The pack is available for Rs 1,495 for existing users and Rs 1,494 for new users, and effectively brings down 4G data rates to Rs 50 per GB. The data pack will work on 4G handsets.
The company said "fair usage policy will be applicable on the data pack", which means consumers can avail up to 30 GB of high-speed data over 90 days and once this data limit is exhausted, the Internet will continue but on 2G speeds.
The pack is currently available in Delhi and will be launched across other circles over the next few days.
Reliance Jio, which launched its commercial 4G services on September 5, has promised its customers that they will continue to avail of free voice and data till December 31, after which voice calls will be free for life and data will be available at rock-bottom prices.
To ward off threat from Reliance Jio, incumbent operators including Airtel, Vodafone and Idea, have slashed data tariffs or announced promotional schemes that pack in more data for the same price.
