For most trips to China, the best eSIM is a single data-only plan that runs on China Mobile’s 5G network as the primary carrier, with China Unicom and China Telecom as backup networks. That gives you 3 network options in one eSIM. Plans start at $4.00. You scan a QR code to install it—no physical SIM card is needed—hotspot works, and tourist data plans don’t ask for a passport. The eSIM is designed with international data routing, so apps like Google and WhatsApp work in most cases without a separate VPN. From that $4.00 starting price, plans climb to 10 GB or more, and bigger plans run as long as 30 days. Prices change, so instead of pasting a table that goes stale, check the live list on the China eSIM page for current, up-to-date options.

How much does a China eSIM cost?
The cheapest option is $4.00. From there plans climb to 10 GB or more, and the bigger ones run as long as 30 days. Prices change, so instead of pasting a table that goes stale, check the live list on the China eSIM page.
Which network does a China eSIM use?
China Mobile is the largest carrier in China and supplies the main network. If it drops out, the eSIM falls back to China Unicom or China Telecom, so coverage holds up across the whole country. 5G comes through where the local network has it; elsewhere it drops to 4G LTE, which is still fine for maps and messaging.
Does Google and WhatsApp work?
Yes. The eSIM is designed with international data routing, so apps like Google, WhatsApp, Instagram and Gmail work in most cases without a separate VPN. Performance may vary by location.
How much data do you actually need?
Navigation eats about 100 MB a day. Messaging and social media add another 150–200 MB. So a normal week of maps, WeChat and the occasional photo upload lands around 2–3 GB total. Video is the exception: an hour of streaming is roughly 1 GB. If you plan to video-call or stream, that changes the math.
When is unlimited data worth it?
Only when you know you’ll stream or tether. If you’re on maps and messaging, unlimited is money you won’t use. But if you’re working remotely and hotspotting a laptop every day, a larger or unlimited plan is cheaper than buying a small one and running out.
Dual-SIM: keep your bank OTPs
A data-only eSIM leaves your physical SIM slot free, so your home number keeps receiving bank verification texts at no extra cost. That’s the setup to use if your bank still sends one-time passwords by SMS.
Arrival and getting around
At Beijing Capital or Shanghai Pudong airport, the airport express or an app taxi reaches the city. Around the cities, the metro runs on a rechargeable card, and Didi is the standard ride app. Apple Maps switches to the Amap database in China, so you can still get English directions.
How to install and activate
- Scan the QR code from your order email under Settings → Cellular → Add eSIM.
- Label the plan so you can tell it apart from your home SIM.
- Turn on data roaming for the eSIM once you land. The plan starts counting from the first connection.
Will my phone work with it?
Any carrier-unlocked phone that supports eSIM will work: iPhone XS or newer, Pixel 3 or newer, and Samsung Galaxy S20 or newer are the common ones. If your phone is locked to a carrier, unlock it first or the install will fail at the QR step.
Frequently Asked Questions About China eSIMs
Q1: Do I need to register with a passport?
No. Tourist data plans don’t ask for a passport upload or ID check under current carrier rules. Local laws can change, so it’s worth a quick check before you go.
Q2: Which network does the eSIM connect to?
China Mobile is the primary network, with China Unicom and China Telecom as backup. Your phone picks whichever has the strongest signal in that spot.
Q3: Can I use it as a hotspot?
Yes, hotspot and tethering are enabled on every plan. A laptop or a second phone can share the connection.
Q4: Do Google and WhatsApp work on the eSIM?
Yes. The eSIM uses international data routing, so apps like Google, WhatsApp and Instagram work in most cases without a separate VPN. Performance may vary by location.
Q5: When does the plan start counting?
From the first connection to a local network after landing, not from the moment you scan the QR code. Install it at home on Wi-Fi and activate on arrival.
Q6: Does it work outside the big cities?
Yes. China Mobile, China Unicom and China Telecom cover the whole country, including smaller cities, high-speed rail lines and rural areas, so you stay connected beyond Beijing and Shanghai.
Q7: Can I top up or extend it?
Topping up depends on the plan. The simplest option is to buy a longer plan up front if your dates are fixed; check the live plan list for what’s available.
Q8: Does WeChat and Alipay work?
Yes. WeChat and Alipay run over data, and the eSIM keeps them working so you can pay, message and order rides without a local number.
Q9: Will I get 5G everywhere?
5G appears where the local network has it — mostly cities and major transport lines. In between you’ll sit on 4G LTE, which handles navigation and messaging without a problem.
Q10: What’s the refund policy?
Refunds depend on whether the plan has been activated. If you buy and don’t install it, you’re usually covered; once it’s active, it’s non-refundable. The full terms are on the product page.
Bottom line
For a China trip, a single data eSIM on China Mobile with international data routing is the least-fuss option, and 2–3 GB covers a normal week. Pick the size that matches your video habit, install it before you fly, and you’ll have signal the moment you land. See the current plans here.
