The packs are very enticing but they have an FUP for lower priced packs which has more data than competitors but as a heavy user I cannot use it unconditionally. Also, their 4G service is very bad at many places as they have less towers. For example they have only 1 tower for 6KM radius where I stay so all the traffic goes through that 1 tower and the data speed is crawling during the day. If I connect late at night, it is fast. So, they have to give freebies so that people come on board even if the speeds are bad due to technicalities. But yes, they are more generous than Airtel or Vodafone or Idea.
