As you might have noticed, I've been doing some research into GSM voice + mobile Internet in Africa lately. When comparing the results to prices in India, however, I was quite surprised.
Compared to the average price for a voice minute in Africa of around 10-15 Euro cents today, Indian carriers sell their voice minutes for around 2-3 Euro cents (taxes and recharge fees included, see an example of Airtel here and of BSNL here). Also, GPRS is much cheaper.
Assuming that the cost of running the networks in both regions is similar (just an assumption, please prove me wrong), I can't quite explain the difference. It's not missing competition, most African countries have 3 or 4 GSM networks today. It's not missing profitability either. EBITA of African and Indian wireless carriers are quite o.k. (see fore example the results of Airtel for 2008). Any ideas?
