Surviving the Firewall
Everything you need to know about eSIMs, SIM cards, and staying online in China.
The Problem
China blocks Google, Meta (Facebook/Instagram/WhatsApp), and most Western services. Your choice of connection determines whether you get unrestricted access or need a separate VPN.
Local SIM
Restricted internet. Fast local speeds. Requires a VPN app for Google/IG.
Roaming eSIM
Unrestricted. Routes via Hong Kong/Singapore (DRACIX routes via London). No VPN needed.
Global Popularity of Connection Types
Traveler preference shift (2023-2024)
Pick Your Option
International Roaming eSIM
Best for Most- Bypasses Firewall (No VPN needed)
- Instant setup via QR code
- No local Chinese phone number
Providers: Airalo, Nomad, Holafly
Local Physical SIM
Long Term / Business- Get a +86 Number (Vital for some apps)
- Very cheap data rates locally
- Requires passport registration at store
- Needs VPN for Western apps
Providers: China Mobile, China Unicom
Carrier Roaming
Convenience / Pricey- Keep your home number active
- Usually bypasses Firewall
- Expensive ($10/day caps often)
Providers: Verizon, AT&T, Vodafone
What It Costs
Data is cheap in China, but convenience costs more. Local SIMs are the cheapest per GB but require in-person setup. eSIMs balance cost and instant activation.
Pro Tip
Avoid "Pay-As-You-Go" roaming from your home carrier unless you have a specific travel pass. It can cost upwards of $2,000/GB without a plan.
Price Comparison: 10GB Data Package (15 Days)
*Prices are approximate averages as of late 2024. "Home Carrier" assumes a $10/day pass.
How Much Data Do You Need?
The "Super App" Economy
In China, WeChat (Weixin) and Alipay are operating systems for life. You will use them for payments, ordering food, booking taxis, and messaging. While they don't consume huge data for payments, the integrated "Mini Programs" (videos, maps, shopping) add up.
Your Connection Checklist
1 Week Before
Download WeChat & Alipay. Link your foreign credit card (Visa/Mastercard) to Alipay. Complete the "Real Name Verification" by uploading your passport photo in the app.
3 Days Before
Buy your eSIM. Scan the QR code to "install" it, but do not activate roaming yet. If getting a local SIM, ensure your phone is unlocked.
On Arrival
Landing in PVG/PEK: Switch eSIM line to "On". Turn on "Data Roaming" for that line. It should connect to China Mobile or China Unicom instantly.
