Do I need to register my passport to buy a SIM card in China?

Yes. China requires real-name registration for all SIM cards — physical and eSIM. You must present your original passport (valid for at least 6 months) with a valid Chinese visa. Airport kiosks, carrier stores, and online services all require this step. There are no legal workarounds, and unregistered SIMs from street vendors are frequently deactivated.

Can I use my home carrier's international roaming plan instead?

Technically yes, but you'll likely pay more and get less. Most international roaming plans charge $10–20/day for China, and speeds are often throttled. You'll also still hit the Great Firewall — your home carrier's roaming partner is still a Chinese network. A local SIM or travel eSIM is almost always cheaper and faster.

Which carrier works best with iPhone and Android phones from abroad?

China Unicom has the best foreign phone compatibility by a wide margin. It uses internationally standard LTE bands that work with US, European, and Australian phone models. China Mobile and China Telecom occasionally reject certain bands, especially on older phones or devices bought from US carriers like Verizon or AT&T.

Can I get a Chinese phone number without a physical SIM?

No. Chinese eSIMs for local numbers are not yet available to foreign tourists. The only way to get a +86 number is through a physical SIM card from one of the Big Three carriers. International travel eSIMs from Holafly, Airalo, Nomad, and Trip.com provide data only — no local number.

What happens if my SIM card stops working mid-trip?

First, check if your phone is carrier-locked. If it is, no Chinese SIM will work. If your phone is unlocked but the SIM died, visit the nearest carrier store with your passport. They can reactivate or replace it. Prepaid plans don't auto-renew, so make sure you top up before the expiry date — you can do this at convenience stores, carrier stores, or via the carrier's app (usually only in Chinese).

Is 5G available on tourist SIM plans?

Yes. All three carriers offer 5G on tourist plans in major cities. Real-world speeds range from 100–500 Mbps in Beijing, Shanghai, Guangzhou, and Shenzhen. Coverage on high-speed rail is 4G with intermittent tunnel drops. Rural and mountainous areas are still largely 4G.

China SIM Cards for Tourists: Which Carrier and Plan to Pick (2026)

You step off the plane at Beijing Capital Airport, bleary-eyed and rumpled, and suddenly realise: you have no signal. No WeChat. No Alipay. No Google Maps to tell you which terminal exit won’t strand you in a taxi queue for an hour.

Welcome to China, where connectivity isn’t just convenience — it’s survival. The good news? Getting a SIM card has gotten dramatically easier in 2026. The bad news? There are now more options than ever, and picking wrong means either burning cash or ending up with a plan that leaves you squinting at a loading spinner in a Shanghai subway tunnel.

Let’s fix that.

The Three-Headed Beast: China’s Big Three Carriers

China’s telecom market is a tidy oligopoly — three state-owned carriers, each with distinct strengths, irritating quirks, and pricing that seems designed to confuse. Here’s what you need to know.

China Mobile — The Rural King

China Mobile is the largest mobile network operator on the planet, with over 970 million subscribers. Its superpower? Coverage. If you’re planning to hike the Tiger Leaping Gorge, stare at the Potala Palace in Lhasa, or get lost in the grasslands of Inner Mongolia, China Mobile will keep you connected when the other two carriers tap out.

The catch: It’s the least foreign-friendly carrier. Airport kiosks have limited English support, and some international phone models — particularly older US-bought handsets — don’t play nice with its network bands. You’ll also pay a premium for that rural reach.

Best for: Adventurers, cross-country train travelers, anyone venturing beyond city limits.

Typical tourist plan: 8GB + 300 minutes for ¥158 (~$22) over 30 days. Or ¥198 (~$27) for “unlimited” data that throttles after you hit a soft cap.

China Unicom — The Tourist’s Best Friend

China Unicom is what you want if your trip is mostly cities, museums, and restaurants — which, let’s be honest, describes 90% of tourists. It has the best foreign phone compatibility (it uses the same LTE bands as most international phones), the most English-speaking staff at airport counters, and tourist plans that actually make sense.

The catch: Coverage drops off a cliff once you leave urban areas. Good luck getting a signal in a national park.

Best for: First-time tourists, city hoppers, anyone who values ease of setup over rural coverage.

Typical tourist plan: 20GB + 30 minutes for ¥200 (~$28) over 30 days. The ¥300 (~$42) option bumps you to 100GB, which is frankly absurd unless you’re planning to stream 4K video on the high-speed rail.

China Telecom — The Wild Card

China Telecom is the budget option, and it shows. Its short-term tourist packages start as low as ¥48 (~$7), making it the cheapest way to get a Chinese number. It also has the strongest 5G in southern China — Guangzhou and Shenzhen are its home turf.

The catch: Coverage outside the south is mediocre, and English support is scarce. Some US phone models simply refuse to work with it.

Best for: Budget travelers, southern China itineraries, short business trips.

Typical tourist plan: ¥48–138 (~$7–19) for 7-day packages with varying data allowances.

The eSIM Revolution: No Passport, No Queue, No Problem

The biggest change in China travel connectivity since the pandemic? eSIMs. Specifically, international roaming eSIMs that let you bypass the Great Firewall without breaking a sweat.

How Travel eSIMs Trick the System

Here’s the clever bit. Local SIMs from China’s Big Three sit inside the Great Firewall — Google, WhatsApp, Instagram, and your favourite news sites are all blocked. You need a separate VPN to reach them.

International eSIMs (from providers like Holafly, Airalo, Nomad, and Trip.com) connect through overseas networks via roaming agreements. Since they route through Hong Kong, Macau, or foreign data centers, they naturally bypass the Firewall. No VPN configuration. No wrestling with Shadowsocks. Just data that works.

The Trade-Off

| Feature | Local Physical SIM | Travel eSIM | |---------|-------------------|-------------| | Chinese phone number (+86) | Yes | No | | Works with WeChat Pay / Alipay | Fully | Partial | | Requires passport | Yes | No | | Bypasses Firewall | No (needs VPN) | Yes | | Activation speed | 15-30 min at airport | 2 min via QR code | | Price (30 days, 20GB) | ¥200 (~$28) | $13.99–$30 |

The big gotcha: you need a Chinese number (+86) to fully register WeChat Pay, Alipay, and DiDi (China’s Uber). Without one, you’ll be paying cash everywhere and wondering why your DiDi account throws errors. This is the single most important consideration in your decision.

The Power Move: Two SIMs, Zero Problems

Here’s what savvy repeat travelers do:

Trip.com eSIM (or similar) for data — installed before you leave home, activated with a QR code, Google and WhatsApp work out of the box.
China Mobile ¥8/month plan for a +86 number — this is China Mobile’s “number retention” plan. It gives you a Chinese phone number for SMS verification and occasional calls, at a laughably low ¥8/month (~$1.10). They don’t advertise it (you have to ask), and many store clerks will try to upsell you. Be firm.

This combo costs about $20–30 for a two-week trip and covers all bases. The eSIM handles your data needs. The ¥8 plan handles verification codes and emergency calls.

Where to Buy: Airport vs. Downtown vs. Online

Airport Kiosks

Convenient, English-friendly at major airports (PEK, PVG, CAN, SZX), but you’ll pay a 30–40% markup. Beijing Capital and Shanghai Pudong now have integrated service zones in the baggage claim area where you can buy from all three carriers under one roof. Shanghai Pudong even offers “Wi-Fi Easy Authentication” — snap a photo of your passport info page to get free airport Wi-Fi immediately.

Verdict: Best for convenience if you land tired and just want something that works.

Downtown Carrier Stores

Cheaper, wider plan selection, but expect limited English and potential queues. Bring your passport and prepare for some pointing at phrasebook translations.

Verdict: Worth the trip if you’re staying near a commercial district and have an hour to kill.

Online Pre-Order

Services like Trip.com let you order a SIM online and pick it up at the airport or have it delivered to your hotel. You still need passport registration, but the paperwork is handled in advance.

Verdict: The sweet spot for organised travellers who hate queues.

SIM Card Pricing Cheat Sheet (2026)

| Plan | Price | Data | Duration | Best For | |------|-------|------|----------|----------| | China Mobile 7-day | ¥58 (~$8) | 2GB | 7 days | Short business trip | | China Mobile 30-day | ¥158 (~$22) | 8GB | 30 days | Light user, rural travel | | China Unicom 30-day | ¥200 (~$28) | 20GB | 30 days | Most tourists | | China Unicom 30-day | ¥300 (~$42) | 100GB | 30 days | Heavy streamer | | China Telecom 7-day | ¥48–138 (~$7–19) | Varies | 7 days | Budget traveler | | MobiMatter eSIM | $13.99 | 20GB | 30 days | Best value eSIM | | Holafly eSIM | $54 | Unlimited | 20 days | Unlimited + built-in VPN | | Nomad eSIM | $10 | 5GB | 30 days | Light data needs |

The One Thing Nobody Tells You

Your phone’s IMEI is registered against your SIM at purchase. If you switch SIMs frequently (say, a local SIM for WeChat and a roaming SIM for data), you’ll need to make sure your phone is unlocked. Carrier-locked phones from the US or Japan often refuse Chinese SIMs entirely. Check your unlock status before you board the plane.

Also: do not buy a SIM from street vendors claiming “no passport needed.” These get deactivated within days, and you’ll lose your number mid-trip. Stick to official channels.

Which Should You Choose?

Short trip (1–7 days), city only: Trip.com eSIM or Nomad eSIM. No passport hassle, instant activation, firewall bypass built in.
Medium trip (1–3 weeks), mixed itinerary: China Unicom physical SIM (for the number) + an eSIM for data. The dual-SIM combo covers everything.
Long stay (1 month+): China Mobile or China Unicom local plan. Cheaper per GB, gives you a full-service number, and you can add a VPN separately.
Backpacking rural China: China Mobile physical SIM. That rural coverage is the difference between posting a sunset photo and vanishing into the void.

Don’t overthink this. The right choice is visible from your itinerary — cities, data, or villages will tell you exactly what you need.
