Detailed provider reviews for China

Airalo

Recommended

Airalo's China plan ('Chinacom') is one of the most important products in the company's catalogue because it bypasses the Great Firewall by routing traffic through Hong Kong. Google, Gmail, WhatsApp, Instagram, and YouTube all work normally — no VPN needed. The plan runs on China Unicom for cellular signal but routes data internationally. The 5 GB / 30-day plan is the minimum for a typical China trip given how much data Maps and Gmail burn when routed internationally.

Pros
  • Bypasses the Great Firewall — Google, WhatsApp, IG all work
  • Routes via Hong Kong, no VPN needed inside China
  • Runs on China Unicom — full national coverage
  • Skips local Chinese SIM registration paperwork
  • Hotspot enabled across all tiers
Cons
  • Significantly more expensive than non-China Airalo plans
  • Yesim has cheaper firewall-bypassing options
  • 1 GB plan is too small for any practical China trip
  • 5G availability varies depending on roaming partner

Yesim

Best price

Yesim's China plans also route traffic internationally, bypassing the Great Firewall the same way Airalo does. Pricing is significantly better — the 10 GB plan at $22 is meaningfully cheaper than Airalo's $22 / 10 GB equivalent and covers a typical China trip with room to spare. SwitchLess between China Mobile and Unicom is a real benefit because the strongest cellular operator varies by region. The unlimited plan suits business travellers doing video calls.

Pros
  • Bypasses the Great Firewall — same routing as Airalo
  • $22 / 10 GB matches Airalo's price for a 30-day plan
  • Network-hopping between Mobile and Unicom
  • Unlimited plan for video-call-heavy business trips
Cons
  • Still more expensive than non-China Yesim plans
  • iOS-only VPN feature
  • Unlimited plan price is high but justified for the use case
  • Less third-party verification of Firewall bypass than Airalo

Saily

Privacy-focused

Saily's China plan also routes internationally and bypasses the Great Firewall. Pricing is competitive at the entry tier ($3.49 / 1 GB) and the built-in ad blocker is more meaningful in China than elsewhere because Chinese-hosted ad networks try to inject content even on international routing. The 5 GB / 30-day plan at $11.99 is a good middle option. Saily is particularly worth considering for travellers who already use Nord Security products.

Pros
  • Bypasses the Great Firewall
  • Cheapest 1 GB plan among Firewall-bypassing options
  • Ad blocker meaningful given Chinese ad networks
  • Nord Security parent — solid privacy track record
Cons
  • Smaller per-region documentation than Airalo for China
  • No 10 GB option in the lineup
  • 20 GB is the only upper-tier option
  • Routing details less transparent than competitors

Drimsim

Backup only

Drimsim's China rate is $5/GB pay-as-you-go, the most expensive of the four — but it does bypass the Great Firewall via international routing. As a primary plan it's poor value, but as a backup eSIM in case your Airalo or Yesim fails on arrival in China, it earns its place. The single eSIM also handles a multi-country Asia loop including Hong Kong, Macau, Taiwan, and Japan without needing separate plans.

Pay-as-you-go
~$4.00/GB
No expiry
Balance never expires
Pros
  • Bypasses the Great Firewall
  • Single eSIM for China + Hong Kong + Taiwan + Japan
  • Balance never expires — convenient for repeat business travellers
  • Reliable backup if your primary fails in China
Cons
  • Most expensive per GB of any provider for China
  • Not recommended as a primary plan
  • Top-up flow can be problematic from inside China
  • Less polished app experience

How much data do you need in China?

China is the most important country in the world for understanding why an international eSIM matters more than a local one. The reason: the Great Firewall. A local Chinese SIM from China Mobile, Unicom, or Telecom routes all your traffic through Chinese DNS and blocks Google, Gmail, WhatsApp, Instagram, Facebook, Twitter, YouTube, the entire Google Maps app, most VPNs, and many Western news sites. An international eSIM, by contrast, routes your traffic out of China through the provider's home network — bypassing the firewall entirely without needing a VPN.

For tourists, this single fact changes data planning. You'll use Google Maps continuously (which doesn't work on local SIMs), check Gmail and WhatsApp constantly, and probably want Instagram or TikTok working normally. All of these are smooth on a roaming eSIM that routes outside China, and impossible on a local SIM without a working VPN.

Our recommendation: 5 GB minimum for any China trip — Maps, Gmail, and messaging burn through small plans quickly when everything routes internationally. 10 GB for a typical two-week China trip. 20 GB or more for video-call-heavy business travel.

Network coverage in China

China has three main carriers: China Mobile (the largest by far, the only one with full national coverage), China Unicom, and China Telecom. International eSIMs in China typically partner with China Mobile or China Unicom — Unicom is more common because it has international roaming agreements. Coverage is excellent in every Chinese city you'd visit as a tourist: Beijing, Shanghai, Xi'an, Chengdu, Guilin, Hangzhou, Suzhou, and the major Yangtze cities all have full 4G/5G.

Rural coverage on China Mobile reaches into the most remote western regions — the Tibetan Plateau, Xinjiang, and Inner Mongolia — at a level no other country comes close to. International eSIMs roaming on China Mobile share this coverage. The Great Wall sections near Beijing (Mutianyu, Jinshanling, Badaling) all have full signal. Smaller towns and rural villages are similarly well-covered.

Tips for using an eSIM in China

An international eSIM bypasses the Great Firewall. A local Chinese SIM does not. This is the single most important fact about mobile data in China for tourists. Roaming on Airalo, Yesim, Saily, or Drimsim, your traffic exits China through the provider's home network in Hong Kong, Singapore, or Europe — Google, WhatsApp, Gmail, Instagram, and YouTube all work normally. On a local SIM you'd need a working VPN, and most VPNs are blocked or unreliable inside China.

China is more expensive for eSIMs than most countries. The reason is that international roaming agreements with Chinese carriers are costly to maintain. Airalo's China prices are 30-50% higher than equivalent plans for European countries. This is the cost of bypassing the Firewall.

WeChat is mandatory for daily life. Restaurants, taxis, transit cards, and even tourist sites in China are increasingly Alipay/WeChat Pay only. Foreign credit cards work in luxury hotels and major chain stores but rarely elsewhere. Set up WeChat Pay or Alipay before your trip and link an international card if possible. Both apps work on international eSIMs without issue.

Beijing, Shanghai, and Shenzhen have extensive 5G. All three major Chinese carriers have rolled out 5G across the major cities, and international eSIMs roaming on China Mobile or Unicom generally connect automatically. Xi'an, Chengdu, Guangzhou, and most provincial capitals are also 5G-enabled.

Why eSIM is the best choice in China

China is the clearest case for an international eSIM over a local SIM anywhere in the world. A local Chinese SIM puts you behind the Great Firewall — no Google, Gmail, WhatsApp, Instagram, Facebook, Twitter, or YouTube — and forces you into a working VPN to access anything from outside China. Most popular VPNs are blocked or unreliable inside the country.

An international eSIM sidesteps this entirely by routing your traffic through the provider's home network outside China. Google Maps, Gmail, WhatsApp, and Instagram all work as if you were anywhere else in the world. The premium you pay for the international eSIM (vs a much cheaper local Chinese SIM) is essentially a bypass fee for the firewall, and for most tourists it's worth every cent.

Frequently asked questions

Yes — this is the single most important reason to use an international eSIM in China. Airalo, Yesim, Saily, and Drimsim all route your data traffic out of China through their home networks (typically via Hong Kong, Singapore, or Europe), which means Google, Gmail, WhatsApp, Instagram, Facebook, Twitter, and YouTube all work normally. A local Chinese SIM forces all traffic through Chinese DNS and blocks these services unless you have a working VPN.
Two reasons. First, international roaming agreements with Chinese carriers (China Mobile, Unicom, Telecom) are costly to maintain — Chinese telecoms charge premium wholesale rates to international partners. Second, the international routing infrastructure used to bypass the Great Firewall adds backend costs. The premium you pay (typically 30-50% more than European plans) is essentially a bypass fee for the firewall and access to Western services.
Yes, on any of the four international eSIMs on this page. Google Maps doesn't work at all on local Chinese SIMs (it's blocked by the Great Firewall and the underlying API calls fail), so a roaming eSIM is the only practical way to use it as a tourist. Apple Maps and Bing Maps also work on international eSIMs in China. Baidu Maps is the local alternative if you prefer it but it's Chinese-only.
Yes. The Great Wall sections near Beijing — Mutianyu, Badaling, Jinshanling, Simatai — all have reliable cellular signal from China Mobile and China Unicom. International eSIMs roaming on these networks get the same coverage. The Forbidden City, the Terracotta Warriors at Xi'an, the Bund in Shanghai, and almost every major tourist site in China are well-covered.
Get a dedicated China plan. Hong Kong SIMs roaming into China are typically expensive and may not bypass the Great Firewall depending on the carrier. Airalo, Yesim, Saily, and Drimsim all sell purpose-built China plans that route internationally and are priced for the use case. If your trip combines China and Hong Kong, look for a plan that covers both — Airalo offers separate but compatible plans.
