- ✓ Gives you a Chinese phone number (needed for some app registrations)
- ✓ Staff will help you set it up
- Requires passport registration (takes 10-15 minutes)

About VPNs
Google, Instagram, WhatsApp, and many Western apps don't work in China without a VPN. Some eSIM providers include VPN or tunnel through servers outside China. Check your provider's policy. Download and test your VPN before arriving — you can't download most VPN apps from within China.
