This is the second of three papers in which we study global convergence of iterations using linear information for the solution of nonlinear equations. In Wasilkowski  we proved that for the class of all analytic scalar complex functions having only simple zeros there exists no globally convergent stationary iteration using linear information. Here we exhibit a nonstationary iteration using linear information which is globally convergent even for the multivariate and abstract cases. This demonstrates the strength of nonstationary iteration. In Wasilkowski  we shall prove that any globally convergent iteration using linear information has infinite complexity even for the class of scalar complex polynomials having only simple zeros.
