While the plugin itself is open source, the service behind it relies on Twilio, and thus requires a commercial purchase before the plugin will work.
That said, I’d be happy to offer a 3-month promo code so you can try out the service. I can see you have a long history of contributing to plugin discussion, and I’d value your opinions and suggestions.
Just email “dan (at) danhulton (dot) com” and I’ll send it your way.
Thanks!
