide on
a better solution.
