SIM Cards, eSIMs & Internet
Getting online in China in 2026: eSIM vs local SIM, passport registration, roaming, blocked apps, hotel Wi-Fi and how to stay connected without surprises.

China’s mobile networks are fast and cheap, but the internet is not the same internet you use at home: Google, WhatsApp, Instagram and many Western apps are blocked on local connections. The practical choice is between a local SIM (cheap data, Chinese number, blocked apps) and an international eSIM or roaming plan (more expensive, keeps your usual apps). This guide explains the trade-off and how to activate either before you land.
Key points
The details that matter
Local SIM vs international eSIM
A local SIM from China Mobile, China Unicom or China Telecom is the cheapest way to get large amounts of data. You need your passport, and the SIM must be registered in your name. It gives you a Chinese phone number, which helps with hotel Wi-Fi portals, some delivery apps and local calls, but it routes through the mainland internet, so Google, WhatsApp, Instagram and many foreign services are blocked. An international eSIM from providers such as Airalo, Nomad or Holafly, or simply enabling your home carrier’s roaming, keeps your usual apps working because traffic is routed abroad. It costs more, and a data-only plan has no Chinese number.
- Local SIM: cheap data, Chinese number, blocked foreign apps, passport required
- International eSIM: keeps Google/WhatsApp working, no Chinese number, higher cost
- Home roaming: simplest, often expensive, same access as eSIM
- Dual-SIM phone: keep your home SIM for messages and add a data eSIM
Buying and activating
Buy an eSIM before you fly and install it at home, where you have reliable internet and can test it. For a local SIM, airport desks are convenient but may have long queues and sell only tourist packages; city carrier shops are cheaper but often Chinese-only. Bring your passport. Registration is mandatory and usually takes a few minutes. Ask the staff to activate data and show you the APN settings if the connection does not work. Keep the physical SIM ejector tool in your bag.
What is blocked, and what that means
Google services (Search, Maps, Gmail, Drive), WhatsApp, Instagram, Facebook, X and many Western news sites are blocked on mainland connections. Some services work intermittently. If you rely on Google Maps for navigation, download an offline map or use Amap (available in English) instead. If you need WhatsApp for family or work, plan for roaming or an international eSIM. VPN use is restricted and can be unreliable; do not assume you can install one after arrival, and do not rely on it for emergencies.
Wi-Fi and staying reachable
Hotels, cafes and airports offer Wi-Fi, but portals may ask for a Chinese phone number, room number or WeChat login. Save screenshots of your hotel address and key contacts. For calls home, WhatsApp or FaceTime need an unblocked connection; international roaming or an eSIM is the reliable route. Chinese numbers are useful for restaurant queues and some mini-programs, but most visitors manage without one. If you need a number, a local SIM is the cheapest way to get it.
What works in practice
Install and test your eSIM before departure
Download offline maps and translation packs before you fly
Bring a power bank — navigation and translation drain battery
Keep your home SIM active for bank verification codes
Ask the hotel for the Wi-Fi password and whether the portal needs a Chinese number
Save your hotel address in Chinese offline
Mistakes to avoid
Arriving with only a data eSIM and discovering a service needs a Chinese number
Assuming Google Maps will work on a local SIM
Buying a SIM at the airport without comparing the data allowance
Forgetting that hotel Wi-Fi portals may need a Chinese number
Depending on a VPN for essential communication
Frequently asked
Can I use Google Maps in China?
Not reliably on a local connection. Use Amap (Gaode) or Baidu Maps, or keep an international eSIM/roaming connection if you need Google services.
Do I need a Chinese phone number?
Most visitors do not. It helps with some mini-programs, hotel Wi-Fi portals and local calls. A data-only eSIM is enough for maps, messaging and payments.
Can I buy a SIM at the airport?
Yes, with your passport, but airport plans are often tourist-priced and queues can be long. City carrier shops or an eSIM bought in advance are usually better value.
Is a VPN necessary?
If you need blocked services, the more reliable route is international roaming or an eSIM that routes traffic abroad. VPN use is restricted, can be unreliable, and should not be your only plan.
