What is this icon with a messaging icon enclosed by a SIM card's icon in status bar? Can anyone tell me what the chat icon on the status bar is and how I can access it. This showed itself after a recent security update. I'm not sure if it's a message that I have not opened yet. I have checked all my messages and found none. Also, received messages are usually on the left side of the status bar.
It's a SIM icon.

To change it, go to Settings &rarr; Connections &rarr;SIM card manager &rarr; choose SIM1/SIM2 icon.
