For example N100 recharge gives a 200% bonus airtime valid for 3 days while N200 to N999 recharges gives you 200% bonus airtime valid for 7 days and any recharge from N1000 and above gives a 200% bonus airtime with 1 month validity period.
These were how the Glo bumpa plans and their designated recharge and bonus validity period was initially designed, but the information just reaching us has it that Glo has made a tweak to the validity period of Glo bumpa bonus of N1000 and above recharges.
And the tweak was a reduction in the validity period of the bonus for the Bumper N1000 and above recharges; now instead of the normal 1 month validity period for N1000 and above recharges, they now carry a 7 day validity period.
What that entails is that those on Glo bumpa plan that recharge with N200 and above now will have a 200% bonus with 7 days validity period and others that recharge with N100 will have their bumpa bonus valid for 3 days.
Note that other benefits of Glo bumpa plan include free night calls and Glo subscribers will to migrate to the bumpa tariff plan can easily do so by dialling the code *100*10*1# and then replying with 1 to confirm migration.
