Just to get a clarification, you used VPN and yet you could not access your desired websites as Jio had blocked access to those sites? Is it another way of telling that using VPN would be less effective on Jio fibre?
No, access was blocked without VPN. I think they do deep packet inspection, so always better to use a VPN. Unfortunately, with Hathway too being majorly owned by Reliance, they are using the same back-end now and even Hathway keeps on injecting payment reminders on Indian websites.
