Pick based on your trip
| Situation | Better option |
|---|---|
| 5–14 day tourist trip, modern phone | China travel eSIM (e.g. Airalo China eSIMs) installed before you fly |
| Need WeChat +86 SMS yourself | SMS-capable tourist SIM / special plan — not a generic data eSIM; or hotel desk receives codes |
| 24–72 hour transit | Airport/hotel Wi-Fi + light roaming, or a tiny eSIM pack |
| Work phone with negotiated roaming | Roaming, after you confirm China is included |
Setup checklist
- Confirm your phone is eSIM unlocked and not carrier-locked.
- Install the eSIM on home Wi-Fi; keep your home SIM for SMS from your bank.
- On landing, enable the eSIM line for data; leave roaming off on the home line unless you intend to pay for it.
- Test maps, DiDi and WhatsApp before you leave the airport Wi-Fi bubble.
Cost reality
Airalo’s China plans (China Unicom network) are commonly listed from a few USD for 1 GB / few days up to larger 15–30 day packs — prices move, so check the live catalog. Roaming day passes from US/EU carriers are often more expensive for heavy map use.
We may earn a commission if you buy through the Airalo link above (Travelpayouts). That does not change the price you pay. Official attraction tickets should still be bought on the channels in our guides.

FAQ
Will an Airalo China eSIM bypass the Great Firewall?
Many travel eSIMs for China advertise open access to Google/WhatsApp/Instagram. That depends on the provider’s routing — confirm in the current product description. WhatsApp calling still works for many visitors on hotel Wi-Fi even when cellular is restricted.
Can eSIM receive +86 SMS?
Often no. Most tourist eSIMs are data-only. For WeChat attraction SMS, prefer hotel-desk help or a physical China tourist SIM that explicitly includes SMS — see our SMS guide.
When is roaming better?
Short layover, corporate phone with a known China roaming plan, or if your device cannot install eSIMs. Check the per-MB rate before you land.
