Recently, there has been much interest in epistemic models of quantum theory. Nonlocality of a class of this model has been shown to follow even without Bell-like arguments involving measurement statistics [Phys. Rev. Lett 110 (2013) 120401]. We show preparation contextuality of any mixed qubit in all such models to demonstrate the nonlocal feature of any pure bipartite entangled state by invoking GHJW theorem.
