An App to track and log SIM card status on Android phones
This app aims to track status of SIM acrd on Android phones.
It simply queries SIM status and logs them to Documents/GSMListener/GSMListenerLog.txt
This is a hastily written app to "debug" some real world problems observed by myself. Hence your milage may vary depending on your use case(s).
