Hi,
Thanks for the interest in our plugins. I can answer your questions.
We do not have any SMS or notification features for our plugins.
I’ve seen other users add a custom field to get a mobile phone number for SMS notifications. Then export that data to another plugin like Twilio, however this would be a lot of manual work on your end but essentially it is possible with this workaround.
If you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there.
