There seem to be a perception that MTN is leading Vodacom in terms of coverage.
EVERY single cell in Vodacom is GPRS enabled with a large number already on cs3/4 (MTN's GPRS+). I often get 60-70Kb/s on GPRS. So whomever has the largest network (I don't know) will have the biggest data coverage.
Furthermore EDGE is already widely deployed on the Vodacom network. This is probably one of the best kept secrets on the Vodacom network. I've asked Vodacom about this and their response was that EDGE is the end of an old technology while 3G is the future. So while they're rolling out EDGE, they prefer the market to move to 3G.
Then, of course, there's the 3G network that's rolling out rapidly. Read comments from V3G of more than 1500 base stations before year end. Vodacom also claimed in the press that HSDPA will begin testing this year. That will be Mb/s type of throughputs.
So while MTN is claiming a three-tier network strategy, it's already reality on Vodacom.
Without starting a war in this thread, I believe Vodacom currently has the better network. MTN should look at other ways to differentiate itself. I believe the forum's picked up on this and are looking at pricing as a potential differentiator.
