abstract fun onDataConnectionStateChanged(
    state: Int, 
    networkType: Int

Callback invoked when connection state changes on the registered subscription. Note, the registration subscription ID comes from TelephonyManager object which registers TelephonyCallback 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().
