Data Recharge Plan

What should the best jio mobile pack to recharge for someone like who uses very less data because uses wifi at home and needs mobile data very less only when goes out in market for sometime like for making upi payments.

I had one idea but not sjre if it will work or not, the idea is to recharge with talktime which has unlimited validity, and do a data-addon charge(it has validity of existing plan) which will also get unlimited validity. Let me know if I am thinking correct??
