Phone Icon in notification bar of S7 Edge

[Abdullah Intekhab]

For the past couple of months a random phone icon is appearing in my S7 edge notifications bar. This seems to have coincided with less than expected battery life. I'm not sure how this thing got here or how to get rid of it.

The icon looks like an old style phone receiver inside a white sim shaped box.

Please help.

Can you snap a picture to show us the icon? Also, is the icon 'actionable'? Is there a notification with it? If so, if you long-press the notification, can you see the app info?
