Well, we got news that china is closing down on VPNs but here are some information regarding VPNs!
• There are some free VPN providers for mobile that seniors
use, e.g. Betternet, Hexatech and LanternVPN for
iPhone. These will be useful even if you have paid VPN
• ExpressVPN and Astrill subscriptions can support 3-5 devices at any point
of time, so you can share a subscription plan with your friends
• Download all the VPN apps and create VPN accounts BEFORE coming to
Shanghai, because you’re going to need VPN to download VPN once
you’re in Shanghai.
