Landing in China without a local phone number is like arriving at a party without an invitation. You can't use WeChat (the app that runs everything), can't pay with Alipay, can't hail a DiDi ride, can't navigate with Baidu Maps, and — if you're here for business — you can't even register a Taobao or 1688 account to shop.
Every year, thousands of foreigners overpay for SIM cards at airport kiosks, sign up for expensive tourist plans they don't need, or walk away without a Chinese number at all. I've lived in China for over a decade and helped countless expats, travelers, and business owners sort out their connectivity. In this guide, I'll show you exactly how to buy a cheap SIM card in China — the right way — with 2026 pricing, carrier comparisons, and insider tips most tourists never hear about.
Whether you're here for a week or a year, this guide will save you money and headaches.
Can Foreigners Buy SIM Cards in China?
Yes — absolutely. Foreigners can buy and use Chinese SIM cards legally. Since 2013, China has enforced a real-name registration system (实名制) for all mobile phone numbers. That means you'll need:
- A valid passport (mandatory — no exceptions)
- A Chinese visa or residence permit (in some cases, a tourist visa works)
- In-person registration with facial verification at the carrier's store
You cannot register a Chinese SIM card online or remotely as a foreigner. The process requires your physical presence.
2026 Update: In 2025, China's Ministry of Industry and Information Technology (MIIT) introduced the "明白办、放心用" (Understand Before You Buy, Use with Confidence) regulations. A key provision: carriers must offer the same plans to new and existing users. This means if you find a cheap plan, you can switch to it — even as a brand-new customer. It also means carriers can no longer force expensive contracts on foreigners.
China's 3 Major Carriers Compared
China has three state-owned telecom giants. Each has strengths and weaknesses. Here's how they stack up for foreigners in 2026:
| Factor | China Mobile (中国移动) | China Unicom (中国联通) | China Telecom (中国电信) |
|---|---|---|---|
| Market Share | Largest (60%+ subscribers) | Second largest | Third |
| Coverage | Best — nationwide, including rural/remote | Strong in cities, weaker in mountains/west | Strong in southern China, excellent indoor (700MHz) |
| Network Tech | 5G SA, 4G LTE, 3G TD-SCDMA | 5G SA, 4G LTE, WCDMA (best global roaming) | 5G SA, 4G LTE, CDMA2000 (legacy) |
| Foreigner Friendliness | Moderate | Best — most English-capable staff, GSM compatibility | Moderate — good in southern cities |
| Phone Compatibility | Best for Chinese-market phones | Best for foreign phones (global GSM/WCDMA bands) | Check carefully — some CDMA bands won't work |
| Price | Mid-range | Competitive | Often cheapest 保号 plans |
| Best For | Rural travelers, longest coverage | Most foreigners — compatibility + English | Southern China, budget long-term stays |
Which Carrier Should You Pick?
- Short-term tourist? → China Unicom. Your foreign phone is most likely to work, and you'll find more English-speaking staff.
- Traveling to rural Tibet, Xinjiang, or Inner Mongolia? → China Mobile. Their coverage in remote areas is unmatched.
- Based in Guangzhou or Shenzhen long-term? → China Telecom. Excellent indoor coverage in southern cities and the cheapest "keep your number" (保号) plans.
- Business traveler in Shanghai/Beijing? → Any of the three works well; Unicom edges ahead for international roaming.
How Much Does a Chinese SIM Card Cost? (2026 Prices)
China's SIM card pricing is remarkably affordable — if you know which plan to ask for. Most foreigners end up on overpriced "tourist plans" that cost 3–5x more than they should. Here's the real pricing landscape in 2026:
The "Keep My Number" Plans (保号套餐) — Cheapest Option
These are the cheapest plans available — designed to keep your number active with minimal monthly fees. Perfect if you only need a Chinese number for WeChat/Alipay verification and use WiFi most of the time.
| Carrier | Plan Name | Monthly Cost | Includes |
|---|---|---|---|
| China Telecom | 无忧卡 (Worry-Free Card) | ¥5/mo (~$0.70) | 200MB data, 30 min calls |
| China Unicom | 8元保号套餐 | ¥5–8/mo (~$0.70–$1.10) | 200MB data, 30 min calls |
| China Mobile | 8元飞享套餐 | ¥8/mo (~$1.10) | 30 min calls, 100MB data |
Insider Tip
Carriers don't advertise these plans prominently. You need to ask specifically for the 保号套餐 (bǎo hào tāo cān). Under the 2025 MIIT regulations, they're required to offer it to you — even if they initially say no.
Budget Plans (¥19–29/month) — Best Value
These are the sweet spot for most foreigners — generous data at rock-bottom prices. In 2026, carriers are competing aggressively with high-data internet-exclusive plans:
| Plan | Carrier | Monthly Cost | Data | Calls |
|---|---|---|---|---|
| 乐通卡 (LeTong) | China Unicom | ¥19–29 | ~295GB | 100 min |
| 银海卡 (YinHai) | China Mobile | ¥29 | ~245GB | 100 min |
| 星悦卡 (XingYue) | China Telecom | ¥29 | ~205GB | 100 min |
These "internet-exclusive" (互联网套餐) plans are usually only available through carrier apps or online channels — not at physical stores. That's a key reason to know your options before walking in.
Standard Plans (¥39–59/month)
If you need even more data or want unlimited calls:
| Plan Type | Price Range | Data | Best For |
|---|---|---|---|
| China Unicom 冰激凌套餐 | ¥39–59 | 60–100GB | Heavy streamers |
| China Mobile 畅享套餐 | ¥39–59 | 60–100GB | Nationwide travelers |
| China Telecom 天翼畅享 | ¥39–49 | 80–100GB | Southern China users |
Tourist-Specific Plans (Convenient but Overpriced)
| Duration | Typical Price | Data Included |
|---|---|---|
| 7-day tourist SIM | ¥80–150 | 10–30GB |
| 15-day tourist SIM | ¥150–250 | 30–50GB |
| 30-day tourist SIM | ¥200–350 | 50–100GB |
Bottom Line on Pricing
A tourist SIM is easy but expensive. If you're staying more than 7 days, you'll save 50–70% by getting a regular prepaid plan at a city carrier store instead.
Where to Buy: Airport vs City Shops vs Online
This is where most foreigners make costly mistakes. Let's break down every option:
Option 1: Airport SIM Card Counters
Every major international airport in China has carrier kiosks in the arrival hall — including Beijing Capital (PEK) & Daxing (PKX), Shanghai Pudong (PVG) & Hongqiao (SHA), Guangzhou Baiyun (CAN), Shenzhen Bao'an (SZX), Chengdu Tianfu (TFU), Xi'an Xianyang (XIY), and most other international airports.
| Pros | Cons |
|---|---|
| ✅ Open right when you land | ❌ 30–50% more expensive than city stores |
| ✅ English-speaking staff (sometimes) | ❌ Only sell tourist/visitor plans (overpriced) |
| ✅ They handle registration on the spot | ❌ Limited plan options |
| ✅ No need to navigate to the city first | ❌ Staff may push commission-heavy plans |
Typical airport SIM card price: ¥100–300 for a short-term tourist plan with limited data. The same plan in the city would cost ¥30–80.
When to Buy at the Airport
If you need connectivity immediately (hotel booking issues, contacting someone, navigation) and don't mind paying a premium for convenience. Budget ¥100–150 for a basic 7-day tourist SIM.
Option 2: City Carrier Stores (营业厅)
The cheapest and most flexible option — if you know where to go.
How to find a carrier store:
- Search "中国移动/联通/电信营业厅" in Apple Maps, Baidu Maps, or Amap (高德地图)
- Look for stores near university areas or business districts — they're more likely to have English-capable staff
- Larger "flagship" stores (主营业厅) have more authority to offer special plans
What to bring:
- Original passport (not a photocopy)
- Your unlocked phone
- Cash or mobile payment (some stores don't accept foreign cards)
- Patience — the process takes 30–60 minutes
| Pros | Cons |
|---|---|
| ✅ Lowest prices — same plans locals get | ❌ Limited English in smaller cities |
| ✅ Full range of plans available | ❌ Need to get to the city first |
| ✅ Can ask for the cheapest 保号套餐 | ❌ Registration process takes time |
| ✅ Staff can help set up your phone | ❌ Some stores may claim "foreigners can't get this plan" |
Option 3: Online Purchase & eSIM
For physical SIMs: You generally cannot buy a Chinese SIM card online as a foreigner — the real-name registration requires in-person identity verification.
For eSIM (data only): Several international eSIM providers offer China data plans:
| Provider | China Plan | Price | Notes |
|---|---|---|---|
| Airalo | 1–20GB | $4.50–$52 | Data only, no Chinese phone number |
| Nomad | 1–20GB | $5–$48 | Data only |
| Holafly | Unlimited | $19–$69 | Data only, pricier |
| Roamless | Pay-as-you-go | $0.02/10MB | Data only |
Critical eSIM Limitation
eSIMs give you internet access only — no Chinese phone number. Without a Chinese number, you cannot register for WeChat, Alipay, Taobao, DiDi, or any Chinese app that requires SMS verification.
Quick Comparison
| Factor | Airport | City Store | eSIM |
|---|---|---|---|
| Price | ¥¥¥ (expensive) | ¥ (cheapest) | ¥¥ (mid-range) |
| Convenience | ★★★★★ | ★★★ | ★★★★★ |
| Chinese Phone Number | ✅ Yes | ✅ Yes | ❌ No |
| Plan Options | Limited | Full range | Fixed data plans |
| English Support | Sometimes | Rare | App-based |
| Best For | Immediate needs | Best value overall | Backup data |
Step-by-Step: How to Buy a SIM Card in China
Here's the exact process to get your China SIM card, optimized for the best price and least hassle:
Step 1: Prepare Before You Go
- Unlock your phone — confirm it's carrier-unlocked before arriving in China
- Check frequency bands — your phone should support at minimum: 4G LTE Bands 1, 3, 5 (Unicom/Telecom) or Bands 1, 3, 8, 34, 38, 39, 40, 41 (China Mobile)
- Bring your passport — original, physical passport
- Download carrier apps — 中国移动, 中国联通, or 中国电信
Step 2: Choose Your Carrier and Store
Based on the comparison above, pick your carrier. Use your map app to find the nearest carrier store (营业厅). In major cities, aim for a flagship store near a university or expat area.
Step 3: Visit the Store
Walk in and present your passport. Here are some useful phrases:
- "I'd like to buy a SIM card" → 我想买一张手机卡 (wǒ xiǎng mǎi yì zhāng shǒu jī kǎ)
- "I'm a foreigner" → 我是外国人 (wǒ shì wài guó rén)
- "What's the cheapest plan?" → 最便宜的套餐是哪个？ (zuì pián yi de tào cān shì nǎ ge?)
- "I want the 保号 plan" → 我想办保号套餐 (wǒ xiǎng bàn bǎo hào tào cān)
Step 4: Complete Registration
The store staff will:
- Photocopy your passport
- Take your photo (facial recognition verification)
- Register the SIM under your name
- Activate the SIM card
This takes 30–60 minutes. The SIM card itself is usually free — you just pay for the first month's plan.
Step 5: Set Up Your Phone
Insert the SIM, configure APN settings if needed (most phones auto-detect), and test:
- Can you make a call?
- Does mobile data work?
- Can you receive SMS?
Step 6: Register for Essential Apps
Now that you have a Chinese phone number, immediately register for:
- WeChat (微信) — your primary communication tool
- Alipay (支付宝) — mobile payments
- DiDi (滴滴) — ride-hailing
- Meituan (美团) — food delivery
- Taobao (淘宝) — shopping guide for international buyers
How to Choose the Right Plan
For Tourists (1–14 days)
Recommendation: Airport tourist SIM or a city-store prepaid plan.
- Budget: ¥80–150 at the airport, or ¥30–60 at a city store
- Data needed: 10–30GB is plenty for maps, WeChat, and browsing
- Carrier: China Unicom (best phone compatibility)
For Short-Term Residents (1–3 months)
Recommendation: Visit a city store and get an internet-exclusive plan.
- Budget: ¥29–39/month
- Data needed: 100–300GB (the LeTong Card at ¥19–29/month is unbeatable value)
- Carrier: China Unicom or China Mobile
For Long-Term Residents / Expats (6+ months)
Recommendation: 保号 plan (¥5–8/month) as your base, with data add-ons as needed.
- Budget: ¥5–29/month depending on usage
- Carrier: China Telecom for the cheapest 保号 plan (¥5), or China Unicom for best compatibility
For Business / Wholesale Buyers
Recommendation: China Unicom prepaid plan with a Chinese number.
- Why? You need the number to register Taobao/1688 accounts, set up Alipay, and communicate with suppliers via WeChat.
- Budget: ¥29/month for the LeTong Card (295GB — you'll never run out)
Pro Tip for Business Buyers
Having a Chinese number and Alipay account makes sourcing from Chinese platforms dramatically easier. But if navigating Chinese-only platforms isn't your thing, using a reliable buying agent like ChinaBuy Pro lets you skip the hassle entirely — they handle purchasing, quality checks, and international shipping for service fees from $2.99.
10 Tips to Save Money on Your China SIM Card
- Don't buy at the airport unless you have to. Same plan, 30–50% higher price. If your hotel has WiFi, grab your SIM at a city store the next day.
- Ask for the 保号套餐 (number-keeping plan). These ¥5–8 plans aren't advertised but are guaranteed under MIIT regulations. Just say the magic words.
- Buy through the carrier's app for internet-exclusive plans. Plans like the Unicom LeTong Card (¥19/295GB) are only available online — not in physical stores.
- Bring a friend who speaks Chinese. Even basic Mandarin skills can help you negotiate a better plan or push back when a store claims "foreigners can't get that plan."
- Avoid "international roaming" add-ons. Unless you're actually traveling to Hong Kong or Macau, you don't need these. They're pure upsell.
- Top up via the carrier's app or Alipay, not at convenience stores. Some stores add ¥5–10 "service charges" for top-ups.
- Check if your phone is truly unlocked before arriving. Some phones are "SIM-unlocked" but still have carrier-specific firmware.
- Use WiFi whenever possible. China has free WiFi everywhere — malls, restaurants, cafes, metro stations. Your mobile data plan is backup, not your primary connection.
- Register for plans using your passport number, not your visa. Your passport number stays the same even if your visa changes.
- Keep your SIM active with a ¥5 top-up monthly if you're on a 保号 plan. Carriers deactivate numbers after 90 days of non-payment.
Common Mistakes to Avoid
- Overpaying at the airport. The ¥200 "tourist plan" at the airport counter? Same data as a ¥30 city-store plan. Do your research or wait until you reach the city.
- Not checking phone compatibility. Your phone must support Chinese network bands. Most modern phones do, but verify before you arrive — especially CDMA-only phones on China Telecom.
- Accepting the first plan offered. Store staff are incentivized to sell expensive plans. Politely decline and ask for cheaper options. Under 2026 regulations, you have the right to any publicly available plan.
- Forgetting that eSIM ≠ Chinese phone number. An Airalo or Nomad eSIM gives you data but not a Chinese phone number. You'll still be locked out of WeChat, Alipay, and Taobao registration.
- Not registering your SIM properly. Using someone else's registered SIM is technically illegal in China. Always register under your own passport — it's the law and protects your number.
- Letting your number expire. If you stop paying, your number gets recycled after 90 days and assigned to someone else. Keep making small monthly top-ups if you want to keep it.
- Not realizing you can port your number. China supports mobile number portability (MNP) since 2019. You can switch carriers while keeping your number — no need to start from scratch.
Frequently Asked Questions
1. Can I buy a China SIM card before arriving in China?
Not a physical SIM with a Chinese phone number — real-name registration requires your passport in person. You can set up an eSIM (data only) before departure for immediate internet access on arrival, but you'll still need a local SIM for app registrations.
2. Will my phone work in China?
Most phones manufactured after 2020 support Chinese network bands. China Unicom is the most compatible with foreign phones (GSM/WCDMA/LTE bands used globally). iPhones, Samsung, and Google Pixels generally work well. Check your phone's supported bands against China's frequency allocations before arriving.
3. How much does a SIM card cost in China in 2026?
The SIM card itself is free — you only pay for the plan. Cheapest option: ¥5/month (China Telecom 保号). Best value: ¥19–29/month for 200–300GB data. Tourist SIMs at airports: ¥100–300 for limited plans.
4. Do I need a Chinese phone number to use WeChat?
Technically, you can register WeChat with a foreign number in some cases, but you'll face frequent verification issues and limited functionality. A Chinese phone number makes WeChat registration seamless and unlocks full features including WeChat Pay.
5. Can foreigners use China Mobile?
Yes, absolutely. Any foreigner with a valid passport can register for a China Mobile plan. However, China Mobile's phone compatibility with foreign devices can be tricky due to different 3G/4G band allocations. China Unicom is generally the safest choice for foreign phone users.
6. What's the best SIM card for a 2-week trip to China?
For a 2-week trip, a ¥30–60 prepaid plan from China Unicom at a city store offers the best value (30–100GB data). If you need connectivity immediately upon landing, budget ¥100–150 for an airport tourist SIM — then switch to a cheaper plan at a city store later.
7. Is China Unicom better than China Mobile for foreigners?
Generally, yes. China Unicom uses WCDMA and LTE bands that are compatible with most foreign phones out of the box. China Mobile uses TD-SCDMA (a China-specific 3G standard) and different LTE band combinations. Unicom also tends to have more English-capable staff in urban areas.
8. Can I top up my Chinese SIM card from abroad?
Yes — through the carrier's official app (中国移动/联通/电信), Alipay, or WeChat Pay. You'll need to set up mobile payment before leaving China for the easiest experience. Some carriers also accept international credit cards for app-based top-ups.
9. What happens if I lose my SIM card in China?
Visit any carrier store with your passport. They'll issue a replacement SIM with the same number, usually free of charge. This is another reason to always register your SIM under your own passport — it's the only way to recover a lost number.
10. Do I need a SIM card to use Taobao or 1688?
To browse Taobao or 1688, you only need internet access — an eSIM or WiFi works fine. But to create an account and make purchases, you need a Chinese phone number for SMS verification. If setting up all this sounds complicated, services like ChinaBuy Pro handle the entire shopping process for you — from finding products to international shipping — with service fees from $2.99 for your first eligible order. Orders under $300: $5.99 (single platform, up to 2 items; +$1.50 per additional item). Orders above $300: 3% (single platform, up to 3 items; +$3 per additional item).
