Sequenceable
```
public final class NetworkState
extends Object
implements Sequenceable
```
Records information about the network state of a device and provides methods for obtaining the information
Applications can obtain the following network state information:
- Operator name, including the operator name in the long alphanumeric format, operator name in the short alphanumeric format, and public land mobile network (PLMN) code
- Network status, including in_service, out_of_service, emergency_only, and power_off
- Roaming status
- 5G non-standalone (NSA) registration status
