So it depends on requirement, do you want no data cap cheaper or low data cap cheaper plans
currently unlimited 5g plan is only available at 899 or 3600
multiply by 4 = 14400rs yearly
postpaid 449 plan + 3sim 150x3 = 900+18%gst = 1062 x12M = 12744
you get unlimited 5g + 75gb + 3x5gb= 90gb 4g per month rolled over cap to 200gb
or 749 plan +3sim 150x3= 1199+18% = 1414 x12m = 16977rs
unlimited 5g + 100gb +15gb + netflix hd + prime
if you have good 5g coverage go for 449 postpaid one, so you can have unlimited 5g + no daily cap(max300gb per/month) and use 4g when traveling
jio has a cheaper postpaid family plan, but if you take Airtel Axis card with 25% upto 250rs cashback /month then airtel makes sense
1199 +18% =1414rs x 12 = 16968 - 250*12(3000) = 13968rs
unlimited 5g + 100gb + 30*3 = 190gb 4g + free prime mobile hotstar mobile appletv+ apple music and Airtel Xstream Play Premium (include sony liv and many other otts)
If you add airtel fibre with airtel postpaid it becomes Airtel black and gives 100rs extra off, Jio doesn't have any combo benefit.
All of above calculation is for 1+3sim plans
