Hi Nairalanders,
what I dislike abou Nigerian Mobile Telecoms Network Provider (MTN) is their unsolicited sub-subscription and Auto-renewals they asign to their customer without their customers' consent!
Here are some please do feel free to add yours for other networks.

I just discover I have a caller-tune from MTN for over a year without knowing... So I decided to post this...

1. MTN Callertunz:
(Tips) To Deactivate; From your phone device Text CANCEL to 4100

2. MTN's EasyNet: which has option 1 to 7 categories; 1.Football, 2.News, 3.Gossip, 4.Fashion... 7.Cancel Auto- Renewal.
(Tips) To Deactivate ; From your phone device Dial *661# and the list appears and Do select the 7th option to deactivate or a particular category deactivate...

Sourced; do feel free to add yours... Thanks.

Thanks for the info. But the auto renewal part just annoys me.. Imagine i loaded 100 card on my phone(my last card).to make an urgent call. Immediately I received a text telling me "you have successfully renewed your "cash smash" costs #100 per day" but later I saw how to opt out and I VEHEMENTLY signed out now I can load my card in peace
