China SIM Card & eSIM Guide 2026: Short Trip or Long Stay
The right way to get connected in China depends far more on how long you're staying than on which carrier you pick. A two-week tourist trip and a two-year work assignment have completely different requirements — data plan, number registration, and how easy top-up is once you're here. This guide breaks it down by trip length so you can pick once and get it right.
Get an eSIM
No store visit, no passport paperwork on arrival, activates before you land. Best for tourists and short business trips.
See eSIM PlansGet a Physical SIM
Cheaper data long-term, a number you can keep across trips, full carrier account. Best for expats, students, and frequent visitors — but also works fine for a short trip if you'd rather have a real phone number than a data-only eSIM.

Best for Short Stays: eSIM
If you're in China for a holiday, a conference, or any trip under about a month, an eSIM is the least hassle. You install it before you leave home, it activates the moment you land, and there's no need to find a carrier store or carry a passport to a service hall on day one. Data-only eSIM plans are the norm — pair one with a messaging app account if you need a local number for calls.
Compatibility first: not every phone supports eSIM, and not every eSIM plan supports every network band in China. Check your handset against the free compatibility checker before buying.
If you'd rather have a physical card, the Talktiko SIM below works well for short trips too — it's plug-and-play as soon as you land, and unlike most eSIMs it comes with a real Chinese phone number. For a deeper dive into eSIM options specifically, see our full eSIM for China guide.
Best for Long Stays: Physical SIM Card
For a stay of three months or more — study, work, or repeat annual visits — a physical SIM is usually the better economics. Per-GB data is cheaper than most eSIM plans, you get a real phone number tied to a carrier account, and (as long as you keep it topped up) you can keep the same number between trips.
There are a few ways to get one, compared in the table below.
The Talktiko SIM comes with a real Chinese phone number, not just a data-only connection — useful if you need to receive OTP texts or make local calls, not just get online. It ships with 30 days' initial validity, which is extendable, and you can recharge data, talk, and text as you go — so it works whether you're staying a few weeks or settling in long-term. If you just need a number for SMS verification without a physical or eSIM card at all, see Virtual China Mobile Numbers.
Want a China SIM with a Hong Kong number as well? My own China prepaid SIM card with an extra Hong Kong number is bought through WeChat and comes as a physical SIM or an eSIM, which suits travelers who also visit Hong Kong.

Registering In Person: Service Hall Directories
If you'd rather register at a carrier counter — often the case for students, expats setting up a long-term plan, or anyone whose passport-registration eSIM order fell through — here are the service hall directories for major cities, with addresses, districts, and hours:
Short Stay vs Long Stay: Quick Comparison

| Keep number between trips | No — typically single-trip | Yes, with regular top-up |
Topping Up Once You're Connected
Whichever option you choose, you'll eventually need to add credit or data. The full walkthrough of every method — carrier app, WeChat/Alipay wallet, in-person at a branch or kiosk, Alipay's Tour Pass, or third-party recharge — is covered in the top-up guide and China Mobile data top up.
Frequently Asked Questions
For trips under about a month, an eSIM is usually simpler — no store visit, no passport registration on arrival, and it activates before you land. For stays of several months or longer, a physical SIM registered in person gives you a more stable long-term number and cheaper per-GB data.
Yes. Real-name registration is mandatory in China for any mobile number, whether prepaid or postpaid. You'll need your passport whether you buy in person at a carrier store or activate certain physical SIMs ordered in advance.
It depends on which network bands your handset supports. Use the free compatibility checker before ordering to confirm your phone works with the carrier and network type you're planning to use.
With a physical SIM, yes, as long as you keep the account topped up during your absence, since inactive prepaid numbers can be reclaimed by the carrier after an extended period with no credit. An eSIM plan is typically single-trip and doesn't preserve a number between visits.
You can top up through the carrier's app, a WeChat or Alipay wallet, in person at a service hall or kiosk, via Alipay's Tour Pass for short-term visitors, or through a third-party recharge service.
Most foreign apps and services are blocked on mainland Chinese networks regardless of which local SIM you use, so many travelers set up a VPN before arrival if they need access to services blocked in China.
Yes. Foreign tourists can buy a prepaid SIM from China Mobile or China Unicom, either at a service hall with a passport or preordered online through a reseller such as Talktiko for delivery on arrival.
A physical SIM is a removable card that gives you a real Chinese phone number for calls, SMS and data, tied to a carrier account you can top up indefinitely. An eSIM is a digital profile installed on your phone, usually data-only, and typically valid for a single trip.
For data-only use on a short trip, an eSIM plan is often simplest. If you also want a real phone number for calls or SMS verification, a physical SIM like Talktiko is comparably priced and includes voice and text, not just data.
