We propose a minimal extension of the Standard Model where neutrino masses are generated radiatively at one-loop level via Scotogenic scenario. The model is augmented with A_4 modular symmetry as a scotogenic and flavor symmetry. With minimal number of parameters, the model makes predictions for neutrino oscillation data, Majorana and Dirac phases, dark matter characteristics, and neutrinoless double beta decay.
