Sadly doesn’t seem like it’ll help

Last month, China announced it would require an ICP license in order for apps to be listed in all mobile app stores. Now, as Apple honors the regulation, it closes a loophole that had let iPhone users in China download and, with a VPN, use apps that the government there has blocked for most or all of the country, like WhatsApp, Facebook, and YouTube.

You need to somehow download a VPN first and then somehow punchhole ISP’s restrict firewalls.

Normal VPN doesn’t work because China firewall uses deep packet inspection that looks for signs that traffic is being tunneled and then blocks the IPs involved. On the other hand, VPN use can land users in jail as well
