Hi Shin;
At this time, PowerServer 2020 does not support SMS interaction with the App's host Mobile O/S. However, you could download and use a Cordova "plug-in" for this, for example: https://github.com/cordova-sms/cordova-sms-plugin
The above plug-in is not supported via the PS Mobile supplied Cordova PBL. So you would have to use PS's Cordova "Solution #2" approach and talk to this 3rd party plug-in via the ExecJavaScript () function. The argument passed to this command is jScript that can then access/update the plug-in's properties or interact with its methods. Please see the PowerServer Help for more information on this aspect.
HTH

I will check and test it.
