Best eSIM for China: Stay Connected Beyond the Firewall (2026)

Planning a trip to China? Then you're probably already aware that getting online there is quite a challenge. Whether you're wandering the streets of Beijing or taking in the Shanghai skyline, you just want to use your phone the way you normally would. From my own travels across China, I've learned one thing: don't gamble on a VPN. They tend to let you down at the worst possible moment.

With a travel eSIM for China, you bypass the 'Great Firewall' effortlessly. Because your data is routed through international servers, blocked services like Google, Instagram and Facebook simply work, no fuss. In my experience it's the most reliable way to stay connected, and it saves you from high roaming charges too.

Short on time? My personal favorite is Jetpac. It gave me a reliable connection even in remote areas like Yunnan. Use code FYESIM15 for 15% off your Jetpac eSIM.

How to Choose the Right eSIM for China?

Which eSIM is best for you depends on your travel plans. But the questions you most likely have are: "Can I keep using my email and socials as usual in China?" and "Do I need a VPN?"

The short answer: with a travel eSIM (like those from Jetpac, Airalo or Eskimo), you do not need a separate VPN for your mobile data in China. This works differently from the physical SIM cards you buy at a Chinese airport. Because a travel eSIM uses international roaming, your data travels through a 'digital tunnel' straight to servers abroad. That bypasses local blocks entirely, so apps like WhatsApp, Instagram and Google work exactly as you'd expect. I've personally tested at least 15 different eSIMs in China and never had any trouble with these blocks. Only Google Maps was inaccurate, but that's for an entirely different reason.

If you've decided to get an eSIM, here are a few tips from my own experience:

• Check your usage: Most travelers use about 10 GB a month. One thing to keep in mind: hotel Wi-Fi in China is censored, so you may lean on your mobile data more than usual. But if you use 10 GB a month at home, don't jump straight to an expensive unlimited plan, you can always top up. Use our data calculator to estimate what you'll really need.
• The 'unlimited' myth: Every unlimited eSIM for China has a Fair Use Policy. If a provider isn't transparent about its daily limit (say, 3 GB a day), be cautious. Look for one that's clear about its terms.
• Hotspotting: If you want to share data with travel companions or your laptop, be aware that some (unlimited) eSIMs block this. Check the fine print before you order.

A quick heads-up: some eSIM providers route your traffic through servers in Hong Kong. While the internet is unrestricted there, companies like ChatGPT and TikTok often block access from that region themselves. In those cases, those specific apps might still not work. If you want an eSIM that avoids this entirely, look at Eskimo or Jetpac.

Test Results

Below are the results of my tests. Bear in mind these are snapshots in time: providers can change partners or routing methods, and results vary depending on the specific plan you buy. As you can see, all listed providers managed to bypass local internet restrictions.

These are snapshots from my own testing in China (chiefly in and around Shenzhen). The focus here is censorship, not raw speed: the Censorship column shows whether each eSIM bypassed the Great Firewall, and Routing shows which country your data appeared to exit from. All listed providers got past local restrictions. Providers can change partners and routing at any time, so treat this as a guide, not a guarantee.

The Hard Truth: Most VPNs Fail in China

Many blogs recommend a VPN as the ultimate fix for the 'Great Firewall', but in my experience most standard VPN services simply don't work reliably in China. While I'm a fan of services like NordVPN (I use it myself) and ExpressVPN, China is a different beast. The Chinese government actively blocks IP addresses linked to known VPN servers. Even the providers themselves often admit on their support pages that their standard apps struggle to stay connected there.

My test: 0 out of 4 worked "out of the box". I tested the most popular VPNs on their default settings in Shenzhen: ExpressVPN, NordVPN, Hotspot Shield and Surfshark. Not a single one worked immediately on arrival. I eventually got NordVPN to connect, but only after significant manual configuration and troubleshooting. For the average traveler that's far too complex and frustrating.

You'll often come across articles claiming VPNs work effortlessly. Be cautious: these are frequently outdated or written purely to earn commissions. If you want the truth, check the VPN providers' own help pages or browse Reddit for user reports from the past week. In China, what worked yesterday can be blocked today.

My advice: if you want a guaranteed connection without the technical headache, choose a travel eSIM. Because your data is routed through an international server (roaming), you skip the struggle with unreliable VPNs entirely.

Local networks in China

There are three major mobile operators in China:

• China Mobile
• China Unicom
• China Telecom

While locals often recommend China Mobile for its superior rural coverage, I've found that getting a local SIM from them as a tourist is a struggle thanks to strict ID verification and Chinese-language systems. That's why I prefer a travel eSIM. It automatically connects you to one or more of these networks, and in my experience your phone simply picks the strongest signal available. In cities, coverage is never an issue. If you're heading to remote provinces like Yunnan or Tibet, I'd check a tool like nPerf beforehand, but for most trips an eSIM handles network selection for you seamlessly.

Buying a local SIM card

Is your phone not eSIM-compatible, or are you too late to have a physical SIM delivered before your trip? Perhaps you're feeling adventurous and want to try a local Chinese SIM card. Most major airports offer plenty of options, but I'd stick to one of the three main providers. Ask a staff member to install the SIM for you, and make sure you're fully connected before you leave the shop, trying to work it out on your own later is not something I'd recommend.

That said, I don't recommend this route unless it's absolutely necessary. It can be time-consuming and confusing, and you'll still face the full restrictions of the Great Firewall once you're online. On my last visit to Shenzhen, I walked into an official China Unicom store to test the process myself. The SIM cost around $22. Thanks to a helpful member of staff I left with a fully working connection, though as expected many popular apps and websites were blocked. Surprisingly, WhatsApp did work on this local connection.

Not sure how to ask for a SIM card? Use a translation app, or simply show this message, which asks for a prepaid data SIM and help installing it:

Practical Tips Before Traveling to China

Heading to China soon? Based on my travels, here are some essential internet-related tips to help you prepare:

• Activate your eSIM before arrival: I recommend doing this ahead of time with providers like Jetpac. Once you're in China, some eSIM provider websites may be blocked by the Great Firewall.
• Set up WeChat before your trip: It's an essential app in China, you might even need it just to access airport Wi-Fi. Not ideal for privacy, but widely used and often necessary for daily life.
• Use WeChat or Alipay for payments: Cash is becoming rare and many places no longer accept physical Renminbi. International cards are often declined. Since 2023 you can link your international credit card to both WeChat and Alipay to pay like a local.
• Install a reliable maps app in advance: Apple Maps works well for iPhone users. On Android, avoid Google Maps as the location data is often inaccurate (due to a different GPS frequency used in China). Install an alternative like Maps.me instead.
• Install one or two backup browsers: Alongside Chrome, it's smart to have Firefox or Microsoft Edge on your phone or laptop. They tend to work more reliably in China.
• Using Gmail or Google Workspace? Set up email forwarding: Forward your messages to a Hotmail or Outlook address, or use a different mail app, to avoid losing access while you're in China.
• Be careful with VPNs: Don't buy an expensive VPN subscription unless you've seen very recent, clear instructions for using it inside China. Most VPNs don't work out of the box.

China is a fascinating and generally safe country that's well worth visiting. Don't let connectivity worries stop you: just be aware that internet access works differently there. A bit of preparation goes a long way.
