Can I use PC version on my phone?

Yes.

how?

Depends on your phone and the browser you're using. I use Android, so I have Chrome as my browser. And there's a "Request desktop site" in the menu. Click that and it gives you the normal webpage, not the mobile webpage.

I can't find it. I'm trying to find for two years

For an Android :

It's in french, but the highlithed part is an equivalent of "Display computer version".

Firefox on Android also has the "request desktop site" functionality.

shit

There goes my 2 years
