Thanks @twkrol for your contribution!

Would you be able to add tests and documentation for the newly added SMS backend? You can take the tests of the Twilio backend as an example, see:

django-sms/tests/tests.py

Line 216 in 0127d6c

class TwilioBackendTests(BaseSmsBackendTests, SimpleTestCase):

Please let me know if you need any help!

Ok, how to run the test locally?

After installing all dependencies you should be able to execute the tests using the python setup.py test command.

ready to go: documented & tested :)

Added a dirty thing: sending results, which I need to get after sms was sent (there is provider id of the message, status, etc)

    message.send_results = self.client.sms.send(
        to=recipient,
        message=message.body
    )

It works in real world, but the tests got it properly as error: there is no property of Message that could be set.

sms/backends/smsapi.py:54: error: "Message" has no attribute "send_results"

There are options:

• extend Message class (as many django libraries do, eg. anymail) to include send_results property
• another proposition to get sending status?

[twkrol]

What if we add to the Message class a property called, say: 'raw_results'
Then any backend implementation can include it's own send result there, but the interpretation is transferred to the programmer if she/he wants to use that data.
What do you think @roaldnefs ?
