Seeing the latest phone by Nokia and Sony in the market one wonders do i really need dem?? well here is a perfect formula to decide.
The capacity of mobile networks in your country can be ascertained by the price of the phones available. Case in point, the market as well as the networks in India are in no position to support even 2G services hence the best sellers in India tend to be Black and White phones be it Nokia 3315 or Nokia 1100.
So next time you see the ad of Nokia N 91, check out its price in terms of your local currency, if the cost of that phone is equal to 200 - 300 times the minimun denomination practically used (in India Rs. 10) go ahead and buy it, your networks can support it!!
