Hello Jaya Prakas,

I have updated my previous answer, please do below change in your Rdata class and add [JsonProperty("3G/4G")] instead of [JsonProperty(PropertyName="3G/4G")]to your class.
```
 public class ResponseData
    {
        [JsonProperty("3G/4G")]
        public List<_3G4G> _3G4G { get; set; }

        [JsonProperty("2G")]
        public List<_2G> _2G { get; set; }
    }
```

Hello Jaya Prakas,

You can use below class to convert your json response to object,

 public class ResponseData
    {
        [JsonProperty("3G/4G")]
        public List<_3G4G> _3G4G { get; set; }

        [JsonProperty("2G")]
        public List<_2G> _2G { get; set; }
    }

    public class _3G4G
    {
        public string rs { get; set; }
        public string desc { get; set; }
        public string validity { get; set; }
        public string last_update { get; set; }
    }

    public class _2G
    {
        public string rs { get; set; }
        public string desc { get; set; }
        public string validity { get; set; }
    }

Note : add extra property as per your need in above class.

You need to convert your json object to class,

ResponseData responseData = JsonConvert.DeserializeObject(jsonString);

//After this you can assign you final class here


Response response = new Response();
response.Status = 1; // Status field should be boolean value, Your status return true value

response.rData = responseData ;
