eSIM or physical SIM for China travel?

eSIM — Pros, Cons & Best Providers

Pros: Buy online in 5 minutes, activate before landing (QR code), no store visit, no passport needed, instant connectivity, multiple plans available, keep your home SIM active simultaneously (dual SIM).

Cons: Data ONLY — no Chinese phone number. Some apps (Didi, WeChat, Alipay) may want a Chinese number for verification but most accept foreign numbers. eSIM requires an eSIM-compatible phone (iPhone XS+, most recent Android flagships).

Top providers: Airalo (cheapest, ¥60–150 for 7–15 days, 1–5GB), Nomad (good coverage, ¥80–200), Holafly (unlimited data, ¥150–300 for 7–15 days, but speed throttled after 500MB/day).

Coverage: All major eSIM providers use China Mobile or China Unicom networks — 4G/5G coverage in all cities and most tourist areas. Remote areas (Tibet, Xinjiang mountains) may have limited coverage.

Setup: Buy online → receive QR code by email → scan in phone settings → activate (some activate immediately, others when you land in China). Takes 2 minutes.

Recommendation: eSIM is the best choice for 90% of travelers. Get it before you fly — you cannot buy eSIMs after landing in China (websites may be blocked).

Physical SIM — Pros, Cons & How to Buy

Pros: Chinese phone number (+86), which is needed for some app registrations (certain bank accounts, delivery apps, some government services). Better data rates for long stays (¥50–100/month for 20–50GB). Can receive SMS verification codes.

Cons: Requires passport (real-name registration mandatory in China), airport store visit (30–60 min wait), Chinese payment for top-up (Alipay/WeChat or cash), stores may have limited English. Plan cancellation is difficult.

Where to buy: Airport stores (China Mobile, China Unicom, China Telecom — all have counters at major airports), convenience stores (some sell SIM cards), carrier stores in city malls.

Cost: Tourist plans ¥30–80 for 7–15 days with 5–20GB data + some call minutes. Monthly plans ¥50–150. Data-only plans available.

Registration: Must show passport. The store staff will take your photo and register the SIM in your name. This is a legal requirement — no anonymous SIMs in China.

When to choose physical SIM: Stays >30 days, need a Chinese number for app/bank verification, heavy data user (better rates), or if your phone doesn't support eSIM.

Other Options: Pocket WiFi & Roaming

Pocket WiFi (mobile hotspot): Rent a device before travel (from companies like China Mobile, Klook, or local providers). Pick up at airport or receive by mail. ¥30–60/day for unlimited data. Good for groups or multiple devices. Requires returning the device.

International roaming: Your home carrier may offer China roaming. Check rates — typically $10–25/day for data (expensive!). Some carriers (T-Mobile US, Three UK) include free basic roaming in China (slow speeds). eSIM is almost always cheaper.

Public WiFi: Available at airports, hotels, cafes, and some tourist sites. But requires Chinese phone number for SMS verification in many places — which foreigners may not have. Also, public WiFi is not secure — use a VPN if accessing sensitive accounts.

Hotel WiFi: Almost all hotels have free WiFi. Works for basic browsing but may be slow or have firewalls. Use your own data for important tasks.

Dual SIM strategy: Best of both worlds — use eSIM for data (primary) + your home SIM for SMS/calls (roaming). This way you can receive verification codes from your bank and home services while having cheap data in China.

Recommendation: eSIM for data + home SIM for roaming SMS/calls. This is the most common and cost-effective setup for short-term travelers.
