Picking a SIM card in most countries is a five-minute decision. In China, it’s a real choice with actual trade-offs — because the Great Firewall turns “which SIM” into “how do I even use the internet here.” Get it wrong and you’re either blocked from WhatsApp all trip or unable to call your Didi driver when they park somewhere unexpected.
Here’s the complete picture, with no fluff.
Short trip, mainly need internet: get a Nomad eSIM before you fly — it bypasses the firewall without a VPN. But note: on WiFi, the firewall still applies, so either carry enough eSIM data to stay off Chinese networks, or add Astrill VPN as backup. Staying 2+ weeks or needing Didi calls: get a local SIM from a city carrier store plus Astrill installed before departure. Best setup for most people: run both on a dual-SIM phone for around $22.
In China the right choice is important
In any other country, a SIM card is just data and maybe some calls. In China, the carrier you connect to determines which internet you’re on. Any SIM that runs on China’s domestic network — China Mobile, China Unicom, China Telecom — subjects your traffic to the Great Firewall. That means Google, Gmail, YouTube, WhatsApp, Instagram, Facebook, and most Western news outlets are blocked. Not slow — blocked.
An eSIM with Hong Kong routing works differently. Your data exits China before reaching your phone, so the Firewall never sees it. You get unrestricted internet automatically, the moment you land.
That’s a real advantage. But it only holds while you’re using eSIM data.
Switch to hotel WiFi, a restaurant’s network, or an airport lounge — and you’re back on China’s domestic internet. The eSIM’s firewall bypass doesn’t travel with you to WiFi. You either need enough eSIM data to stay off local networks entirely, or a working VPN installed before departure. Ideally both.
VPN provider websites are blocked. VPN apps are removed from Chinese app stores. Astrill must be downloaded, installed, and tested before you board. There is no in-country workaround.
What a China eSIM Actually Gives You
An eSIM is a digital SIM profile installed on your phone via a QR code — no physical card, nothing to insert. Most iPhones from the XS onwards and most flagship Android phones from 2020 support it. You buy a plan online, scan the QR code in Settings, and the carrier profile installs in seconds. You can do this at home before you leave.
What you get
Firewall-free 4G/5G data on eSIM. Instant setup before departure. Works the moment you land. Runs alongside your home SIM on dual-SIM phones. No passport required to buy.
What you don’t get
No voice calls. No SMS. No Chinese phone number. Firewall protection only on eSIM data — not on WiFi. Data-only, without exception.
The Phone Number Problem
This is where most eSIM guides stop before they should. No Chinese phone number means friction in specific situations that come up constantly on a China trip:
- Didi. Drivers call when they can’t find you — a wrong exit, a crowded drop-off zone, a gate number that doesn’t match. With no number to call, they cancel. This is a routine part of using Didi in any Chinese city, not an edge case.
- Chinese app verification. Many apps send OTP codes via SMS to confirm logins and payments — Meituan, food delivery platforms, ticketing sites, even some WeChat functions. With no Chinese number, there’s nothing to receive codes on. SMS from Chinese servers to foreign numbers is also unreliable.
- Hotel check-in. Some budget hotels and guesthouses ask for a Chinese contact number at check-in. Minor inconvenience, but worth knowing.
A typical scenario: a traveler arrives in Shanghai with an eSIM. WhatsApp, Instagram, Amap — all working perfectly. Then they try to order food delivery and hit an SMS verification wall. They flag a Didi to get to the next destination, the driver calls the foreign number, doesn’t bother redialing internationally, and cancels. Two out of three things they tried that day needed a Chinese number. The eSIM solved the internet problem but not the local integration problem.
eSIM Recommendation: Nomad
Nomad is the most straightforward eSIM option for China. Plans run on China Unicom and China Telecom, routing through Hong Kong. Setup is clean, pricing is transparent, and the fixed-data plans are more predictable than the throttled “unlimited” daily alternatives.
Nomad China eSIM Pricing — February 2026
| Data | Validity | Price | Best for |
|---|---|---|---|
| 1 GB | 7 days | $4 | Short layover or weekend |
| 3 GB | 30 days | $7 | 5–7 day light browsing |
| 5 GB | 30 days | $10 | One week with maps and messaging |
| 10 GB | 30 days | $12 | Two weeks — sweet spot |
| 20 GB | 30 days | $20 | Three to four week trips |
| 50 GB | 30 days | $35 | Extended stays or heavy users |
Install the eSIM profile at home but don’t activate it until you land. Nomad’s validity clock starts when the eSIM first connects to a network in China, not when you scan the QR code. You can have it sitting ready on your phone for weeks before your trip.
Comparing China eSIM Providers: Airalo, Saily, and Nomad
Three providers dominate the China eSIM market for foreign travelers: Airalo, Saily, and Nomad. All three route through Hong Kong and bypass the Great Firewall without a VPN. The differences are in price, network coverage, and how much data you actually get for your money.
Price and Data Side by Side
| Plan Size | Airalo | Saily | Nomad |
|---|---|---|---|
| 1 GB | $4.50 / 7 days | $3.99 / 7 days | $4 / 7 days |
| 3 GB | $11 / 30 days | $8.99 / 30 days | $7 / 30 days |
| 5 GB | $16 / 30 days | $12.99 / 30 days | $10 / 30 days |
| 10 GB | $26 / 30 days | $18.99 / 30 days | $12 / 30 days |
| 20 GB | $42 / 30 days | $28.99 / 30 days | $20 / 30 days |
Data Per Dollar
Price per GB tells you more than headline cost — especially once you move above the entry plans.
| Provider | At 5 GB | At 10 GB | At 20 GB |
|---|---|---|---|
| Airalo | $3.20 / GB | $2.60 / GB | $2.10 / GB |
| Saily | $2.60 / GB | $1.90 / GB | $1.45 / GB |
| Nomad | $2.00 / GB | $1.20 / GB | $1.00 / GB |
Connectivity and Coverage
| Factor | Airalo | Saily | Nomad |
|---|---|---|---|

| Voice / SMS | ❌ Data only | ❌ Data only | ❌ Data only |
| Hotspot / tethering | ✅ Yes | ✅ Yes | ✅ Yes |
| Top-up option | ✅ Yes | ✅ Yes | ✅ Yes |
| Track record in China | ★★★★★ Longest established | ★★★☆☆ Newer, less history | ★★★★☆ Solid, growing fast |
| App quality | ★★★★★ Best in class | ★★★★☆ Clean and simple | ★★★☆☆ Functional, no frills |
The Verdict
Airalo is the most polished experience and has the longest track record for China — if that peace of mind is worth paying for, it’s a legitimate choice. The app is excellent and support is responsive. You’re paying a premium for an established brand, and at $26 for 10 GB versus $12 on Nomad, that premium is real.
Saily sits in the middle. It’s backed by the same team behind NordVPN (note: NordVPN itself is blocked in China — Saily is a separate product and works fine), which suggests solid infrastructure. Less China-specific history than Airalo, but no reported issues. A reasonable option, especially if you find a deal.
Nomad wins on price — and it’s not close. At 10 GB it’s less than half the cost of Airalo for the same data on the same network infrastructure. The dual-network setup (Unicom + Telecom) gives a slight edge in coverage redundancy. The app is sparse but reliable. For a trip where you just need to stay connected without paying over the odds, it’s the practical pick — which is why it’s what I recommend and link to here.

What a Local Chinese SIM Gives You
A physical SIM from China Mobile (中国移动), China Unicom (中国联通), or China Telecom (中国电信) connects you to one of the fastest 5G and 4G mobile networks in the world. You get a real Chinese phone number. Didi drivers can reach you. App SMS verification works. Every service that expects a local number behaves normally.
The trade-off is the Firewall. Domestic network, domestic internet restrictions. You need a VPN — installed before you fly — to access Google, WhatsApp, and everything else that’s blocked. A passport is required by law to purchase any SIM in China.
Airport Counter vs. City Carrier Store
Most airports have China Mobile, Unicom, and Telecom counters in the international arrivals hall. Staff expect foreign passports, basic English is common, and you walk out with a working number in under 15 minutes. That convenience has a price: airport SIMs cost roughly double the equivalent plan from a city store, with fewer options.
A Unicom or Mobile storefront anywhere in a Chinese city sells the same network access for significantly less — often ¥50–80 ($7–11) for 10 GB over 30 days, compared to ¥150–200 at the airport for a similar tourist package. Staff at city stores also tend to be more thorough: they’ll configure your APN settings, check that data roaming is active, and fix anything that isn’t working before you leave the counter.
If you’ve downloaded Amap before flying (it works without a VPN, full English interface), you have offline navigation from the moment you land. Use hotel WiFi for the first hour, head to a city carrier store on day one, and save the ¥100+ difference. The only reason to buy at the airport is if you genuinely have no offline maps and need data immediately.
Which Carrier
China Unicom is the default choice for most foreign visitors. Tourist SIM plans are designed for international phones, band compatibility is broad, and city-center stores usually have someone who can manage in English. China Mobile is the better call for rural areas, western China, and anywhere off the main tourist trail — it has the largest physical network in the country. China Telecom is fine in coastal cities but noticeably thinner inland; not the first choice unless the other two have long queues.
If You Go Local SIM: Use Astrill
The only VPN that works consistently in China in 2026 is Astrill. Their StealthVPN protocol is built specifically to evade deep packet inspection — the technology China uses to detect and kill standard VPN traffic. At $20–30/month it’s more expensive than alternatives, and those alternatives mostly don’t work. NordVPN has been completely blocked since late 2025. ExpressVPN connects some months and fails entirely in others. Mullvad (€5/month, WireGuard with obfuscation) is the only budget option that’s proven reliable enough to mention, though it requires more manual setup.
Install Astrill at home, log in, and test a Hong Kong or Singapore server connection before your flight. Keep login credentials accessible offline. Once you’re in China on a local network, Astrill’s website is unreachable and the app cannot be downloaded.
The Full Comparison
| Factor | eSIM (Nomad) | Local SIM — City Store | Local SIM — Airport |

| Great Firewall (on eSIM data) | ✅ Bypassed automatically | ❌ VPN required | ❌ VPN required |
| Great Firewall (on WiFi) | ❌ Still applies — need VPN | ❌ Still applies — need VPN | ❌ Still applies — need VPN |
| Chinese phone number | ❌ None | ✅ Yes | ✅ Yes |
| Didi calls | ❌ Not possible | ✅ Works | ✅ Works |
| Chinese app SMS verification | ❌ No number to receive codes | ✅ Works | ✅ Works |
| Setup | ✅ At home before departure | ⚠️ City store, day one | ⚡ Airport on arrival |
| Cost (10 GB) | ✅ $12 | ✅ ~$7–11 | ⚠️ ~$20–28 |
| Data speed | ⚠️ Good, HK routing adds latency | ✅ Direct 5G/4G | ✅ Direct 5G/4G |
| Passport required | ✅ No | ❌ Yes | ❌ Yes |
The Hybrid: Run Both
Most iPhones from the XS onwards and flagship Android phones support Dual SIM — one physical card, one eSIM running simultaneously. The Nomad eSIM handles firewall-free browsing on mobile data; the local Unicom SIM provides a Chinese phone number for calls, SMS, and app verification. Both are always active, no switching required.
Total cost for a two-week trip: $12 (Nomad 10 GB eSIM) plus around $10 (Unicom city-store SIM) = $22. That’s cheaper than a single airport SIM. On iPhone, set the eSIM as default for cellular data in Settings → Cellular, and the Unicom SIM handles calls and SMS automatically.
You’ll still want Astrill installed for those moments when hotel WiFi is the only option and you need to check email — but with the eSIM covering your mobile data, you’ll rarely need it.
The Setup That Covers Everything
☑ Install a Nomad eSIM before your flight. Activate when you land.
☑ On a dual-SIM phone: also get a Unicom SIM from a city store on day one.
☑ Install Astrill and test a connection before boarding — for WiFi situations.
☑ Download Amap before flying. Works without VPN, full English, works immediately on landing.
☑ Whatever you choose: set everything up at home. China is not the place to figure this out for the first time.
Frequently Asked Questions
For short trips where you mainly need internet access, an eSIM is simpler — it bypasses the Great Firewall without a VPN and installs before departure. The catch: no Chinese phone number, which breaks Didi calls and some app verification flows. On WiFi the firewall still applies, so pair your eSIM with a VPN or keep enough data to stay off Chinese networks. For stays of two weeks or more, a local SIM from a city carrier store is better value. Running both on a dual-SIM phone covers everything for around $22.
Not when using eSIM mobile data — the Hong Kong routing bypasses the firewall automatically. But the moment you switch to WiFi (hotel, café, airport lounge), you’re on China’s domestic internet and the firewall applies in full. Either carry enough eSIM data to avoid Chinese WiFi entirely, or install Astrill VPN before departing as a backup for those situations.
No. eSIM plans for China are data-only — no voice calls, no SMS, no phone number. Didi drivers call when they can’t locate a pickup point, which happens regularly. Drivers who can’t reach passengers cancel the ride. For regular Didi use, a local Chinese SIM with a real phone number is necessary.
City stores are significantly better value — often half the price for the same data, more plan options, and more thorough setup. Buy at the airport only if you have no offline maps and genuinely need data before leaving the terminal. Download Amap before your flight and wait for a city store — the difference in cost and plan quality is worth it.
Yes, on any dual-SIM phone — most iPhones from XS onwards and most flagship Android devices. The Nomad eSIM handles firewall-free browsing on mobile data while the local SIM provides a Chinese phone number for calls, SMS, and app verification. Set the eSIM as your default data connection in phone settings and the local SIM handles calls and SMS automatically. Total cost for two weeks: around $22.
As of February 2026: 1 GB / 7 days is $4. 3 GB / 30 days is $7. 5 GB / 30 days is $10. 10 GB / 30 days is $12. 20 GB / 30 days is $20. 50 GB / 30 days is $35. All plans run on China Unicom and China Telecom networks and are data-only — no calls, no SMS, no Chinese phone number.
