China eSIM and SIM Cards for Foreigners: What Actually Works

Short answer: For most first-time visitors, buy a travel eSIM before you fly if your phone supports eSIM — you land already online, keep your home number, and avoid the airport SIM queue. Buy a local SIM at the airport or a carrier store only if you need a Chinese (+86) phone number, for example for app registrations that require local SMS. Whichever you choose, download offline maps and a translation pack before you fly, and do not assume every app or website from home will work on a local Chinese connection.

Your three options at a glance

Option 1: Travel eSIM — the simplest choice for most first-timers

A travel eSIM is a digital SIM profile you buy online from a global provider (well-known names include Airalo, Holafly and Saily, among others) and install by scanning a QR code at home. On arrival you switch mobile data to the eSIM and you are online without swapping any physical card. Your home SIM stays in the phone, so you can still receive calls and SMS on your home number if your phone supports dual SIM.

Before you buy: check these four things

• Is your phone unlocked and eSIM-capable? Carrier-locked phones cannot add an eSIM, and older phones may not support eSIM at all. Check your phone settings before you pay.
• Does the plan actually cover mainland China? A plan that covers only Hong Kong and Macau, or an “Asia” plan whose mainland coverage is unclear, is a different product. Read the coverage list before buying.
• How much data, and what happens after it runs out? Maps, translation and payments use modest data; video calls and video streaming use a lot. Check whether the plan throttles, stops, or lets you top up.
• How does it route your traffic? This matters for what works online (see below). Some travel eSIMs route traffic through servers outside mainland China; others use local roaming agreements. If a seller cannot explain the routing, treat claims about which apps work as uncertain.

Price ranges (2026 guides, not a price list). Short travel eSIM plans for China are commonly reported around US$20–60 for roughly 10–20 days of data, depending on the data allowance. Compare data amount and validity days, not just the headline price.

Option 2: Local SIM — get one if you need a Chinese number

A local SIM from China Mobile, China Unicom or China Telecom gives you a +86 number, local data rates, and the ability to receive SMS codes from Chinese apps. Airport counters at major airports (Beijing Capital, Shanghai Pudong, Guangzhou Baiyun) and carrier stores in cities sell tourist and prepaid plans.

What buying one actually involves

1. Bring your original passport — a photo of it is not enough. Staff scan it and take a face photo: this is China’s real-name registration, required by law for all SIMs, not a special tourist obstacle.
2. Allow extra time (roughly 10–20 minutes at a counter, longer if there is a queue) and test the SIM at the counter: open a map, load a page, and save your new number somewhere offline.
3. Ask three questions before you pay: how many days is the plan valid, how much high-speed data before throttling, and can you top up later without a Chinese ID card?
4. Keep your home SIM somewhere safe — you will want it again when you fly home.

Price ranges (2026 guides, not a price list). Local prepaid tourist SIMs are commonly reported around 100–200 CNY for about a month, often with roughly 10–20 GB of data. Exact allowances and prices vary by carrier, city and counter.

When a local SIM is worth the queue: stays of several weeks, or if you plan to register for Chinese apps that insist on a +86 number for SMS verification. When it is not: a one-week trip where maps, payments and messaging are all you need — an eSIM is less hassle.

Option 3: Home roaming — simplest, usually most expensive

Keep your own SIM and enable your home carrier’s international roaming or a China day pass. You keep your number and do nothing at the airport. The downsides are cost (roaming is usually the most expensive option per gigabyte), sometimes slower speeds, and — depending on your carrier’s roaming partner — the same internet filtering as a local connection. Check your carrier’s China rate before you rely on this; a surprise bill is the classic roaming mistake.

What works online and what does not: the honest version

China’s internet is filtered. On a local connection (local SIM or hotel Wi-Fi), services commonly reported as blocked include Google Search, Gmail, Google Maps, YouTube, Facebook, Instagram, WhatsApp, Telegram and X. Services that work normally include WeChat, Alipay, DiDi, Amap/Baidu Maps, Trip.com and Apple iMessage/iCloud.

Some travel eSIMs route traffic outside mainland China, in which case many home apps keep working; others route through local partners, in which case the same filtering applies. Do not treat any eSIM as a guaranteed way to reach every blocked site — check the provider’s own description of routing, and have a backup plan either way:

• Download offline maps (Amap or Baidu Maps, plus your usual maps app’s offline area) and an offline translation pack before you fly.
• Agree with family how they will reach you: WeChat works on any connection; WhatsApp may not.
• Do not install or rely on circumvention tools you have not researched. This guide does not recommend any method of bypassing filtering, and you should check the rules that apply to you before using one.

Setting up your phone: checklist

• Phone unlocked? eSIM-capable? (for the eSIM route)
• eSIM installed at home and tested before departure, or local SIM plan chosen with passport packed in hand luggage
• Alipay and WeChat Pay set up — see how to set up Alipay and how to set up WeChat Pay
• Offline maps and translation pack downloaded
• Hotel address saved in Chinese characters (you will need it for taxis and delivery — see getting around Chinese cities)
• Hotel Wi-Fi password asked for at check-in, and a backup: do not depend on hotel Wi-Fi alone

Frequently asked questions

Do I need a Chinese phone number to use Alipay or WeChat Pay?

No. Both work with a home phone number and a passport. A Chinese number is useful for some other Chinese apps, not for payments.

Can I buy a SIM at the airport without speaking Chinese?

Yes, at the major international airports. Bring your passport, point at the plan you want, and test the SIM at the counter before leaving.

Will my travel eSIM give me a Chinese number?

Usually not. Most travel eSIMs are data-only. If a seller promises a +86 number, confirm exactly what kind of number it is and whether it receives SMS.

Is hotel Wi-Fi enough on its own?

No. Hotel Wi-Fi is a domestic connection subject to the same filtering as a local SIM, and it disappears the moment you leave the hotel. Arrange mobile data for the street, not just the room.

What if my eSIM does not work on arrival?

Check that mobile data is switched to the eSIM (not your home SIM), that data roaming is on for the eSIM, and that you selected the right plan. If it still fails, buy a local SIM at the airport or use hotel Wi-Fi while you contact the provider.
