India’s mobile revolution started with one symbolic call on this day 20 years ago when the then West Bengal CM Jyoti Basu made the first mobile call to Sukh Ram, the then Union communications minister, on July 31, 1995 on B K Modi’s erstwhile Modi Telstra NW partnered with a sceptical Nokia to accomplish the impossible.

Barring basic commodities, no other product or service has a base of a billion consumers.
