Seems Jio is unable to handle the traffic after getting users migrated/ported from other network especially once they turn to paid services. Recently recharged my plan with Summer Surprise package and m waiting for the network to act/react or show any signals of presence. Looks I may have to switch back to my previous operator once the validity of this plan is over(since I have paid for it, will keep my fingers crossed for it to get some speed at least).
