eSIM vs local SIM in China: which is better?
For most short trips, an international **eSIM** bought before departure wins: it works the moment you land, and it routes you through your home network — so Google, WhatsApp and Instagram work without a VPN. A **local SIM** is cheaper per gigabyte and gives you a Chinese number (needed for some app verifications), but requires in-person passport registration at a carrier store.

Head-to-head comparison
| International eSIM | Local SIM (China Mobile/Unicom/Telecom) | |
|---|---|---|
| Price | Higher per GB (roughly $4–10/GB) | Cheaper (tourist packs from ~¥100 for 20–30GB) |
| Setup | Buy online, scan QR code before departure | Passport + in-person registration at a carrier store |
| Google/WhatsApp/IG | Work normally — traffic routes outside the firewall | Blocked unless you also run a VPN |
| Chinese phone number | No — data only | Yes (+86), needed for some app SMS verifications |
| Best for | Trips under 3 weeks, anyone who needs Google Maps/Translate | Long stays, business travelers, anyone needing a local number |
The eSIM catch nobody mentions
Travel eSIMs are data-only — no Chinese number, no SMS. A few services (some bank verifications, certain mini-programs) require a +86 number for SMS codes. If your trip depends on one of those, get a local SIM.
How to buy each one
- 1eSIM: buy from a provider like Airalo or Trip.com before departure, install the QR code on Wi-Fi, and activate on landing. Check your phone supports eSIM first (most phones from 2020+ do).
- 2Local SIM: bring your passport to a China Mobile/Unicom/Telecom store (airport stores have English service). Registration takes 15–30 minutes. Tourist SIMs are prepaid — top up at convenience stores.
One more option: roaming on your home carrier. It's the simplest (nothing to install) but usually the most expensive — check your carrier's China day-pass price before relying on it. For most travelers the ranking is: eSIM > local SIM > roaming.
