Getting Online in China (2026): eSIMs, VPNs and What Actually Works

Published August 6, 2026 · by the GuoTalk team

Why your phone behaves differently in China

China's network filtering applies to traffic that exits to the wider internet inside mainland China. That single sentence explains almost everything else on this page.

If your data leaves the country before it reaches the open internet — which is what happens on a roaming connection — it isn't subject to that filtering. If your data exits locally, it is. So the question isn't really "which SIM is best." It's "where does my traffic break out?"

Option 1: a travel eSIM (what most visitors should do)

A travel eSIM you buy before you leave installs as a second line on your phone and roams onto a Chinese carrier. Because the data is routed out of the country, blocked services generally load without a VPN.

Practical notes:

• Where it breaks out matters for speed. Plans that exit via Hong Kong, Singapore or Thailand tend to feel faster than ones routed to Europe or the US.
• Install and activate before you fly — or at least download the QR code and instructions. Activating an eSIM usually needs working internet, which is exactly what you won't have at arrivals.
• Check your phone is eSIM-capable and carrier-unlocked. This catches people out more than it should.
• Tethering from a roaming line usually passes the same routing to your laptop, but some carriers throttle or block hotspot use abroad. Test it at home.

We're deliberately not publishing a ranked list of eSIM brands. Almost every "best eSIM for China" article you'll find is written by an eSIM seller or paid by one, and the few genuine hands-on tests we could find are close to two years old. Buy from a provider with a refund policy, and buy a small plan first.

One thing a working eSIM still might not fix

Because many China travel eSIMs break out in Hong Kong, and because OpenAI does not serve mainland China, Hong Kong or Macau, ChatGPT can still fail on an eSIM that unblocks everything else. That's a restriction on OpenAI's side, not China's. A VPN exiting in Japan, Singapore or the US is the workaround.

Option 2: roaming from your home carrier

Roaming often works for the same reason: many carriers tunnel your data back to the home network before it reaches the internet. But this is carrier-dependent — some route data locally instead, which puts you back inside the filtered path.

There's no reliable public list of which carriers do which. Call your carrier and ask specifically whether data roaming in China is home-routed. Then check the price, because daily roaming rates in China are frequently brutal.

Option 3: a local Chinese SIM (for the +86 number, not for the internet)

You may still want one. A mainland number unlocks things a foreign number can't always do: delivery app registrations, some ticketing, contact fields that reject international formats.

• What you need: your original passport, valid at least six months, and a valid Chinese visa or residence permit. Some big-city branches also ask for a hotel booking or proof of address.
• Real-name registration is mandatory, in person, and includes a facial-recognition scan. This has been the rule since December 2019.
• Limit: a passport holder may hold a maximum of five SIM cards.
• Where: airport arrivals counters (usually open roughly 07:00–24:00), official China Mobile / Unicom / Telecom stores, and some convenience stores that support foreigner registration. Not every branch will serve foreign nationals — call ahead or use the airport.

China approved commercial eSIM service for smartphones from its three major carriers in October 2025, so local eSIMs now exist. That's a hardware convenience, not a routing change — a local eSIM still breaks out inside the mainland. Whether short-stay visitors can obtain one, and on what terms, isn't clearly documented.

VPNs in 2026: install early, expect turbulence

This is the part of the advice that has genuinely changed in the last year, and older articles will steer you wrong.

Following a crackdown reported around April 2026, VPN reliability degraded noticeably — network providers were reportedly asked to block VPN services, and at least one consumer VPN suspended its service outright citing continuous blocking. Users report it's harder than it used to be to find something stable.

What to actually do:

1. Install two or three different VPNs before you leave. Pick ones with 30-day money-back guarantees, try them on arrival, keep whichever works, refund the rest.
2. Don't rely on the VPN as your primary plan. A roaming eSIM has no app to be blocked and no server to be throttled. Treat the VPN as the backup for things the eSIM doesn't cover.
3. Log in and configure everything at home — including any account creation, because the VPN's own website may be unreachable from inside.

We're not publishing a "best VPNs for China" ranking. Any list is stale within weeks and every list we found was affiliate-monetised.

What works and what doesn't

As a rough map of what you'll hit on an unrouted mainland connection:

Generally reachable: Bing (with filtered results), iMessage and FaceTime, and most Western banking sites. Netflix and similar will load but geo-restrict you themselves.

This list drifts. Treat it as the shape of the problem, not a guarantee.

Install the Chinese alternatives before you go

Even with a working eSIM, the local apps are simply better inside China. Amap (高德地图) and Baidu Maps have English interfaces and know about things Google Maps doesn't — metro exits, real bus times, which building entrance the restaurant is actually behind. Download at least one before you fly.

You'll also want Alipay and WeChat set up in advance — see our guide to paying in China as a tourist. Both work fine on Chinese networks with no VPN.

Hong Kong and Macau

Mainland filtering doesn't apply in Hong Kong. Google, Instagram, WhatsApp and YouTube all work normally on a local connection.

Two things to know:

• Hong Kong has its own real-name SIM registration. Non-residents can register with a passport or other valid travel document, and it's free — but it isn't a walk-in-and-go purchase.
• Coverage is sold separately. A mainland-only plan generally won't include Hong Kong or Macau; providers sell combined "China + Hong Kong + Macau" products for a reason. Check the coverage list before you buy, not after.

The five mistakes worth avoiding

1. Arriving without the VPN installed. You often can't download one once you're there.
2. Buying a local SIM expecting it to unblock things. It won't. Different tool, different job.
3. Connecting to hotel Wi-Fi and thinking your eSIM broke. The routing advantage applies only to your eSIM's own mobile data. Turn Wi-Fi off and try again.
4. Making a VPN your only plan in 2026. After April, that's a bet you may lose.
5. Assuming everything unblocks equally. ChatGPT in particular can fail even when everything else works.

A five-minute pre-flight checklist

1. Buy and install a travel eSIM; confirm it activates.
2. Install two VPNs and sign into both.
3. Install Alipay and WeChat, link a card, complete passport verification.
4. Install Amap or Baidu Maps.
5. Screenshot your hotel address in Chinese characters. You'll need it more than you expect.
6. Decide whether you want a +86 number, and if so, plan to buy the SIM at the airport on arrival.
