China's Mobile Networks — What Travelers Need to Know
China is the one destination where you do not want the local internet — you want a roaming connection that exits the country. China's mainland networks sit behind the Great Firewall, which blocks Google, WhatsApp, Instagram, Gmail, YouTube, most Western news sites, and many VPN apps.
An international travel eSIM works differently. It roams on a Chinese tower but routes your data out to a foreign gateway (often Hong Kong, sometimes Singapore), so the firewall doesn't apply — Google, WhatsApp, Instagram, and Gmail all work with no VPN. The catch: this only holds on mobile data. The moment you join hotel, café, or airport Wi-Fi, you're back on the censored Chinese internet.
There's a second reason a travel eSIM is the practical choice. China opened a domestic eSIM to its three carriers in October 2025, but it still requires a Chinese national ID for in-person verification — so foreign tourists can't use it. A local physical SIM needs your passport and sometimes a facial-recognition scan. An international travel eSIM avoids all of this.
China has four licensed mobile operators. Three of them — China Mobile (CMCC), China Telecom, and China Unicom — are the carriers travel eSIMs roam on. The fourth, China Broadnet, is a small 5G-focused new entrant that isn't relevant to visitors. When you buy a travel eSIM for China, it connects to one or more of the big three.
The Three Major Networks Compared
| China Mobile (CMCC) | China Telecom | China Unicom | |
|---|---|---|---|
| Mobile subscribers (Q3 2025) | ~1.009 billion | ~437 million | See notes* |
| 5G network users (end Sept 2025) | 622 million | 292.4 million | 225.2 million |
| Share of China's 5G subscriptions | ~53% | ~24% | ~20% |
| 4G coverage | Broadest; ~97% population (third-party estimate) | Strong, esp. south & west | Good, ~90% population (third-party estimate); strong in the north |
| 5G footprint | Largest; ~2.8M base stations targeted by end-2025 | Extensive in cities (co-built with Unicom) | Extensive in cities (co-built with Telecom) |
| LTE band type | TD-LTE (b39/40/41); modern phones fine | FDD-LTE — good foreign-device compatibility | FDD-LTE — best foreign-phone compatibility historically |
| Best for | Rural reach, second-tier cities, the far west, high-speed rail | Western & southern China; device compatibility | Northern China; device compatibility |
China Unicom reports a broader "~1.234 billion ubiquitous connectivity" figure that bundles IoT/M2M, so it is not a like-for-like phone-subscriber number. China had 4.55 million total 5G base stations across all operators by mid-2025. There is no reliable per-carrier published median-speed figure for China; the national all-operator median mobile download was 139.58 Mbps (Ookla, Jan 2025).

China Mobile (CMCC) — Broadest Nationwide Reach
China Mobile is the world's largest operator (~1.009 billion mobile subscribers) and the safest default if you'll leave the big cities. It has the most extensive 4G footprint — widely described as ~97% population coverage including small towns and rural areas (a third-party estimate, not an official figure) — and the largest 5G network, holding roughly 53% of China's 5G subscriptions.
Historically it used TD-LTE on bands 39/40/41, which some older or foreign phones handled poorly, though modern phones are fine.
Best for: Rural areas, second-tier cities, the Tibet/Xinjiang fringes, and high-speed rail. Many travel eSIMs roam here (reported, time-sensitive).
China Telecom — Western & Southern China
China Telecom is the second-largest by mobile subscribers (~437 million) and strongest in southern and western China — the Sichuan, Tibet, and Xinjiang corridors. It uses FDD-LTE, giving good foreign-device compatibility, and shares a co-built 5G network with China Unicom (the two pool 5G infrastructure). It holds about 24% of China's 5G subscriptions.
Some reseller sites call it the "weakest" of the big three nationally even while it's strong in the west and south — treat that characterization with caution.
Best for: Western/southern China and travelers wanting wide foreign-device compatibility.
China Unicom — Northern China & Device Compatibility
China Unicom holds about 20% of China's 5G subscriptions and is historically the most foreign-traveler-friendly for SIM compatibility (FDD-LTE). Its 4G is good (~90% population, a third-party estimate) and stronger in the north. It co-builds and shares its 5G network with China Telecom, and targeted continuous 5G-Advanced coverage in key areas across 300 cities by end-2025.
Best for: Northern China and travelers prioritizing device compatibility. It's commonly the network behind several travel eSIMs.
China Broadnet — Not for Tourists
China Broadnet (China Broadcasting Network) is the smallest of the four licensed operators, holding only ~3% of China's 5G subscriptions. It runs a 700MHz 5G network co-built with China Mobile (good propagation and indoor reach) and has been branded the fourth national carrier since 2022. It's included here only for completeness — travel eSIMs don't roam on it.
Which Network Does Each eSIM Provider Use in China?
This is the question most travelers actually need answered. The important caveat for China: these network assignments are reported by review sites, not officially disclosed by the providers, and they change often — Nomad's switch below is exactly the kind of change that happens. Where a provider's network is genuinely unknown, treat the underlying network as unknown rather than assuming one.
| Provider | Network(s) in China (reported) | Notes |
|---|---|---|
| eSIM-Now | China Mobile + China Unicom (both 5G) | Roams on China Mobile and China Unicom; data breaks out in Hong Kong (outside the Firewall) so Google/WhatsApp work without a VPN. Based on our current routing; network partners can change without notice |
| Airalo | China Unicom (5G-capable) | Data routed out of mainland China (roaming) — no VPN needed |
| Holafly | China Mobile (CMCC), 4G/5G | Valued for the broadest coverage incl. second-tier cities and rural areas |
| Nomad | China Unicom → China Telecom (by early 2026) | Reportedly switched; routes traffic out via Hong Kong. Highly time-sensitive |
| Saily | Unknown | Doesn't publicly specify; reported as data-only and not 5G-ready |
| Ubigi | China Telecom (4G/LTE, no 5G) | Reported |
Network assignments based on provider disclosures and independent testing as of 2026; carriers may change without notice. All competitor mappings here are reported by review sites, not carrier-disclosed. If you're unsure of a given provider's current network, assume most travel eSIMs connect to one or more of the three major carriers — China Mobile, China Telecom, or China Unicom.
Key takeaway: If your itinerary includes rural areas or the far west, choose a provider that includes China Mobile — it has the strongest coverage outside the big cities. eSIM-Now roams on China Mobile and China Unicom (both 5G; based on our current routing, network partners can change without notice).
Coverage by Region
Major Cities — All Networks Excellent
| City Tier / Example | 4G | 5G | Speed | Notes |
|---|---|---|---|---|
| Beijing / Shanghai / Shenzhen / Guangzhou | Excellent | Dense | Fast 5G | Carrier choice barely matters — base-station density is similar across the big three |
| Second-tier (Chengdu, Xi'an, Hangzhou, Chongqing, Wuhan) | Very good | Broad | Strong 5G in cores, 4G everywhere | China Mobile and the Telecom/Unicom shared 5G all perform well |
In any Tier-1 city, all three carriers perform well. National median mobile download was ~140 Mbps (Ookla, Jan 2025), with tier-1 city 5G typically higher. Real-world speed is gated more by the roaming route out of China than by the local radio, so your choice of eSIM provider won't matter much for urban-only trips.
Popular Tourist Routes
| Route / Area | Coverage | Carrier Matters? | Notes |
|---|---|---|---|
| Tourist sites (Great Wall/Mutianyu, Forbidden City, Terracotta Army, Zhangjiajie, Guilin) | Good 4G/5G at the sites | Slightly | Can dip on remote trail sections or canyon/mountain spots; China Mobile edges ahead at remote scenic spots |
| High-speed rail (Beijing–Shanghai, Chengdu–Chongqing) | Good along most routes | Slightly | Brief drops in tunnels and long mountain stretches; China Mobile generally reconnects fastest |
China Mobile has run 5G-Advanced rail pilots hitting 300+ Mbps in places. Expect intermittent signal in tunnels regardless of carrier, and buffer offline content for long rides. Download offline maps before visiting remote scenic spots.
Rural & Remote Areas
| Area | Coverage | Recommended Carrier | Notes |
|---|---|---|---|
| Rural villages / agricultural areas (eastern & central) | Near-universal 4G; 5G increasingly common | China Mobile | China has pushed 4G/5G into the vast majority of natural villages |
| Tibet (Lhasa & main corridor) | Cities/towns and main routes covered; remote valleys patchy | China Mobile / China Telecom | 5G in Lhasa; a Unicom-only eSIM may struggle off main roads. Tibet also needs a permit + organized tour |
| Xinjiang (Urumqi, Kashgar, desert/oasis routes) | Good in cities and on main highways; sparse in backcountry | China Mobile / China Telecom | 5G in larger cities; cross-network 5G roaming trialed to fill rural gaps. Heavy-surveillance region |
| Remote/high-altitude wilderness (Himalayan trekking, far-western deserts, grasslands) | Spotty to none off paved roads | China Mobile (most likely to hold a signal) | No eSIM guarantees coverage; carry offline maps, treat connectivity as best-effort |
If your itinerary includes the far west or deep rural China: make sure your eSIM connects to China Mobile (or China Telecom for Tibet/Xinjiang). Download offline maps before leaving the city.
Hong Kong & Macau — A Critical Quirk
| Area | Coverage | Behind the Great Firewall? | Notes |
|---|---|---|---|
| Hong Kong & Macau | Excellent, fast 5G | No — separate, uncensored networks | A mainland-China travel eSIM may or may not include HK/Macau |
This trips up a lot of travelers. Hong Kong and Macau run separate networks with open, uncensored internet — they are not behind the Great Firewall. Many "China" plans exclude them. If your trip crosses into Hong Kong or Macau, buy a Greater-China or Asia regional plan rather than a mainland-only China plan.
How a Roaming eSIM Beats the Great Firewall
This is the part that's unique to China. A few essentials:
- Use a roaming travel eSIM, not a local Chinese SIM/eSIM. The eSIM's data exits via a foreign gateway (often Hong Kong) so Google, WhatsApp, Instagram, and Gmail work with no VPN.
- Don't rely on Wi-Fi. On hotel, café, or airport Wi-Fi you're back on the censored network — mobile data is what gets you out.
- Don't count on a VPN as your primary tool. China blocks or throttles a large share of commercial VPNs, and they sit in an on-again/off-again legal grey area. A roaming eSIM is the more reliable path; keep a reputable VPN installed only as a Wi-Fi fallback.
- Set everything up before you fly. Install your eSIM, a backup VPN, Google Maps offline areas, WhatsApp, and any Western apps you need — their app-store pages and many VPN sites are blocked once you're inside China.
- Use a China-friendly map app. Google Maps is unreliable even with a VPN (location data is offset in China). Use Amap (Gaode, has an English mode) or Apple Maps on iOS, and save offline maps as backup.
- Know the Hong Kong-IP gotcha. A handful of apps (e.g. ChatGPT) can be geo-restricted from a Hong Kong IP even though the firewall itself is bypassed. Have a fallback.
- Set up WeChat and Alipay before arrival and link a foreign Visa/Mastercard — cash is increasingly hard to use, and these apps work with an international phone number. Confirm your phone supports eSIM and is carrier-unlocked.
See our phone compatibility checker to confirm your device, and the iPhone eSIM setup guide to install before you travel. eSIM-Now covers 140+ countries, so the same eSIM workflow works on your next trip too.
Does 5G Matter for Travelers in China?
Probably not. 4G speeds in China are already more than enough for maps, translation, social media, and video calls, and your real-world speed is limited more by the roaming route out of the country than by whether you're on 4G or 5G. 5G is a nice bonus in Tier-1 cities, but don't choose a provider on 5G alone — choose one whose coverage footprint matches where you're going (China Mobile for rural/west).
Check Official Coverage Maps
For carrier-level detail, check the operators' own sites (most are in Chinese and some are geo-blocked outside China) and the third-party maps:
- China Mobile — 10086.cn (Chinese; coverage via the 10086 app) and the Hong Kong-listed English investor site
- China Unicom — chinaunicom.com.cn (Chinese; often geo-blocked outside China)
- China Telecom — 189.cn (Chinese; often geo-blocked) and the English investor site
- GSMA Mobile Economy China — gsma.com/.../mobile-economy/china and GSMA SOMIC (English, market data)
- nPerf — nperf.com/en/map/CN (crowdsourced, all carriers — not official)
Get Connected Before You Land
eSIM-Now roams on China Mobile and China Unicom (both 5G), and your data breaks out in Hong Kong — outside the Great Firewall — so Google, WhatsApp, Instagram, and Gmail work with no VPN for most travelers (based on our current routing; network partners can change without notice). We still suggest installing a VPN before you fly as a fallback. See our Best eSIM for China guide for current plans and prices, and the China plans page for live pricing.
Buy your eSIM before departure, install the QR code at home, and you'll land in Beijing or Shanghai already connected — no scrambling for a VPN behind the Great Firewall.
