Staying connected in China requires some forethought, because your regular mobile plan almost certainly won’t work the way you expect.

Here’s what’s actually working in 2026, in order of convenience.

The VPN question (briefly)

Before getting into SIMs: you probably already know that many Western apps and websites are blocked in China. Google, Instagram, WhatsApp, most news sites. You’ll need a VPN to access these.

A SIM card doesn’t solve this problem on its own — a Chinese SIM is subject to the same restrictions. International roaming and certain eSIMs can sometimes bypass these restrictions, but not reliably. This guide covers connectivity; see a dedicated VPN guide for that topic.

Best for: Travelers who want a clean, pre-arrival setup with no in-country logistics.

eSIM providers like Airalo, Holafly, and Nomad offer China data plans you can purchase and install before departure. You download the eSIM to your phone while still at home, and it activates when you land.

Pros:

  • No airport hassle on arrival
  • No language barrier to navigate
  • Can keep your home number active on the same device (if your phone supports dual SIM)
  • Many providers route through non-Chinese carriers, which means some blocked apps may work without a VPN

Cons:

  • More expensive per GB than a local Chinese SIM
  • Data speeds can be inconsistent depending on the provider’s carrier agreements
  • Not available on older phones without eSIM support

Recommended providers: Airalo (most coverage options), Nomad (good data speeds), Holafly (good for European travelers)

What to buy: For a 10-day trip, 10GB is usually sufficient if you’re not streaming. Buy 15GB if you plan to use maps extensively.

Option 2: Local Chinese SIM

Best for: Longer trips (2+ weeks) or travelers comfortable with a small amount of in-country navigation.

The three main carriers — China Mobile, China Unicom, and China Telecom — all sell tourist SIM packages. China Unicom and China Mobile have the most English-friendly international tourist SIMs.

You can buy these at:

  • Airport arrival halls (all major international airports have carrier kiosks in or near the baggage claim area)
  • Carrier stores in cities
  • Convenience stores (limited options, mixed quality)

What you’ll need: Your passport. That’s it. The staff at airport kiosks are usually accustomed to foreign travelers and the process is straightforward.

Prices: As of the last verified date, tourist SIM packages typically run ¥50–150 for 30 days of data, depending on the carrier and data quantity. Far cheaper than international roaming.

The catch: Local SIMs are subject to the same internet restrictions as everything else in China. You’ll need a VPN for blocked apps.

Option 3: International roaming

Best for: Short trips (3 days or less) where convenience outweighs cost.

If your home carrier offers international roaming in China, it will work. The cost varies dramatically by carrier — some US and European providers include China in their international day passes ($10–15/day), others charge steep per-MB rates.

Check your carrier’s specific China policy before departure. Some carriers explicitly exclude China.

The advantage: Zero setup. Your number works, your apps work (mostly), your carrier handles it. The disadvantage: Expensive for anything beyond a quick business trip.

What to do about WhatsApp and messaging

This is the specific question most travelers actually have: How do I stay in touch with people at home?

If you have an eSIM or international roaming: WhatsApp, iMessage, and Signal generally work (sometimes unreliably with a local Chinese SIM).

If you have a local SIM and no VPN: Set up WeChat before departure and ask your contacts to reach you there. WeChat works perfectly on Chinese SIM cards — it’s a domestic app. Many people find that their contacts in China are already on WeChat anyway.

With a working VPN: Everything works on any SIM.

Practical recommendation

For most Western travelers taking a 1–3 week trip to China:

  1. Buy an eSIM before departure from Airalo or Holafly — 10–15GB for a typical trip
  2. Set up WeChat on your phone (for messaging with local contacts and mobile payments)
  3. Download your VPN and test it at home before you leave

That’s the setup. The rest you handle when you get there.
