  We give two different approaches to classifying the simple modules of
$0$-Yokonuma-Hecke algebras $Y_{r,n}(0)$ over an algebraically closed field of
characteristic $p$ such that $p$ does not divide $r.$ Using the isomorphism
between the $0$-Yokonuma-Hecke algebra and $0$-Ariki-Koike-Shoji algebra, we in
fact give another way to obtain the simple modules of the latter, which was
previously studied by Hivert, Novelli and Thibon (Adv. Math. $\bf{205}$ (2006)
504-548). In the appendix, we give the classification of simple modules of the
nil Yokonuma-Hecke algebra.
