What is your back-end database layer look like? If you're using LINQ (-to-SQL or -to-Entities), you could implement paging through WCF by specifying the page size and the page number you want, and then use LINQ's "Skip" and "Take" operators to fetch the page requested - something roughly like:

[ServiceContract]
public interface IFetchData
{
  [OperationContract]
  public List<Data> GetData(int pageSize, int pageNumber)
}

and then implement it something like this (simplified):

public class FetchDataService : IFetchData
{
  public List<Data> GetData(int pageSize, int pageNumber)
  {
      var query = yourContext.DataTable
                    .Skip((pageNumber - 1) * pageSize)
                    .Take(pageSize);

      return query.ToList();
  }
}

Would that be helpful for you??
