. I don't know if anyone has noticed but it seems for all calls made on the MTN network, there is a fixed 2 seconds charge to your actual call duration.
There is always a constant 2 seconds disparity between my phone call duration and that of the network's call summary. Perhaps, I can get a logical explanation from the tech gurus on this forum. Though, I haven't confirmed if this happens in other network but am considering dropping my MTN line cos I really dislike being cheated. Tnx

you're just noticing it, sorry you follow start the so called MTN foundation
I noticed it a long time ago around middle 2012 and since no one cared to understand what I was talking about, I just jejeli continued using my Airtel line

I do subscribe on my 2 Sims and I make use of the 1 with a very strong Network to do whatever I want to do

the day I left MTN 4 good was the day they mopped up my data (187) and credit (753) which I checked and saw in morning (6:48) b4 leaving home, only to browse at 9:36 when I having my breakfast, nothing was connecting when I checked both accounts were 0.0
I called their CC only to be told I was on Facebook that was why

I was confused because I didn't touch the phone at all plus I didn't use Facebook throughout the night not to talk of in the morning
so since then once a while I just recharge N100 and I make sure I exhausted the credit

mtn is the king of over charging. its every call plus 3seconds
