Let me not bore you with my stupid introduction now let me cut the chase so the easy and simplest solution for accessing ISP blocked sites is by surfing through Tor browser ⬅ download from here

What is Tor?

Tor is free software and an open network which helps you to browse anonymously without getting tracked by location (or) cookies and help you surf the ISP blocked sites too

Anonymity matters

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world and it also prevents from somebody who is watching your Internet connection from learning what sites you visit, and then it prevents the websites you've visit from learning your physical location.
