Is proton vpn working in china? Im travelling there soon.
Tldr, probably not. Proton has an article saying no, but that article is older than their new Stealth protocol which was built to work better in anti-vpn environments.
I would also read this article which has some information you may find useful.
Been to china, my advice is to amour up with a few vpn providers, and if you can get a sim card from Hong Kong, it gives full coverage in the mainland with western internet access
