Additional tip-
If you have any Rupay Platinum Debit card then using Amazon you can recharge the jio number and get 20% upto 100rs back once per month (only valid on fridays).
I use this to save around 80-90rs each month on jio recharge, basically still getting the plans at pre-hike prices.
BTW that offer is not limited to jio recharges but extends to all recharges and utility payments.
