We study a 3-3-1 model based on non-Abelian discrete symmetry group T13 which accommodates lepton mixing with non-zero θ13 and CP violation phase. The neutrinos get small masses and mixing with CP violation phase from SU(3)L antisextets which are all in triplets under T13. If both breakings T13→ Z3 and Z3→ \Identity\ are taken palce in neutrino sector and T13 is broken into Z3 in lepton sector, the realistic neutrino mixing form is obtained as a natural consequence of Pl and T13 symmetries. The model predicts the lepton mixing with non-zero θ13, and also gives a remarkable prediction of Dirac CP violation δCP=292.5^∘ in the normal spectrum, and δCP=303.161^∘ in the inverted spectrum which is still missing in the neutrino mixing matrix. There exist some regions of model parameters that can fit the experimental data in 2014 on neutrino masses and mixing without perturbation.
