Whether you get a China eSIM with phone number depends on the specific plan. Travel eSIMs are commonly sold as data-only, which means mobile data but no local number, voice minutes or SMS. Read the plan page for number, calling and SMS terms. If it does not list them, assume you get data only.
This guide explains what a travel eSIM for China includes, what it leaves out, and how to cover calls, messages and verification codes. It also covers the phone checks that matter most for China.
China eSIM With Phone Number: What You Actually Get
An eSIM for China is a digital SIM profile you install by QR code or app. Some people search for an "eSIM card for China", but there is no physical card. The plan is delivered to your phone as a download.
A data-only plan supplies mobile data and nothing else. It does not come with an ordinary mobile number, carrier voice minutes or SMS. If a particular plan includes a number, calling or texting, its plan page will say so. Do not assume it does when the page is silent.
- Included on data-only plans: mobile data for maps, messaging apps, payment apps and browsing.
- Not included on data-only plans: a phone number, regular voice calls and SMS.
- Depends on the plan: hotspot sharing, speeds, top-ups and any number. Check each plan's details.
Why Does China Avoid eSIM Devices? Phones Sold in Mainland China
It is better described as a controlled rollout than a ban. Apple says mainland China supports eSIM only on specific iPhone models. Huawei describes its domestic eSIM service as a commercial trial handled in participating carrier stores with an in-person ID check. Sources: Apple Support and Huawei Support.
The practical result is that eSIM support on phones sold in mainland China can differ from the same brand sold elsewhere. Apple also says an eSIM from a non-mainland provider cannot be installed while you are physically in mainland China on a mainland-China eSIM-capable iPhone. These rules can change, so confirm them before departure.
Check your phone before you buy
Do this before any purchase. Run your model through the eSIM device compatibility checker, then confirm the phone is carrier-unlocked.
- iPhone: go to Settings > General > About. An unlocked iPhone shows "No SIM restrictions" next to Carrier Lock or Network Provider Lock (Apple's lock check).
- Android: look in Settings > About phone, or ask your carrier whether the phone is unlocked. Menu names vary by brand and software version.
- Where it was sold: check the manufacturer's page for eSIM support on your exact model. This matters most if the phone was bought in mainland China.
Bank Texts and Verification Codes in China
A data-only eSIM cannot receive SMS codes sent to your home number. Keep your home SIM active on a second line and use the travel eSIM for data. Apple confirms Dual SIM keeps two numbers active for calls and messages while the iPhone uses one cellular-data network at a time (Apple Dual SIM).
Check your home carrier's roaming and SMS charges first, because receiving texts abroad may cost extra. Our guide to bank verification texts with a travel eSIM covers the details. Also ask your bank whether it offers app-based approval, which only needs data.
Calls and Messages Without a Local Number
WhatsApp messages and voice or video calls use an internet connection, not your plan's voice minutes (WhatsApp Help). That makes them workable on a data-only eSIM, if the app is reachable from where you are.
Registration is the catch. WhatsApp verifies a number by SMS or phone call (WhatsApp Help for iPhone). Set up and verify your accounts before you fly. If you hit trouble, see how to reverify WhatsApp without a home SIM.
Do not count on any app until you test it
Official travel advice says Chinese authorities control internet access, some services are permanently blocked, and access can change around sensitive dates (UK government travel advice). A travel eSIM does not guarantee that any given app will load.
WeChat is an app-based way to reach contacts who also use it. It does not give you a Chinese phone number, and it does not replace bank SMS. Whether a data-only plan is enough for your trip depends on which apps you need and how they verify your account. Make a short list of must-have apps and test them before relying on them.
Trips that include Hong Kong or Macao
Mainland China, Hong Kong and Macao can be treated differently on the same plan. Read the coverage list on the plan page. Our Asia eSIM guide to mainland China, Hong Kong and Macao explains the differences before you pick one plan for all three.
Unlimited China eSIM: What to Expect
An unlimited China eSIM may still carry conditions. Plans marketed as unlimited can include daily high-speed allowances, speed reductions after a threshold or fair-use limits. Terms vary, so read the plan page for these points:
- Whether speed drops after a daily or total amount.
- Whether hotspot sharing is allowed.
- Whether you can top up.
- How many days the plan lasts, and when validity starts.
Validity works differently by plan. Some start when you install the eSIM, others on your first connection in China. Check the details and do not assume one rule fits every plan. Our guide to installing before travel explains the trade-offs.
How Much Data Do You Need in China?
Match data to your itinerary instead of buying the biggest plan. The table below is a general guide to relative use, not measured figures. Real use depends on your apps, video quality and settings.
| Activity | Relative data use (general guide) |
|---|---|
| Text messaging | Very low |
| Maps and navigation | Low |
| Social media scrolling | Medium, higher with video |
| Video calls | High |
| Standard-definition streaming | High |
| HD streaming | Very high |
A week of maps and messaging needs far less data than a week of daily video calls. Check your phone's cellular data usage screen after a day or two to see your real pattern. Then browse China eSIM plans and compare data amounts and validity side by side.
Step-by-Step eSIM Setup for iPhone and Android
Install the eSIM before departure while you have reliable Wi-Fi. Menu names vary by model and software version, so follow the on-screen wording on your phone and the plan's own instructions.
iPhone
- Connect to Wi-Fi and open Settings > Cellular (or Mobile Service).
- Tap Add eSIM, then scan the QR code or follow the plan's instructions.
- Label the lines, for example "Home" and "China Data".
- Keep the Home line on if you need bank texts.
- Under Cellular Data (or Mobile Data), select the travel eSIM line.
- Check the plan instructions on Data Roaming. Many plans ask you to turn it on for the travel eSIM line only. Keep it off for the home line.
- Turn off Allow Cellular Data Switching if you want to avoid data on the home line.
Android
- Connect to Wi-Fi and open Settings > Connections > SIM manager (Samsung), or Settings > Network & internet > SIMs (Pixel and others).
- Choose Add eSIM or Download a SIM, then scan the QR code or use the plan's activation details. Pixel owners can also check Google's Pixel help.
- Rename the lines so you can tell them apart.
- Set the travel eSIM as the mobile data line. Turn on its data roaming only if the plan instructions say so, and keep roaming off on the home line.
- Leave the home SIM on for calls and texts if needed.
For more on which line to switch on, read which line should have data roaming on.

Frequently Asked Questions
Can I get a China eSIM with a phone number?
It depends on the plan. Travel eSIMs are commonly sold as data-only, with no phone number, voice minutes or SMS. If a plan includes a number, the plan page will say so. Check the details before buying.
Why does China avoid eSIM devices?
It is better described as a controlled rollout than an outright ban. Apple says mainland China supports eSIM only on specific iPhone models. Huawei describes its domestic eSIM service as a commercial trial with in-person ID checks at participating stores. Rules change, so verify your phone's support before you travel.
Will WhatsApp work in China with a travel eSIM?
Not guaranteed. WhatsApp uses data for messages and calls, but official travel advice says internet access is controlled and some services are blocked. Test your key apps before relying on them. Have a backup such as WeChat for contacts who use it.
Can I receive bank texts while using a data-only eSIM?
Not on the travel eSIM itself. Keep your home SIM active on a second line to receive SMS codes, and check your carrier's roaming and SMS charges first. Some banks also offer app-based approval, which only needs data.
Is an unlimited China eSIM really unlimited?
It depends on the plan. Unlimited offers can include daily allowances, speed reductions or fair-use rules. Read the plan terms for speed limits, hotspot rules and top-up options. Do not assume full-speed data all day.
Should I install my China eSIM before I fly?
Yes, ideally over Wi-Fi before departure. Some plans start their validity at install and others on first connection, so check which applies. Install, label the lines and test mobile data settings at home so you can fix problems before you land.
