Getting online in China: eSIM vs VPN
China's firewall blocks Google, WhatsApp, Instagram and much of the Western web. A roaming eSIM is the no-fuss way around it; a VPN still works too, with more fiddling since 2026. Either way, set it up before you land.

Short answer
Two things get you to Google, WhatsApp and Instagram. The no-fuss one is a roaming-based travel eSIM (Holafly, Airalo, Nomad and similar): because it routes your data through a carrier outside mainland China, blocked sites just work, with no VPN. The other is a VPN — hit hard by an April 2026 crackdown, but the better travel VPNs adapted and a well-chosen one works again for most people, just less reliably than before. Install whichever you use before you fly. A local Chinese SIM is cheap but does not get past the firewall on its own; home-carrier roaming usually does, at a price.
What’s blocked
Google (Search, Maps, Gmail, Play Store), WhatsApp, Instagram, Facebook, X/Twitter, YouTube, many Western news sites, and more. Some services flip on and off; assume anything Google- or Meta-owned is unreachable on a plain local connection.
The reliable route: a roaming travel eSIM
Buy it online at home, install the eSIM profile, and switch it on when you land. Providers such as Holafly, Airalo and Nomad sell “China” plans that route your data through a carrier outside mainland China — usually Hong Kong or Singapore — so your traffic enters China through the international gateway. The practical effect: Google, WhatsApp and Instagram work with no VPN.
The catch is in the wording. A roaming eSIM does this; a local Chinese eSIM does not. Check the plan says it uses partner/roaming networks, or that it explicitly “works with Google/WhatsApp”.
Install it before you fly — you generally can’t download the profile once you’re inside the firewall.
Using a VPN
For years the standard advice was “install a VPN before you go”, and it still has a place — it covers all your devices, keeps your normal logins, and can be cheaper than an eSIM on a long trip.
It took a hit in April 2026, when a crackdown (nicknamed the “Great Unplug”) cut thousands of the relay servers consumer VPNs rely on. For a few weeks most stopped working. The better travel VPNs have since adapted — the ones using advanced traffic obfuscation, which makes the connection look like ordinary web traffic — and a well-chosen one works again for most travellers, if less reliably than before: expect the odd reconnect, slower speeds, and tighter squeezes around politically sensitive dates.
Two rules still hold: install and test it before you fly (VPN sites and app-store listings are blocked inside China), and don’t make it your only plan — pair it with, or fall back to, a roaming eSIM.
Local Chinese SIM
China Unicom and China Mobile run counters in the international arrivals area of every major airport — buy a short-stay tourist SIM there with your passport before you leave the terminal. It’s cheap, and it gives you two things a foreign eSIM doesn’t: a Chinese +86 number (which some apps and booking flows want) and local calling.
What it does not do is get you past the firewall — blocked sites stay blocked on it. Use it alongside a roaming eSIM or a VPN, as your number and data top-up, not your way over the wall.
Home-carrier roaming
Turning on data roaming with your own carrier usually reaches blocked sites, because your traffic is routed back through your home network. It just works, but the daily or per-MB cost can be steep — worth it for a short trip, worth checking first.
Practical tips
- Download offline maps for your cities before you go.
- Bing and Apple Maps work in China; Google Maps doesn’t.
- Reach email through its app, not a browser, if the web version is blocked.
- WeChat always works locally — a useful fallback for staying in touch.

Scope
What this guide does not cover
- A cast-iron guarantee that a given VPN connects on a given day — the firewall pushes back, especially around sensitive dates.
- Corporate or managed-device network setups.
- Reliably streaming your home Netflix, BBC iPlayer and similar.
FAQ
Common questions
Will my normal phone just work?
Calls and texts roam normally. Data roaming from your home carrier usually reaches blocked sites, but can be costly — check your plan. Data on a local Chinese SIM or a non-roaming eSIM hits the firewall.
Do I still need a VPN if I have a travel eSIM?
Not for getting past the firewall — a roaming eSIM already routes you outside it. A VPN is still worth having if you want all your devices covered, your usual logins, or a cheaper option on a longer trip.
Is using a VPN legal for tourists?
It's a long-standing grey area. There are no known cases of tourists being penalised for using a mainstream VPN on a personal phone. Practically, the question is which one still connects well — see the guide.
Can I sort this out after I land?
No. eSIM profiles, VPN apps and their websites are all blocked or unavailable from inside China. Buy and install before you board.
