China is a digital special case for travelers: the Great Firewall blocks Google, WhatsApp, Instagram, Facebook, YouTube, Twitter and thousands of other services. Anyone using a local prepaid SIM there is cut off from the internet we're used to without a VPN. The elegant solution: a travel eSIM with foreign routing. It bypasses the firewall automatically — without a VPN app, configuration or hidden costs.
The technology, explained simply
The Great Firewall ("Golden Shield Project") works on multiple layers: DNS manipulation, IP blocking, deep packet inspection, traffic-density filtering. With a local China SIM, your data traffic runs unprotected through these filters — anything that's not whitelisted is rejected or slowed down.
A travel eSIM, by contrast, routes your traffic through an encrypted roaming tunnel to the foreign home network. From the Chinese authorities' perspective this is simply "roaming traffic from a foreign tourist" — by definition that isn't filtered (otherwise no German handset would work in China at all). The data only emerges in Hong Kong, Singapore or the US and flows out from there into the open internet.
Which travel eSIM works best in China?
From real-world tests and trip reports 2025/26:
| Provider | Sample plan | Routes via | Verdict |
|---|---|---|---|
| Airalo Chinacom | 5 GB / 30 days ~€14 | Hong Kong | Very reliable, recommended |
| Simbye China | 5 GB / 15 days ~€14 | Hong Kong / Singapore | Stable, good speeds |
| Holafly China Unlimited | Unlimited 7 days ~€29 | Hong Kong | Works, but pricier + fair-use throttle |
| Nomad China | 5 GB / 30 days ~€13 | Hong Kong | Works similarly to Airalo |
| Ubigi China | 3 GB / 30 days ~€14 | France (Orange) | Works, higher latency due to EU routing |
| Local China Mobile SIM | 5 GB ~€5 at airport | Direct China | NOT recommended — everything censored |
Airalo Chinacom
The current default tip for China trips. Routing goes through Hong Kong (CSL Mobile), so you bypass the firewall automatically. Realistic speeds in Beijing/Shanghai of 30–80 Mbps, similar in Chengdu, Guangzhou and Xi'an. Activation classic via QR code.
Simbye China
A slightly cheaper alternative to Airalo. Routing varies between Hong Kong and Singapore — both bypass Chinese censorship. Perfect for backpackers and the price-conscious. Downside: slightly higher latency on video calls, but streaming and browsing flow smoothly.
Holafly China Unlimited
The only "real" unlimited plan for China — no data cap, no throttling on basic usage. But: hotspot cap of 500 MB/day, fair-use throttling at extreme streaming. Worth it only if you really need a lot of data (live streaming, large video uploads). For normal trips, Airalo or Simbye are cheaper.
Beware of local China-Mobile SIMs
A China Mobile / China Unicom / China Telecom prepaid SIM at the airport is cheap (€5–10), but goes straight through the Great Firewall — Google, WhatsApp, Instagram, YouTube and Facebook are blocked. Only usable with a VPN, and VPNs are a legal gray area in China. Not recommended for tourists.

Coverage in the most important Chinese travel regions
Beijing (Forbidden City, Tian'anmen, Great Wall): 4G/5G throughout the city — China Mobile, China Unicom and China Telecom compete aggressively for speed in the capital. Travel eSIMs with Hong-Kong roaming bypass the firewall blanket-style. On the Great Wall (Mutianyu, Jinshanling): 4G at the main entrances, patchy on remote stretches of wall.
Shanghai (Bund, Pudong, Yu Garden, French Concession): Seamless 4G/5G coverage. Pudong skyline and Bund promenade continuously served. Maglev train from Pudong Airport to the city center: 4G during the ride at least sporadically. Streaming, video calls, fast uploads work everywhere — provided your roaming partner bypasses the firewall.
Xi'an (Terracotta Army, City Wall, Giant Wild Goose Pagoda): Inside the city walls 4G is strong. Terracotta Army (40 km outside): 4G via China Mobile at the complex, weaker in the halls themselves. The route to the complex has no gaps.
Chengdu (Panda Research Center, Sichuan cuisine, Tibet borderlands): 4G/5G in Chengdu city. The panda research center: well covered. Routes heading west (Mt. Emei, Leshan Buddha): 4G in the valley, weaker at higher altitudes. Tibet trips require separate travel permits and are restricted.
Guilin / Yangshuo (karst landscape, Li River): 4G is stable in the urban areas of Guilin and Yangshuo. On bamboo-raft tours along the Li River between Guilin and Yangshuo: regular dead spots. For checking your location, the reception window at boarding and disembarking points is enough.
Yunnan (Lijiang, Dali, Shangri-La): 4G throughout Lijiang Old Town and Dali. Shangri-La (3,200 m altitude, Tibet borderland): 4G in the urban area, weak off-trail. Tiger Leaping Gorge trekking: often offline.
Hong Kong (separate Special Administrative Region): Important: Hong Kong is not part of the Great Firewall — Google, Facebook, WhatsApp work normally here. Travel eSIMs with a "Greater China" plan (Airalo, Simbye) use a regular local network in Hong Kong and the Hong-Kong routing trick to bypass the firewall on the mainland. 5G in Central, Tsim Sha Tsui and all business districts is blanket.
Which eSIM for which China trip?
| Trip type | Recommendation | Price range |
|---|---|---|
| Weekend in Shanghai or Beijing | Airalo Chinacom 3 GB / 7 days | around €9 |
| 2 weeks standard tour (Beijing → Xi'an → Shanghai) | Airalo or Simbye 5 GB / 15 days | around €14 |
| 3-4 weeks backpacking | Airalo 10 GB / 30 days + top-up | €22–30 |
| Heavy user (streaming, hotspot) | Holafly Unlimited 15 days | around €49 |
| China + Hong Kong + Macau tour | Greater China regional plan (Airalo) | around €25 |
Common questions about eSIMs in China
Do I really need no VPN in China with a travel eSIM?
Correct — with most travel eSIMs (Airalo, Simbye, Holafly, Nomad, Ubigi) you need no VPN. The reason: these eSIMs route your traffic through foreign home servers (e. g. Hong Kong, Singapore, USA). That automatically bypasses the Great Firewall — Google, WhatsApp, Instagram, Facebook, YouTube, Twitter all work normally. Exception: local Chinese prepaid SIMs (China Mobile, China Unicom) go directly through the censored network — there you very much do need a VPN.
Which travel eSIMs work most reliably in China?
Proven in practice: Airalo ("Chinacom" plan, very reliable), Simbye China bundles (Hong-Kong routing, fast), Holafly (its own China plan). Nomad and Ubigi also work. What you should not get: a local China SIM from China Mobile at the airport — those route unfiltered through the Great Firewall and everything ends up blocked.
Do ALL Google services work, or only some?
With a travel eSIM that uses foreign routing: Google Search, Gmail, Google Maps, Google Translate, YouTube, Google Drive, WhatsApp, Instagram, Facebook, Twitter, ChatGPT, Discord — it all works. Caveat: If you also want to use Chinese apps (WeChat, Alipay), those work too — they come from China. So you effectively have access to both internets at once. That's the biggest upside of travel eSIMs in China.
What about the speed hit from foreign routing?
Noticeable but usually acceptable. Because traffic goes through foreign servers you get higher latency (typically 100–200 ms instead of 30–50 ms in Europe) and slightly reduced throughput. Fine for: Maps, messaging, normal browsing, even video calls. Tricky: online gaming with low ping requirements, 4K streaming. In practice, most travelers don't notice because they use moderate amounts of data anyway.
What does a travel eSIM for China cost?
As of Q1 2026: 3 GB / 7 days from €9 (Airalo Chinacom), 5 GB / 15 days from €14, 10 GB / 30 days from €22, Unlimited 7 days from €29 (Holafly, with fair-use throttling). China plans are generally pricier than e. g. Thailand plans because of higher roaming costs from Chinese operators. Local tourist SIMs from China Mobile are cheaper (€5–8 for 5 GB), but without firewall bypass they're practically useless for tourists.
Do I need to register the SIM with my passport?
For local Chinese SIMs (China Mobile, China Unicom): yes — passport + a Chinese address (your hotel works), activation in a mobile shop, can take 30+ minutes. For travel eSIMs: no, no registration needed. That's the second big advantage besides bypassing the firewall.
Does mobile payment (Alipay, WeChat Pay) work with a travel eSIM?
Alipay and WeChat Pay work over data — regardless of which SIM. Both apps have been easier to set up for tourists since 2023 (international credit cards are accepted). You no longer need a Chinese phone number for registration — a German number is enough. In practice: download both apps before departure, verify with your German number + a passport scan, and paying at the counter works without cash.
Which apps should I install before traveling to China?
Mandatory: Alipay (or WeChat Pay) for payment — cash is barely accepted in China anymore. Highly recommended: Maps.me or OsmAnd (Google Maps works with the travel eSIM, but offline backup is wise), Pleco (Chinese-English dictionary). Optional: DiDi (China's Uber, often cheaper than taxi), Trip.com (booking train tickets). A VPN app doesn't hurt to have, but you usually don't need it with a travel eSIM.
Can I also use the eSIM in Hong Kong, Macau or Tibet?
Hong Kong and Macau are separate regions with their own mobile networks — many China eSIM plans don't include them. For Hong-Kong/Macau trips, get a separate Hong Kong eSIM or a regional "Greater China" plan. Tibet: coverage in Lhasa is OK, sparse off-trail. Tibet trips also require an official tour operator (permits) who usually handle mobile too. Xinjiang: heightened restrictions, possibly extra VPN throttling even on a roaming eSIM.
