Getting online in China is not like getting online anywhere else. The Great Firewall blocks Google, WhatsApp, Instagram, YouTube, Gmail, and basically every app you rely on daily. Most travelers know they need a VPN. But here’s what fewer people realize: an eSIM can bypass the Great Firewall entirely on mobile data — no VPN app required.
That’s the killer feature. Because eSIMs from international providers route your traffic through servers outside China, the firewall never touches it. You land at PVG, toggle on your eSIM data, and Google Maps just works. WhatsApp messages come through. YouTube loads.
Two reasons to get an eSIM before your China trip:
- Skip the SIM card hassle. No passport registration at a carrier store. No language barrier. No wasted first morning. You set it up before you fly.
- Bypass the Great Firewall on mobile data. Your eSIM routes traffic through foreign networks. The firewall doesn’t apply. You get unrestricted internet on your phone without installing or configuring anything extra.
One critical caveat: eSIM bypass only works on cellular data. The moment you connect to hotel WiFi, cafe WiFi, or any local network, you’re back behind the firewall. You still need a VPN for those situations. We cover our top picks in our VPN guide for China.
The best setup for China in 2026? eSIM for on-the-go access + VPN for WiFi. This guide covers the eSIM half.
How We Tested
We don’t write eSIM reviews from spec sheets. Our team tested five eSIM providers across a two-week trip through Beijing, Shanghai, and Chengdu in February-March 2026. Here’s what we measured:
- Download and upload speeds using Speedtest by Ookla, tested at multiple times of day
- App access — Google Search, Google Maps, WhatsApp, YouTube, Instagram, Gmail, and ChatGPT
- Coverage reliability in metros, high-speed trains (Beijing-Shanghai G-train), inside buildings, and rural areas outside Chengdu
- Setup time from purchase to working connection
- Real-world usability — navigation, messaging, video calls, streaming
Every provider was tested on the same iPhone 15 Pro and a Samsung Galaxy S24, swapping eSIMs at each location. Speeds listed below are averages across multiple tests, not cherry-picked peaks.
Our Top Picks
#1 Holafly — Best Overall for China
Network: China Mobile (China’s largest carrier, best coverage) Data: Unlimited (fair usage policy applies) Speed: 30-50 Mbps download in cities, 10-20 Mbps in rural areas Built-in VPN: Yes Hotspot: 500MB/day tethering included
Holafly is our top pick for one reason above all else: it includes a built-in VPN layer. Every other eSIM on this list bypasses the Great Firewall because your data routes through foreign servers. Holafly does that too — but it also wraps your connection in VPN-like encryption, which makes the bypass more reliable and consistent. During our testing, we had zero instances of blocked apps on Holafly’s data connection. Zero.
The unlimited data is the other standout. You never have to think about usage. Navigate all day with Google Maps, send photos on WhatsApp, video call your family — it just works. There is a fair usage policy: if you’re hammering the connection with constant high-bandwidth downloads for hours, you’ll get throttled. In two weeks of normal travel use, we never hit the limit.
Speed was consistently the fastest of any provider we tested. We averaged 38 Mbps download in Shanghai’s Jing’an district and 42 Mbps near Beijing’s Sanlitun. Even on the metro, we held 15-25 Mbps on most lines. The Chengdu suburbs dropped to 12-18 Mbps, which is still plenty for maps and messaging.
Holafly runs on China Mobile’s network, which has the widest coverage in the country. This mattered most on the high-speed train between Beijing and Shanghai — we maintained a usable connection for roughly 85% of the journey, compared to around 60% on China Unicom-based providers.
Pricing:
| Duration | Price | Per Day |
|---|---|---|
| 5 days | $19.00 | $3.80 |
| 14 days | $47.90 | $3.42 |
| 30 days | $74.90 | $2.50 |
Setup: Purchase on holafly.com, receive QR code by email within minutes, scan and install the eSIM profile on your phone. Do this before you leave home. Don’t enable data roaming until you land in China. The whole process took us about four minutes.
Pros:
- Unlimited data — no usage anxiety
- Built-in VPN for the most reliable GFW bypass
- Fastest speeds in our testing
- 5G support in major cities
- China Mobile network (best coverage)
- 24/7 English-language chat support
Cons:
- Pricier than Airalo, especially for short trips
- Fair usage throttling kicks in under very heavy use
- No local Chinese phone number (you can’t receive local calls or SMS)
- Does not work in Hong Kong — you need a separate Holafly plan for HK
Best for: Most travelers who want the simplest, most reliable option and don’t mind paying a bit more for peace of mind.
#2 Airalo — Best Budget Option
Network: China Mobile or China Unicom (varies by plan) Data: Limited plans (1GB to 20GB) and some unlimited options Speed: 15-35 Mbps typical download VPN: No built-in VPN, but most plans bypass GFW via foreign routing
Airalo is the biggest name in eSIMs globally, and for good reason — the app is excellent, the plan selection is huge, and the prices are hard to beat. For budget-conscious travelers or short trips, it’s the smart pick.
A word of warning, though: not all Airalo plans bypass the Great Firewall equally. We tested three different Airalo China plans. The China-specific plans routed through foreign servers and gave us full access to Google, WhatsApp, and YouTube. But one regional Asia plan we tried routed partially through local servers, and Google was intermittently blocked. Stick with plans labeled specifically for “China” in the Airalo app, and you should be fine.
Speeds were solid but a step below Holafly. We averaged 22 Mbps in Shanghai and 28 Mbps in Beijing on the 10GB plan. Enough for everything except heavy streaming. YouTube loaded fine at 720p; 1080p buffered occasionally during peak hours.
The data caps are the main tradeoff. If you’re a light user — maps, messaging, occasional browsing — a 5GB plan will last a two-week trip comfortably. If you’re streaming video, posting to social media constantly, or tethering to a laptop, you’ll burn through data fast. Monitor your usage in the Airalo app, which tracks consumption in real time.
Pricing:
| Plan | Duration | Price | Per Day |
|---|---|---|---|
| 1GB | 7 days | $4.50 | $0.64 |
| 5GB | 30 days | $16.00 | $0.53 |
| 10GB | 30 days | $26.00 | $0.87 |
| 20GB | 30 days | $42.00 | $1.40 |
Setup: Download the Airalo app (iOS or Android), browse China plans, purchase, and install the eSIM profile directly from the app. The guided setup is the best of any provider we tested — clear instructions with screenshots for your specific phone model.
Pros:
- Cheapest option by a wide margin
- Flexible plan sizes for any trip length
- Excellent app with real-time data tracking
- Wide plan selection
- Works in 200+ countries (useful if China is one stop on a larger trip)
Cons:
- Data caps require usage awareness
- Not all plans bypass the GFW — choose China-specific plans carefully
- Slower than Holafly in our tests
- No built-in VPN layer
- No local phone number
Best for: Budget travelers, short trips (under a week), and light data users who mainly need maps and messaging.
#3 Nomad — Best for Multi-Country Trips
Network: China Unicom Data: Fixed plans (1GB to 10GB) Speed: 10-25 Mbps typical download
Nomad’s biggest advantage isn’t its China performance specifically — it’s the regional plans that cover China, Hong Kong, and Macau on a single eSIM. If your itinerary includes a stop in Hong Kong (and many China trips do), Nomad saves you from juggling multiple eSIM profiles.
On pure China performance, Nomad lands third. It runs on China Unicom, which has good urban coverage but noticeably weaker signal than China Mobile in suburban areas and on trains. We averaged 18 Mbps in Shanghai and 15 Mbps in Beijing, with some dead spots on the Chengdu metro’s newer lines.
GFW bypass worked most of the time, but we had a few instances where Google took unusually long to load — suggesting the routing isn’t as consistently foreign-server-based as Holafly or Airalo’s dedicated China plans. It resolved each time by toggling airplane mode, but it’s worth noting.
Pricing:
| Plan | Duration | Price | Per Day |
|---|---|---|---|
| 1GB | 7 days | $5.00 | $0.71 |
| 3GB | 15 days | $11.00 | $0.73 |
| 5GB | 30 days | $18.00 | $0.60 |
Setup: App-based, similar to Airalo. Clean interface, straightforward installation. Regional plan selection is easy to find.
Pros:
- Regional plans covering China + Hong Kong + Macau on one eSIM
- Competitive pricing
- Decent app experience
- Good option if you already use Nomad for other destinations
Cons:
- Lower speeds than Holafly and Airalo
- China Unicom coverage weaker outside major city centers
- GFW bypass less reliable — occasional hiccups
- Smaller plan selection for China specifically
Best for: Travelers visiting China plus Hong Kong or Macau on the same trip who want one eSIM for the whole journey.
Honorable Mentions
Trip.com eSIM — If you’re already booking flights or hotels through Trip.com, their eSIM add-on is convenient. It runs on China Mobile, prices are reasonable, and you can bundle it with your booking. The downside is limited plan flexibility and no standalone app for managing your connection.
Local SIM card — Still the cheapest option if you don’t mind the hassle. Walk into a China Mobile, China Unicom, or China Telecom store with your passport, and you can get a prepaid SIM for as little as 50-100 RMB ($7-14) with several GB of data. The catch: registration takes 30-60 minutes, staff rarely speak English, and a local SIM does NOT bypass the Great Firewall — you’ll need a VPN for everything. Only worth it if you need a Chinese phone number for local services.
Comparison Table
| Provider | Network | Data | GFW Bypass | Avg. Speed | Price (10-day est.) | Hotspot | Best For |
|---|---|---|---|---|---|---|---|
| Holafly | China Mobile | Unlimited | Yes (built-in VPN) | 30-50 Mbps | ~$34 | 500MB/day | Most travelers |
| Airalo | China Mobile/Unicom | 1-20GB plans | Yes (China plans) | 15-35 Mbps | ~$9-18 | Varies by plan | Budget travelers |
| Nomad | China Unicom | 1-10GB plans | Mostly | 10-25 Mbps | ~$8-14 | Varies by plan | Multi-country trips |
| Trip.com | China Mobile | Fixed plans | Yes | 15-30 Mbps | ~$12-20 | Limited | Trip.com users |
| Local SIM | Any carrier | Varies | No | 20-80 Mbps | ~$7-14 | Yes | Long stays, local number needed |
eSIM vs. VPN: Which Do You Need?
Short answer: both.
Here’s how it breaks down:
eSIM alone gets you unrestricted internet on your phone’s mobile data. Walking around the city, riding the metro, sitting in a park — your eSIM data bypasses the Great Firewall. Google Maps works. WhatsApp works. You’re good.
The problem starts when you connect to WiFi. Hotel WiFi, airport WiFi, cafe WiFi, coworking space WiFi — all of these go through Chinese networks. Your eSIM bypass doesn’t apply. The Great Firewall is fully in effect. Google is blocked. WhatsApp is blocked. Everything you need is blocked.
That’s where a VPN comes in. A VPN encrypts your traffic and tunnels it out of China, regardless of whether you’re on WiFi or cellular. It works on your laptop too, which your eSIM doesn’t cover.
Our recommended setup for China 2026:
- eSIM (Holafly or Airalo) for seamless mobile data throughout the day
- VPN (installed and tested before you leave) for hotel WiFi, laptops, and as a backup
This combo means you’re never without access. If your VPN is having a slow day on hotel WiFi, switch to eSIM data. If you’ve burned through your Airalo data cap, connect to WiFi and fire up the VPN.

How to Set Up Your eSIM (Step by Step)
Setting up an eSIM for China takes about five minutes. Do it before you board your flight — you don’t want to be fumbling with QR codes at immigration.
Step 1: Check your phone compatibility. eSIM works on iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and most flagship Android phones from 2019 onward. Your phone also needs to be carrier-unlocked. If you bought it directly from Apple or Samsung, it’s unlocked. If you got it through a carrier on a payment plan, check with them first.
Step 2: Purchase your eSIM plan. Go to your chosen provider’s website or app — Holafly, Airalo, or Nomad. Select a China plan (or China + Hong Kong for Nomad). Pay with a credit card or PayPal. You’ll receive a QR code via email or in the app within minutes.
Step 3: Install the eSIM profile. On iPhone: Settings > Cellular > Add eSIM > scan the QR code. On Android: Settings > Network & Internet > SIMs > Add eSIM > scan the QR code. Label it something clear like “China Travel” so you can identify it later.
Step 4: Configure but don’t activate yet. After installation, you’ll see your new eSIM listed alongside your regular SIM. Keep your regular SIM as the primary for calls and texts. Set the new eSIM as your data line — but do not turn on data roaming yet.
Step 5: Activate after landing. Once you’re through immigration and in China, go to your cellular settings and enable data roaming on your travel eSIM. Give it 30-60 seconds to connect. Open Google in your browser — if it loads, you’re bypassing the firewall and you’re all set.
Step 6: Test key apps. Open WhatsApp, Google Maps, and one more blocked app (YouTube or Gmail). If everything loads, you’re good for your trip. If something doesn’t work, toggle airplane mode on and off, wait 15 seconds, and try again.
FAQ
Does eSIM work on all phones? No. You need a phone that supports eSIM — generally iPhone XS (2018) or newer, and most Android flagships from 2019 onward. Older phones and some budget Android models only support physical SIM cards. Your phone also needs to be carrier-unlocked. Check your provider’s compatibility tool before purchasing.
Can I keep my regular phone number? Yes. eSIM runs alongside your existing SIM (or primary eSIM). Your regular number stays active for calls and texts. You just use the travel eSIM for data. People can still call and text you on your home number — though be aware of international roaming charges on your home plan. Consider putting your home SIM in airplane mode and using WhatsApp calls instead.
Does eSIM work on high-speed trains and in the metro? Mostly. In our testing, China Mobile-based eSIMs (Holafly, some Airalo plans) held a connection for about 85% of the Beijing-Shanghai high-speed train route. China Unicom-based plans (Nomad) dropped to around 60%. Metro coverage in Beijing, Shanghai, and Chengdu was good on all providers, though you’ll hit brief dead spots between some stations on older lines.
What happens if I run out of data on my Airalo or Nomad plan? You can top up directly in the app. Airalo makes this especially easy — you can purchase an additional plan and it activates immediately. Alternatively, connect to WiFi and use your VPN. This is another reason we recommend having both an eSIM and a VPN as backup for each other.
Can I use eSIM data to set up Alipay or WeChat Pay? Setting up Alipay and WeChat Pay requires an internet connection, which your eSIM provides. However, full functionality on these apps requires linking a payment method (international credit card or bank account) and sometimes phone verification. The eSIM doesn’t give you a Chinese phone number, which can be a limitation for some verification steps. Check our Alipay setup guide for foreigners for the current workaround.
Do I still need a VPN if I have an eSIM? Yes, for WiFi connections. Your eSIM only bypasses the Great Firewall on cellular data. Any time you’re on WiFi — hotel, cafe, airport — you need a VPN to access blocked sites and apps. If you have Holafly with its built-in VPN on cellular, you’re covered on mobile. But for your laptop or any WiFi connection, you still need a standalone VPN. See our VPN recommendations.
Can I share my eSIM data with my laptop or travel partner? Tethering (hotspot) support varies by provider. Holafly includes 500MB/day of hotspot data. Airalo and Nomad support varies by plan — check the specific plan details before purchasing. Keep in mind that tethered devices will also benefit from the GFW bypass, making this a useful workaround for getting your laptop online without WiFi.
The Bottom Line
For most travelers to China in 2026, here’s what we recommend:
Go with Holafly if you want the easiest, most reliable experience. Unlimited data, built-in VPN, fastest speeds, China Mobile’s network. You pay more, but you never think about data usage or firewall issues on your phone. For a one- to two-week trip, the $34-48 is well worth the peace of mind.
Go with Airalo if you’re on a budget or taking a short trip. A 5GB plan for $16 will cover a week of maps, messaging, and light browsing. Just make sure you pick a China-specific plan for reliable GFW bypass, and keep an eye on your data usage in the app.
Go with Nomad if your trip includes Hong Kong or Macau alongside mainland China. One eSIM, one plan, no swapping profiles at the border.
Regardless of which eSIM you choose, install a VPN before you leave home. You will need it for WiFi connections — and hotel WiFi is often faster than cellular for large downloads and video calls. Our best VPN for China guide is updated monthly with current recommendations.
