I suppose you're fixated on single connection plans. I'm paying ₹999+GST per month for 5 connections.
You can't really go over limit these days, and even if it happens you decide whether to be billed or have it stop access.
The best plan would be for you is the Jio 399 Family Plan (Base Price) + 99 (Per Member Fee) + GSTOk. Any such plans for 2 members or 3 atmost? Compared to current 3000Rs. annual 1.5gb unlimited plans (=max. 9000 per year)?

Calculations :
For 3 Members
85 GB Data with 200 GB Rollover
(399+99*2)+18% = 704.46/Month
For 4 Members
90 GB Data with 200 GB Rollover
(399+99*3)+18% = 821.28/Month
Benefits :
1. Data will not get expired unlike Pre-Paid and it will get carried over upto 200 GB + Upto 90 GB Monthly limit.
2. Postpaid Bill can be used as an address proof.
3. If you have a business then you can claim GST + Can treat the whole bill as an expense of your Biz.
4. Priority customer support and better network in crowed areas as there are separate towers for Postpaid.
