We study phenomenological constraints on the simple 3-3-1 model with flavor-violating Yukawa couplings. Both Higgs triplets couple to leptons and quarks, which generates flavor-violating signals in both lepton and quark sectors. We have shown that this model allows for a large Higgs lepton flavor-violating rate decay 
and also may reach perfect agreement with other experimental constraints such as 
and 
. The contributions of flavor-changing neutral current couplings, Higgs–quark–quark couplings, mixing to the mesons are investigated. Br
can be enhanced acknowledging the measurements of meson mixing. The branching ratio for 
can reach up to 
, but it could be as low as 
.
