My friend researching about cell phone development in India he needs to know about older plans exist in 90s and 2000s. Please post any news ads,plan brouchers or even sim card covers from that time. Even way back machine won't work since no one knows the older website names of airtel,escotel,skycell,Telstra,bpl mobile etc. So please help
