I did the update to core-2021.8.3 and sending SMS works, Thank you, it's a good job to fix the problem. Receiving SMS is not working yet

I can confirm that sending SMS is now working. Great job. In log files there is only warning that only sending SMS is working and that current platform do not support of receiving SMS - just to notify you..

I have created a draft PR for the work to support incoming SMS. It needs a new version of python-gammu that incorporates this bug fix.
