去中國應該選哪種 eSIM？
最後更新 2026-06-02
What actually matters when choosing
- Routing: the listing should say it keeps Google / WhatsApp working in China (i.e. it exits the mainland), not just that it has China coverage.
- Phone support: confirm your phone takes an eSIM (Settings → look for the add-eSIM option).
- Data and days: match the plan to your trip length and how much you'll use; check whether tethering/hotspot is allowed if you need it.
- Price and top-ups: compare per-GB cost and whether you can extend mid-trip.
Watch out for local-breakout plans
A few eSIMs route your data onto the Chinese internet directly ("local breakout"), which means blocked apps stay blocked. Reputable travel eSIMs state plainly that Google and WhatsApp keep working in China — if a plan only names a local Chinese carrier with no mention of that, be cautious.
Routing behavior and which apps keep working can change between plans and over time. Confirm close to your trip, and test on arrival.
Before you fly
- Install the eSIM at home, but activate the data plan only when you land — most plans start counting from activation.
- Install one VPN as a backup and confirm it connects (you can't reliably download a VPN inside China).
- Download offline maps and an offline translation pack.
