Switching between devices can be a bit tiring, I use to do the same in the past until I finally decided which device I liked better. I can certainly understand the importance of making sure your device is supported with a Dual sim card. When I took a closer look at the features in relation to the sim card, I'm only seeing that the device supports a 4G nano sim. To be sure ifthe device will ever support a Dual sim card, I would recommend reaching out to Samsung directly (800) 726-7864 to see if they will implement this feature with the Note 9 and any other future devices. I hope this helped provide more clarity.
