Cell information Cell broadcast is designed to deliver messages to multiple users in an area. This is notably used by ISP to send Emergency/Government alerts. https://en.wikipedia.org/wiki/Cell_Broadcast https://www.androidcentral.com/amber-alerts-and-android-what-you-need-know I think this package only handles notifications for broadcasts, not the implementation. It seems like broadcast SMS use normal notifications so there is a chance this package provides special notification for Sony SMS app?
