China eSIM: Stay Connected Across the Middle Kingdom
Land in China online in minutes. A practical eSIM guide covering networks, data needs, and setup so you stay connected from Beijing to Shanghai.
Stepping off the plane in Shanghai with a dead phone is no fun, especially in a country where so much daily life runs through an app. A China eSIM gets you online the moment you land, no SIM-swapping at the airport and no surprise roaming bills.
Why use an eSIM in China
An eSIM is a digital SIM you install before you fly. You keep your home number active for calls and texts, and use affordable local data on the side. There's no plastic card to lose, no kiosk queue, and you can set everything up from your couch days before departure.
Instant delivery by email, ready before you travel
China has three nationwide operators: China Mobile, China Unicom, and China Telecom. Together they deliver strong 4G everywhere and expanding 5G across major hubs. Expect fast, reliable speeds in Beijing, Shanghai, and Guangzhou, with solid coverage in tourist regions like Xi'an and Chengdu. Our eSIM connects to the best available partner network automatically.
How to get connected
1. Buy your China eSIM online and check your email for the QR code.
2. Install by scanning the QR under your phone's cellular settings (do this on Wi-Fi before you leave).
3. Activate by enabling data roaming for the eSIM line when you arrive, and you're online.
How much data do you need
Light (1-3 GB): maps, messaging, occasional browsing for a short trip.
Medium (5-10 GB): daily social media, navigation, and photo uploads over a week or two.
Heavy (15 GB+): streaming, hotspot, and video calls for longer stays.
Many travellers add a plan with a VPN-friendly route in mind, since some Western apps are restricted on local networks.

FAQ
Is my phone compatible? Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Check for an eSIM option in your settings before buying.
When should I install it? Install at home on Wi-Fi a day or two before departure. Activation happens automatically once you land and switch on data roaming for the eSIM.
Can I keep my WhatsApp number? Yes. Your WhatsApp stays tied to your original number, which remains active on your physical SIM while the eSIM handles data.
Yes. As long as your phone is eSIM-capable and carrier-unlocked, a HelloSIM eSIM connects to China's mobile networks over roaming, so you get data as soon as you land. No physical SIM swap or local ID registration is needed.
Can I use a HelloSIM eSIM to access Google, WhatsApp and Instagram in China?
Often yes. Because a travel eSIM roams and routes your data through an international gateway rather than a local Chinese connection, apps normally blocked by the Great Firewall frequently work without a VPN. This depends on the plan's routing, so check the plan details and consider a backup VPN just in case.
Is my phone compatible with a China eSIM?
Most iPhones from the XS/XR (2018) onward and recent Google Pixel, Samsung Galaxy S/Note/Z, and other flagship Android phones support eSIM. Note that some Galaxy and other models bought within mainland China have eSIM disabled, so a device purchased outside China is safest.
How do I install a HelloSIM eSIM for China?
After purchase you receive a QR code by email. On your phone go to the cellular/mobile settings, choose 'Add eSIM' or 'Add data plan', scan the QR code, and follow the prompts. Do this over Wi-Fi before you travel.
How do I install the eSIM on an iPhone?
Go to Settings > Cellular > Add eSIM > Use QR Code, then scan the code from HelloSIM. Label the plan, keep your home line for calls if you like, and set the HelloSIM line for cellular data.
How do I install the eSIM on an Android phone?
On most Androids go to Settings > Network & internet > SIMs > Add eSIM (or the '+' next to SIMs), then scan the HelloSIM QR code. Wording varies slightly by brand such as Samsung, Pixel or Xiaomi.
Should I install the eSIM before I fly to China?
Yes, install it before departure while you have reliable Wi-Fi. Installing and activating are separate steps, so you can set it up at home and only enable it when you arrive in China.
When should I activate my China eSIM?
For most HelloSIM plans the validity clock starts when the eSIM first connects to a network in China, so activate on arrival. Some plans start on first use or a fixed date, so confirm the activation rule for your plan before travelling.
Which networks does HelloSIM use in China?
HelloSIM roams on China's major operators, typically China Mobile and China Unicom, which together cover virtually all populated areas. Your device selects the best available partner network automatically.
Is there 5G with a China eSIM?
Yes, 5G is widely deployed across major cities like Beijing, Shanghai, Guangzhou and Shenzhen, and if your phone and plan support it you can connect to 5G there. Outside big cities you will usually be on fast 4G LTE.
How is the mobile coverage in China?
Coverage is excellent in cities, along high-speed rail lines and across most of the country thanks to heavy network investment. Very remote mountain and desert regions in the far west can be patchier, as anywhere.
How much data do I need for a week in China?
For a week of maps, messaging, social media and browsing, roughly 3-5 GB suits most travelers. Add more if you stream video, use lots of video calls, or rely on hotspot for a laptop.
How much data do I need for two weeks in China?
A two-week trip with everyday use typically runs about 6-10 GB. Heavy users who stream, navigate constantly or tether should look at larger or unlimited-style plans.
What do China eSIM data plans cost?
Prices vary by data amount and validity, but travel eSIMs for China are generally priced per-GB in affordable ranges, with bigger bundles giving a lower cost per GB. Check HelloSIM's current China plans for exact figures.
Can I tether or use a hotspot with my China eSIM?
Yes, HelloSIM data plans support hotspot and tethering, so you can share your connection with a laptop, tablet or travel companion. Remember that tethering uses your data allowance faster.
Can I keep my home phone number while using the eSIM in China?
Yes. The eSIM adds a second line for data while your home SIM or eSIM stays active for calls and texts. Keep home data roaming off to avoid surprise charges and use the HelloSIM line for internet.
Does the China eSIM come with a phone number for calls and texts?
HelloSIM China plans are data-only, so there is no local number for regular voice calls or SMS. You can still call and message over the internet using WhatsApp, WeChat, FaceTime, Telegram or similar apps.
How do I make calls in China with a data-only eSIM?
Use internet calling apps such as WhatsApp, WeChat, FaceTime, Signal or Skype over your eSIM data. Locals in China rely heavily on WeChat, so it is worth having installed.
What APN settings do I need for the China eSIM?
Most eSIMs configure the APN automatically. If data does not work, HelloSIM provides the correct APN to enter manually under your cellular data settings, and you should make sure data roaming is turned on for the eSIM line.
Do I need to turn on data roaming for my eSIM in China?
Yes. Because a travel eSIM connects to Chinese networks as a roaming partner, you must enable data roaming for the HelloSIM line. Keep roaming off for your home line so it is not billed.
Will I have internet at the airport when I land in China?
Yes, if you installed the eSIM beforehand it should connect shortly after you land and switch off airplane mode at major airports like Beijing Capital, Shanghai Pudong or Guangzhou Baiyun. Give it a couple of minutes to register.
What do I do if my China eSIM shows no service or won't connect?
Toggle airplane mode on and off, confirm data roaming is enabled for the eSIM line, and check the eSIM is set as your data line. If it still fails, manually select a network like China Mobile or China Unicom in settings, or restart the phone.
My eSIM isn't registering on a network in China, what should I try?
Restart your phone, ensure the HelloSIM line is enabled and set for data, turn on data roaming, and try a manual network search. Registration can take a few minutes after arrival, and make sure your plan has been activated.
Can I top up or add data if I run out in China?
Yes. You can top up your existing HelloSIM plan or buy a new data package from your account without needing a new QR code in most cases, so you stay connected without swapping anything.
What happens when my China data plan runs out?
Data simply stops once the allowance or validity ends, with no bill shock since plans are prepaid. You can top up or purchase a fresh plan to keep going.
Can I use the same eSIM in Hong Kong, Macau or Taiwan?
Not necessarily. Mainland China plans often do not cover Hong Kong, Macau or Taiwan, which are separate. Choose a regional Asia plan or a dedicated plan if your trip includes those destinations.
Is there a regional plan that covers China and nearby countries?
Yes, HelloSIM offers regional Asia plans that cover China alongside other countries in the region, which is handy for multi-country itineraries. Check the covered-country list before buying.
What is the emergency number in China?
Dial 110 for police, 120 for ambulance and medical emergencies, and 119 for fire. Emergency calls generally connect even without an active data plan or local number.
What are typical mobile data speeds in China?
In cities on 5G you can see very fast speeds, and 4G LTE across the country is generally quick and reliable for streaming, video calls and navigation. Actual speed depends on location, network load and your device.
Do I need to show ID or register the eSIM in China?
No. Local Chinese SIMs require passport registration, but a HelloSIM roaming eSIM needs no in-country ID check, so you skip the registration hassle entirely.
Will map apps and navigation work with the eSIM in China?
Yes, but note that Google Maps can be unreliable inside China. Because a roaming eSIM often reaches Google services, it can help, though many travelers also use Apple Maps or the local Amap/Baidu Maps apps. Download offline maps as a backup.
Should I download offline maps before my trip to China?
Yes. Save offline maps of cities like Beijing and Shanghai in Google Maps or Maps.me before you go, so you can navigate even if a service is blocked or you hit a dead zone.
Can I use WeChat Pay and Alipay with the eSIM?
Yes, your eSIM data lets you run WeChat Pay and Alipay, which are essential for payments in China. Set these up before your trip since many places prefer them over cash or foreign cards.
Which cities does the China eSIM cover?
All major cities are covered, including Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, Xi'an, Hangzhou and Chongqing, plus the towns and transport corridors in between.
Can I use the eSIM on high-speed trains in China?
Generally yes. China's high-speed rail network runs through well-covered corridors, so you will usually have signal, though it can drop briefly in tunnels or remote stretches at high speed.
How long is a China eSIM plan valid?
Validity depends on the package, commonly ranging from a few days up to 30 days. Pick a plan whose validity matches your trip length so you are not left short or paying for unused days.
Can I install the eSIM on more than one device?
No, each eSIM QR code is tied to a single device once installed and cannot be moved freely between phones. Buy a separate plan for each device that needs its own connection.
Can I get a refund on my China eSIM?
If an eSIM has not been installed or activated, it is typically eligible for a refund under HelloSIM's policy. Once activated and in use it generally cannot be refunded, so check the refund terms at checkout.
Will the eSIM drain my battery faster in China?
Running two lines and constantly searching in weaker-signal areas can use a bit more battery. To save power, disable your unused home line and carry a power bank for long sightseeing days.
Is using a travel eSIM legal in China?
Yes, using an international roaming eSIM as a visitor is fine, the same as roaming with your home carrier. You do not need any special permission to connect as a tourist.
What is a smart pre-trip checklist for a China eSIM?
Confirm your phone is unlocked and eSIM-capable, install the eSIM over home Wi-Fi before flying, keep the QR/confirmation email, download offline maps and key apps like WeChat, and switch on data roaming for the eSIM line once you land.
Can I use the China eSIM for work video calls and streaming?
Yes. On 5G or solid 4G, the eSIM handles Zoom, Teams, YouTube and streaming well, though these consume data quickly, so choose a larger bundle if you plan heavy video use.
