The best VPN to use in Shanghai is ExpressVPN. We used Astrill for a few years but recently stopped because:
- their payment systems were inflexible
- it is not easily adaptable to mobile devices
- speeds slowed down
- it stopped working on very regular occasion
- they have terrible or non-existent sales support
So we switched to ExpressVPN and it does a good job, especially on mobile.
We found that ExpressVPN was the best VPN for mobile phones in Shanghai as it was a very simple set up and it works well.
You can pay via credit card, Alipay or UnionPay, so it’s great for people in China also.
