abstract fun onMessageWaitingIndicatorChanged(mwi: Boolean): Unit
Callback invoked when the message-waiting indicator changes on the registered subscription. Note, the registration subscription ID comes from TelephonyManager object by TelephonyManager#registerTelephonyCallback(Executor, TelephonyCallback). If this TelephonyManager object was created with TelephonyManager#createForSubscriptionId(int), then the callback applies to the subscription ID. Otherwise, this callback applies to SubscriptionManager#getDefaultSubscriptionId(). The calling app should have carrier privileges (see TelephonyManager#hasCarrierPrivileges) if it does not have the android.Manifest.permission#READ_PHONE_STATE.
Requires android.Manifest.permission#READ_PHONE_STATE
