Staying Connected

The eSIM advantage

China's mobile networks (China Mobile, China Unicom, China Telecom) are excellent, and the easiest way to use them is an eSIM bought online before you fly. Install the QR code at home, and the moment you land you have data — no shop, no passport registration, no SIM tray.

Airalo, Nomad, Holafly and similar services sell China eSIMs from about USD 5-10 for a week of data.

• Buy from a roaming eSIM provider and scan the QR code while still abroad
• Data-only eSIMs are fine for maps, translation and payments
• Check your home phone: eSIM requires iPhone XS+/most 2020+ Androids
• Keep your home SIM active for OTP codes via roaming or Wi-Fi calling

Physical SIM cards

If your phone has no eSIM, physical SIMs are sold at airport counters (China Mobile/Unicom/Telcom) and require your passport for registration. Tourist plans with 7/15/30-day data are available from about RMB 100-300.

At airport counters, ask for the 'tourist card' — staff speak enough English to help. Registration takes 5-10 minutes.

Free Wi-Fi realities

Hotels, most cafés and many airports offer free Wi-Fi, but login often needs a Chinese phone number for SMS verification — the classic catch-22. Airport Wi-Fi can use passport scanning instead. Treat Wi-Fi as a bonus, not a plan: a local data connection is your primary lifeline.

What's blocked and why

Google (Search, Maps, Gmail), Instagram, Facebook, WhatsApp and many western services are blocked or unreliable inside China. WeChat, Alipay, Baidu Maps and local services work perfectly. The block is applied at the network level — your apps still exist, they just can't reach home.

This is a network policy, not a targeting of individuals; millions of locals use VPNs too.

Which VPN to use

Install and test your VPN before arriving — many providers don't offer China servers and some free VPNs simply don't work there. Paid services with strong obfuscation (e.g. Astrill, Let'sVPN, Mullvad, or any provider advertising China compatibility) generally work.

Set your VPN to auto-connect on Wi-Fi so you're never caught offline. If a connection fails, switch protocol (WireGuard → OpenVPN) or server city.

• Download and pay for the VPN while abroad (stores can block them inside China)
• Test every protocol before you fly
• Keep a second VPN as backup — reliability varies day to day
• Hotel Wi-Fi blocks VPNs more aggressively than mobile data; switch to 4G/5G if stuck

Google Maps alternative

Even with a VPN, Google Maps data in China is outdated. Download Amap or Baidu Maps with English UI — they power the best walking, metro and driving directions, show live train tickets, and integrate with ride-hailing.

Both apps work with foreign numbers (register with passport or just use as guest for navigation).

The translation stack

The winning combo: your usual translator (Google Translate works fine with VPN; DeepL is superb for longer texts) plus two China-native helpers — Youdao and Baidu Translate — which are never blocked and handle Chinese-to-English naturally.

All support camera translation: point your phone at a menu, sign or label and read the overlay instantly.

Offline packs

Download the Chinese language pack in Google Translate or Youdao before departure. Even with flawless mobile data, offline packs rescue you in tunnels, rural areas and when a VPN drops mid-conversation.

Plugs and voltage

China uses Type A/I plugs (two flat pins, sometimes three) at 220V. Most modern chargers are dual-voltage (100-240V) and need only a physical adapter — check the label on your charger brick. Bring one universal adapter; hotels often lend them too.

Battery life strategy

You'll use your phone constantly — maps, translation, payments, tickets. Carry a 10,000mAh power bank (under 100Wh, airline-safe), and know that metro stations and cafés rarely have public charging. A dead phone in China is a bigger problem than at home because it's your wallet, ticket and translator.

Protect your phone on the street

Street theft is rare but scooters and crowds are real hazards. Keep your phone in a zipped pocket or cross-body bag in busy markets, and avoid holding it out while walking near roads — the classic snatch-and-scooter trick happens in every country.
