  We derive verifiable two-zero textures in the framework of a three-loop
induced neutrino mass model applying a modular $A_4$ symmetry for the lepton
sector. Interestingly, the neutrino mass structure is determined by assignments
of the right-handed charged-lepton particles only. We show all the possible
texture patterns and demonstrate their analytical and numerical analyses.
Finally, we mention a possibility of detection for doubly-charged boson via
colliders that decays into specific modes due to the flavor symmetry.
