If the quota (number of sessions or duration) is used up, the usage is restricted and multi-network concurrency is automatically released. Your app can listen to the exit callback in netHandover.on('multiPathStateChange'). If the multi-network concurrency capability is requested again, an error code will be thrown. Your app can determine the error type by checking the error code in netHandover.requestMultiPath(). The quota information is updated every 24 hours.
