Should I get an eSIM, physical SIM, or use roaming in China?

For trips under 14 days needing unblocked internet: Hong Kong eSIM (bypasses firewall). For trips under 30 days needing a Chinese number: Chinese mainland eSIM or airport SIM. For 30+ days: Physical China Unicom prepaid SIM. For short business trips: Home carrier roaming (expensive but no setup).

Does my eSIM or SIM bypass the Great Firewall?

Hong Kong-based eSIMs and international roaming bypass the firewall. All Chinese mainland SIMs and eSIMs (China Mobile, Unicom, Telecom) are behind the firewall — you need a VPN. No exceptions.
