After four years in the family business of edible oils and textiles, Chirag Patel wanted to do something different. "It occurred to me that there were numerous people who had email accounts but no computers of their own," he says. "They had to keep visiting cyber cafes to check their mail." Most of them, however, possessed cell phones. Thus Patel set up Net4Nuts, which has tied up with all the mobile company giants to provide email access to subscribers on their cell phones.
