Hello, I have been looking around all over the place in search of a solution to the aforementioned problem. I have a Galaxy Note 3 N900P (hltespr) running stock 4.3 rooted.
I cannot seem to find a way to remove the "No Sim" car notification in the status bar. I do not have a SIM card as I got my phone in an auction hence the lack of data plan and SIM.
I have tried an Xposed module which supposedly removes the said notification...didn't work.. I also tried looking in the build.prop file to no avail. Usually a reboot removes the notification, but disabling airplane mode brings it back permanently.. even force-stopping the System Ui process removes the notification but it comes back shortly after disappearing.
Have you found any way to remove this annoying notification??
