For me yesterday, calling on my MTN zone was a mini-nightmare. When I first saw 40k per seconds for calls, I thought it was a joke. I dialled again and the same thing.
For the whole day, MTN surprised me with 40:00k per seconds for calls on MTN zone and you can imagine how much I had to spend on calls for that amidst groans and sighs.
Thank you o MTN for the surprise.
who else got the surprise

none

me and I

In a country where you can't just faithfully stick to a network, multi choice is advisable- Etisalat and Glo to the rescue.

I was thinking i am the only one zone's charging 40kobo per second. It's not been funny since 2 days ago. I'm used to 4k and 8k per second. Mtn should do something asap!
