👉 In a hurry? See our China eSIM Comparison table — every provider (Airalo, Saily, Holafly, Nomad, Ubigi, Trip.com, CMLink & local SIMs) side by side: data, price, validity, +86 number and firewall bypass.
1. eSIM vs physical SIM vs roaming — which should I choose?
| Use case | Best option |
|---|---|
| Trip 30 days, long-term | Physical China Unicom prepaid SIM |
| Short business trip, high budget | Home carrier international roaming |
Recommendation for 90% of tourists: Buy a Hong Kong eSIM before departure, plus a cheap Chinese mainland physical SIM if you need a local number for apps.
2. Which eSIMs work in China in 2026?
Firewall-bypassing eSIMs (Hong Kong-based, no Chinese phone number)
| Provider | Plan | Price |
|---|---|---|
| Airalo (HK Global) | 7d 10GB / 15d 20GB / 30d 50GB | $12 / $21 / $38 |
| Holafly (Greater China) | 10d unlimited / 20d unlimited / 30d unlimited | $27 / $45 / $62 |
| Nomad (HK Travel) | 15d 20GB / 30d 100GB | $22 / $42 |
| eSIM2Fly (APAC) | 7d 15GB (covers 10 Asian countries) | $14 |
Chinese mainland eSIMs (behind firewall, includes Chinese phone number)
| Provider | Plan | Price |
|---|---|---|
| Airalo (China Mainland) | 7d 10GB + 100 SMS / 30d 50GB + 500min calls | $8 / $25 |
| China Unicom official | 15d 30GB + 200min calls | ¥120 (~$16.70) |
Important: All eSIMs must be purchased and activated BEFORE you arrive in China.
3. Do I need a Chinese phone number?
You need one for:
- Registering new Meituan (food delivery) accounts
- Verification codes for some local booking apps
- Calling local businesses, taxi drivers, or hotel staff
You do NOT need one for:
- Basic internet access
- Using pre-registered WeChat/Alipay accounts (verified with passport)
- Booking train tickets on 12306 (supports passport registration directly)
- Using Amap/Baidu Maps for navigation
4. How to buy a physical SIM at the airport
All major international airports have dedicated tourist SIM counters in arrivals, open 24/7 for international flights.
What you need: Original passport with valid China entry stamp, cash or WeChat/Alipay.
| Provider | Plan | Price |
|---|---|---|
| China Unicom | 30 days 50GB data + 100min calls | ¥150 (~$21) |
| China Mobile | 30 days 40GB data + 50min calls | ¥140 (~$19.50) |
Activation takes 2–5 minutes. Avoid unofficial SIM sellers outside the official counter.
5. China Mobile vs China Unicom vs China Telecom
| Provider | Best for | English support |
|---|---|---|
| China Unicom | Most tourists — excellent coverage, good 5G | Best |
| China Mobile | Rural travel (Tibet, Xinjiang, mountains) | Limited |
| China Telecom | Southern China (Guangdong, Guangxi, Hainan) | Very limited |
6. Does my eSIM/SIM bypass the firewall?
Bypasses the firewall (Google, WhatsApp work without VPN):
- All Hong Kong-based eSIMs (traffic routes through Hong Kong)
- International roaming from your home carrier
Does NOT bypass the firewall (VPN needed):
- All Chinese mainland physical SIMs (China Mobile, Unicom, Telecom)
- All Chinese mainland eSIMs
- 99% of public WiFi
No exceptions: If your SIM is issued by a mainland Chinese provider, it is behind the firewall, no matter what the salesperson tells you.
7. What data speed can I expect?
- 5G: 300–800 Mbps download, available in 98% of urban areas
- 4G: 30–100 Mbps download, available everywhere even in small towns
- Rural areas: 4G standard, 5G at popular tourist sites (Zhangjiajie, Huangshan, Jiuzhaigou)
8. Can I use my SIM for Didi, Meituan, 12306?
| App | International number works? | Chinese number required? |
|---|---|---|
| Didi (rideshare) | Yes | No |
| Meituan (food delivery) | No | Yes |
| 12306 (train tickets) | Yes | No |
| Amap (navigation) | Yes, no number needed | No |
| Taobao (shopping) | No | Yes |
9. Dual SIM strategy
The best setup for most tourists:
- Slot 1 (home SIM): Keep active for 2FA codes from your bank, email, and home apps. Turn off data roaming.
- Slot 2 (Hong Kong eSIM): For unblocked internet, all daily browsing, social media, and navigation.
On iPhone: Settings → Cellular → Add eSIM. Set Hong Kong eSIM as default data line, home SIM as default voice line.
10. What if I'm staying longer than 30 days?
- Physical prepaid SIM from China Unicom: ¥80 (~$11)/month for 100GB 5G data + 100min calls
- Top-up via WeChat/Alipay (search "China Unicom" mini-program)
- Extendable up to 12 months with passport, no residency permit needed for tourist stays under 180 days
