Data-Only SIM in China: Cheap Browsing, No Number

TL;DR: the 30-second version

A day of typical Western roaming can cost more than a week of local Chinese data. Swap to a data-only SIM — no phone number, no calls, no SMS — and you keep maps, translation, video and the apps you already have, for a fraction of the price. Mid-2026 ballparks: 40-70 RMB (about USD 6-10) for a week of tourist data; monthly plans in the tens of RMB. Just bring your passport and twenty minutes.

The short answer

Yes, you can browse cheaply in China with no phone number attached. China Mobile, China Unicom and China Telecom all sell pure data products to foreigners and passport registration is standard. The one real trade-off: no SMS means you cannot register apps that demand a verification code — WeChat, DiDi, Alipay and banking apps all need one. For plain browsing, it is a great deal.

Why bother with a data-only SIM at all

Three reasons we see over and over. Tablets and portable hotspots never needed a “real” number — a data card turns them into full internet devices. Second, a second phone for navigation and video keeps your main number clean; numbers here attract spam within weeks of any shop or delivery rider getting yours. Third, the math: most Western roaming passes run USD 8-15+ per day, while a week of local data costs less than one of those days.

Two products share one name — and one is a trap

In an official carrier shop, you want a pure data plan. Say “liu liang ka” (traffic card) or show “data-only SIM” on your translator, and staff find the right product. Official shops only sell registered plans with real customer service. Online is where it gets dangerous: dirt-cheap cards labelled wu lian ka (IoT device cards) advertise absurd volume — “100 GB for 10 RMB” listings exist. Those are machine cards meant for water meters and security cameras. They work for a while, then get throttled or simply die, and nobody answers when they do. We have watched these fail mid-trip. Rule: official store, never a marketplace listing.

The twenty-minute store run

Any decent-sized China Mobile, Unicom or Telecom shop works. Walk in with your passport, ask for a data-only card, and staff handle real-name registration on the spot — required by law for every SIM in the country. You pick a plan, pay, and walk out with a working card. Airport arrival halls have carrier counters selling tourist cards from 3 to 15 days; longer card, cheaper daily rate. Stay more than two weeks and a monthly plan from a city store wins.

What it costs, roughly, in 2026

From our price checks this year: airport tourist cards run about 25-40 RMB for three days, 40-70 RMB for a week, 70-110 RMB for fifteen days. City shops sell prepaid monthly plans that are cheaper per gigabyte — typical promotions land around 20-40 RMB a month for 20-60 GB, and foreign passports are welcome. Pay in cash, Alipay or WeChat; no Chinese bank card needed. Ask about auto-renewal — prepaid data dies when credit runs out, and in-store cash top-ups are easiest.

Where the no-number setup runs out

Anything that needs SMS: WeChat, DiDi, Alipay, every banking app, even some mall Wi-Fi, wants a code sent to a phone. A data-only card cannot receive texts, so those doors stay closed. Our standing advice: data-only for a tablet or a short trip, absolutely. For a main phone, take a normal SIM with a number — or run both, which is what dual-SIM phones are for. And for an imported phone, check band support before you rely on it (our separate guide on buying phones in China covers the hardware).

Speed, tethering and the fine print

Official plans include 4G everywhere and 5G in most cities — plenty for video and maps. Trains and rural stretches drop to 4G, and tunnels briefly cut out — normal, not a fault of the card. Tethering is generally allowed on official consumer plans, but ask before buying; some budget cards quietly block it. Keep the SIM with your passport at the border — real-name registration links them. As of late 2026, phone eSIMs are still mostly a watch thing here, so a physical card is the route.

Quick answers

Q: Can I buy a data-only SIM at the airport?
A: Yes. Arrival-hall carrier counters sell tourist data cards to passport holders, 3-15 days, activated on the spot. Roughly 40-70 RMB for a week.

Q: Do I need a Chinese bank card to buy one?
A: No. Cash, Alipay or WeChat Pay work at carrier shops; no local bank account needed to buy or top up.

Q: Can a data-only SIM register WeChat, DiDi or a bank app?
A: No. They need SMS verification codes, and a data-only card cannot receive SMS. Keep a real number for anything you must verify.

Q: What should I buy for a two-month stay?
A: A monthly prepaid city-store plan (typically 20-40 RMB for 20-60 GB) topped up each month beats stacking tourist cards on price and hassle.
