Use multiple SMS apps simultaneously ?

Hi,

There are SMS apps that allow sending and receiving messages from desktop, and there are SMS apps that allow organizing conversations, but there aren't any that allow both, for free at least.

So, I would like to use two SMS apps in order to enjoy the best of both.

How to do that ?

If useful, I am rooted.

Note that I do not want to :

• Use one app per SIM ;
• Use KDE Connect or similar ;
• Constantly switch the default SMS app.

Thanks.
