I got Jio SIM from 2014 end itself. Before that, I was using Airtel Corporate Postpaid connections, with all numbers except me n family members using "RainMaker 199 Plan". It has CUG calls FREE, 300 SMS FREE, 800 minutes Local calls FREE. My family members are using Rs349 CUG plan, which is again same like the prev plan, but with 1GB of 3G data additional. They have UL WiFi in Home, ADSL 8Mbps plan for around Rs2000 per month, so 1GB was enough to use outside home.
I was personally using "Solitaire 1599" Plan, where 10,000 minutes of all calls (CUG/Local/STD/Roaming) FREE, 3000 SMS FREE (Roaming SMS chargeable - Stupid + Greedy Airtel), 8GB of 3G data FREE, all for Rs1599 + 18% STax. This was the only plan with FREE roaming calls in Airtel at that time.
The secondary number, I used was BSNL Prepaid, frankly I don't remember the plan. It was some 365 days valid plan, calls / SMS charged from TT Bal, (which I used to maintain high, for ISD purposes) and do only FULL TalkTime recharges for top ups.
So, yes JIO has done a revolution in Telecom for sure. Earlier I used to spend Rs2500+ per month, for my personal numbers alone. Now I am spending Rs2500+ per month, for all mine + family + staff numbers as a whole.
The Problem now, is rich people are getting more benefits than earlier and paying much less even now. Poor people are denied basic services for cheap Now. Middle class people are totally crushed. Earlier Poor people can maintain their number for at the max Rs150 (Min being Rs99 for incoming).
