Staying Connected in Shanghai: What You Need to Know

Visiting China means dealing with the Great Firewall—the world’s most sophisticated internet censorship system. Google, WhatsApp, Instagram, and most Western apps don’t work without preparation. This guide covers everything you need to stay connected.

The Great Firewall: What’s Blocked?

Before diving into solutions, understand what doesn’t work in China:

Completely Blocked (Need VPN)

CategoryBlocked Services
GoogleSearch, Gmail, Maps, Drive, Photos, YouTube
Social MediaFacebook, Instagram, Twitter/X, WhatsApp, Telegram, Discord
StreamingNetflix (partial), Spotify
OthersReddit, Dropbox, many news sites

Works Without VPN

Apple ServicesiCloud, Maps, App StoreMostly works
MicrosoftOutlook, Teams, OneDriveWorks
ZoomVideo callsWorks

⚠️ Critical: WeChat and Alipay are NOT blocked—they’re China’s dominant apps. Download them before you go!


eSIMs are the easiest solution—no physical SIM swap, instant activation, and many include VPN for unblocked access.

How eSIM Works

  1. Purchase online before your trip
  2. Scan QR code to install
  3. Activate when you land
  4. Keep your home SIM active for calls/texts

eSIM Pros

  • No SIM card swap needed
  • Instant activation
  • Keep home number active
  • Many include VPN access
  • Buy from anywhere before travel

eSIM Cons

  • Requires eSIM-compatible phone (iPhone XS+, newer Android)
  • Not all plans include VPN (check before buying!)
  • May have slower speeds than local SIM
  • Can’t make local Chinese calls

💡 Pro Tip: Always choose an eSIM plan that explicitly includes VPN access. Without it, you’ll still be blocked from Google and social media.

Is Your Phone eSIM Compatible?

iPhone: XS, XR, and all newer models Android: Google Pixel 3+, Samsung Galaxy S20+, many newer models Not Sure? Go to Settings → Cellular/Mobile → look for “Add eSIM” option


Option 2: Physical SIM Card

For longer stays or if you need a local Chinese number, a physical SIM is the way to go.

Option 3: Pocket WiFi

Good for groups traveling together who want to share one connection.

How It Works

  1. Pre-order online or book at airport
  2. Pick up device at airport
  3. Connect all your devices
  4. Return at end of trip

Typical Costs

  • Daily rental: $5-10/day
  • Deposit: $50-100 (refundable)

The free option—but with significant limitations.

  • Cafes and restaurants (Starbucks, etc.)
  • Shopping malls
  • Metro stations (patchy)
  • Airports

Free WiFi Pros

  • Free
  • Available in most tourist areas
  • Works for basic needs

Free WiFi Cons

  • Often slow and unreliable
  • Security concerns on public networks
  • No connectivity while moving
  • Quality varies wildly

💡 Tip: Hotel WiFi is fine for WeChat and Chinese apps. But if you need Google Maps or Instagram, you still need a VPN.


VPN: The Essential Add-On

Unless your eSIM/SIM includes VPN, you’ll need one to access blocked services.

Critical VPN Rules

  1. Download BEFORE arriving in China - VPN websites are blocked
  2. Install 2-3 different VPNs - One may stop working
  3. Free VPNs rarely work in China
  4. Test before you go - Make sure it connects

VPNs That Work in China (2026 Tested)

VPNReliabilityPriceNotes
ExpressVPNHigh$13/monthBest overall
NordVPNGood$12/monthGood value
AstrillHigh$15/monthExpensive but reliable
SurfsharkGood$10/monthBudget option

VPN Reality Check

In real-world testing, only 7 out of 28 VPNs consistently worked in China. The Great Firewall actively blocks VPN connections, so even good VPNs fail sometimes. Having multiple options is essential.

VPN Tips

  • Connect to Hong Kong or Japan servers for best speeds
  • If one server fails, try another
  • Turn off VPN for Chinese apps (WeChat, Alipay work better without)
  • Some hotels block VPN traffic—try mobile data instead

Frequently Asked Questions

Do I really need a VPN in China?

If you want to use Google, check Gmail, post on Instagram, or use WhatsApp—yes, absolutely. If you’re fine using only Chinese apps (WeChat, Alipay, Baidu Maps), you can survive without one.

VPNs exist in a gray area. Millions of people use them, including businesses. Tourists are extremely unlikely to face any issues. Just don’t use VPN for anything illegal.

Will my regular phone plan work?

International roaming works, but it’s expensive ($10-20/day) and doesn’t bypass the Great Firewall. You’ll still need a VPN for Google and social media.

Can I buy a VPN after arriving in China?

Very difficult—VPN websites are blocked. Some people use the App Store (which works), but many VPN apps have been removed from the Chinese App Store. Always install before traveling.

What if I forget to prepare anything?

  • Ask your hotel for help—they may have solutions
  • Try airport shops for tourist SIMs
  • Use WeChat to communicate (it works!)
  • Download Baidu Maps for navigation
