Quick Answer

For most first-time visitors, use a physical SIM card, not eSIM.
eSIMs are less compatible, harder to troubleshoot, and easier to misconfigure in China.
If connectivity matters for payments, navigation, and verification, physical SIM wins.

The Reality: Why eSIM Is Not China-Friendly

Despite marketing claims, eSIMs in China face practical issues:

  • Limited carrier compatibility
  • Inconsistent performance across regions
  • Harder APN troubleshooting
  • Poor support at counters and hotels
  • Higher failure rate for QR payments and ride apps

When an eSIM fails, you are usually on your own.

What Physical SIM Cards Do Better

Physical SIMs offer:

  • Stable local carrier integration
  • Predictable speeds and latency
  • Easier troubleshooting by staff
  • Better compatibility with payment apps
  • Reliable SMS reception when enabled

They are boring, but reliable—which is exactly what you want.

When eSIM Might Be Acceptable (Narrow Cases)

eSIM can work only if all are true:

  • Your phone is confirmed eSIM-compatible
  • You do not need SMS verification
  • You are comfortable adjusting APN settings
  • You accept that support is minimal
  • You have offline backups ready

If any condition fails, do not use eSIM.

Exact Actions: Choose the Right Option

Choose this if:

  • This is your first trip to China
  • You rely on mobile payments
  • You need stable maps and ride-hailing
  • You want easy fixes at the airport

Action: Buy from official airport counters or major carriers.

Option B: eSIM (Use With Caution)

Choose this only if:

  • You have used eSIMs successfully before
  • You have a backup plan
  • You are comfortable with technical setup

Action: Test activation and data before departure.

Setup Rules That Prevent Failure

For Physical SIM

  • Insert and test data at the counter
  • Load a map and a website before leaving
  • Confirm data speed is usable
  • Keep your home SIM if you need SMS

For eSIM

  • Activate before you fly
  • Confirm APN settings manually if needed
  • Test payments, maps, and messaging
  • Screenshot setup details
  • Carry a backup SIM plan

Never assume “it will just work.”

Failure Scenarios & Fixes

  • eSIM shows signal but no data: manual APN setup or switch to physical SIM.
  • Payment apps fail on eSIM: switch network or change SIM.
  • Cannot receive verification SMS: reinsert home SIM.
  • Airport staff cannot help with eSIM: buy a physical SIM immediately.
  • Connectivity drops in smaller cities: physical SIM performs better.

Troubleshooting eSIMs wastes travel time.

Reality Check

  • eSIM is convenient elsewhere, not here.
  • Physical SIMs are still the local standard.
  • Support staff understand SIMs, not eSIMs.
  • Stability matters more than elegance.

Choose reliability over novelty.

What Locals Do Instead

  • Locals use physical SIMs.
  • Locals keep one number stable.
  • Locals avoid changing network setups mid-trip.
  • Locals fix issues in person, not via apps.

Copy the stable approach.

Checklist

  • Decision made: physical SIM or eSIM.
  • If eSIM, activation tested before flight.
  • If SIM, data tested at counter.
  • Home SIM kept if SMS needed.
  • Offline maps and bookings saved.
