I want to detect which sim card receives the sms. is it sim slot 1 or sim slot 2. is there any way?
As far as I know up to now there is no extension available which can do it
Here is a snippet
you could write your own extension and create the functionality yourself…
more information about how to create an extension see the App Inventor Extensions document however that will be more advanced and will require some Java skills…
