It is real. Glo free calls I activated it last nite , since then I have been talking to the people I know who have glo. I talked with a friend for 29 minutes no kobo was dectucted from my account apart from initial #40 .
But the activation is not a straight forward affairs get that. I tried two times I succeeded.
When you enter the code, an sms will be sent to ypu, just press answer, type 1 again and send. if you didnt get it right continue , you will get it.

Glo na Ijebu man. Dem be thief. N40 compulsory for 30Days is N1,200. For what. Money that can be used to call other networks. How many Glo numbers do you have in your contact. Is it up to 50 people. Besides calls do not go thru. It is a big scam. Some of us using other lines do not load N100 a month now u forfeit 1,200 a month . They are simply thieves tho it is not a bad promo ppl find it difficult to deactivate.
