The internet situation in China confuses everyone. Let me simplify it for you.
The short version:
- You need BOTH an eSIM/SIM (for data) AND a VPN (for accessing blocked sites)
- An eSIM gives you data but NOT a Chinese phone number
- A VPN gives you access to Google/Instagram/WhatsApp but needs data to work
- A Chinese SIM gives you a phone number (useful for app registration) + data
They serve different purposes. Here's exactly what each one does and doesn't do.
Quick Comparison
| eSIM | Chinese SIM | VPN | |
|---|---|---|---|
| Data | β Yes | β Yes | β No (needs WiFi/data) |
| Chinese phone number | β No | β Yes | β No |
| Access Google/Gmail/Instagram | β Yes* | β No | β Yes |
| Works immediately on landing | β Yes | β Need to buy at store | β οΈ Needs data first |
| Price (1 week) | $5-20 | Β₯50-100 ($7-14) | $5-15 |
| Setup difficulty | Easy | Medium (passport needed) | Easy (must do before trip) |
*eSIM data often routes through Hong Kong, which bypasses the Great Firewall
Option 1: eSIM β The "Land and Work" Solution
Best for: Anyone who wants internet the moment the plane lands.
How it works:
- Buy an eSIM plan before your trip (on Airalo, Holafly, Nomad, etc.)
- Scan a QR code to install
- Activate it when you land
- You have data immediately β before you even get off the plane
Pros:
- Instant connectivity
- No need to find a phone shop
- No passport registration
- Can keep your home SIM active simultaneously (dual SIM)
- Many eSIMs route through Hong Kong β you can access Google/Instagram/WhatsApp WITHOUT a VPN!
Cons:
- Data only β no Chinese phone number
- Cannot register for some Chinese apps (Meituan, some bike sharing) without a local number
- More expensive per GB than local SIM
- Requires eSIM-compatible phone (iPhone XS or newer, most recent Androids)
Recommended eSIM providers for China:
| Provider | 7 Days | 30 Days | Bypasses Firewall? |
|---|---|---|---|
| Airalo (China Unicom) | $8 (3GB) | $25 (10GB) | Sometimes |
| Holafly | $19 (unlimited) | $44 (unlimited) | β Yes |
| Nomad | $7 (3GB) | $19 (10GB) | Sometimes |
| 3HK (Hong Kong) | $12 (5GB) | $38 (30GB) | β Yes |
Pro tip: Holafly and 3HK route through Hong Kong, which means no VPN needed for accessing Google, Instagram, WhatsApp, etc. This alone makes them worth the slight premium.
Option 2: Chinese Local SIM β The "Full Integration" Solution
Best for: Staying more than 2 weeks, or needing local app registration.
How to get one:
- Find a China Mobile, China Unicom, or China Telecom store
- Bring your PASSPORT (original, not a copy)
- Choose a plan (they'll show you options β data is cheap)
- They'll register your passport, take a photo, and activate your SIM
- Total time: 15-30 minutes
Pros:
- Chinese phone number (register for apps, receive SMS verification codes)
- Cheap data (Β₯50-100/month for 20-50GB)
- Fast speeds (better than roaming/eSIM in some areas)
- Can receive calls from Didi drivers, hotels, etc.
Cons:
- Need to physically go to a store (English service not guaranteed outside big cities)
- Passport registration required
- Chinese SIM = Chinese internet = NO Google, Instagram, WhatsApp without VPN
- Minimum contract sometimes required (though prepaid exists)
What to say at the store (show on your phone if you don't speak Chinese):

"I want to get a SIM card, for travel, one month"
Option 3: VPN β The "Freedom" Solution
Best for: Accessing blocked sites and apps. Period.
What a VPN does: Creates an encrypted tunnel to a server outside China, so websites think you're in another country.
Critical rule: INSTALL AND TEST BEFORE YOU FLY.
Chinese internet blocks access to VPN provider websites. If you wait until you're in China to download a VPN, you're already too late.
VPNs that actually work in China (tested 2025):
| VPN | Reliability | Speed | Price | Notes |
|---|---|---|---|---|
| Astrill | βββββ | ββββ | $20-30/mo | The gold standard. Most reliable. |
| LetsVPN | ββββ | ββββ | $5-8/mo | Cheaper, surprisingly good. |
| ExpressVPN | βββ | ββββ | $13/mo | Hit or miss lately. |
| NordVPN | ββ | βββ | $12/mo | Often blocked. Not recommended. |
| Mullvad | β | β | β¬5/mo | Basically doesn't work. Skip. |
Setup checklist before departure:
β‘ Choose and pay for VPN (at least 1 month)
β‘ Install on phone AND laptop
β‘ Test: connect to VPN β open Google β does it work?
β‘ Save VPN provider's alternate connection methods (they often provide backup servers)
β‘ Write down your VPN login info somewhere offlineThe Winning Combination
Here's what I recommend for most travelers:
Week 1-2 trips β eSIM only (Holafly/3HK for firewall bypass)
No VPN needed with HK-routed eSIM!
2-4 week trips β eSIM (land with data) + Chinese SIM (get on Day 2)
+ VPN (install before trip, use with Chinese SIM)
Digital nomads β Chinese SIM (cheap, local number)
+ VPN (mandatory)
+ eSIM as backup (for days when VPN acts up)Why This Order Matters
DAY 1: Land with eSIM β instant internet β book DiDi β message hotel
(You're functional within 5 minutes of landing)
DAY 2: Go to China Mobile/Unicom β get local SIM β cheaper data β
local number for apps
ONGOING: Use VPN when on local SIM / hotel WiFi
Fall back to eSIM if VPN stops workingWhat About Pocket WiFi?
Pocket WiFi is the old-school option: a portable device that creates a WiFi hotspot.
Verdict: Skip it unless you're traveling in a group.
- Another device to carry and charge
- ~$5-10/day β more expensive than eSIM or local SIM
- Same internet restrictions as Chinese SIM (needs VPN for blocked sites)
- The only advantage: multiple people can share it
The Bottom Line
If you do nothing else before your trip, do these two things:
- Buy an eSIM (Holafly or 3HK) β $10-20 for your first week of data, and it will likely bypass the firewall
- Install and test a VPN (Astrill or LetsVPN) β $5-20, your backup for when eSIM routes through mainland China
That's it. That's what 99% of travelers need.
