Earlier in December 2013, Glo unleashed another "bumpa" tariff plan called glo Bumpa, this tariff plan gives subscribers 200% bonus upon recharge of credits from as low as #100. This new tariff plan is coming at a time Glo customers like me are yet to get enough of the Glo Bounce tariff plan which is targeted at youths and students that just want to get the best value for their money.
