If you're intending to subscribe to above-mentioned promo, be aware of the following facts:
1. If you load N2000 for instance, you'll get a credit of N4000.
2. You can use the 4k credit to call any network including international ones.
3. The N4000 is in a single bonus account, unlike Glo's bonus whereby 2k is in Main account and 2k in Promo account.
4. This means you cannot use the 2k to subscribe to a data plan for instance.
5. You have to use up the 4k between Friday and Sunday evenings, otherwise you'll forfeit any remaining balance.
6. They don't like you to know the last 2 points because it makes the promo less appealing.
