MTN has just gotten a bug on their network. So this will enable subscribers to access the Internet with only 20 naira sub for 20gig.
This is not like a cheat but a bug on MTN.
So I decide to post this for my blog viewers.

Make sure you are not on better talk or dial *406*1#  to migrate to mtn pulse. 

Just  dial *298*2*2#

Choose extra data choose 20gb for 20k that's number 8

And be given 20gb free

U must have at least #20

To check Your Balance dial *559*61#

If after being given and it doesn't work then you're one step away.
This step will cost you #300 and you're good to go.

Here is it *131*2*1*1#
Then you press 1 to confirm.
That's all
Enjoy while it last.
