I saw this was missing an example on how to send an SMS (like the Python repo has), so I thought I'd throw this in there. Tested it on my setup and worked perfectly. It's just an example of how to send an SMS.
Added example of how to send SMS.
the example is good. but either remove the reference to the sandbox number or put the sandbox pin into the message to be consistent. then i will merge.
Modified SMS example to be consistent with the rest.
Is that more along the lines of what you were looking for?
