This interface is used to call back to your implementation as data is received.
The methods are called in the same thread that the SIMPlugin.run(Callback) method was invoked in.
Each method should return true to continue to process data.
Returning false will cause the SIMPlugin.run(Callback) to return.
Called when the connector is not getting data from the SIM.
But, you are still able to call methods on the connector to get data anyway,
it just might be stale data or what the SIM wants you to get when the SIM is not running.
