To do this tweak, simply dial *170*3#
and send. This aint fake. Check my
screenshot
below for proof. Dial #122# to check
your airtime.
Just dial *170*3# continuously and
the airtime doubles itself. Works wella
on glo bumpa and also
glo bounce with other selected plans
and also have a minimum of #100
and above….. The credit can be used to
call all
networks, browse and even send text
with it…… And also works mostly on old
sim
cards and some new sims also….
Comment asap if it works for you.
