Whatever site blocked, no need to worry. Just config your DNS to google DNS whatever site, SBF, Pornhub or what humsup site all immediate access. No need VPN or whatever also. Configure both on your PC & mobile browser all problem solved. This applies to all carriers. Try it to know. Even when recently the internet was down for many, I didn't know it was down cause all my devices DNS configured to the Google DNS long ago.
REPEAT: Do the settings for both your PC & Mobile phone & problem solved.
