get country code and sim operator name in unity ?

There are two steps:

  1. Locate a web service that you can call to request the information.
  2. In Unity, use the WWW and WWWForm API to make the request to the service you located in step (1).

Step 2 is pretty straightforward, and the API documentation should tell you all you need to know. Step 1 is outside the scope of what the Unity community can help you with.
