This paper focuses on the analysis of Whittaker modules and high-order Whittaker modules over the N = 2 super-BMS3 algebra. We provide a classification of Whittaker vectors and establish the necessary and sufficient conditions for Whittaker modules to be simple. Additionally, we study the simple quotient of the universal Whittaker module if it is not simple.
