  Two models with $SU(3)_C\otimes SU(3)_L\otimes U(1)_N$ gauge symmetry are
considered. We show that the masslessness of the photon does not prevent the
neutrinos from acquiring Majorana masses. That is, there is no relation between
the VEVs of Higgs fields and the electromagnetic gauge invariance contrary to
what has been claimed recently.
