Quick Answer
A China eSIM with international routing is usually the simplest option for short-term foreign travelers who need Google, WhatsApp, Gmail, Instagram, and other international apps. However, not every China eSIM includes unrestricted access or a built-in VPN, so check the routing policy before buying and install any separate VPN before arrival.
Quick choice: use a travel eSIM with international routing for convenience, a local Chinese SIM plus a pre-installed VPN for a local number, or home-carrier roaming when reliability matters more than price. Also prepare the essential China travel apps before departure.
| Internet option | Best for | International apps | Main limitation |
|---|---|---|---|
| Travel eSIM with international routing | Most short trips | Often works without a separate VPN | Confirm coverage, routing and data allowance |
| Local Chinese SIM + VPN | Longer stays or local phone number | Requires a reliable VPN installed before arrival | VPN performance can vary |
| Home-carrier roaming | Simple setup and important SMS | Often available through roaming | Usually more expensive |
| Hotel or public Wi-Fi | Backup only | Restricted unless a VPN works | Less reliable and less private |
