Follow the steps below:
[STEP 1] Load the N200 glo airtime on the Glo sim you want to activate the cheat on. If you are on Glo bounce, you will be given 30mb free without touching the airtime.
[STEP 2] Quickly dial *127*124*1# and you will get an error message “INVALID APPLICATION”
[STEP 3] You just ignore it and dial *127*0# to check ur mb, you will see your 500mb but you will not be able to use it immediately.
[STEP 4] So you will have to remove your sim, and insert it back after 20 minutes.
You can now start using ur 500mb 30mb(if u are on bounce) =530mb. Insert your sim in any 3g network phone and start surfing the net and at the same time keep Downloading. Enjoy!!
