Can I use WhatsApp in China with an eSIM?

Yes, you can use WhatsApp in China with an eSIM, but you’ll usually need a VPN to access it reliably because WhatsApp is blocked on Chinese networks. The eSIM provides your mobile data connection, and the VPN encrypts and routes that data through another country so WhatsApp, calls, and media work normally. Install and test your VPN before you arrive, then connect it over your eSIM data whenever you want to use WhatsApp.
